Protection Of Audit Information | Audit Backup On Separate Physical Systems / Components, v1.0

Defines conformance and assessment criteria for verifying that an information system backs up audit records at an organization-defined frequency onto a physically different system or system component than the system or component being audited.
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
Protection Of Audit Information | Audit Backup On Separate Physical Systems / Components (ProtectionOfAuditInformationAuditBackupOnSeparatePhysicalSystemsComponents)
Does the information system backs up audit records at an organization-defined frequency onto a physically different system or system component than the system or component being audited?
Artifact
A1
Provide evidence (e.g. organizational policies, procedures, compliance/assessment reports, etc.) that support the assessor's response to this assessment step.
Parameter
Audit Record Backup Frequencyrequired
NUMBER : Provide the audit record backup frequency in hours.
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.
