Description
The server error logs are invaluable because they can also be used to identify potential problems and enable proactive remediation. Log data can reveal anomalous behavior such as “not found” or “unauthorized” errors that may be an evidence of attack attempts. Failure to enable error logging can significantly reduce the ability of Web Administrators to detect or remediate problems. The LogFormat directive defines the format and information to be included in the access log entries.

ℹ️ Check
Enter the following command: grep "LogFormat" /usr/local/apache2/conf/httpd.conf. The command should return the following value: LogFormat "%a %A %h %H %l %m %s %t %u %U \"%{Referer}i\" " combined. If the above value is not returned, this is a finding.

✔️ Fix
Edit the httpd.conf file and add LogFormat "%a %A %h %H %l %m %s %t %u %U \"%{Referer}i\" " combined
