Check Text ( C-36909r2_chk )
Check the permissions of the syslog configuration file. Depending on what system is used for log processing either /etc/syslog.conf or /etc/rsyslog.conf will be the logging configuration file. # ls -lL /etc/syslog.conf Or: # ls -lL /etc/rsyslog.conf If the permissions include a '+', the file has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.
