Cisco PIX Security Appliances integrate a broad range of advanced firewall services to protect businesses from the constant barrage of threats on the Internet and in many business network environments. As a secure foundation, Cisco PIX Security Appliances provide rich stateful inspection firewall services, tracking the state of all network communications and preventing unauthorized network access. Building upon those services, Cisco PIX Security Appliances deliver strong application layer security through 30 intelligent, application-aware inspection engines that examine network flows at Layers 4-7. To defend networks from application layer attacks and to give businesses more control over applications and protocols used in their environment, these inspection engines incorporate extensive application and protocol knowledge and employ security enforcement technologies that include protocol anomaly detection, application and protocol state tracking, Network Address Translation (NAT) services, and attack detection and mitigation techniques such as application/protocol command filtering, content verification, and URL deobfuscation. These inspection engines also give businesses control over instant messaging, peer-to-peer file sharing, and tunneling applications, enabling businesses to enforce usage policies and protect network bandwidth for legitimate business applications.
