Create Command and Control Profile

Create a Command and Control (C&C) profile to provide information on C&C servers that have attempted to contact and compromise hosts on your network. A C&C server is a centralized computer that issues commands to botnets of compromised networks of computers and receives reports back from them.

To create a C&C profile:

  1. Click Secure Edge > Security Subscriptions > SecIntel > Profiles.
    The SecIntel Profiles page opens.
  2. Select Create > Command & Control.
    The Create Command & Control Profile page appears.
  3. Complete the configuration according to the guidelines provided in Table 1.
  4. Click OK to save the changes. To discard your changes, click Cancel.

    Once you create the C&C profile, you can associate it with the SecIntel profile groups.
