🔒 Security Management
Security Management within ITIL 4 ensures that organisational information assets are protected against threats through risk-based controls, governance policies, and continuous monitoring. It aligns with ISO/IEC 27001, NIST CSF, and CIS Controls to deliver a defence-in-depth posture.
Why Security Management Matters
- Protects confidentiality, integrity, and availability (CIA triad) of services
- Reduces risk of data breaches, ransomware, and insider threats
- Supports regulatory compliance (GDPR, NIS2, SOC 2, ISO 27001)
- Integrates with Change Management to prevent security regressions
- Enables zero-trust architecture and least-privilege access models
