  1. Security Requirements

Completeness and Consistency

Ideally, requirements should be both complete and consistent:

  • Complete - They should include descriptions of all facilities required.

  • Consistent - There should be no conflicts or contradictions in the descriptions of the system facilities.

In reality, it is very difficult/impossible to produce a complete and consistent requirements document
