Learn why anti-evasion is a critical component for your intrusion prevention system. Sophisticated exploits that utilize advanced evasion techniques are all too common.
Intrusion prevention systems (IPS) are designed to prevent known attack traffic patterns from penetrating systems on the network. But there¬¬ís an inherent problem with the technology, since it can block only the attacks it sees and is already familiar with. If malicious code is cleverly disguised, it can slip past IPS defenses, allowing attackers to infiltrate a network. Decoding and normalizing traffic across the network to detect and combat these attacks is critical for your network security plan. See how you can use next-generation firewalls featuring integrated intrusion protection systems to ferret out and block attacks.
Next-generation firewalls rely on deep packet inspection to probe network traffic, scrutinizing packets as they flow through the network. It is imperative that you do everything you can to prevent intrusions. Making the right technology choice is the first - and most important - step.
