GEN001270
(in versions v1 r19 through v1 r13)
Title
System log files must not have extended ACLs, except as needed to support authorized software. (Cat II impact)
Discussion
If the system log files are not protected, unauthorized users could change the logged data, eliminating its forensic value. Authorized software may be given log file access through the use of extended ACLs when needed and configured to provide the least privileges required.
Check Content
Verify all system log files have no extended ACLs. # ls -lL /var/log /var/log/syslog /var/adm /var/opt If the permissions include a "+" the file has an extended ACL. If an extended ACL exists, verify with the SA if the ACL is required to support authorized software and provides the minimum necessary permissions. If an extended ACL exists providing access beyond the needs of authorized software, this is a finding.
Fix Text
Remove the optional ACL from the file. # chacl -z /var/adm/*
