Can the IG200/IG2000 protect against “Zero Day” attacks?
Yes. A new attack that has not yet been characterized is called a ‘Zero Day’ attack. Signature based systems generally defend poorly against Zero Day attacks because they have no signature against which to compare the attack pattern. The rate-based IG200/IG2000 will detect the behavior of the attack and take appropriate prevention measures, even for attacks not yet seen or characterized.
