A simple way to determine if your network IDS or IPS has been tampered with would be to define a series of attacks which you know should be alerted on and then run them from a defined source IP on a regular basis, the information can be filtered out and then you could be alerted if you do not see the results you expect to. We have lots of users who use IDS Informer in this way to ensure that the $$ investment they have made in an IDS or IPS deployment is protected and they are not caught out by a sensor going off line without knowing.

Keep one thing in mind; tripwire does not detect LKM trojans or tampering. There are tools to deal with this; fnord was the first, I believe, but may be too narrowly-designed for mass consumption, if I correctly remember what the creators said at BlackHats '01. Still, they clearly delineate the nature of kernel integrity protection. http://www.synacklabs.net/projects/fnord/

I got to know that tripwire coudl work to find out the integrity , can it be used for integrity of sensors. As what I read from tripwire that Tripwire creates a 'secure' (normally kept on a read-only disk/diskette along w/ the tripwire executable) database of file and directory attributes (including, if you want, complex MD5 and snefru signatures) which then can be used to compare against to see if a file or directory has changed somehow. If a cracker has broken in and replaced your /bin/date file w/ a trojan horse version, tripwire will let you know. do let me know is someone has used some kind of stuff like this for ids sensors to find attack in distributed environment?..
