FCheck

FCheck is a cool open-source PERL script that helps keep your system safe by detecting intrusions and enforcing policies. If you're worried about what changes have been made to your files, this tool is super handy. The best way to know what's been altered on your system is to take a snapshot of everything before any changes happen.

How FCheck Works

So, here's where FCheck comes in. It generates that important "pristine" snapshot of your entire file system. Once it's set up right, it will also keep an eye on your system and let you know right away if anything strays from that original snapshot.

Compatibility with Different Systems

This tool isn't just for one type of computer. FCheck works with Windows 95/98/NT/3.x and Unix servers. It uses comparative system snapshots to help you catch any differences. If something gets changed—like files being added or deleted—you'll get notified through your event management system, printer, or even email!

An Open Source Solution

The beauty of FCheck is that it’s built on the PERL script and can run on any platform that supports PERL and long filenames. That means it's not just for UNIX systems; you can use it on Win32 platforms too, as long as you have PERL installed.

No Licensing Hassles

You might be wondering about other tools out there. Right now, there's only one other baseline security tool like this—Tripwire—but it requires licensing fees and agreements. All the code for FCheck is created from scratch by its author, so you won’t have those annoying costs! Plus, anyone can use it for free if they want a solid security measure.
