  • 1.  IPS is blocking Traffic from internal vulnerability Check Server

    Posted Feb 04, 2013 08:11 AM

    Hi All,

    Good Day,

    We are using Sep 12.1 RU 1 MP 1 and doesn’t using SEP firewall module on Machines and some of the Machines IPS is blocking an application and logging an event with Severity: Critical, while we are trying to run our vulnerability Check from VA application?

    We need to exclude all traffic from VA server, and how we can achieve this?

    A Sample Risk Log has been attached

    You can add the IP of the VA server in the exlcuded hosts file in the IPS policy. See here

    Hi!

    In my opinion it is applicabale in your case. Or You can use application learning and you should add it to exclusion list.

    Yes it still applies in your case. Firewall and IPS are apart of Network Threat Protection but are separate components. You can use both or only one.
