Title: Keep Attackers At Bay

The new and rapidly evolving capabilities of worms and malicious software threaten to overmatch the capabilities of traditional intrusion-detection systems. Some businesses are turning to behavioral-analysis software to bolster their security systems. This software provides advanced protection against unknown exploits, asset protection, and additional layers of defense for crucial servers and desktops. Cisco Systems, Mcafee, and Sana Security are now offering host-based behavioral monitoring programs that fit between the kernel space and the operating system, monitoring system calls and analyzing them in terms of a set of rules and a list of known behaviors. Any system call that arouses suspicion can be blocked without the necessity of developing attack signatures. McAfee's Entercept employs an Active Malware Defense Technology to shut down applications that give strong signals that they may be malware. Cisco requires administrators to create rules for its agent, as do Entercept and Primary Response; the actions taken are based on information given to the programs. Determina Inc's The Memory Firewall, on the other hand, first blocks malicious code based on its own criteria, then moves it to a secure cache. Still, Memory Firewall protects only against memory-based attacks, without the complete range of protection against malware and other attacks.
