//usr/share/doc/audit-2.4.5/capp.rules

##
## This file contains a sample audit configuration.  Combined with the
## system events that are audited by default, this set of rules causes
## audit to generate records for the auditable events specified by the
## Controlled Access Protection Profile (CAPP).
## 
## It should be noted that this set of rules identifies directories by 
## leaving a / at the end of the path.
##
## For audit 2.0.6 and higher
##

## Remove any existing rules
-D

## Increase buffer size to handle the increased number of messages.
## Feel free to increase this if the machine panic's
-b 8192

## Set failure mode to panic
-f 2

##
## FAU_SAR.1, FAU_SAR.2, FMT_MTD.1
## successful and unsuccessful attempts to read information from the
## audit records; all modifications to the audit trail
##
-w /var/log/audit/ -k LOG_audit

## 
## FAU_SEL.1, FMT_MTD.1
## modifications to audit configuration that occur while the audit
## collection functions are operating; all modications to the set of
## audited events
##
-w /etc/audit/ -p wa -k CFG_audit
-w /etc/sysconfig/auditd  -p wa -k CFG_auditd.conf

##
## FDP_ACF.1, FMT_MSA.1, FMT_MTD.1, FMT_REV.1
## all requests to perform an operation on an object covered by the
## SFP; all modifications of the values of security attributes;
## modifications to TSF data; attempts to revoke security attributes
##

## Objects covered by the Security Functional Policy (SFP) are:
## -File system objects (files, directories, special files, extended attributes)
## -IPC objects (SYSV shared memory, message queues, and semaphores)

## Operations on file system objects - by default, only monitor
## files and directories covered by filesystem watches.
