The SSAA (System Security Authorization Agreement) is a document that provides a detailed description of the security controls and safeguards implemented to secure a system or application. It is a critical document that serves as the basis for authorizing the system to operate in a specific environment.
The SSAA maintenance process involves the continuous monitoring of the security controls and safeguards to ensure that they remain effective over time. The maintenance process also includes updating the SSAA to reflect any changes made to the system, such as new security controls or changes to the system's environment.
The phases of the security assessment and authorization (SA&A) process are defined in NIST SP 800-37, which is a guide for implementing a risk management framework for information systems. The four phases of the SA&A process are:
Initiation: In this phase, the system owner identifies the need for a new system or major changes to an existing system that require a reassessment of its security controls.
Security categorization: In this phase, the system is categorized based on its security impact level, which determines the minimum security controls required to protect the system.
Security control selection, implementation, and assessment: In this phase, the security controls are selected, implemented, and assessed to ensure that they are effective in mitigating the identified risks.
Authorization: In this phase, the authorizing official reviews the results of the security assessment and authorizes the system to operate based on the level of risk it poses to the organization.
To answer the question, the SSAA maintenance takes place in Phase 4, which is the authorization phase. During this phase, the system is authorized to operate, and the SSAA is reviewed and updated to reflect any changes made to the system. The SSAA must be maintained throughout the system's lifecycle to ensure that it remains current and accurate, and to support ongoing security monitoring and risk management activities.
