[RFC] audit.spec: create audit group for log read access

Hi, 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 modification. Excerpt from SUSE's CC certification (RH's seems to match): ---- begin ---- 6.2.1.4 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 ok. Cheers, Enzo
