2.2 Security Policies and Procedures

Security policies and procedures form the backbone of an organization's information security strategy. They provide a framework for protecting assets, guiding employee behavior, and ensuring compliance with regulations. From acceptable use to incident response, these guidelines shape how a company approaches cybersecurity.

Implementing effective policies requires careful development, communication, and enforcement. Standard operating procedures translate policies into actionable steps, while security awareness programs educate employees. Regular audits and compliance monitoring help organizations stay on top of their security game and adapt to evolving threats.
