To create a new cross-correlation rule

  1. Navigate to Configuration > Threat Intelligence > Cross Correlation, and then click New.
  2. In Data Source Name, select "AlienVault NIDS".

    USM Appliance loads the Event Type list for AlienVault NIDS.

  3. In Reference Data Source Name, select "nessus-detector", which represents the AlienVault Vulnerability Scanner.

    USM Appliance loads the Reference SID Name list for the Vulnerability Scanner.

  4. In Event Type, select "MYSQL client authentication bypass attempt”.

    Note: It takes a while for the list to display because it is long.
