The operating system must protect the audit records resulting from non-local accesses to privileged accounts and the execution of privileged functions.

An XCCDF Rule

Description

<VulnDiscussion>Protection of audit records and audit data is of critical importance. Care must be taken to ensure privileged users cannot circumvent audit protections put in place. Auditing might not be reliable when performed by an operating system which the user being audited has privileged access to. The privileged user could inhibit auditing or directly modify audit records. To prevent this from occurring, privileged access shall be further defined between audit-related privileges and other privileges, thus limiting the users with audit-related privileges.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The root role is required.

Determine the location of the local audit trail files.

# pfexec auditconfig -getplugin audit_binfile
Plugin: audit_binfile (active)Attributes: p_dir=/var/audit;p_fsize=4M;p_minfree=1

In this example, the audit files can be found in /var/audit.

Change the permissions on the audit trail files and the audit directory.

# chmod 640 /var/share/audit/*

# chmod 750 /var/share/audit

Note:  The default Solaris 11 location for /var/audit is a link to /var/share/audit.
