Signatures, Heuristics and Behavior Blocking

Sarah Merrion - Symantec

Feb 18, 2004

Abstract

Blended threats, which use combinations of malicious code to transmit and
spread attacks, are increasing and are among the most important trends to
watch and guard against in 2004. By using multiple techniques, blended
threats can spread to large numbers of hosts, causing rapid and widespread
damage, as evidenced by the examples seen in August, 2003. Today's
protection to these threats rely heavily on reactive technologies rather an
a proactive mitigation approach. This presentation will look at three
technologies for detecting malicious code: signature based detection
(fingerprinting), heuristics, and behavior blocking as solutions to address
these threats. We'll discuss where technology is headed and how to optimize
protection for the fast spreading threats of the future.
