Why A Little Paranoia Is Good For Security, And A Mac App That Permanently Deletes Files

When it comes to security, a little paranoia goes a long, long way. What most Mac users don’t know is how many outside forces attempt to hack their way into the Mac each day. If you’re connected to the internet, or office or school networks, your Mac is vulnerable.

If everyone out there wants to get inside your Mac, what can you do? The obvious precautions will help, of course. Lock down the firewall on your network’s router. Set up the security options on your Mac. Don’t download files from unknown or untrusted sites.

What about files on your Mac? Guess what? Whenever you delete a file on your Mac it’s not really deleted. The Mac turns off the light so the deleted file seems deleted (you can’t see it), but it’s still there, still occupies space on your storage, and is still retrievable by someone snooping around on your Mac.

There are two ways to put your paranoia about security to good use when it comes to deleting files.

In the Finder’s menu are two settings. Empty Trash and Secure Empty Trash. Use the second option. It may take longer, but it’s more secure because it overwrites a trashed file multiple times.

Or, use Shredit X, an app that does even more to delete files permanently.

Shredit Setup

Shredit X’s setup is straightforward with large, clear buttons so you know exactly what you’re about to shred– files, folders, or even free space on your Mac.

Shredit X Preferences

Shredit X’s Preferences are a bit more complex, but once you set them, there’s little need to change them later.

More Shredit Preferences

The advantage to using Shredit becomes obvious as the value of files on your Mac increases. Shredit will permanently delete files and folders from the Mac, an external disk drive, a USB flash drive, CD-RW discs, and even floppy disks.

There’s a Confirm Before Shred function, and Shredit X’s technology complies with U.S. Department of Defence electronic shredding standards. How valuable is Shredit X? Use it to completely wipe a Mac’s hard disk drive before you sell it, give it away, or dispose of it.

There’s even a simple File Shredder Test to help you determine whether or not you’ll need Shredit X’s advanced shredding capability.

Other than the Preferences interface, which isn’t always self explanatory or friendly to security neophytes, Shredit X can help sooth your paranoia.
