Resolve information before writing to audit logs

An XCCDF Rule

Description

To configure Audit daemon to resolve all uid, gid, syscall, architecture, and socket address information before writing the events to disk, set log_format to ENRICHED in /etc/audit/auditd.conf.

Rationale

If option log_format isn't set to ENRICHED, the audit records will be stored in a format exactly as the kernel sends them.
