Procedure

  1. Go to Administration → Notifications → Administrator.
  2. On the Criteria tab:
    1. Go to the C&C Callbacks section.

  3. On the Email tab:
    1. Go to the C&C Callbacks section.
    2. Select Enable notification via email.
    3. Select Send notifications to users with agent tree domain permissions.
      Use Role-based Administration to grant agent tree domain permissions to users. If transmission occurs on any agent belonging to a specific domain, the email are sent to the email addresses of the users with domain permissions. See the following table for examples:

      Agent Tree Domains and Permissions

      Agent Tree Domain
      Roles with Domain Permissions
      User Account with the Role
      Email Address for the User Account
      Domain A
      Administrator (built-in)
      root
      mary@xyz.com
      Role_01
      admin_john
      john@xyz.com
      admin_chris
      chris@xyz.com
      Domain B
      Administrator (built-in)
      root
      mary@xyz.com
      Role_02
      admin_jane
      jane@xyz.com
      If any Security Agent belonging to Domain A detects a C&C callback, the email will be sent to mary@xyz.com, john@xyz.com, and chris@xyz.com.
      If any Security Agent belonging to Domain B detects the C&C callback, the email is sent to mary@xyz.com and jane@xyz.com.
      Note
      Note
