We (SUSE) would like to introduce an "audit" group for log read access.

This would be handled only by patching the .spec file to create the
group and modify the permissions of the default log dir/file to:

drwxr-x--- 1 root audit     322 25. Okt 21:06 /var/log/audit/
-rw-r----- 1 root audit 1815972 26. Okt 22:23 /var/log/audit/audit.log

No source code modifications are required, as log_group_parser() should
handle invalid entries.

If an enforcement or warning is required for when log_group is not
using the default "audit" group, it should be easy to do as well.

For those wondering, Common Criteria seems to be fine with this

Excerpt from SUSE's CC certification (RH's seems to match):

---- begin ---- Restricted audit review (FAU_SAR.2)

FAU_SAR.2.1	The TSF shall prohibit all users read access to the audit records, except those
		users that have been granted explicit read-access.

Application Note: The protection of the audit records is based on the Unix permission bit
settings defined by FDP_ACC.1(PSO) supported by FDP_ACF.1(PSO).
---- end ----

Please let me know of your concerns, if any.

I have a working patch that I can submit right away in case this gets an
