Participating in the SensorBase Network

IPS 7.0 contains a new security capability, Cisco Global Correlation, which uses the immense security intelligence that we have amassed over the years. At regular intervals, Cisco IPS receives threat updates from the Cisco SensorBase Network, which contain detailed information about known threats on the Internet, including serial attackers, Botnet harvesters, Malware outbreaks, and dark nets. The IPS uses this information to filter out the worst attackers before they have a chance to attack critical assets. It then incorporates the global threat data in to its system to detect and prevent malicious activity even earlier.

If you agree to participate in the SensorBase Network, Cisco will collect aggregated statistics about traffic sent to your IPS. This includes summary data on the Cisco IPS network traffic properties and how this traffic was handled by the Cisco appliances. We do not collect the data content of traffic or other confidential business or personal information. All data is aggregated and sent by secure HTTP to the Cisco SensorBase Network servers in periodic intervals. All data shared with Cisco will be anonymous and treated as strictly confidential.

Table 1-1 shows how we use the data.

Help—Opens the online help in a new window.

The IDM contains hover-over help in addition to online help.

The navigation bar is a docking frame, which you can float or hide if you need more work space. To restore the navigation bar, click View > Navigation.

To configure the sensor, choose Configuration and go through the menus in the left-hand pane. The IDM contains a Startup wizard to aid you in configuring your sensor after you have initialized it. You can change setup settings by using the Startup wizard.

To configure monitoring, click Monitoring and go through the menus in the left-hand pane.

New configurations do not take effect until you click Apply on the pane you are configuring. Click Reset to discard current changes and return settings to their previous state for that pane.

IDM Home Window

The Home pane displays the most important information about a sensor, such as device information, licensing information, sensor health, and interface status.

The IDM continuously sends control transactions to retrieve sensor status information at different snapshots and builds the corresponding graphs in the Home pane.

The Home pane provides information about the state of the sensor according to the gadgets that you choose to display. Each gadget displays the local host time. The gadgets contain the following information:

Sensor Information—Displays specific device information.

Sensor Health—Displays information about the overall health of the sensor and network.

Licensing—Displays information about the status of the license key, signature updates, and signature engine updates. The timestamp on the graph is the sensor local time at each snapshot.

Interface Status—Displays the details about the management and sensing interfaces.

Global Correlation Reports—Displays the alerts and the denied packets resulting from reputation data.

Global Correlation Health—Displays the configuration status of global correlation and Network Participation.

Network Security—Displays alert counts and average and maximum threat and risk ratings. The timestamp on the graph is the sensor local time at each snapshot.

Top Applications—Displays the top ten Layer 4 protocols the sensor has discovered.

CPU, Memory, & Load—Displays the sensor load, CPU, memory, and disk usage for the sensor.

By default, the IDM displays the Sensor Information, Sensor Health, Licensing, Interface Status, Top Applications, and CPU, Memory, & Load gadgets in the Home pane.

To display the available sensor gadgets, click Add Gadgets. You can drag and drop the gadgets on to a tab to display more sensor information. To create another tab in the Home pane to display more information, click Add Dashboard. Use the icons in the top-right corner to collapse, configure the display, or close the gadget.

The IDM constantly retrieves status information to keep the Home pane updated. By default the window is refreshed every 10 seconds. To refresh the pane manually, click File > Refresh.

The IDM is part of the version 7.0 sensor. You must use the setup command to initialize the sensor so that it can communicate with the IDM.

The IDM is a web-based, Java Web Start application that enables you to configure and manage your sensor. The web server for the IDM resides on the sensor. You can access it through Internet Explorer or Firefox web browsers.

To log in to the IDM, follow these steps:


Step 1 Open a web browser and enter the sensor IP address. A Security Alert dialog box appears.

https://sensor_ip_address
 
   

Note The IDM is already installed on the sensor.



Note The default IP address is 192.168.1.2/24,192.168.1.1, which you change to reflect your network environment when you initialize the sensor. When you change the web server port, you must specify the port in the URL address of your browser when you connect to the IDM in the format https://sensor_ip_address:port (for example, https://10.1.9.201:1040).


Step 2 Click Yes to accept the security certificate. The Cisco IPS Device Manager Version 7.0 window appears.

Step 3 To launch the IDM, click Run IDM. The JAVA loading message box appears, and then the Warning - Security dialog box appears.

Step 4 To verify the security certificate, check the Always trust content from this publisher check box, and click Yes. The JAVA Web Start progress dialog box appears, and then the IDM on ip_address dialog box appears.

Step 5 To create a shortcut for the IDM, click Yes. The Cisco IDM Launcher dialog box appears.


Note You must have JRE 1.5 (JAVA 5) installed to create shortcuts for the IDM. If you have JRE 1.6 (JAVA 6) installed, the shortcut is created automatically.


Step 6 To authenticate the IDM, enter your username and password, and click OK. The IDM begins to load. If you change panes from Home to Configuration or Monitoring before the IDM has complete initialization, a Status dialog box appears with the following message:

Please wait while IDM is loading the current configuration from the sensor.
 
   

The main window of the IDM appears.


Note Both the default username and password are cisco. You were prompted to change the password during sensor initialization.



Note If you created a shortcut, you can launch the IDM by double-clicking the IDM shortcut icon. You can also close the The Cisco IPS Device Manager Version 7.0 window. After you launch the IDM, is it not necessary for this window to remain open.



For More Information

For the procedure for using the setup command to initialize the sensor, see Initializing the Sensor.

For more information on how the IDM uses cookies, see The IDM and Cookies.

For more information on how the IDM uses certificates, see IDM and Certificates.

The IDM and Cookies

The IDM uses cookies to track sessions, which provide a consistent view. The IDM uses only session cookies (temporary), not stored cookies. Because the cookies are not stored locally, there is no conflict with your browser cookie policy. The cookies are handled by the IDM Java Start application rather than the browser.

IDM and Certificates


Caution The web browser initially rejects the certificate presented by the IDM because it does not trust the CA.


Note The IDM is enabled by default to use TLS and SSL.We highly recommend that you use TLS and SSL.


Cisco IPS contains a web server that is running the IDM. Management stations connect to this web server. Blocking forwarding sensors also connect to the web server of the master blocking sensor. To provide security, this web server uses an encryption protocol known as TLS, which is closely related to SSL protocol. When you enter a URL into the web browser that starts with https://ip_address, the web browser responds by using either TLS or SSL protocol to negotiate an encrypted session with the host.

The process of negotiating an encrypted session in TLS is called "handshaking," because it involves a number of coordinated exchanges between client and server. The server sends its certificate to the client. The client performs the following three-part test on this certificate:

1. Is the issuer identified in the certificate trusted?

Every web browser ships with a list of trusted third-party CAs. If the issuer identified in the certificate is among the list of CAs trusted by your browser, the first test is passed.

2. Is the date within the range of dates during which the certificate is considered valid?

Each certificate contains a Validity field, which is a pair of dates. If the date falls within this range of dates, the second test is passed.

3. Does the common name of the subject identified in the certificate match the URL hostname?

The URL hostname is compared with the subject common name. If they match, the third test is passed.

When you direct your web browser to connect with the IDM, the certificate that is returned fails because the sensor issues its own certificate (the sensor is its own CA) and the sensor is not already in the list of CAs trusted by your browser.

When you receive an error message from your browser, you have three options:

Disconnect from the site immediately.

Accept the certificate for the remainder of the web browsing session.

Add the issuer identified in the certificate to the list of trusted CAs of the web browser and trust the certificate until it expires.

The most convenient option is to permanently trust the issuer. However, before you add the issuer, use out-of-band methods to examine the fingerprint of the certificate. This prevents you from being victimized by an attacker posing as a sensor. Confirm that the fingerprint of the certificate appearing in your web browser is the same as the one on your sensor.


Caution If you change the organization name or hostname of the sensor, a new certificate is generated the next time the sensor is rebooted. The next time your web browser connects to the IDM, you will receive the manual override dialog boxes. You must perform the certificate fingerprint validation again for Internet Explorer and Firefox.

Validating the CA

Use the following procedure to validate the CA for the web browsers. This example shows how to validate the CA for Internet Explorer, but you can also use it for validating the CA for Firefox.

To use Internet Explorer to validate the certificate fingerprint, follow these steps:


Step 1 Open a web browser and enter the sensor IP address to connect to the IDM. The Security Alert window appears.

https://sensor_ ip_address
 
   

Step 2 Click View Certificate. The Certificate Information window appears.

Step 3 Click the Details tab.

Step 4 Scroll down the list to find Thumbprint and select it. You can see the thumbprint in the text field.


Note Leave the Certificate window open.


Step 5 Connect to the sensor in one of the following ways:

Connect a terminal to the console port of the sensor.

Use a keyboard and monitor directly connected to the sensor.

Telnet to the sensor.

Connect through SSH.

Step 6 Display the TLS fingerprint:

sensor# show tls fingerprint
MD5: C4:BC:F2:92:C2:E2:4D:EB:92:0F:E4:86:53:6A:C6:01
SHA1: 64:9B:AC:DE:21:62:0C:D3:57:2E:9B:E5:3D:04:8F:A7:FD:CD:6F:27
 
   

Step 7 Compare the SHA1 fingerprint with the value displayed in the open Certificate thumbprint text field. You have validated that the certificate that you are about to accept is authentic.


Caution If the fingerprints do not match, you need to determine why. Make sure you are connected to the correct IP address for the sensor. If you are connected to the correct IP address and the fingerprints do not match, this could indicate that your sensor may have been compromised.

Step 8 Click the General tab.

Step 9 Click Install Certificate. The Certificate Import Wizard appears.

Step 10 Click Next. The Certificate Store dialog box appears.

Step 11 Check the Place all certificates in the following store check box, and then click Browse. The Select Certificate Store dialog box appears.

Step 12 Click Trusted Root Certification Authorities, and then click OK.

Step 13 Click Next, and then click Finish. The Security Warning dialog box appears.

Step 14 Click Yes, and then click OK.

Step 15 Click OK to close the Certificate dialog box.

Step 16 Click Yes to open the IDM.


Licensing the Sensor

This section describes how to license the sensor, and contains the following topics:

Understanding Licensing

Licensing Pane Field Definitions

Obtaining and Installing the License Key

Understanding Licensing


Caution You must have a valid sensor license for global correlation features to function. You can still configure and display statistics for the global correlation features, but the global correlation databases are cleared and no updates are attempted. Once you install a valid license, the global correlation features are reactivated.

Although the sensor functions without the license key, you must have a license key to obtain signature updates and use the global correlation features. To obtain a license key, you must have the following:

Cisco Service for IPS service contract—Contact your reseller, Cisco service or product sales to purchase a contract.

Your IPS device serial number—To find the IPS device serial number in the IDM, choose Configuration > Sensor Management > Licensing., or in the CLI use the show version command.

Valid Cisco.com username and password

Trial license keys are also available. If you cannot get your sensor licensed because of problems with your contract, you can obtain a 60-day trial license that supports signature updates that require licensing.

You can obtain a license key from the Cisco.com licensing server, which is then delivered to the sensor. Or, you can update the license key from a license key provided in a local file. Go to http://www.cisco.com/go/license and click IPS Signature Subscription Service to apply for a license key.

You can view the status of the license key in these places:

The IDM Home window Licensing section on the Health tab

The IDM Licensing pane (Configuration > Licensing)

License Notice at CLI login

Whenever you start the IDM or the CLI, you are informed of your license status—whether you have a trial, invalid, or expired license key. With no license key, an invalid license key, or an expired license key, you can continue to use the IDM and the CLI, but you cannot download signature updates.

If you already have a valid license on the sensor, you can click Download on the License pane to download a copy of your license key to the computer that the IDM is running on and save it to a local file. You can then replace a lost or corrupted license, or reinstall your license after you have reimaged the sensor.

For More Information

For more information on global correlation, see Chapter 11 "Configuring Global Correlation."

Service Programs for IPS Products

You must have a Cisco Services for IPS service contract for any IPS product so that you can download a license key and obtain the latest IPS signature updates. If you have a direct relationship with Cisco Systems, contact your account manager or service account manager to purchase the Cisco Services for IPS service contract. If you do not have a direct relationship with Cisco Systems, you can purchase the service account from a one-tier or two-tier partner.

When you purchase the following IPS products you must also purchase a Cisco Services for IPS service contract:

IPS 4240

IPS 4255

IPS 4260

IPS 4270-20

AIM IPS

IDSM2

NME IPS

When you purchase an ASA 5500 series adaptive security appliance product that do not contain IPS, you must purchase a SMARTnet contract.


Note SMARTnet provides operating system updates, access to Cisco.com, access to TAC, and hardware replacement NBD on site.


When you purchase an ASA 5500 series adaptive security appliance product that ships with AIP SSM installed or if you purchase AIP SSM to add to your ASA 5500 series adaptive security appliance product, you must purchase the Cisco Services for IPS service contract.


Note Cisco Services for IPS provides IPS signature updates, operating system updates, access to Cisco.com, access to TAC, and hardware replacement NBD on site.


For example, if you purchase an ASA 5510 and then later want to add IPS and purchase an ASA-SSM-AIP-10-K9, you must now purchase the Cisco Services for IPS service contract. After you have the Cisco Services for IPS service contract, you must also have your product serial number to apply for the license key.


Caution If you ever send your product for RMA, the serial number will change. You must then get a new license key for the new serial number.

For More Information

For information on obtaining and installing the sensor license key, see Obtaining and Installing the License Key.
