The Red Hat Enterprise Linux operating system must audit all uses of the renameat syscall.
Overview

|---|---|---|---|---|
| V-72201 | RHEL-07-030890 | SV-86825r5_rule | Medium |
| Description |
|---|
| If the system is not configured to audit certain activities and write them to an audit log, it is more difficult to detect and track system compromises and damages incurred during a system compromise. Satisfies: SRG-OS-000466-GPOS-00210, SRG-OS-000467-GPOS-00210, SRG-OS-000468-GPOS-00212, SRG-OS-000392-GPOS-00172 |

| Verify the operating system generates audit records when successful/unsuccessful attempts to use the "renameat" syscall occur. Check the file system rules in "/etc/audit/audit.rules" with the following commands: # grep -iw renameat /etc/audit/audit.rules -a always,exit -F arch=b32 -S renameat -F auid>=1000 -F auid!=4294967295 -k delete -a always,exit -F arch=b64 -S renameat -F auid>=1000 -F auid!=4294967295 -k delete If both the "b32" and "b64" audit rules are not defined for the "renameat" syscall, this is a finding. |
| Fix Text (F-78555r8_fix) |
|---|
| Configure the operating system to generate audit records when successful/unsuccessful attempts to use the "renameat" syscall occur. Add the following rules in "/etc/audit/rules.d/audit.rules": -a always,exit -F arch=b32 -S renameat -F auid>=1000 -F auid!=4294967295 -k delete -a always,exit -F arch=b64 -S renameat -F auid>=1000 -F auid!=4294967295 -k delete The audit daemon must be restarted for the changes to take effect. |
