    Blocking Ports in HIPS

    epoNovice

      Hey All,

       

      Our security team has asked us to block three individual ports within HIPS.

       

      Is there a chance this could effect other apps that these three ports may use? eg - if an app has a range of ports in use like 21000 - 21800 will blocking one within that range cause issues or do connections just re-rout to another number?

       

      Also when blocking  I'm unsure where to enter the address as a Local Service or Remote service (the alert is for traffic heading out so I would imagine its "remote")

       

      Cheers

          This would depend on the OS and application.  Typically, if an application tries to use a port that you are blocking, the application is going to error out.  If you try again, it might work, if it decides to use a different port number that you are not blocking.

          For outbound traffic, REMOTE SERVICE  would be where the traffic is going to.  For inbound traffic, REMOTE SERVICE would be where the traffic is coming from.
