Summary
This article provides the steps required to create an SMS Responder Action.  In this example, we will be creating an SMS Responder Action to Quarantine a traffic flow and send an E-Mail to the administrator.  This Action will be triggered by a packet hit on filter 0633: FTP: Bad Logon.  This procedure does not utilize the default “IPS Quarantine” action contained in the SMS under the Responder > Actions section.  Instead we are creating a new Responder Action.

What is Quarantine? The Quarantine option enhances your devices to contain or remove offending network users or devices and provides the ability to automate sophisticated responses to security events. By enabling quarantine with a Block action set, you reduce the exposure of your network to internal and external threats.

What is Active Response? Active Response is a policy-based service that reacts to its inputs in order to perform a set of actions. How it reacts and the set of actions taken depends on the Active Response policies configured and enabled in the SMS. A policy can be triggered in several ways: thresholding, manually, web service, or escalation of an IPS Quarantine action. Policies can be configured to include and/or exclude a set of IP addresses.

What are Response Actions? Response Actions are the instructions the system follows when host traffic triggers an Active Response policy. The SMS Active Response system provides pre-defined action types that you can use to create actions that you want to apply in an Active Response policy.

What are Action Sets? Action Sets determine what the IPS does when a packet triggers a filter. An action set can contain more than one action, and can contain more than one type of action. You can globally affect all action sets for pillars in the SMS. When you modify or add an action set, the settings change enterprise-wide for all filters using the action set.

   


The steps required to perform an SMS Responder Action with Quarantine are as follows;

  1. Create a new Action Set to quarantine + Email
  2. Create a Response Action
  3. Create a Active Response Policy
  4. Create a Action Set for “Permit”
  5. Link the Action Set to a filter (0633)
  6. Perform a profile distribution

    • Timeout - If you want to set a timeout option, select the Enable Automatic Timeout check box and enter a time in minutes. Setting an Automatic Timeout here will allow an IP address to have its traffic automatically unblocked after the specified period of time. Otherwise the quarantined host will remain blocked indefinitely or until it is cleared manually.
  5. Click Next or select the Inclusions and Exclusions tab. In the Inclusions and Exclusions screen enter the required information:
    • Allow Active Response, specify the hosts or networks eligible for this Active Response Action or select Any IP address.

      • Send SNMP Trap Notification - unchecked
