Abstract

The purpose of the security assessment plan (SAR) is to communicate the results of security assessments of the information technology (IT) infrastructure to include its: people, processes, policies and information systems (NIST, 2010). The SAR is one of the main documents included in the system authorization package, along with the system security plan (SSP) and plan of actions and milestones (POA&Ms). These documents are used to provide the authorizing official (AO) with necessary feedback on the security state and posture of the system to make a risk-based decision if the system should operate or continue operations. The SAR provides the overall state of security of the IT infrastructure detailing the infrastructure’s ability to meet the security objectives: Confidentiality, Integrity, and Availability (CIA) when protecting the data that is transmitted, stored, or processed by and through it. Although the SAR is s document that captures a snapshot in time of the security state of the information system; to support continuous monitoring activities, the SAR is updated whenever subsequent security assessments are performed. To support document revision, the SAR should be annotated with updated versions each time it is changed and these changes should be annotated within the SAR itself. According to NIST (2014), the key elements to an assessment report is outlined in Appendix G (pp G-2); however, for this SAR the following elements will be included: Operating System (OS) Overview, OS Vulnerabilities, Assessment Methodologies, Risk, and Recommendations.
