AU-16 Cross-organizational Audit Logging

Control

Employ [Assignement: methods] for coordinating [Assignement: audit information] among external organizations when audit information is transmitted across organizational boundaries.

Discussion

When organizations use systems or services of external organizations, the audit logging capability necessitates a coordinated, cross-organization approach. For example, maintaining the identity of individuals who request specific services across organizational boundaries may often be difficult, and doing so may prove to have significant performance and privacy ramifications. Therefore, it is often the case that cross-organizational audit logging simply captures the identity of individuals who issue requests at the initial system, and subsequent systems record that the requests originated from authorized individuals. Organizations consider including processes for coordinating audit information requirements and protection of audit information in information exchange agreements.

Assessment Objective

[Assignement: methods] for coordinating [Assignement: audit information] among external organizations when audit information is transmitted across organizational boundaries are employed.

Assessment Method

Examine

Audit and accountability policy system security plan privacy plan procedures addressing methods for coordinating audit information among external organizations system design documentation system configuration settings and associated documentation system audit records other relevant documents or records

AU-16(01) Identity Preservation

Control

Preserve the identity of individuals in cross-organizational audit trails.

Discussion

Identity preservation is applied when there is a need to be able to trace actions that are performed across organizational boundaries to a specific individual.

Assessment Objective

the identity of individuals in cross-organizational audit trails is preserved.

Assessment Method

Examine

AU-16(02) Sharing of Audit Information

Control

Provide cross-organizational audit information to [Assignement: organizations] based on [Assignement: cross-organizational sharing agreements].

Discussion

Due to the distributed nature of the audit information, cross-organization sharing of audit information may be essential for effective analysis of the auditing being performed. For example, the audit records of one organization may not provide sufficient information to determine the appropriate or inappropriate use of organizational information resources by individuals in other organizations. In some instances, only individuals’ home organizations have the appropriate knowledge to make such determinations, thus requiring the sharing of audit information among organizations.

Assessment Objective

cross-organizational audit information is provided to [Assignement: organizations] based on [Assignement: cross-organizational sharing agreements].

Assessment Method

AU-16(03) Disassociability

Control

Implement [Assignement: measures] to disassociate individuals from audit information transmitted across organizational boundaries.

Discussion

Preserving identities in audit trails could have privacy ramifications, such as enabling the tracking and profiling of individuals, but may not be operationally necessary. These risks could be further amplified when transmitting information across organizational boundaries. Implementing privacy-enhancing cryptographic techniques can disassociate individuals from audit information and reduce privacy risk while maintaining accountability.

Assessment Objective

[Assignement: measures] are implemented to disassociate individuals from audit information transmitted across organizational boundaries.

Assessment Method

Examine

Audit and accountability policy system security plan privacy plan procedures addressing cross-organizational sharing of audit information policy and/or procedures regarding the deidentification of PII system design documentation system configuration settings and associated documentation system audit records other relevant documents or records
