Ensure sudo log file exists

高レベル 1自動freebsd

説明

The Defaults logfile entry sets the path to the sudo log file. Setting a path turns on logging to a file; negating this option turns it off. By default, sudo logs via syslog. Defining a dedicated log file for sudo simplifies auditing of sudo commands and creation of auditd rules for sudo. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.

修正方法

修正方法: ガイダンスまたは IaC パッチ

Edit the file /usr/local/etc/sudoers or a file in /usr/local/etc/sudoers.d/ with visudo or visudo -f <PATH TO FILE> and add the following line: Defaults logfile="<PATH TO CUSTOM LOG FILE>" Example Defaults logfile="/var/log/sudo.log" Note: sudo will read each file in /usr/local/etc/sudoers.d, skipping file names that end in ~ or contain a . character to avoid causing problems with the package manager or editor temporary/backup files. Files are parsed in sorted lexical order. That is, /usr/local/etc/sudoers.d/01_first will be parsed before /usr/local/etc/sudoers.d/10_second. Be aware that because the sorting is lexical, not numeric, /usr/local/etc/sudoers.d/1_whoops would be loaded after /usr/local/etc/sudoers.d/10_second. A consistent number of leading zeroes in the file names can be used to avoid such problems.
