Intrusion prevention signatures not updating

Rated 3.87/5 based on 887 customer reviews

The signature database is one of the major components of the intrusion prevention system (IPS).It contains definitions of different objects, such as attack objects, application signature objects, and service objects, that are used in defining IDP policy rules.The IPS signature database is stored on the IPS-enabled device and contains definitions of predefined attack objects and groups.These attack objects and groups are designed to detect known attack patterns and protocol anomalies within the network traffic.Sep 4 old-community jobsengine[7669]: FETCHSNORTRULES-Etag not changed.
