Cybersecurity Case

Structured argument with evidence that an item's cybersecurity goals are met.

The cybersecurity case is the assurance argument that ties claims to evidence. It is updated through development, used as the basis for cybersecurity assessment, and referenced in the release-for-post-development decision. Without a clean case, an audit cannot find the path from a threat to its mitigation.
