I am looking to see if CSCsa166823 was included in 4.1(3)s91 service pack???

I'm looking to find out why some 600+ signatures out of 1100+ signatures are disabled by default? Is there any documentation on the process Cisco uses for determining when/if a signature is disabled??

Is ther somewhere I can download older signature releases? I am looking for IDS-sig-4.1-3-S71, and the latest I could find is S76.

What is the recommended way to check that a sensor isactually functioning properly? By this I mean that if a sensor is up, and you are not receiving any events in security monitor, and want to see if it is just low activity vs. a problem on the sens...

Is there a way to find out when particular sigid's were disabled, ie. what signature update?? The NSDB has a field for when it was released, but what about when they are retired/disabled??
