IDS/IPS Signatures Update

Unanswered Question
Apr 21st, 2007


I have one question regarding signatures update, are the Cisco new signatures include the new updates plus the old ones or just the difference between the latest update and the previous one?

If I have an IPS which has never been updated for a year let's say, is it just enough to install the latest signature update and the latest Service pack? Does the service pack include signatures as well when applied?

Please advise!



I have this problem too.

A signature update will contain all Cisco signatures that have been released so far. A service pack will be bundled with a signature update, but not necessarily the latest one. So you should first apply the latest service pack and then apply the latest signature update.

Agreed...and note that some signature updates REQUIRE a certain service pack level to be installed.
