Whew! All taken care of! Or, is it?If you delete sensitive information (like patient health records, unencrypted credit card numbers, Social Security Numbers, etc.) on your computer, guess what? They’re still there! If an attacker manages to find a way into your network, he can still access that deleted info. After quickly sending that data to my computer’s recycle bin, I breathe a sigh of relief. Say I find hundreds or thousands of unencrypted credit card numbers stored by accident on my business network. When delete doesn’t actually delete, it can increase your vulnerability.
