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

The primary purpose of a System Security Plan (SSP) is to document the security requirements and controls in place. The SSP serves as a key artifact in the overall risk management framework, detailing how an organization's information systems address security needs. It outlines the security controls that are implemented, the resources allocated to those controls, and how they support compliance with regulatory and organizational policies. This documentation helps ensure that stakeholders, including security personnel and management, have a clear understanding of the system's security posture and the steps taken to protect sensitive data.

Additionally, while outlining network architecture, budgeting for enhancements, and listing software are important aspects of overall security management, they do not encapsulate the comprehensive scope of an SSP. The SSP is more focused on the specific security measures and protocols in place to mitigate risks and protect the system's integrity, confidentiality, and availability.
