Appendix B. ASA/PIX Version 7 Advanced Features

ASA/PIX version 7 is a major release of what was previously known as the PIX operating system. ASA is a new class of devices that now share the operating system with the PIX Security Appliance.

However, most features are to help to increase network security and protect network assets.

To be consistent with the format of this book, the features are listed by how they fit into the defense in depth layers:

• Authentication enhancements

• Perimeter protection enhancements

• Intrusion prevention enhancements

• Security management

• VPN enhancements

• General security appliance enhancements
