Audit Generation | System-Wide / Time-Correlated Audit Trail, v1.0

Defines conformance and assessment criteria for verifying that an information system compiles audit records from into a time-correlated system-wide audit trail.
If an assessment step references organization-defined elements (E.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), corresponding citations/excerpts must be provided to confirm that the organization has established and documented these values and that they apply as referenced in the conformance criteria.

Similarly, if a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]) is specified, evidence must be provided to establish that the option(s) implemented by the organization have been defined and documented.

The assessment step shall not be marked as satisfied without this evidence.

Assessment Step

1
Audit Generation | System-Wide / Time-Correlated Audit Trail (AuditGenerationSystem-WideTime-CorrelatedAuditTrail)
Does the information system compile audit records from [Assignment: organization-defined information system components] into a system-wide (logical or physical) audit trail that is time-correlated to within [Assignment: organization-defined level of tolerance for the relationship between time stamps of individual records in the audit trail]?
Artifact
A1
Provide evidence (e.g. organizational policies, procedures, compliance/assessment reports, etc.) that support the assessor's response to this assessment step.
Parameters
System Wide Audit Trail Typerequired
ENUM : Specify the type of system-wide audit trail.
  • Logical
  • Physical
Timestamp Tolerancerequired
NUMBER : Provide the level of tolerance (in milliseconds) for the relationship between time stamps of individual records in the audit trail.
If conformance criteria reference organization-defined elements (e.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), these values must be defined and documented by the organization.

Similarly, if the criteria specify a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]), the option(s) implemented by the organization must also be defined and documented.
