Fix Recommendation

Configure append auditing of the passwd, shadow, group, and gshadow files. Run the dodscript with the following command as root:

# /etc/dodscript.sh
# echo '-w /etc/gshadow -p a -k gshadow' >> /etc/audit/audit.rules

Restart the auditd service.
# service auditd restart

OR

Configure append auditing of the passwd, shadow, group, and gshadow files by running the following commands:

# echo '-w /etc/passwd -p a -k passwd' >> /etc/audit/audit.rules
# echo '-w /etc/shadow -p a -k shadow' >> /etc/audit/audit.rules
# echo '-w /etc/group -p a -k group' >> /etc/audit/audit.rules
# echo '-w /etc/gshadow -p a -k gshadow' >> /etc/audit/audit.rules

Restart the auditd service:
# service auditd restart

Check Contents

Determine if /etc/passwd, /etc/shadow, /etc/group, and /etc/gshadow are audited for appending.

# auditctl -l | egrep '(/etc/passwd|/etc/shadow|/etc/group|/etc/gshadow)' | grep perm=a

If any of these are not listed with a permissions filter of at least "a", this is a finding.

Expected result:
LIST_RULES: exit,always watch=/etc/passwd perm=a key=passwd
LIST_RULES: exit,always watch=/etc/shadow perm=a key=shadow
LIST_RULES: exit,always watch=/etc/group perm=a key=group
LIST_RULES: exit,always watch=/etc/gshadow perm=a key=gshadow
