Configure "execute" auditing of the "usermod" and "groupmod" executables. Add the following to the /etc/audit/audit.rules file:

-w /usr/sbin/usermod -p x -k usermod
-w /usr/sbin/groupmod -p x -k groupmod

Configure "execute" auditing of the "userdel" and "groupdel" executables. Add the following to the /etc/audit/audit.rules file:

-w /usr/sbin/userdel -p x -k userdel
-w /usr/sbin/groupdel -p x -k groupdel

Configure "execute" auditing of the "useradd" and "groupadd" executables. Add the following to audit.rules:

-w /usr/sbin/useradd -p x -k useradd
-w /usr/sbin/groupadd -p x -k groupadd

Configure "execute" auditing of the "passwd" executable. Add the following to the aud.rules:

-w /usr/bin/passwd -p x -k passwd

Configure "write" auditing of the "passwd", "shadow", "group", and "opasswd" files. Add the following to the /etc/audit/audit.rules file:

-w /etc/passwd -p wa -k passwd
-w /etc/shadow -p wa -k shadow
-w /etc/group -p wa -k group
-w /etc/security/opasswd -p wa -k opasswd

Restart the auditd service:

# service auditd restart

Check Contents

Determine if execution of the "usermod" and "groupmod" executable are audited:

# auditctl -l | egrep '(usermod|groupmod)'

If either "usermod" or "groupmod" are not listed with a permissions filter of at least "x", this is a finding.

Determine if execution of the "userdel" and "groupdel" executable are audited:

# auditctl -l | egrep '(userdel|groupdel)'

If either "userdel" or "groupdel" are not listed with a permissions filter of at least "x", this is a finding.

Determine if execution of "useradd" and "groupadd" are audited:

# auditctl -l | egrep '(useradd|groupadd)'

If either "useradd" or "groupadd" are not listed with a permissions filter of at least "x", this is a finding.

Determine if execution of the "passwd" executable is audited:

# auditctl -l | grep “/usr/bin/passwd”

If "/usr/bin/passwd" is not listed with a permissions filter of at least "x", this is a finding.

Determine if /etc/passwd, /etc/shadow, /etc/group, and /etc/security/opasswd are audited for writing:

# auditctl -l | egrep '(/etc/passwd|/etc/shadow|/etc/group|/etc/security/opasswd)'

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