RE: Antivirus- A Corrective Control?

[Curtis 4syth <curtis () 4syth net>]

I don't think that's exactly the case.  AV systems can prevent SOME things before it "knows about it" via Signature 
Update or whatever.

The biggest is Heuristic Scanning; it's looking for uncommon instructions, encryption loops that shouldn't be there, 
things like that.  They then follow rules or set weights (like MX records) to the Application. If a rule is triggered, 
or the weight gets to high, the AV gets flagged.  This can easily prevent new malware, or a mutation of a current piece 
of code.

I do not think so.  An AV can only play catch-up with the known
threats and not prevent something it does not know about.
