self authentication for sensors in ids ?

["Gaurav_Jindal" <gaurav_jindal () da-iict org>]

Hi,

I would like to know specific for snort , prelude ids is

(1) Are these ids uses some autentication scheme to check for integrity 
of sensor code deployed on the application, host or machine
(2) does self authentication schemes like md5 algorithm, or these 
algorithms are used for integity of sensor code.
(3) What are the probable chances for failure of the above conditions 
putting sensors or IDS in hands on attacker?
(4) If the source code for snort or prelude have these features what 
part of code should i follow specifically to have my answers
(5) Alos please suggest any future directions.

Thanking you,
With Regards,
Gaurav Jindal
