Summary

A network security policy is a plan that provides procedures for managing a computing environment. In particular, it gives the system administrator operational guidelines for the environment, such as rules for user account management, system installation procedures, software update processes, the use of security tools, procedures for handling unauthorized access, and so on. The effect of properly using the security policy is a consistent and predictable environment with the added benefit of making anomalies, such as unauthorized access or break-ins, easier to detect.
