    How to match two Destination IPs from same subnet

    mcv99 cv

      Hi

       

      I want to create a correlation rule that matches true if it sees two IPs from the same /24 subnet.

       

      If I have two events with the same signature ID, one from IP 10.2.3.4 and IP 10.2.3.5, I want them to match true to trigger an alarm.

       

      I can't see a method to tell siem that I want to match IPs from a same subnet range, and remain as abstract as possible, like x.x.x.x/24

       

      Can anyone tell me how to do this?

       

      Thank you very much
