Information security governance is the system by which an organisation's security activities are directed and controlled. It makes sure security supports business objectives, risks are managed to an acceptable level and resources are used responsibly.
Typical elements:
- Clear roles and accountability (board, executive sponsor, CISO, risk owners).
- Approved strategy, policies and risk appetite.
- Committees and reporting lines (e.g. a security or risk steering committee).
- Performance measurement and independent assurance.
Frameworks such as COBIT 2019, ISO/IEC 27014 and the Govern function of NIST CSF 2.0 describe governance practices.
A CISO presents a quarterly cyber dashboard to the executive committee, which approves the security strategy and budget and decides which top risks to fund. That decision-making and oversight loop is security governance.
