What is the primary purpose of a System Security Plan (SSP) in eMASS?

The primary purpose of a System Security Plan (SSP) in the context of eMASS is to document the system's security requirements, controls, and practices. This comprehensive document serves as a foundational element in the risk management framework, detailing how the system will protect sensitive information and comply with applicable security standards. An SSP includes specific information about the system architecture, the security measures in place, the roles and responsibilities of personnel, and the policies and procedures that govern system operations.

By effectively outlining these components, the SSP ensures that everyone involved in the system—for instance, security personnel, system developers, and management—understands the security posture and requirements of the system. This documentation also plays a critical role in assessing risks and making informed decisions on implementing security controls, thereby supporting the overall mission assurance strategy in eMASS.

Having an SSP is vital for accountability and traceability during security assessments and audits, as it serves as a reference that can be reviewed to ensure compliance with regulatory and organizational directives.
