Fix Recommendation

Edit the audit.rules file and add the following line(s) to enable auditing of deletions of files and programs:

-a always,exit -F arch=b64 -S unlink -S unlinkat -S rename -S renameat -F auid=0
-a always,exit -F arch=b64 -S unlink -S unlinkat -S rename -S renameat -F auid>=500 -F auid!=4294967295
-a always,exit -F arch=b32 -S unlink -S unlinkat -S rename -S renameat -F auid=0
-a always,exit -F arch=b32 -S unlink -S unlinkat -S rename -S renameat -F auid>=500 -F auid!=4294967295

Check Contents

To determine if SLES for vRealize is configured to audit calls to the "unlink" system call, run the following command:

# auditctl -l | grep syscall | grep unlink | grep -v unlinkat

If the system is configured to audit this activity, it will return several lines. To determine if the system is configured to audit calls to the "unlinkat" system call, run the following command:

# auditctl -l | grep syscall | grep unlinkat

If the system is configured to audit this activity, it will return several lines. To determine if the system is configured to audit calls to the "rename" system call, run the following command:

# auditctl -l | grep syscall | grep rename | grep -v renameat

If the system is configured to audit this activity, it will return several lines. To determine if the system is configured to audit calls to the "renameat" system call, run the following command:

# auditctl -l | grep syscall | grep renameat

If the system is configured to audit this activity, it will return several lines. If no line is returned, this is a finding.
