Definition
Security Governance is the framework of rules, practices, and processes that dictate how an organization manages and protects its information assets. It establishes accountability, ensures compliance with regulations and policies, and aligns security strategies with business objectives. This governance is put into practice through defined roles, responsibilities, and decision making structures that guide security operations. It matters because it provides a structured approach to risk management, preventing costly breaches and maintaining stakeholder trust. For instance, a company might implement a security governance policy requiring all new software to undergo a security review before deployment. This differs from security management, which focuses on the operational execution of security controls, whereas governance sets the strategic direction and oversight. Security Governance is a core concept tested on certifications like CompTIA Security+, CySA+, and CISSP.
