Security policies and procedures are the backbone of network security and forensics. They establish guidelines, standards, and protocols to protect an organization's assets, data, and systems from threats. By defining acceptable use, access control, incident response, and more, these policies create a framework for implementing security controls.

Effective policies help prevent breaches, detect incidents, and enable timely responses to threats. When coupled with detailed procedures, they provide practical guidance for employees to follow security best practices in their daily work. Regular reviews and updates ensure policies remain relevant as threats and technologies evolve.
