PR.DS-6.1
PR.DS-6.1: The organization shall implement software, firmware, and information integrity checks to detect unauthorized changes to its critical system components during storage, transport, start-up and when determined necessary.
  • State-of-the-practice integrity-checking mechanisms (e.g., parity checks, cyclical redundancy checks, cryptographic hashes) and associated tools can automatically monitor the integrity of information systems and hosted applications.
Documentation Maturity
Not applicable - Not applicable in the selected scope.
Level 1 - Initial - No Process documentation or not formally approved by management.
Level 2 - Repeatable - Formally approved Process documentation exists but not reviewed in the previous 2 years.
Level 3 - Defined - Formally approved Process documentation exists, and exceptions are documented and approved. Documented and approved exceptions < 5% of the time.
Level 4 - Managed - Formally approved Process documentation exists, and exceptions are documented and approved. Documented and approved exceptions < 3% of the time.
Level 5 - Optimizing - Formally approved Process documentation exists, and exceptions are documented and approved. Documented and approved exceptions < 0,5% of the time.
Implementation Maturity
Not applicable - Not applicable in the selected scope.
Level 1 - Initial - Standard process does not exist.
Level 2 - Repeatable - Ad-hoc process exists and is done informally.
Level 3 - Defined - Formal process exists and is implemented. Evidence available for most activities. Less than 10% process exceptions.
Level 4 - Managed - Formal process exists and is implemented. Evidence available for all activities. Detailed metrics of the process are captured and reported. Minimal target for metrics has been established. Less than 5% of process exceptions.
Level 5 - Optimizing - Formal process exists and is implemented. Evidence available for all activities. Detailed metrics of the process are captured and reported. Minimal target for metrics has been established and continually improving. Less than 1% of process exceptions.
