Checklist Summary:

This document defines a set of benchmarks or standards for securing Cisco PIX firewalls. The benchmark is an industry consensus of current best practices. It lists actions to be taken as well as reasons for those actions. It is intended to provide step-by-step guidance to front line system and network administrators. It may be used manually by itself or in conjunction with automated scoring tools. It contains Level-I and Level-II benchmark settings/actions. Level-I Benchmarks specify the prudent level of minimum due care, and are unlikely to cause an interruption of service to the operating system or the applications that run on it. Level-II Benchmarks provide prudent security beyond the minimum level, and are of the greatest value to system administrators who have sufficient security knowledge to apply them with consideration to the operating systems and applications running in their particular environments.

Checklist Role:

Known Issues:

Sections 2 and 3 contain warnings and explanations of the possible effects of particular settings. Readers should study this information, as well as completing the Audit Checklist in section D, before implementing any of the actions in sections 2 and 3. Many security actions can disable or otherwise interfere with the function or performance of software on your system, particularly applications. Note also that many of the actions in sections 2 and 3 are conditional. They only apply in certain situations.
