AU-16 CROSS-ORGANIZATIONAL AUDITING

Control: The organization employs [Assignment: organization-defined methods] for coordinating [Assignment: organization-defined audit information] among external organizations when audit information is transmitted across organizational boundaries.

Supplemental Guidance: When organizations use information systems and/or services of external organizations, the auditing capability necessitates a coordinated approach across organizations. For example, maintaining the identity of individuals that requested particular services across organizational boundaries may often be very difficult, and doing so may prove to have significant performance ramifications. Therefore, it is often the case that cross-organizational auditing (e.g., the type of auditing capability provided by service-oriented architectures) simply captures the identity of individuals issuing requests at the initial information system, and subsequent systems record that the requests emanated from authorized individuals. Related control: AU-6.

Control Enhancements:

cross-organizational auditing | identity preservation

The organization requires that the identity of individuals be preserved in cross-organizational audit trails.

Supplemental Guidance: This control enhancement applies when there is a need to be able to trace actions that are performed across organizational boundaries to a specific individual.

cross-organizational auditing | sharing of audit information

The organization provides cross-organizational audit information to [Assignment: organization-defined organizations] based on [Assignment: organization-defined cross-organizational sharing agreements].

Supplemental Guidance: Because of 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 the home organizations of individuals have the appropriate knowledge to make such determinations, thus requiring the sharing of audit information among organizations.

FAMILY: SECURITY ASSESSMENT AND AUTHORIZATION

CA-1 SECURITY ASSESSMENT AND AUTHORIZATION POLICY AND PROCEDURES

Control: The organization:

Develops, documents, and disseminates to [Assignment: organization-defined personnel or roles]:

A security assessment and authorization policy that addresses purpose, scope, roles, responsibilities, management commitment, coordination among organizational entities, and compliance; and
Procedures to facilitate the implementation of the security assessment and authorization policy and associated security assessment and authorization controls; and

Reviews and updates the current:

Security assessment and authorization policy [Assignment: organization-defined frequency]; and
Security assessment and authorization procedures [Assignment: organization-defined frequency].

Supplemental Guidance: This control addresses the establishment of policy and procedures for the effective implementation of selected security controls and control enhancements in the CA family. Policy and procedures reflect applicable federal laws, Executive Orders, directives, regulations, policies, standards, and guidance. Security program policies and procedures at the organization level may make the need for system-specific policies and procedures unnecessary. The policy can be included as part of the general information security policy for organizations or conversely, can be represented by multiple policies reflecting the complex nature of certain organizations. The procedures can be established for the security program in general and for particular information systems, if needed. The organizational risk management strategy is a key factor in establishing policy and procedures. Related control: PM-9.

Control Enhancements: None.
