Define security requirements: Security requirements must be defined and documented at the beginning of the system development life cycle. Security requirements must include the system's confidentiality, integrity, availability, and the identification and management of system risks.
Conduct a security risk assessment: A security risk assessment must be conducted to identify and assess the risks to the system’s assets, including the data it stores and processes and the people who use it.
Develop a security plan: A security plan must be developed to address the risks identified in the security risk assessment. The security plan must include the application of appropriate security controls, the use of security metrics, and the establishment of security policies and procedures.
Implement security controls: Security controls must be implemented based on the security plan. Security controls must include technical, administrative, and physical controls.
Test security controls: Security controls must be tested to ensure they work effectively and efficiently. Testing must include penetration testing, vulnerability scanning, and security audits.
Monitor and maintain security: The system's security must be monitored and maintained continuously. Security monitoring must include the use of security metrics and the review of security logs.
