The malicious code used in modern attacks has more devastating consequences than the headline-making worms and viruses of the previous era. Many existing protection systems are inadequately prepared to stop new forms of malicious code. Largely signature-based, these legacy security products rely on known attack signatures. When one of these attack signatures is recognized the older security systems sound an alarm and may attempt to block the attack. Signature-based protection can only prevent known attacks however. Hackers recognized the weakness of a signature-based defense and began to develop new zero-day attacks.
