Valerie wants to check to see if a SQL injection attack occurred against her web application on a Linux system. Which log file should she check for this type of information?

SQL injection (SQLi) attempts are sent as HTTP or HTTPS requests to a web server, meaning that Valerie will be able to see the attacks in the web server log. Domain Name System (DNS) logs, if available, will not show these. Auth logs show logins, not web or SQL Server queries or requests. Unlike Windows, there is no security log file for Linux, although there is a secure log for some systems.
