RELEVANT INFORMATION:
The primary objective of DODA Shield is to facilitate the development of a comprehensive System Security Plan (SSP) and Plan of Action and Milestones (POA&M) for organizations. To achieve this, we have carefully curated and rearranged the controls in a manner that optimizes their implementation within a company’s context. Each control is accompanied by a link to detailed information, as well as a sample SSP and POA&M. These resources are intended to serve as valuable starting points, enabling organizations to enhance their security posture effectively and efficiently.
