Assessment Title

Rule Text

The audit system must be configured to audit all attempts to alter system time through stime.

Description

Discussion Text

Arbitrary changes to the system time can be used to obfuscate nefarious activities in log files, as well as to confuse network services that are highly dependent upon an accurate system time (such as sshd). All changes to the system time should be audited.

Assessment Procedure

Check Text

If the system is 64-bit only, this is not applicable.

To determine if the system is configured to audit calls to the "stime" system call, run the following command:

$ sudo grep -w "stime" /etc/audit/audit.rules
-a always,exit -F arch=b32 -S stime -k audit_time_rules

If the system is not configured to audit the "stime" system call, this is a finding.

Implementation Procedure

Fix Text

On a 32-bit system, add the following to "/etc/audit/audit.rules": 

# audit_time_rules
-a always,exit -F arch=b32 -S stime -k audit_time_rules

Note: On a 64-bit system, it is not necessary to define a rule for "stime".
