Set number of records to cause an explicit flush to audit logs

An XCCDF Rule

Description

To configure Audit daemon to issue an explicit flush to disk command after writing records, set freq to in /etc/audit/auditd.conf.

Rationale

If option freq isn't set to , the flush to disk may happen after higher number of records, increasing the danger of audit loss.
