On Access, most of the rootkits on the systems have hidden themselves from AV, therefore rendering its "On Access" detection useless. Its not whether AV is good or not, its just a race not worth running anymore trying to fight common threat vectors with signature techniques. Been using CSA here for about 5+ yrs and its cut down the Malware/Spyware drastically, due to controlling code execution period, its hooked into the Kernel so it can't be bypassed, and has saved the bacon more than a few times.
Too bad Cisco royally screwed up CSA 6.0 and is discontinuing V5.0 which leaves folks in a pickle and looking for other solutions and application whitelisting seems to be the best of the choices atm. Its not fool-proof, but again its controlling execution, and you have a method of vetting what software is good and what is bad in your environments, which is a ton better than just putting AV on the system and calling it a day...

How is whitelisting or blacklisting going to help? Answer: it's not. The problem is thread pre-emption and storing values in user-mode memory space where it can be altered (assuming you can get the timing right). But, if your AV was any good, it would detect the problem "on access" Cheers Ken -----Original Message----- From: Ziots, Edward [mailto:[email protected]] Sent: Tuesday, 11 May 2010 9:16 PM To: NT System Admin Issues Subject: RE: Life just keeps getting better.... You can also read the blurb on San's ISC page also, some vendors say its important, and of course Mcafee discredits it, not that suprises me. But it is an attack vector to consider. Controling the execution of code on your system is the difference between keeping your systems clean and getting 0wned. Whether you look at HIPS/Whitelisting/Blacklisting, otherwise, you are going to have to have more on your systems than just AV to combat todays threat landscape.
