Integrating Cisco StealthWatch

Before you configure the integration, you must have the IP Address of the USM AnywhereUSM Appliance Sensor.

Cisco StealthWatch must be configured to forward log data over syslog to USM Anywhere in CEF format.

To configure Cisco StealthWatch to forward log data to USM Anywhere

  1. Select the Domain or any Host Group.
  2. Open the Configuration menu and select Response Management.
  3. From the Actions section in the Response Management menu, select Add and then ArcSight Common Event from the Action Types list.
  4. Provide a name, for example, USM Anywhere Sensor, and add its IP address and its port (514, in most cases).

    Note: Selecting Test sends a test message to the sensor for validation.

  5. Select OK to finish.
  6. From the Rule option in the Response Management menu, select Add.
  7. From the Rule Types list, select Host Alarm.
  8. From the Add Host Alarm Rule option, set a rule name and add the alarm conditions you want forwarded to the rule.

    Note: Pay close attention to set the following "are true" section correctly.

  9. To add a condition (Type, Severity, Source Host, Target Host or Processing Time) select the ellipses (…) button, and then select the desired type(s).

    Note: For a host alarm, best practice is to combine as many types as possible in an Any statement.

    In the current example, an event will be forwarded to ArcSight if Addr_Scan/tcp, Addr_Scan/udp, Bot Infected Host – Successful C&C Activity, or Data Hoarding is detected.

  10. From the Actions dialog, select the USM Anywhere Sensor syslog action for both Active and Inactive conditions.

    If the defined conditions occur, the event will be forwarded to USM Anywhere.
