Description:
sudo can use a custom log file
Rationale:
A sudo log file simplifies auditing of sudo commands
Audit:
Verify that sudo has a custom log file configured
Run the following command:
# grep -Ei ^s*Defaultss+([^#]+,s*)?logfile= /etc/sudoers
/etc/sudoers.d/*
Remediation:
edit the file /etc/sudoers or a file in /etc/sudoers.d/ with visudo -f and add the following
line:
Defaults logfile=""
**Example
Defaults logfile="/var/log/sudo.log"
Impact:
editing the sudo configuration incorrectly can cause sudo to stop functioning
Parameter:
[/var/log/sudo.log]
Technical Mechanism:
edit the file /etc/sudoers or a file in /etc/sudoers.d/ with visudo -f and add the following
line:
Defaults logfile=" PATH TO CUSTOM LOG FILE "
**Example
Defaults logfile="/var/log/sudo.log"
