In addition to ACL filtering and application inspection, the PIX firewall has attack guards and intrusion detection built in to protect against access and denial-of-service (DoS) attacks. Attack guards help prevent penetration and DoS attacks from taking advantage of basic security threats such as weaknesses and security holes found in commonly used applications. Intrusion detection techniques are used by the PIX firewall to monitor and shun possible attacks by reviewing the IP signatures that pass through the device. This chapter reviews these features within the PIX firewall products.
