Threat Containment

Threat Centric NAC Service

Threat Centric Network Access Control (TC-NAC) feature enables you to create authorization policies based on the threat and vulnerability attributes received from the threat and vulnerability adapters.

Threat severity levels and vulnerability assessment results can be used to dynamically control the access level of an endpoint or a user.

You can configure the vulnerability and threat adapters to send high-fidelity Indications of Compromise (IoC), Threat Detected events, and CVSS scores to Cisco ISE, so that threat-centric access policies can be created to change the privilege and context of an endpoint accordingly.

Cisco ISE supports the following adapters:

  • SourceFire FireAMP

  • Cognitive Threat Analytics (CTA) adapter

  • Qualys


    Note

    Only the Qualys Enterprise Edition is currently supported for TC-NAC flows.

  • Rapid7 Nexpose

  • Tenable Security Center

When a threat event is detected for an endpoint, you can select the MAC address of the endpoint on the Compromised Endpoints window and apply an ANC policy, such as Quarantine. Cisco ISE triggers CoA for that endpoint and applies the corresponding ANC policy. If ANC policy is not available, Cisco ISE triggers CoA for that endpoint and applies the original authorization policy. You can use the Clear Threat and Vulnerabilities option on the Compromised Endpoints window to clear the threat and vulnerabilities associated with an endpoint (from Cisco ISE system database).

The following attributes are listed under the Threat dictionary:

  • CTA-Course_Of_Action (values can be Internal Blocking, Eradication, or Monitoring)

  • Qualys-CVSS_Base_Score

  • Qualys-CVSS_Temporal_Score

  • Rapid7 Nexpose-CVSS_Base_Score

  • Tenable Security Center-CVSS_Base_Score

  • Tenable Security Center-CVSS_Temporal_Score

The valid range is from 0 to 10 for both Base Score and Temporal Score attributes.

When a vulnerability event is received for an endpoint, Cisco ISE triggers CoA for that endpoint. However, CoA is not triggered when a threat event is received.

You can create an authorization policy by using the vulnerability attributes to automatically quarantine the vulnerable endpoints based on the attribute values. For example: 

Any Identity Group & Threat:Qualys-CVSS_Base_Score > 7.0 -> Quarantine

To view the logs of an endpoint that is automatically quarantined during CoA events, choose Operations > Threat-Centric NAC Live Logs. To view the logs of an endpoint that is quarantined manually, choose Operations > Reports > Audit > Change Configuration Audit.

Note the following points while enabling the Threat Centric NAC service:

  • The Threat Centric NAC service requires a Cisco ISE Premier license.

  • Threat Centric NAC service can be enabled on only one node in a deployment.

  • You can add only one instance of an adapter per vendor for Vulnerability Assessment service. However, you can add multiple instances of FireAMP adapter.

  • You can stop and restart an adapter without losing its configuration. After configuring an adapter, you can stop the adapter at any point of time. The adapter would remain in this state even when the ISE services are restarted. Select the adapter and click Restart to start the adapter again.


    Note

    When an adapter is in Stopped state, you can edit only the name of the adapter instance; you cannot edit the adapter configuration or the advanced settings.

You can view the threat information for the endpoints on the following pages:

  • Home page > Threat dashboard

  • Context Visibility > Endpoints > Compromised Endpoints

The following alarms are triggered by the Threat Centric NAC service:

  • Adapter not reachable (syslog ID: 91002): Indicates that the adapter cannot be reached.

  • Adapter Connection Failed (syslog ID: 91018): Indicates that the adapter is reachable but the connection between the adapter and source server is down.

  • Adapter Stopped Due to Error (syslog ID: 91006): This alarm is triggered if the adapter is not in the desired state. If this alarm is displayed, check the adapter configuration and server connectivity. Refer to the adapter logs for more details.

  • Adapter Error (syslog ID: 91009): Indicates that the Qualys adapter is unable to establish a connection with or download information from the Qualys site.

The following reports are available for the Threat Centric NAC service:

  • Adapter Status: The Adapter Status report displays the status of the threat and vulnerability adapters.

  • COA Events: When a vulnerability event is received for an endpoint, Cisco ISE triggers CoA for that endpoint. The CoA Events report displays the status of these CoA events. It also displays the old and new authorization rules and the profile details for these endpoints.

  • Threat Events: The Threat Events report provides a list of all the threat events that Cisco ISE receives from the various adapters that you have configured. Vulnerability Assessment events are not included in this report.

  • Vulnerability Assessment: The Vulnerability Assessment report provides information about the assessments that are happening for your endpoints. You can view this report to check if the assessment is happening based on the configured policy.

You can view the following information from Operations > Reports > Diagnostics > ISE Counters > Threshold Counter Trends:

  • Total number of events received

  • Total number of threat events

  • Total number of vulnerability events

  • Total number of CoAs issued (to PSN)

The values for these attributes are collected every 5 minutes, so these values represent the count for the last 5 minutes.

The Threat dashboard contains the following dashlets:

  • Total Compromised Endpoints dashlet displays the total number of endpoints (both connected and disconnected endpoints) that are currently impacted on the network.

  • Compromised Endpoints Over Time dashlet displays a historical view of the impact on endpoints for the specified time period.

  • Top Threats dashlet displays the top threats based on the number of endpoints impacted and the severity of the threat.

  • You can use the Threats Watchlist dashlet to analyze the trend of selected events.

The size of the bubbles in the Top Threats dashlet indicates the number of endpoints impacted and the light shaded area indicates the number of disconnected endpoints. The color as well as the vertical scale indicate the severity of the threat. There are two categories of threat—Indicators and Incidents. The severity attribute for Indicator is "Likely_Impact" and the severity attribute for Incident is "Impact_Qualification".

The Compromised Endpoint window displays the matrix view of the endpoints that are impacted and the severity of the impact for each threat category. You can click on the device link to view the detailed threat information for an endpoint.

The Course Of Action chart displays the action taken (Internal Blocking, Eradication, or Monitoring) for the threat incidents based on the CTA-Course_Of_Action attribute received from the CTA adapter.

The Vulnerability dashboard on the Home page contains the following dashlets:

  • Total Vulnerable Endpoints dashlet displays the total number of endpoints that have a CVSS score greater than the specified value. Also displays the total number of connected and disconnected endpoints that have a CVSS score greater than the specified value.

  • Top Vulnerability dashlet displays the top vulnerabilities based on the number of endpoints impacted or the severity of the vulnerability. The size of the bubbles in the Top Vulnerability dashlet indicates the number of endpoints impacted and the light shaded area indicates the number of disconnected endpoints. The color as well as the vertical scale indicates the severity of the vulnerability.

  • You can use the Vulnerability Watchlist dashlet to analyze the trend of selected vulnerabilities over a period of time. Click the search icon in the dashlet and enter the vendor-specific id ("qid" for Qualys ID number) to select and view the trend for that particular ID number.

  • The Vulnerable Endpoints Over Time dashlet displays a historical view of the impact on endpoints over time.

The Endpoint Count By CVSS graph on the Vulnerable Endpoints window shows the number of endpoints that are affected and their CVSS scores. You can also view the list of affected endpoints on the Vulnerable Endpoints window. You can click the device link to view the detailed vulnerability information for each endpoint.

Threat Centric NAC service logs are included in the support bundle. Threat Centric NAC service logs are located at support/logs/TC-NAC/

    • 4 - Damaging

    • 5 - Catastrophic

    For example, if you have selected "3-Painful", incidents with this severity level (3-Painful) and above (in this case, 4-Damaging and 5-Catastrophic) are polled.

  • Logging level: Choose a log level for the adapter. The available options are: Error, Info, and Debug.

Step 11

Click Finish.


Note

CTA works with user identities listed in the web proxy logs as IP addresses or usernames. Specifically, in the case of IP addresses, the IP address of a device that is available through the proxy logs may collide with the IP address of another device on the internal network. For example, roaming users connected via AnyConnect and a split-tunnel directly to the internet could acquire a local IP range address (for example, 10.0.0.X address), which may collide with an address in an overlapping private IP range used in an internal network. We recommend that you take into account the logical network architecture while defining the policies to avoid quarantine actions being applied on mismatched devices.

Configure Authorization Profiles for CTA Adapter

For each threat event, the CTA adapter returns one of the following values for the Course of Action attribute: Internal Blocking, Monitoring, or Eradication. You can create authorization profiles based on these values.

Procedure

Step 1

In the Cisco ISE GUI, click the Menu icon () and choose Policy > Policy Elements > Authorization > Authorization Profiles.

Step 2

Click Add.

Step 3

Enter a name and description for the authorization profile.

Step 4

Select the Access Type.

Step 5

Enter the required details and click Submit.

Configure Authorization Policy using the Course of Action Attribute

You can use the CTA-Course_Of_Action attribute to configure authorization policies for the endpoints for which threat events are reported. This attribute is available in the Threat directory.

You can also create exception rules based on the CTA-Course_Of_Action attribute.

Procedure

Step 1

Choose Policy > Policy Sets

You can edit an existing policy rule or create a new exception rule for the endpoints with threat events.

Step 2

Create a condition to check for the CTA-Course_Of_Action attribute value and assign the appropriate authorization profile. For example:

Network_Access_Authentication_Passed AND ThreatCTA-Course_Of_Action CONTAINS Internal Blocking then blocking (authorization profile)

Note

 

"Internal Blocking" is the recommended Course of Action attribute to be used for quarantining the endpoints.

Step 3

Click Save.

When a threat event is received for an endpoint, Cisco ISE checks if there is any matching authorization policy for the endpoint and triggers CoA only if the endpoint is active. If the endpoint is offline, threat event details are added to the Threat Events report (Operations > Reports > Threat Centric NAC > Threat Events).

Note

Sometimes CTA sends multiple risks and their associated Course of Action attributes in one incident. For example, it can send "Internal Blocking" and "Monitoring" (course of action attributes) in one incident. In this case, if you have configured an authorization policy to quarantine endpoints using "equals" operator, the endpoints will not be quarantined. For example:

CTA-Course_Of_Action EQUALS Internal Blocking then Quarantine_Systems (authorization profile)

In such cases, you must use "contains" operator in the authorization policy to quarantine the endpoints. For example:

CTA-Course_Of_Action CONTAINS Internal Blocking then Quarantine_Systems

Support for Vulnerability Assessment in Cisco ISE

Cisco ISE integrates with the following Vulnerability Assessment (VA) Ecosystem Partners to obtain vulnerability results of endpoints that connect to the Cisco ISE network:

  • Qualys: Qualys is a cloud-based assessment system with scanner appliances deployed in the network. Cisco ISE allows you to configure an adapter that communicates with Qualys and obtains the VA results. You can configure the adapter from the Admin portal. You need a Cisco ISE administrator account with Super Admin privileges to configure the adapter. The Qualys adapter uses REST APIs to communicate with the Qualys Cloud Service. You need a user account in Qualys with Manager privileges to access the REST APIs. Cisco ISE uses following Qualys REST APIs:

    • Host Detection List API: To check the last scan results of the endpoint

    • Scan API: To trigger an on-demand scan of the endpoint

    Qualys enforces limits on the number of API calls that subscribed users can make. The default rate limit count is 300 per 24 hours. Cisco ISE uses Qualys API version 2.0 to connect to Qualys. Refer to the Qualys API V2 User Guide for more information on these API functions.

  • Rapid7 Nexpose: Cisco ISE integrates with Rapid 7 Nexpose, a vulnerability management solution, to help detect vulnerabilities and enables you to respond to such threats quickly. Cisco ISE receives the vulnerability data from Nexpose and based on the policies that you configure in ISE, it quarantines the affected endpoints. From the Cisco ISE dashboard, you can view the affected endpoint and take appropriate action.

    Cisco ISE has been tested with Nexpose Release 6.4.1.

  • Tenable Security Center (Nessus scanner): Cisco ISE integrates with Tenable Security Center and receives the vulnerability data from Tenable Nessus scanner (managed by Tenable Security Center) and based on the policies that you configure in ISE, it quarantines the affected endpoints. From the Cisco ISE dashboard, you can view the affected endpoints and take appropriate action.

    Cisco ISE has been tested with Tenable Security Center 5.3.2.

The results from the ecosystem partner are converted in to a Structured Threat Information Expression (STIX) representation and based on this value, a Change of Authorization (CoA) is triggered, if needed, and the appropriate level of access is granted to the endpoint.

The time taken to assess endpoints for vulnerabilities depends on various factors and hence VA cannot be performed in real time. The factors that affect the time taken to assess an endpoint for vulnerabilities include:

  • Vulnerability assessment ecosystem

  • Type of vulnerabilities scanned for

  • Type of scans enabled

  • Network and system resources allocated by the ecosystem for the scanner appliances

In this release of Cisco ISE, only endpoints with IPv4 addresses can be assessed for vulnerabilities.

The authorization profile in Cisco ISE now includes an option to scan endpoints for vulnerabilities. You can choose to run the scan periodically and also specify the time interval for these scans. After you define the authorization profile, you can apply it to an existing authorization policy rule or create a new authorization policy rule.

Before you begin

You must have enabled the Threat Centric NAC service and configured a vendor adapter.

Procedure

Step 1

In the Cisco ISE GUI, click the Menu icon () and choose Policy > Policy Elements > Authorization > Authorization Profiles.

Step 2

Create a new authorization profile or edit an existing profile.

Step 3

From the Common Tasks area, check the Assess Vulnerabilities check box.

Step 4

From the Adapter Instance drop-down list, choose the vendor adapter that you have configured. For example, Qualys_Instance.

Step 5

Enter the scan interval in hours in the Trigger scan if the time since last scan is greater than text box. Valid range is between 1 and 9999.

Step 6

Check the Assess periodically using above interval check box.

Step 7

Click Submit.

Configure Exception Rule to Quarantine a Vulnerable Endpoint

You can use the following Vulnerability Assessment attributes to configure an exception rule and provide limited access to vulnerable endpoints:

  • Threat:Qualys-CVSS_Base_Score

  • Threat:Qualys-CVSS_Temporal_Score

  • Rapid7 Nexpose-CVSS_Base_Score

  • Tenable Security Center-CVSS_Base_Score

  • Tenable Security Center-CVSS_Temporal_Score

These attributes are available in the Threat directory.

You can choose to quarantine the endpoint, provide limited access (redirect to a different portal), or reject the request.

Procedure

Step 1

Choose Policy > Policy Sets.

You can edit an existing policy rule or create a new exception rule to check for VA attributes.

Step 2

Create a condition to check for the Qualys score and assign the appropriate authorization profile. For example:

Any Identity Group & Threat:Qualys-CVSS_Base_Score > 5 -> Quarantine (authorization profile)

Step 3

Click Save.

Vulnerability Assessment Logs

Cisco ISE provides the following logs for troubleshooting VA services.

  • vaservice.log—Contains VA core information and is available in the node that runs the TC-NAC service.

  • varuntime.log—Contains information about the endpoint and the VA flow; is available in the Monitoring node and the node that runs the TC-NAC service.

  • vaaggregation.log—Contains hourly aggregation details about the endpoint vulnerability and is available in the Primary Administration Node.

common-name#issuer#nnnnn

Status

Choose Enabled or Disabled from the drop-down list. If the certificate is disabled, Cisco ISE will not use the certificate for establishing trust.

Description

(Optional) Enter a description.

Usage

Trust for authentication within ISE

Check this check box if you want this certificate to verify server certificates (from other Cisco ISE nodes or LDAP servers).

Trust for client authentication and Syslog

(Applicable only if you check the Trust for authentication within ISE check box) Check the check box if you want this certificate to be used to:

  • Authenticate endpoints that connect to Cisco ISE using the EAP protocol.

  • Trust a Syslog server.

Trust for certificate based admin authentication

You can check this check box only when Trust for client authentication and Syslog is selected.

Check this check box to enable usage for certificate-based authentications for admin access. Import the required certificate chains into the Trusted Certificate store.

Trust for authentication of Cisco Services

Check this check box if you want this certificate to be used to trust external Cisco services such as the Feed Service.

Certificate Status Validation

Cisco ISE supports two ways of checking the revocation status of a client or server certificate that is issued by a particular CA. The first way is to validate the certificate using the Online Certificate Status Protocol (OCSP), which makes a request to an OCSP service maintained by the CA. The second way is to validate the certificate against a CRL which is downloaded from the CA into Cisco ISE. Both of these methods can be enabled, in which case OCSP is used first and only if a status determination cannot be made then the CRL is used.

Validate Against OCSP Service

Check the check box to validate the certificate against OCSP services. You must first create an OCSP Service to be able to check this box.

Reject the request if OCSP returns UNKNOWN status

Check the check box to reject the request if certificate status is not determined by the OCSP service. If you check this check box, an unknown status value that is returned by the OCSP service causes Cisco ISE to reject the client or server certificate currently being evaluated.

Reject the request if OCSP Responder is unreachable

Check the check box for Cisco ISE to reject the request if the OCSP Responder is not reachable.

Download CRL

Check the check box for the Cisco ISE to download a CRL.

CRL Distribution URL

Enter the URL to download the CRL from a CA. This field is automatically populated if it is specified in the certificate authority certificate. The URL must begin with “http”, “https”, or “ldap.”

Retrieve CRL

The CRL can be downloaded automatically or periodically. Configure the time interval between downloads.

If download failed, wait

Configure the time interval that Cisco ISE must wait Cisco ISE tries to download the CRL again.

Bypass CRL Verification if CRL is not Received

Check this check box, for the client requests to be accepted before the CRL is received. If you uncheck this check box, all client requests that use certificates signed by the selected CA will be rejected until Cisco ISE receives the CRL file.

Ignore that CRL is not yet valid or expired

Check this check box if you want Cisco ISE to ignore the start date and expiration date and continue to use the not yet active or expired CRL and permit or reject the EAP-TLS authentications based on the contents of the CRL.

Uncheck this check box if you want Cisco ISE to check the CRL file for the start date in the Effective Date field and the expiration date in the Next Update field. If the CRL is not yet active or has expired, all authentications that use certificates signed by this CA are rejected.

    Cisco ISE displays a sample SGT name in the Example Name field, based on your selections.

    If an SGT exists with the same name, ISE appends _x to the SGT name, where x is the first value, starting with 1 (if 1 is not used in the current name). If the new name is longer than 32 characters, Cisco ISE truncate its to the first 32 characters.

IP SGT static mapping of hostnames

IP SGT Static Mapping of Hostnames: If you use FQDN and hostnames, Cisco ISE looks for the corresponding IP addresses in the PAN and PSN nodes while deploying the mappings and checking the deployment status. You can use this option to specify the number of mappings that are created for the IP addresses returned by the DNS query. You can select one of the following options:

  • Create mappings for all IP addresses returned by a DNS query

  • Create mappings only for the first IPv4 address and the first IPv6 address that is returned by a DNS query

TrustSec HTTP Service for Network Devices

  • Enable HTTP Service: Use HTTP to transfer Trustsec data to network devices over port 9063.

  • Include entire response payload body in Audit: Enable this option to display the entire TrustSec HTTP response payload body in the audit logs. This option may dramatically decrease performance. When this option is disabled, only HTTP headers, status, and authentication information are logged.

Network Resources

Support for Session Aware Networking (SAnet)

Cisco ISE provides limited support for Session Aware Networking (SAnet). SAnet is a session management framework that runs on many Cisco switches. SAnet manages access sessions, including visibility, authentication, and authorization. SAnet uses a service template, which contains RADIUS authorization attributes. Cisco ISE includes a service template inside an authorization profile. Cisco ISE identifies service templates in an authorization profile using a flag that identifies the profile as “Service Template” compatible.

Cisco ISE authorization profiles contain RADIUS authorization attributes that are transformed into a list of attributes. SAnet service templates also contain of RADIUS authorization attributes, but those attributes are not transformed into a list.

For SAnet devices, Cisco ISE sends the name of the service template. The device downloads the content of the service template, unless it already has that content in a cache or statically defined configuration. Cisco ISE sends a CoA notification to the device when a service template changes RADIUS attributes.

Network Devices

IP Address or IP Range

Choose one of the following from the drop-down list and enter the required values in the fields displayed:

  • IP Address: Enter a single IP address (IPv4 or IPv6 address) and a subnet mask.

  • IP Range: Enter the required IPv4 address range. To exclude IP addresses during authentication, enter an IP address or IP address range in the Exclude field.

The following are the guidelines for defining the IP addresses and subnet masks, or IP address ranges:

  • You can define a specific IP address, or an IP range with a subnet mask. If device A has an IP address range defined, you can configure another device, B, with an individual address from the range that is defined in device A.

  • You can define IP address ranges in all the octets. You can use a hyphen (-) or an asterisk (*) as wildcard to specify a range of IP addresses. For example, *.*.*.*, 1-10.1-10.1-10.1-10, or 10-11.*.5.10-15.

  • You can exclude a subset of IP address range from the configured range in a scenario where that subset has already been added, for example, 10.197.65.*/10.197.65.1, or 10.197.65.* exclude 10.197.65.1.

  • You can configure up to 40 IP addresses or IP ranges for each network device.

  • You cannot define two devices with the same specific IP addresses.

  • You cannot define two devices with the same IP range. The IP ranges must not overlap either partially or completely.

Device Profile

Choose the vendor of the network device from the drop-down list.

Use the tooltip next to the drop-down list to see the flows and services that the selected vendor's network devices support. The tooltip also displays the RADIUS Change of Authorization (CoA) port and type of URL redirect that is used by the device. These attributes are defined in the device type's network device profile.

Model Name

Choose the device model from the drop-down list.

Use the model name as one of the parameters while checking for conditions in rule-based policies. This attribute is present in the device dictionary.

Shared Secret

Enter the shared secret for the network device.

The shared secret is the key that is configured on the network device using the radius-host command with the pac option.

Note

 

The length of the shared secret must be equal to or greater than the value configured in the Minimum RADIUS Shared Secret Length field in the Device Security Settings window (Administration > Network Resources > Network Devices > Device Security Settings).

For a RADIUS server, the best practice is to have 22 characters. For new installations and upgraded deployments, the shared secret length is four characters by default. You can change this value in the Device Security Settings window.

Use Second Shared Secret

Specify a second shared secret to be used by the network device and Cisco ISE.

Note

 

Although Cisco TrustSec devices can take advantage of the dual shared secrets (keys), Cisco TrustSec CoA packets sent by Cisco ISE will always use the first shared secret (key). To enable the use of the second shared secret, choose the Cisco ISE node from which the Cisco TrustSec CoA packets must be sent to the Cisco TrustSec device. Configure the Cisco ISE node to be used for this task in the Send From drop-down list in the Work Centers > Device Administration > Network Resources > Network Devices > Add > Advanced TrustSec Settings window. You can select a primary administration node (PAN) or a policy service node (PSN). If the chosen PSN node is down, the PAN sends the Cisco TrustSec CoA packets to the Cisco TrustSec device.

Note

 

The Second Shared Secret feature for RADIUS Access Request works only for packets containing the Message-Authenticator field.

CoA Port

Specify the port to be used for RADIUS CoA.

The default CoA port for the device is defined in the network device profile that is configured for a network device (Administration > Network Resources > Network Device Profiles > Network Resources > Network Device Profiles). Click Set To Default to use the default CoA port.

Note

 

If you modify the CoA port specified in the Network Devices window (Administration > Network Resources > Network Devices) under RADIUS Authentication Settings, make sure that you specify the same CoA port for the corresponding profile in the Network Device Profile window (Administration > Network Resources > Network Device Profiles).

Device Portal Management

Configure Device Portal Settings

Portal Identification Settings for Device Portals

To view this window, click the Menu icon () and choose Administration > Device Portal Managment > Blocked List Portal, Client Provisioning Portals, BYOD Portals, MDM Portals, or My Device Portals > Create, Edit or Duplicate > Portals Settings and Customization.

  • Portal Name: Enter a unique portal name to access this portal. Do not use this portal name for any other Sponsor, Guest, or nonguest portals, such as Blocked List, Bring Your Own Device (BYOD), Client Provisioning, Mobile Device Management (MDM), or My Devices portals.

    This name appears in the authorization profile portal selection for redirection choices. It is applied to the list of portals for easy identification among other portals.

  • Description: Optional.

  • Portal Test URL: A system-generated URL displays as a link after you click Save. Use it to test the portal.

    Click the link to open a new browser tab that displays the URL for this portal. Policy Services Node (PSN) with Policy Services must be turned on. If Policy Services are disabled, the PSN only displays the Admin portal.


    Note

    The test portal does not support RADIUS sessions, so you won't see the entire portal flow for all portals. BYOD and Client Provisioning are examples of portals that depend on RADIUS sessions. For example, a redirect to an external URL will not work. If you have more than one PSN, Cisco ISE chooses the first active PSN.

  • Language File: Each portal type supports 15 languages by default, which are available as individual properties files bundled together in a single zipped language file. Export or import the zipped language file to use with the portal. The zipped language file contains all the individual language files that you can use to display text for the portal.

    The language file contains the mapping to the particular browser locale setting along with all of the string settings for the entire portal in that language. A single language file contains all the supported languages, so that it can easily be used for translation and localization purposes.

    If you change the browser locale setting for one language, the change is applied to all the other end-user web portals. For example, if you change the French.properties browser locale from fr,fr-fr,fr-ca to fr,fr-fr in the Hotspot Guest portal, the changes also apply to the My Devices portal.

    An alert icon displays when you customize any of the text on the Portal Page Customizations tab. The alert message reminds you that any changes made to one language while customizing the portal must also be added to all the supported languages properties files. You can manually dismiss the alert icon using the drop-down list option; or it is automatically dismissed after you import the updated zipped language file.

Portal Settings for BYOD and MDM Portals

To view this window, click the Menu icon () and choose Administration > Device Portal Management > BYOD Portals or MDM Portals > Create, Edit or Duplicate > Portal Behavior and Flow Settings > Portal Settings.

Configure these settings to define portal page operations.

  • HTTPS Port: Enter a port value between 8000 to 8999; the default value is 8443 for all the default portals, except the Blocked List Portal, which is 8444. If you upgraded with port values outside this range, they are honored until you modify this window. If you modify this window, update the port setting to comply with this restriction.

    If you assign ports used by a non-guest (such as My Devices) portal to a guest portal, an error message appears.

    For posture assessments and remediation only, the Client Provisioning portal also uses ports 8905 and 8909. Otherwise, it uses the same ports assigned to the Guest portal.

    Portals assigned to the same HTTPS port can use the same Gigabit Ethernet interface or another interface. If they use the same port and interface combination, they must use the same certificate group tag. For example:

    • Valid combinations include, using the Sponsor portal as an example:

      • Sponsor portal: Port 8443, Interface 0, Certificate tag A and My Devices portal: Port 8443, Interface 0, Certificate group A.

      • Sponsor portal: Port 8443, Interface 0, Certificate group A and My Devices portal: Port 8445, Interface 0, Certificate group B.

      • Sponsor portal: Port 8444, Interface 1, Certificate group A and Blocked List portal: Port 8444, Interface 0, Certificate group B.

    • Invalid combinations include:

      • Sponsor portal: Port 8443, Interface 0, Certificate group A and My Devices portal: 8443, Interface 0, Certificate group B.

      • Sponsor portal: Port 8444, Interface 0, Certificate tag A and Blocked List portal: Port 8444, Interface 0, Certificate group A.


    Note

    We recommend that you use interface 0 for Guest services for best performance. You can either configure only interface 0 in the Portal Settings, or you can use the CLI command ip host to map a hostname or FQDN to the IP address of interface 0.

  • Allowed Interfaces: Select the PSN interfaces which a PAN can use to run a portal. When a request to open a portal is made on the PAN, the PAN looks for an available allowed port on the PSN. You must configure the Ethernet interfaces using IP addresses on different subnets.

    These interfaces must be available on all the PSNs, including VM-based ones, that have Policy Services turned on. This is a requirement because any of these PSNs can be used for the redirect at the start of the guest session.

    • The Ethernet interfaces must use IP addresses on different subnets.

    • The interfaces you enable here must be available on all your PSNs, including VM-based ones when Policy Services turned on. This is required because any of these PSNs can be used for a redirect at the start of the guest session.

    • The portal certificate Subject Name or Alternate Subject Name must resolve to the interface IP address.

    • Configure ip host x.x.x.x yyy.domain.com in Cisco ISE CLI to map the secondary interface IP address to the FQDN, which is used to match the certificate Subject Name or Alternate Subject Name.

    • If only the bonded NIC is selected, when the PSN attempts to configure the portal it first attempts to configure the Bond interface. If that is not successful, perhaps because there was no bond setup on that PSN, then the PSN logs an error and exits. The PSN will not try to start the portal on the physical interface.

    • NIC Teaming or bonding is a configuration option that allows you to configure two individual NICs for high availability (fault tolerance). If one of the NICs fails, the other NIC that is part of the bonded connection continues the connection. A NIC is selected for a portal based in the Portal Settings configuration. If both physical NICs and the corresponding bonded NIC are configured, when the PSN attempts to configure the portal, it first attempts to connect to the Bond interface. If that is not successful, perhaps because there was no bond setup on that PSN, then the PSN attempts to start the portal on the physical interface.

  • Certificate Group tag: Pick a certificate group tag that specifies the certificate to be used for the portal’s HTTPS traffic.

  • Endpoint Identity Group: Choose an endpoint identity group to track guest devices. Cisco ISE provides the GuestEndpoints endpoint identity group to use as a default. You can also create more endpoint identity groups if you choose to not use the default.

    Choose an endpoint identity group to track employee devices. Cisco ISE provides the RegisteredDevices endpoint identity group to use as a default. You can also create more endpoint identity groups if you choose to not use the default.

  • Display Language

    • Use Browser Locale: Use the language specified in the client browser's locale setting as the display language of the portal. If browser locale's language is not supported by Cisco ISE, then the Fallback Language is used as the language portal.

    • Fallback Language: Choose the language to use when the language cannot be obtained from the browser locale, or if the browser locale language is not supported by Cisco ISE.

    • Always Use: Choose the display language to use for the portal. This setting overrides the User Browser Locale option.

Field Name Usage Guidelines

Include an AUP (on page/as link)

Display your company’s network-usage terms and conditions, either as text on the window currently being displayed for the user or as a link that opens a new tab or window with AUP text.

Require Acceptance

Require users to accept an AUP before their account is fully enabled. The Login button is not enabled unless the user accepts the AUP. If users do not accept the AUP, they will not obtain network access.

Require scrolling to end of AUP

This option displays only if Include an AUP on page is enabled.

Ensure that the user has read the AUP completely. The Accept button is enabled only after the user has scrolled to the end of the AUP.

Display Device ID Field During Registration

Display the device ID to the user during the registration process, even though the device ID is pre-configured and cannot be changed while using the BYOD portal.

Originating URL

After successfully authenticating to the network, redirect the user’s browser to the original website that the user is trying to access, if available. If not available, the Authentication Success window appears. Make sure that the redirect URL is allowed to work on port 8443 of the PSN by the access-control list on the NAD and by authorization profiles configured in Cisco ISE for that NAD.

For Windows, MAC, and Android devices, control is given to the Self-Provisioning Wizard app, which does provisioning. Therefore, these devices are not redirected to the originating URL. However, iOS (dot1X) and unsupported devices (that are allowed network access) are redirected to this URL.

Success page

Display a page indicating that the device registration was successful.

URL

After successfully authenticating to the network, redirect the user's browser to the specified URL, such as your company’s website.


Note

If you redirect a Guest to an external URL after authentication, there may be a delay while the URL address is resolved and the session is redirected.

Portal Settings for Certificate Provisioning Portal

To view this window, click the Menu icon () and choose Administration > Device Portal Management > Certificate Provisioning Portal > Create, Edit or Duplicate > Portal Behavior and Flow Settings > Portal Settings.

  • HTTPS Port: Enter a port value between 8000 to 8999; the default value is 8443 for all the default portals, except the Blocked List Portal, which is 8444. If you upgraded with port values outside this range, they are honored until you modify this window. If you modify this window, update the port setting to comply with this restriction.

    If you assign ports used by a non-guest (such as My Devices) portal to a guest portal, an error message appears.

    For posture assessments and remediation only, the Client Provisioning portal also uses ports 8905 and 8909. Otherwise, it uses the same ports assigned to the Guest portal.

    Portals assigned to the same HTTPS port can use the same Gigabit Ethernet interface or another interface. If they use the same port and interface combination, they must use the same certificate group tag. For example:

    • Valid combinations include, using the Sponsor portal as an example:

      • Sponsor portal: Port 8443, Interface 0, Certificate tag A and My Devices portal: Port 8443, Interface 0, Certificate group A.

      • Sponsor portal: Port 8443, Interface 0, Certificate group A and My Devices portal: Port 8445, Interface 0, Certificate group B.

      • Sponsor portal: Port 8444, Interface 1, Certificate group A and Blocked List portal: Port 8444, Interface 0, Certificate group B.

    • Invalid combinations include:

      • Sponsor portal: Port 8443, Interface 0, Certificate group A and My Devices portal: 8443, Interface 0, Certificate group B.

      • Sponsor portal: Port 8444, Interface 0, Certificate tag A and Blocked List portal: Port 8444, Interface 0, Certificate group A.


    Note

    We recommend that you use interface 0 for Guest services for best performance. You can either configure only interface 0 in the Portal Settings, or you can use the CLI command ip host to map a hostname or FQDN to the IP address of interface 0.

  • Allowed Interfaces: Select the PSN interfaces which a PAN can use to run a portal. When a request to open a portal is made on the PAN, the PAN looks for an available allowed port on the PSN. You must configure the Ethernet interfaces using IP addresses on different subnets.

    These interfaces must be available on all the PSNs, including VM-based ones, that have Policy Services turned on. This is a requirement because any of these PSNs can be used for the redirect at the start of the guest session.

    • The Ethernet interfaces must use IP addresses on different subnets.

    • The interfaces you enable here must be available on all your PSNs, including VM-based ones when Policy Services turned on. This is required because any of these PSNs can be used for a redirect at the start of the guest session.

  • Certificate Group tag: Pick a certificate group tag that specifies the certificate to be used for the portal’s HTTPS traffic.

  • Authentication Method: Choose which identity source sequence or Identity Provider (IdP) to use for user authentication. The identity source sequence is a list of identity stores that are searched in sequence to verify user credentials.

    Cisco ISE includes a default identity source sequence for sponsor portals, Sponsor_Portal_Sequence.

    To configure IdP, choose Administration > Identity Management > External Identity Sources > SAML Id Providers.

    To configure an identity source sequence, choose Administration > Identity Management > Identity Source Sequences.

  • Configure authorized groups: Choose the user identity groups to which you want to grant permission to generate certificates and move them to the Chosen box.

  • Fully Qualified Domain Name (FQDN): Enter at least one unique FQDN or hostname for the Sponsor or MyDevices portal. For example, you can enter sponsorportal.yourcompany.com,sponsor, so that when the user enters either of those into a browser, the sponsor portal displays. Separate names with commas, but do not include spaces between entries.

    If you change the default FQDN, then also do the following:

    • Update your DNS so that the FQDN of the new URL resolves to a valid Policy Services Node (PSN) IP address. Optionally, this address could point to a load balancer virtual IP address that serves a pool of PSNs.

    • To avoid certificate warning messages due to name mismatches, include the FQDN of the customized URL, or a wildcard, in the subject alternative name (SAN) attribute of the local server certificate of the Cisco ISE PSN. If the Allow Kerberos SSO option is enabled for the sponsor portal, you must include the FQDN of the Cisco ISE PSN, or a wildcard, in the SAN attribute of the local server certificate used by the portal.

  • Idle Timeout: Enter the time in minutes that you want Cisco ISE to wait before it logs out the user if there is no activity in the portal. The valid range is from 1 to 30 minutes.

Login Page Settings

  • Maximum Failed Login Attempts Before Rate Limiting: Specify the number of failed login attempts from a single browser session before Cisco ISE starts to throttle that account. This does not cause an account lockout. The throttled rate is configured in Time between login attempts when rate limiting.

If you upgraded with port values outside this range, they are honored until you make any change to this page. If you make any change to this page, you must update the port setting to comply with this restriction.

  • Allowed Interfaces: Select the PSN interfaces which can run a portal. Only a PSN with an available allowed interface on a PSN can create a portal. You can configure any combination of physical and bonded interfaces. This is a PSN-wide configuration; all portals can only run on these interfaces, this interface configuration is pushed to all the PSNs.

    • You must configure the Ethernet interfaces using IP addresses on different subnets.

    • The interfaces you enable here must be available on all your PSNs, including VM-based ones when Policy Services turned on. This is required because any of these PSNs can be used for a redirect at the start of the guest session.

    • The portal certificate Subject Name/Alternate Subject Name must resolve to the interface IP.

    • Configure ip host x.x.x.x yyy.domain.com in ISE CLI to map secondary interface IP to FQDN, which will be used to match Certificate Subject Name/Alternate Subject Name.

    • If only the bonded NIC is selected, when the PSN attempts to configure the portal it first attempts to configure the Bond interface. If that is not successful, perhaps because there was no bond set upon that PSN, then the PSN logs an error and exits. It will NOT attempt to start the portal on the physical interface.

    • NIC Teaming or bonding is an O/S configuration option that allows you to configure two individual NICs for high availability (fault tolerance). If one of the NICs fails, the other NIC that is part of the bonded connection continues the connection. A NIC is selected for a portal based on the portal settings configuration:

      • If both physical NICs and the corresponding bonded NIC are configured - When the PSN attempts to configure the portal, it first attempts to connect to the Bond interface. If that is not successful, perhaps because there was no bond setup on that PSN, then the PSN attempts to start the portal on the physical interface.

  • Certificate Group Tag: Select the group tag of the certificate group to use for the portal’s HTTPS traffic.

  • Authentication Method: Choose which identity source sequence (ISS) or Identity Provider (IdP) to use for user authentication. The ISS is a list of Identity Stores that are searched in sequence to verify user credentials. Some examples include: Internal Guest Users, Internal Users, Active Directory, and LDAP.

    Cisco ISE includes a default client provisioning Identity Source Sequence for Client Provisioning Portals, Certificate_Request_Sequence.

  • Fully Qualified Domain Name (FQDN): Enter at least one unique FQDN and/or hostname for your Client Provisioning portal. For example, you can enter provisionportal.yourcompany.com, so that when the user enters either of those into a browser, they will reach the Client Provisioning Portal.

    • Update DNS to ensure that the FQDN of the new URL resolves to a valid Policy Services Node (PSN) IP address. Optionally, this address could point to a load balancer virtual IP address that serves a pool of PSNs.

    • To avoid certificate warning messages due to name mismatches, include the FQDN of the customized URL, or a wildcard, in the subject alternative name (SAN) attribute of the local server certificate of the Cisco ISE PSN.


    Note

    For Client Provisioning without URL redirection, the portal name that is entered in the Fully Qualified Domain Name (FQDN) field must be configured in the DNS configuration. This URL must be communicated to the users to enable Client Provisioning without URL redirection.

  • Idle Timeout: Enter the time in minutes that you want Cisco ISE to wait before it logs out the user if there is no activity in the portal. The valid range is from 1 to 30 minutes..


Note

In the Client Provisioning Portal, you can define the port number and the certificate so that the host allows you to download the same certificate for Client Provisioning and Posture. If the portal certificate is signed by the officials certificate authority, you will not receive any security warning. If the certificate is self-signed, you will receive one security warning for both the portals and Cisco AnyConnect Posture component.

Field Name Usage Guidelines

Lost

Enable employees to indicate that their device is lost. This action updates the device status in the My Devices portal to Lost and adds the device to the Blocked List endpoint identity group.

Reinstate

This action reinstates a block listed, lost or stolen device and resets it status to its last known value. This action resets the status of a stolen device to Not Registered, since it has to undergo additional provisioning before it can connect to the network.

If you want to prevent employees reinstating devices that you have block listed, do not enable this option in the My Devices portal.

Delete

Enable employees to delete a registered device from the My Devices portal or to delete unused and add new devices, when the maximum number of registered devices is reached. This action removes the device from the list of devices displayed in the My Devices portal, but the device remains in the Cisco ISE database and continues to be listed in the Endpoints list.

To define the maximum number of personal devices that employees can register using either the BYOD or My Devices portals, choose Administration > Device Portal Management > Settings > Employee Registered Devices.

To permanently delete the device from the Cisco ISE database, choose Work Centers > Network Access > Identities > Endpoints.

Stolen

Enable employees to indicate that their device is stolen. This action updates the device status in the My Devices portal to Stolen, adds the device to the Blocked List endpoint identity group, and removes its certificate.

Device lock

For MDM enrolled devices only.

Enable employees to immediately lock their device remotely from the My Devices portal, in the event it is lost or stolen. This action prevents unauthorized use of the device.

However, the PIN cannot be set in the My Devices portal and should have already been configured by the employee on their mobile device in advance.

Unenroll

For MDM enrolled devices only.

Enable employees to choose this option if they no longer need to use their device at work. This action removes only those applications and settings installed by your company, while retaining other apps and data on the employee's mobile device.

Full wipe

For MDM enrolled devices only.
