The OfficeScan agent can block/log the C&C connection through URL and IP address. The C&C URL is blocked/logged by Web Reputation Service and the C&C IP relies on Suspicious Connection Service. This article shows the detailed configuration for Suspicious Connection Service.

In OfficeScan 11.0, the agent can only log the C&C IP connection and no pop-up alert shows up.

To configure Suspicious Connection Service to block/log the C&C IP address:

  1. On the OSCE web console, go to Agents > Agent Management.
  2. Navigate to Settings and click Additional Service Settings.
  3. Tick Suspicious Connection Service and click Save.
  4. Go to Settings and click Suspicious Connection Settings.
  5. Tick "Detect network connections made to addresses" in the Global C&C IP list. For OfficeScan XG or newer, please select "Log only" or "Block".

    Suspicious Connection Settings

  6. Test the connection to the C&C IP address. In Block mode, the alert will pop up and the log can be found under Suspicious Connection.
