3.3 AUDIT AND ACCOUNTABILITY

3.3.9 Limit management of audit logging functionality to a subset of privileged users | NIST 800-171 control 3.3.9 safeguards audit logs by limiting control to a select few privileged users. This boosts accountability as it restricts who can tamper with logs, making investigations easier. It improves security by preventing privileged users from hiding their actions. To implement this, only authorized personnel get permissions to manage audit logging, ensuring a clear audit trail.

3.3.9 Limit management of audit logging functionality to a subset of privileged users

NIST 800-171 control 3.3.9 safeguards audit logs by limiting control to a select few privileged users. This boosts accountability as it restricts who can tamper with logs, making investigations easier. It improves security by preventing privileged users from hiding their actions. To implement this, only authorized personnel get permissions to manage audit logging, ensuring a clear audit trail.



Individuals with privileged access to a system and who are also the subject of an audit by that system, may affect the reliability of audit information by inhibiting audit logging activities or modifying audit records. This requirement specifies that privileged access be further defined between audit-related privileges and other privileges, thus limiting the users with audit-related privileges.

Benefits:

Reliable Evidence: By restricting who can manage audit logs, you prevent privileged users from tampering with them. This ensures a trustworthy record of system activity for security investigations and compliance audits.

Reduced Risk of Insider Threats: Limiting access to log management minimizes the chance of insiders disabling logging or modifying records to hide malicious actions.

Improved Accountability: Clear separation of duties makes it easier to track who made changes to audit configurations, facilitating better accountability within your organization.

Accountability:

Senior Management: Set the tone by approving policies and procedures for handling audit logging. This ensures a clear direction and emphasizes the importance of audit log integrity for the organization.



IT Security Team: Take the lead on implementing technical controls. This involves creating processes to restrict access to audit log management functions and monitoring those logs for suspicious activity. They are the technical experts responsible for the system's security posture.

System Owners: Are accountable for enforcing the controls on their specific systems. This might involve assigning permissions within the system itself to limit who can change logging configurations.

Individual Users: Everyone must comply with the established policies and procedures. This means not attempting to manipulate audit logs or exceeding their authorized access level.

Implementation:

Identify Authorized Users: Determine roles (security analysts, auditors) who legitimately need access to manage logs. Don't grant these privileges to general system administrators.

Implement Access Controls: Use your system's access control mechanisms to create dedicated user groups or roles with specific permissions for audit log management.

Document and Monitor: Clearly document who has access and regularly monitor their activity for suspicious changes. Consider additional security measures like multi-factor authentication for added protection.
