The CNSSI 1253 (Committee on National Security Systems Instruction No. 1253<\/a>) has released (Attachment 2) the Space Platform Overlay <\/strong>as a companion of the NIST SP 800-53 controsl guide.<\/p>\n

Space Overlay<\/strong> is a set of specific guidances and requirements for space. Space Overlay<\/strong> can be used as Security Baseline on some space systems studies.<\/p>\n

But what is a security controls overlay ?<\/h2>\n

My explanation<\/strong> about an overlay is that an overlay is a customisation of security controls applied to a specific domain, in this case to space domain, which uses the NIST 800-53 controls.<\/p>\n

To be more precise<\/strong> \u00a0: “A specification of security controls, control enhancements, supplemental guidance, and other supporting information employed during the tailoring process, that is intended to complement (and further refine) security control baselines. The overlay specification may be more stringent or less stringent than the original security control baseline specification and can be applied to multiple information systems.”<\/em><\/p>\n

Thank’s to NIST<\/strong> for this explanation about security controls overlay<\/strong> (more here<\/a>). Basically, the overlay completes the baseline.<\/p>\n

Florent Rizzo from Cyberinflight<\/strong> written an article with a mindmap of the Space Overlay<\/a> to have a better overview.<\/p>\n

Brandon Bailey from Aerospace<\/strong> also written a White Paper (Translating Security Principles for Space Systems to Existing Standards<\/a>) than mentioned the Space Overlay. The following is an extract from this text (Download Paper<\/a> – PDF – 15 pages – Oct 1, 2020)<\/p>\n
