Most security testing software is designed to test various aspects of system security. Some programs are comprehensive, and others

The primary benefit of these tools is that they are convenient and automated, and can be run regularly with little effort. The chief

detecting newly discovered security problems, unless you modify or update them. Security testing must be viewed as a supplement to
proper auditing practices, not a replacement.
The three major security tool categories are shown in the table below.
The only way to ensure continued security is by applying sound principles, modified by experimentation and experience. New networking
technologies appear quickly, so it is incumbent for network administrators to keep abreast of the latest developments.
