Changelog

Updates to the SL5 Standard, newest first. Each entry records a change to a control or to the standard's guidance, with a link to the affected control.

v0.1

Revises two controls in response to external review. PS-3 removes the "Private SF-86" construct and reframes high-tier personnel vetting as an active area of research with two paths: a formal government partnership or the industry-adapted Sensitivity Levels (SenL) Framework. PE-19(1) extends emanations security to adversary-controlled active signals and defines energy-flow policies at Red Zone boundaries.

PS-3Revision

Personnel Screening

Removed the "Private SF-86" construct, which assumed a private vetting process equivalent to a government background investigation that does not yet exist. PS-3 now frames high-tier personnel vetting as an active area of research with two paths: (1) a formal government partnership using existing government clearance authorities, or (2) the Sensitivity Levels (SenL) Framework, an industry-adapted clearance model that labs can deploy without government participation, though it would benefit from government information-sharing.

PE-19(1)Revision

National Emissions Policies and Procedures

Extended emanations security from passive egress prevention to adversary-controlled active signals, covering inbound signal injection used to influence system behavior. Emissions policies now define the permitted energy flows across each Red Zone boundary in both directions.
