Fix Recommendation

Configure the SUSE operating system to generate an audit record for all uses of the "creat", "open", "openat", "open_by_handle_at", "truncate", and "ftruncate" system calls.

Add or update the following rules to "/etc/audit/rules.d/audit.rules":

-a always,exit -F arch=b32 -S creat,open,openat,open_by_handle_at,truncate,ftruncate -F exit=-EPERM -F auid>=1000 -F auid!=4294967295 -k perm_access
-a always,exit -F arch=b64 -S creat,open,openat,open_by_handle_at,truncate,ftruncate -F exit=-EPERM -F auid>=1000 -F auid!=4294967295 -k perm_access

-a always,exit -F arch=b32 -S creat,open,openat,open_by_handle_at,truncate,ftruncate -F exit=-EACCES -F auid>=1000 -F auid!=4294967295 -k perm_access
-a always,exit -F arch=b64 -S creat,open,openat,open_by_handle_at,truncate,ftruncate -F exit=-EACCES -F auid>=1000 -F auid!=4294967295 -k perm_access

To reload the rules file, restart the audit daemon:

> sudo systemctl restart auditd.service

or issue the following command:

> sudo augenrules --load

Check Contents

Verify the SUSE operating system generates an audit record for all uses of the "creat", "open", "openat", "open_by_handle_at", "truncate", and "ftruncate" system calls.

Check that the system calls are being audited by performing the following command:

> sudo auditctl -l | grep 'open\|truncate\|creat'

-a always,exit -F arch=b32 -S creat,open,openat,open_by_handle_at,truncate,ftruncate -F exit=-EPERM -F auid>=1000 -F auid!=-1 -k perm_access
-a always,exit -F arch=b64 -S creat,open,openat,open_by_handle_at,truncate,ftruncate -F exit=-EPERM -F auid>=1000 -F auid!=-1 -k perm_access

-a always,exit -F arch=b32 -S creat,open,openat,open_by_handle_at,truncate,ftruncate -F exit=-EACCES -F auid>=1000 -F auid!=-1 -k perm_access
-a always,exit -F arch=b64 -S creat,open,openat,open_by_handle_at,truncate,ftruncate -F exit=-EACCES -F auid>=1000 -F auid!=-1 -k perm_access

If both the "b32" and "b64" audit rules are not defined for the "creat", "open", "openat", "open_by_handle_at", "truncate", and "ftruncate" syscalls, this is a finding.

If the output does not produce rules containing "-F exit=-EPERM", this is a finding.

If the output does not produce rules containing "-F exit=-EACCES", this is a finding.

Note:
The "-k" allows for specifying an arbitrary identifier. The string following "-k" does not need to match the example output above.

If the output does not produce rules containing "-F exit=-EPERM", this is a finding.

If the output does not produce rules containing "-F exit=-EACCES", this is a finding.
