Security Events Log is the core feature in GD Security Toolbox Pro. It is created to log all kinds of security-related events. This includes basic things like user login and logout, registration of new accounts, 404 errors for missing page attempts, 404 pages with query strings… Most plugin addons add their own events.
Events log panel shows a lot of information about each event: IP (with optional Geo-Location and options to get blacklist status, location, and who is information), request type (POST/GET, HTTP protocol), URL, and date. Different events log a lot more things visible in the Data column in form of a popup. From the events log you can ban any IP listed.
The plugin includes a notifications system that currently can send a daily and weekly digest of events logged in the previous day or week.
