RE: Definition of Zero Day Protection

["Carey, Steve T GARRISON" <steven-carey () us army mil>]

Would say they are 'misguided', they believe it.  But from the different IDS and IPS systems I have tested and used, 
the IPS CAN stop attacks, however, if someone in your organization starts using a new software, it may get stopped by 
the IPS.  Also, if the Zero Day Exploit is on the encrypted side, like ssl, then no it wouldn't stop it.  

There is some new technology being worked concerning Kernel Protection that comes close, but still is being worked.

The biggest problem with Zero Day Protection is encrypted programs.  Host based programs can work, but still believe 
that as of today it is still going to take a human to ensure Zero Day Protection (provided they have the necessary 
tools to do it with).

Marketing ploy??  You mean marketing people don't state the truth about
Zero Day Protection and how it works ??

My own personal opinion, based on 7 years of experience in intrusion
detection, is that it is a marketing ploy.  Only way to ensure Zero Day
Protection is to use a 'suite' of IDS tools and have an analyst looking
at those logs 24/7 to find the Zero Day Exploit.  

Vendors can state they prevent Zero Day Exploits but to do that you can
also stop legitimate traffic.  Maybe sometime in the future that can
happen, but not today.
