Fix Recommendation

Navigate to and open:

/etc/audit/rules.d/audit.STIG.rules

Add the following lines:

-a always,exit -F arch=b64 -S chmod,fchmod,chown,fchown,fchownat,fchmodat -F auid>=1000 -F auid!=4294967295 -F key=perm_mod
-a always,exit -F arch=b64 -S chmod,fchmod,chown,fchown,lchown,setxattr,lsetxattr,fsetxattr,removexattr,lremovexattr,fremovexattr,fchownat,fchmodat -F key=perm_mod
-a always,exit -F arch=b32 -S chmod,fchmod,fchown,chown,fchownat,fchmodat -F auid>=1000 -F auid!=4294967295 -F key=perm_mod
-a always,exit -F arch=b32 -S chmod,lchown,fchmod,fchown,chown,setxattr,lsetxattr,fsetxattr,removexattr,lremovexattr,fremovexattr,fchownat,fchmodat -F key=perm_mod

At the command line, run the following command to load the new audit rules:

# /sbin/augenrules --load

Note: A new "audit.STIG.rules" file is provided for placement in "/etc/audit/rules.d" that contains all rules needed for auditd.

Note: An older "audit.STIG.rules" may exist if the file exists and references older "GEN" SRG IDs. This file can be removed and replaced as necessary with an updated one.

Check Contents

At the command line, run the following command:

# auditctl -l | grep chmod

Expected result:

-a always,exit -F arch=b64 -S chmod,fchmod,chown,fchown,fchownat,fchmodat -F auid>=1000 -F auid!=4294967295 -F key=perm_mod

-a always,exit -F arch=b64 -S chmod,fchmod,chown,fchown,lchown,setxattr,lsetxattr,fsetxattr,removexattr,lremovexattr,fremovexattr,fchownat,fchmodat -F key=perm_mod

-a always,exit -F arch=b32 -S chmod,fchmod,fchown,chown,fchownat,fchmodat -F auid>=1000 -F auid!=4294967295 -F key=perm_mod

-a always,exit -F arch=b32 -S chmod,lchown,fchmod,fchown,chown,setxattr,lsetxattr,fsetxattr,removexattr,lremovexattr,fremovexattr,fchownat,fchmodat -F key=perm_mod

If the output does not match the expected result, this is a finding.

Note: The auid!= parameter may display as 4294967295 or -1, which are equivalent.

Note: This check depends on the auditd service to be in a running state for accurate results. The auditd service is enabled in control PHTN-30-000013.
