Forgive me for being a bit stupid if this isn’t the same kind of thing… A WP plugin (called TripWire) that looks like it does the same job – albeit much easier to install.

I notice it’s the second in a three-part series of security plugins which look very useful indeed.

Is there any difference between the functionality of the one mentioned above and AIDE?
