securitymanagement

Security management is the set of policies, processes, and controls used to protect an organization's people, assets, information, and operations from threats. It seeks to manage risk by balancing protection with business needs and by integrating physical and information security under a coherent governance structure.

Core components include governance and policy development, risk assessment and risk treatment, access control and identity management, security architecture and operations, incident response and disaster recovery, physical security, and regulatory compliance. These elements work together to prevent, detect, respond to, and recover from security incidents while supporting business continuity.

The security management lifecycle typically follows a cycle of assessment, design and implementation, operation, monitoring, and continuous improvement. Organizations measure performance with indicators such as incident frequency, mean time to detect and respond, control effectiveness, audit findings, and compliance status.

Common frameworks and standards guide practice, including ISO/IEC 27001, the NIST Cybersecurity Framework, NIST SP 800-53, and CIS Controls. Roles often include a chief information security officer or security manager, security architects, incident responders, auditors, and compliance officers. Security management interfaces with enterprise risk management, governance, business continuity planning, and regulatory obligations to align protection with strategic objectives.
