Enter the name of the endpoint profiling policy that you want to create.

Description

Enter the description of the endpoint profiling policy that you want to create.

Policy Enabled

By default, the Policy Enabled check box is checked to associate a matching profiling policy when you profile an endpoint.

When unchecked, the endpoint profiling policy is excluded when you profile an endpoint.

Minimum Certainty Factor

Enter the minimum value that you want to associate with the profiling policy. The default value is 10.

Exception Action

Choose an exception action, which you want to associate with the conditions when defining a rule in the profiling policy.

The default is NONE. The exception actions are defined in the following location: Policy > Policy Elements > Results > Profiling > Exception Actions.

Network Scan (NMAP) Action

Choose a network scan action from the list, which you want to associate with the conditions when defining a rule in the profiling policy, if required.

The default is NONE. The exception actions are defined in the following location: Policy > Policy Elements > Results > Profiling > Network Scan (NMAP) Actions.

Create an Identity Group for the policy

Check one of the following options to create an endpoint identity group:

  • Yes, create matching Identity Group

  • No, use existing Identity Group hierarchy

Yes, create matching Identity Group

Choose this option to use an existing profiling policy.

This option creates a matching identity group for those endpoints and the identity group will be the child of the Profiled endpoint identity group when an endpoint profile matches an existing profiling policy.

For example, the Xerox-Device endpoint identity group is created in the Endpoints Identity Groups page when endpoints discovered on your network match the Xerox-Device profile.

No, use existing Identity Group hierarchy

Check this check box to assign endpoints to the matching parent endpoint identity group using hierarchical construction of profiling policies and identity groups.

This option allows you to make use of the endpoint profiling policies hierarchy to assign endpoints to one of the matching parent endpoint identity groups, as well as to the associated endpoint identity groups to the parent identity group.

For example, endpoints that match an existing profile are grouped under the appropriate parent endpoint identity group. Here, endpoints that match the Unknown profile are grouped under Unknown, and endpoints that match an existing profile are grouped under the Profiled endpoint identity group. For example,

  • If endpoints match the Cisco-IP-Phone profile, then they are grouped under the Cisco-IP-Phone endpoint identity group.

  • If endpoints match the Workstation profile, then they are grouped under the Workstation endpoint identity group.

    The Cisco-IP-Phone and Workstation endpoint identity groups are associated to the Profiled endpoint identity group in the system.

Parent Policy

Choose a parent profiling policy that are defined in the system to which you want to associate the new endpoint profiling policy.

You can choose a parent profiling policy from which you can inherit rules and conditions to its child.

Associated CoA Type

  • No CoA

  • Port Bounce

  • Reauth

  • Global Settings that is applied from the profiler configuration set in Administration > System > Settings > Profiling

Rules

One or more rules that are defined in endpoint profiling policies determine the matching profiling policy for endpoints, which allows you to group endpoints according to their profiles.

One or more profiling conditions from the policy elements library are used in rules for validating endpoint attributes and their values for the overall classification.

Conditions

Click the plus [+] sign to expand the Conditions anchored overlay, and click the minus [-] sign, or click outside the anchored overlay to close it.

Click Select Existing Condition from Library or Create New Condition (Advanced Option) .

Select Existing Condition from Library---You can define an expression by selecting Cisco predefined conditions from the policy elements library.

Allowed Protocols

The following table describes the fields in the Allowed Protocols page, which allows you to configure the protocols to be used during authentication. The navigation path for this page is: Policy > Policy Elements > Results > Authentication > Allowed Protocols.

In the following table, PAC stands for Protected Access Credentials.

Table 21 Allowed Protocols

Fields

Usage Guidelines

Allowed Protocols > Authentication Bypass

Process Host Lookup

Check this check box if you want Cisco ISE to process the Host Lookup request. The Host Lookup request is processed for PAP/CHAP protocol when the RADIUS Service-Type equals 10 (Call-Check) and the username is equal to Calling-Station-ID. The Host Lookup request is processed for EAP-MD5 protocol when the Service-Type equals 1 (Framed) and the username is equal to Calling-Station-ID. Uncheck this check box if you want Cisco ISE to ignore the Host Lookup request and use the original value of the system username attribute for authentication. When unchecked, message processing is done according to the protocol (for example, PAP).

Allowed Protocols > Authentication Protocols

Allow PAP/ASCII

This option enables PAP/ASCII. PAP uses cleartext passwords (that is, unencrypted passwords) and is the least secure authentication protocol.

Allow CHAP

This option enables CHAP authentication. CHAP uses a challenge-response mechanism with password encryption. CHAP does not work with Microsoft Active Directory.

Allow MS-CHAPv1

Check this check box to enable MS-CHAPv1.

Allow MS-CHAPv2

Check this check box to enable MS-CHAPv2.

Allow EAP-MD5

Check this check box to enable EAP-based MD5 password hashed authentication.

Allow EAP-TLS

Check this check box to enable EAP-TLS Authentication protocol and configures EAP-TLS settings. You can specify how Cisco ISE will verify the user identity as presented in the EAP identity response from the end-user client. User identity is verified against information in the certificate that the end-user client presents. This comparison occurs after an EAP-TLS tunnel is established between Cisco ISE and the end-user client.

Note   

EAP-TLS is a certificate-based authentication protocol. EAP-TLS authentication can occur only after you have completed the required steps to configure certificates.

  • Allow authentication of expired certificates to allow certificate renewal in Authorization Policy—Check this check box, if you want to allow users to renew certificates. If you check this check box, ensure that you configure appropriate authorization policy rules to check if the certificate has been renewed before processing the request any further.

Allow LEAP

Check this check box to enable Lightweight Extensible Authentication Protocol (LEAP) authentication.

Allow PEAP

Check this check box to enable PEAP authentication protocol and PEAP settings. The default inner method is MS-CHAPv2.

When you check the Allow PEAP check box, you can configure the following PEAP inner methods:

  • Allow EAP-MS-CHAPv2—Check this check box to use EAP-MS-CHAPv2 as the inner method.

    • Allow Password Change—Check this check box for Cisco ISE to support password changes.

    • Retry Attempts—Specifies how many times Cisco ISE requests user credentials before returning login failure. Valid values are 0 to 3.

  • Allow EAP-GTC—Check this check box to use EAP-GTC as the inner method.

    • Allow Password Change—Check this check box for Cisco ISE to support password changes.

    • Retry Attempts—Specifies how many times Cisco ISE requests user credentials before returning login failure. Valid values are 0 to 3.

  • Allow EAP-TLS—Check this check box to use EAP-TLS as the inner method.

    Check the Allow authentication of expired certificates to allow certificate renewal in Authorization Policy check box, if you want to allow users to renew certificates. If you check this check box, ensure that you configure appropriate authorization policy rules to check if the certificate has been renewed before processing the request any further.

  • Allow PEAPv0 only for legacy clients—Check this check box to allow PEAP supplicants to negotiate using PEAPv0. Some legacy clients do not conform to the PEAPv1 protocol standards. To ensure that such PEAP conversations are not dropped, check this check box.

Allow EAP-FAST

Check this check box to enable EAP-FAST authentication protocol and EAP-FAST settings. The EAP-FAST protocol can support multiple internal protocols on the same server. The default inner method is MS-CHAPv2.

When you check the Allow EAP-FAST check box, you can configure EAP-FAST as the inner method:

  • Allow EAP-MS-CHAPv2

    • Allow Password Change—Check this check box for Cisco ISE to support password changes.

    • Retry Attempts—Specifies how many times Cisco ISE requests user credentials before returning login failure. Valid values are 0-3.

  • Allow EAP-GTC

    Allow Password Change—Check this check box for Cisco ISE to support password changes.

    Retry Attempts—Specifies how many times Cisco ISE requests user credentials before returning login failure. Valid values are 0-3.

  • Use PACs—Choose this option to configure Cisco ISE to provision authorization PACs for EAP-FAST clients. Additional PAC options appear.

  • Don't use PACs—Choose this option to configure Cisco ISE to use EAP-FAST without issuing or accepting any tunnel or machine PACs. All requests for PACs are ignored and Cisco ISE responds with a Success-TLV without a PAC.

    When you choose this option, you can configure Cisco ISE to perform machine authentication.

  • Allow EAP-TLS—Check this check box to use EAP-TLS as the inner method.

    Check the Allow authentication of expired certificates to allow certificate renewal in Authorization Policy check box, if you want to allow users to renew certificates. If you check this check box, ensure that you configure appropriate authorization policy rules to check if the certificate has been renewed before processing the request any further.

  • Enable EAP Chaining—Check this check box to enable EAP chaining.

    EAP chaining allows Cisco ISE to correlate the results of user and machine authentication and apply the appropriate authorization policy using the EAPChainingResult attribute.

    EAP chaining requires a supplicant that supports EAP chaining on the client device. Cisco ISE supports AnyConnect 4.0. Choose the User and Machine Authentication option in the supplicant.

    EAP chaining is available when you choose the EAP-FAST protocol (both in PAC based and PAC less mode).

    For PAC-based authentication, you can use user authorization PAC or machine authorization PAC, or both to skip the inner method.

    For certificate-based authentication, if you enable the Accept Client Certificate for Provisioning option for the EAP-FAST protocol (in the Allowed Protocol service), and if the endpoint (AnyConnect) is configured to send the user certificate inside the tunnel, then during tunnel establishment, ISE authenticates the user using the certificate (the inner method is skipped), and machine authentication is done through the inner method. If these options are not configured, EAP-TLS is used as the inner method for user authentication.

    After you enable EAP chaining, update your authorization policy and add a condition using the NetworkAccess:EapChainingResult attribute and assign appropriate permissions. For example:

    • If EapChainingResult equal User and machine both succeeded - Full access

    • If EapChainingResult equal User passed and machine failed - Restricted access

    • If EapChainingResult equal User failed and machine passed - Restricted access

    • If EapChainingResult equal User and machine both failed - Authentication fails. Cisco ISE does not process the authorization policy and sends a reject access message.

Preferred EAP Protocol

Check this check box to choose your preferred EAP protocols from any of the following options: EAP-FAST, PEAP, LEAP, EAP-TLS, EAP-TTLS, and EAP-MD5. If you do not specify the preferred protocol, EAP-TLS is used by default.

PAC Options

The following table describes the fields after you select Use PACs in the Allowed Protocols Services List page. The navigation path for this page is: Policy > Policy Elements > Results > Authentication > Allowed Protocols.

Table 22 PAC Options

Fields

Usage Guidelines

Use PAC

  • Tunnel PAC Time To Live—The Time to Live (TTL) value restricts the lifetime of the PAC. Specify the lifetime value and units. The default is 90 days. The range is between 1 and 1825 days.

  • Proactive PAC Update When: <n%> of PAC TTL is Left—The Update value ensures that the client has a valid PAC. Cisco ISE initiates an update after the first successful authentication but before the expiration time that is set by the TTL. The update value is a percentage of the remaining time in the TTL. The default is 90%.

  • Allow Anonymous In-band PAC Provisioning—Check this check box for Cisco ISE to establish a secure anonymous TLS handshake with the client and provision it with a PAC by using phase zero of EAP-FAST with EAP-MSCHAPv2. To enable anonymous PAC provisioning, you must choose both of the inner methods, EAP-MSCHAPv2 and EAP-GTC.

  • Allow Authenticated In-band PAC Provisioning—Cisco ISE uses SSL server-side authentication to provision the client with a PAC during phase zero of EAP-FAST. This option is more secure than anonymous provisioning but requires that a server certificate and a trusted root CA be installed on Cisco ISE.

    When you check this option, you can configure Cisco ISE to return an Access-Accept message to the client after successful authenticated PAC provisioning.

    • Server Returns Access Accept After Authenticated Provisioning—Check this check box if you want Cisco ISE to return an access-accept package after authenticated PAC provisioning.

  • Allow Machine Authentication—Check this check box for Cisco ISE to provision an end-user client with a machine PAC and perform machine authentication (for end-user clients who do not have the machine credentials). The machine PAC can be provisioned to the client by request (in-band) or by the administrator (out-of-band). When Cisco ISE receives a valid machine PAC from the end-user client, the machine identity details are extracted from the PAC and verified in the Cisco ISE external identity source. Cisco ISE only supports Active Directory as an external identity source for machine authentication. After these details are correctly verified, no further authentication is performed.

    When you check this option, you can enter a value for the amount of time that a machine PAC is acceptable for use. When Cisco ISE receives an expired machine PAC, it automatically reprovisions the end-user client with a new machine PAC (without waiting for a new machine PAC request from the end-user client).

  • Enable Stateless Session Resume—Check this check box for Cisco ISE to provision authorization PACs for EAP-FAST clients and skip phase two of EAP-FAST (default = enabled).

    Uncheck this check box in the following cases:

    • If you do not want Cisco ISE to provision authorization PACs for EAP-FAST clients

    • To always perform phase two of EAP-FAST

      When you check this option, you can enter the authorization period of the user authorization PAC. After this period, the PAC expires. When Cisco ISE receives an expired authorization PAC, it performs phase two EAP-FAST authentication.

Authorization Profile Settings

The following table describes the fields in the Standard Authorization Profiles page. The navigation path for this page is: Policy > Policy Elements > Results > Authorization > Authorization Profiles.

Table 23 Authorization Profile settings

Fields

Usage Guidelines

Name

Enter a name that identifies the new authorization profile.

Description

Enter a description of the authorization profile.

Access Type

Choose the access type options (ACCESS_ACCEPT or ACCESS_REJECT).

Service Template

Check the check box to enable Cisco ISE to support sessions connecting from SAnet capable devices. ISE implements service templates as authorization profiles that contain a special flag that marks them as “Service Template” compatible. This way, the service template, which is also an authorization profile, can be used in a single policy to support connection with SAnet as well as non-SAnet devices.

Common Tasks

DACL Name

Check the check box and choose existing downloadable ACL options available (for example, Cisco ISE provides two default values in the drop-down list: PERMIT_ALL_TRAFFIC or DENY_ALL_TRAFFIC). The list will include all current DACLs in the local database.

VLAN

Check the check box and enter an attribute value that identifies a virtual LAN (VLAN) ID that you want associated with the new authorization profile you are creating (both integer and string values are supported for the VLAN ID). The format for this entry would be Tunnel-Private-Group-ID:VLANnumber.

Note   

If you do not select a VLAN ID, Cisco ISE uses a default value of VLAN ID = 1. For example, if you only entered 123 as your VLAN number, the Attributes Details pane reflects the following value: Tunnel-Private-Group-ID = 1:123.

Voice Domain Permission

Check the check box to enable the vendor-specific attribute (VSA) of “cisco-av-pair” to be associated with a value of “device-traffic-class=voice”. In a multi-domain authorization mode, if the network switch receives this VSA, the endpoint is placed on to a voice domain after authorization.

Posture Discovery

Check the check box to enable a redirection process used for Posture discovery in Cisco ISE, and enter an ACL on the device that you want to associate with this authorization profile. For example, if the value you entered is acl119, this is reflected in the Attributes Details pane as: cisco-av-pair = url-redirect-acl = acl119. The Attributes Details pane also displays: cisco-av-pair = url-redirect=https://ip:8443/guestportal/gateway?sessionid=
SessionValueIdValue&action=cpp.

Centralized Web Authentication

Check the check box to enable a redirection process that is similar to Posture discovery, but it redirects guest user access requests to the Guest server in Cisco ISE. Enter an ACL on the device that you want to associate with this authorization profile, and select Default or Manual as the redirect option. For example, if the value you entered is acl-999, this is reflected in the Attributes Details pane as: cisco-av-pair = url-redirect-acl = acl-99. The Attributes Details pane also displays: cisco-av-pair = url-redirect=https://ip:8443/guestportal/gateway?sessionid=SessionValueIdValue&action=cwa.

Check the Static IP/Host Name check box to specify an exact IP address or hostname to which you want the user to be redirected to. If this check box is not checked, the user will be redirected to the FQDN of the policy service node that received this request.

Web Redirection (CWA, DRW, MDM, NSP, CPP)

Auto SmartPort

Check the check box to enable Auto SmartPort functionality and enter a corresponding event name value in the text box. This enables the VSA cisco-av-pair with a value for this option as “auto-smart-port=event_name”. Your choice is reflected in the Attributes Details pane.

Filter-ID

Check the check box to enable a RADIUS filter attribute that sends the ACL name that you define in the text box (which is automatically appended with “.in”). Your choice is reflected in the Attributes Details pane.

Reauthentication

Check the check box and enter a value in seconds for maintaining connectivity during reauthentication. You can also choose attribute values from the Timer drop-down list. You choose to maintain connectivity during reauthentication by choosing to use either the default (a value of 0) or RADIUS-Request (a value of 1). Setting this to the RADIUS-Request value maintains connectivity during the reauthentication process.

MACSec Policy

Check the check box to enable the MACSec encryption policy whenever a MACSec-enabled client connects to Cisco ISE, and choose one of the following three options: must-secure, should-secure, or must-not-secure. For example, your choice is reflected in the Attributes Details pane as: cisco-av-pair = linksec-policy=must-secure.

NEAT

Check the check box to enable Network Edge Access Topology (NEAT), a feature that extends identity recognition between networks. Checking this check box displays the following value in the Attributes Details pane: cisco-av-pair = device-traffic-class=switch.

Web Authentication (Local Web Auth)

Check the check box to enable local web authentication for this authorization profile. This value lets the switch recognize authorization for web authentication by Cisco ISE sending a VSA along with a DACL. The VSA is cisco-av-pair = priv-lvl=15 and this is reflected in the Attributes Details pane.

Wireless LAN Controller (WLC)

Check the check box and enter an ACL name in the text field. This value is used in a required Airespace VSA to authorize the addition of a locally defined ACL to a connection on the WLC. For example, if you entered rsa-1188, this would be reflected in the Attributes Details pane as: Airespace-ACL-Name = rsa-1188.

ASA VPN

Check the check box to enable an Adaptive Security Appliances (ASA) VPN group policy. From the Attribute list, choose a value to configure this setting.

Advanced Attributes Settings

  • Activate Patch Management Software GUI—Displays the patch management software user interface. Follow the instructions on this page to change the software settings or initiate software updates.

Click the Products for Selected Vendor drop-down arrow, to view the list of products that the vendor you have specified in the Patch Management Vendor Name supports. For example, if you have selected Vendor A, that has two products, namely Product 1 and Product 2. Product 1 may support the Enable remediation option, whereas Product 2 might not. Or, if Product 1 does not support the Enable and Install missing patches remediation options, then Product 1 is disabled (grayed out). The Products for Selected Vendor table changes according to the selected remediation option.

Fields

Usage Guidelines

Name

Enter a name for the requirement.

Operating Systems

Choose an operating system.

Click plus [+] to associate more than one operating system to the policy.

Click minus [-] to remove the operating system from the policy.

Conditions

Choose a Condition from the list.

You can also create any user defined condition by clicking the Action Icon and associate it with the requirement. You cannot edit the associated parent operating system while creating user defined conditions.

The pr_WSUSRule is a dummy compound condition, which is used in a posture requirement with an associated Windows Server Update Services (WSUS) remediation. The associated WSUS remediation action must be configured to validate Windows updates by using the severity level option. When this requirement fails, the NAC Agent that is installed on the Windows client enforces the WSUS remediation action based on the severity level that you define in the WSUS remediation.

The pr_WSUSRule cannot be viewed in the Compound conditions list page. You can only select the pr_WSUSRule from the Conditions widget.

Remediation Actions

Choose a Remediation from the list.

You can also create a remediation action and associate it with the requirement.

You have a text box for all the remediation types that can be used to communicate to the Agent users. In addition to remediation actions, you can communicate to Agent users about the non compliance of clients with messages.

The Message Text Only option informs Agent users about the noncompliance. It also provides optional instructions to the user to contact the Help desk for more information, or to remediate the client manually. In this scenario, the NAC Agent does not trigger any remediation action.
