Once a problem (we call it a vulnerability) is found in a computer system, the next step is figuring out how to fix it so that bad guys can't use it to break in. Here's how it's done:

• Setting up better defenses on your computers, like firewalls or virus scanners

• Keeping your software up to date

• Backing up your data so you can recover it if something goes wrong

• Making sure only the right people or computers can access certain information

• Watching more closely for strange activities that could mean someone is trying to break in

• Using better passwords and extra steps for logging in, like codes sent to your phone

• Teaching your team how to spot and avoid scams and other tricks

• Checking the Work

After you've done your best to fix or lessen the problem, you need to test everything again to make sure the solution works. It's like making sure the patch on the hole holds up and that no one can get through it anymore.

In simple terms, once you know there's a problem, you figure out the best way to fix it or at least make it less of an issue, and then you check to make sure your solution is solid.
