Top Tips To Protect Sensitive Files With Disk Utility

Information security is a very crucial issue in today’s online world. With identity theft, credit card fraud, and other cyber crimes running rampant, it is very important to protect all your data. Hacking is one of the ways cybercriminals get your information. So, if you’re storing sensitive information on Mac, having a password is not enough. You need a strong Mac drive encryption to protect your computer against unauthorized access.

Aside from having secure passwords, you can encrypt your data on your Mac for added security. There’s no need to buy expensive third-party apps to protect your data. All you need is Disk Utility for your hard drive encryption. You can choose to encrypt the whole drive or a few specific files or folders.

To enable hard disk encryption, follow these steps:

  1. Open Finder.
  2. Find Utilities > Disk Utility.
  3. Double-click on the Disk Utility icon.
  4. While Disk Utility window is open, click File at the top.
  5. Click New Image and choose Image from Folder.
  6. Choose the specific folder you want to encrypt and click Choose.
  7. Enter the name for your encrypted disk image and choose what type of encryption you want. You can choose 128 or 256-bit encryption.
  8. Click Save, and then set up your password.

Never lose your password because that means you’ll lose access to all the files that have been encrypted. This is one of the disadvantages of Mac drive encryption. What you can do is write it down and keep it somewhere secure.

Here are some other tips to keep your sensitive information protected:

  1. Aside from encrypting your folders, you can also enable full hard disk encryption. You can use Apple’s FileVault to encrypt your hard drive using XTS-AES 128 algorithm. So, in case your Mac gets stolen or lost, other people won’t be able to access your files or any data on it. To enable FileVault, just go to System Preferences > Security & Privacy > FileVault and choose Turn on FileVault.
  2. Lock your screen when you step away. Having a login password is not enough; you also need to set up a password when you wake your computer. So, even if you have to step out to buy something or go to lunch, other people won’t be able to access your files.
  3. Disable automatic login. The first time you set up your Mac and create a user account, automatic login is set by default. That means you won’t need a password when you start up your Mac. Automatic login means that anyone can start up your Mac and have access to your files. To disable automatic login, go to Login Options and turn off automatic login.
  4. Get rid of unwanted files and other junk on your computer by running Outbyte MacRepair. It cleans up your Mac of temporary files, log files, caches, and other unnecessary files that could be malicious.
  5. Install antivirus. Malware could be installed on your Mac by downloading malicious files or accessing phony sites. Protect your Mac and your data by installing a good antivirus.
  6. Use a password manager. Complicated and unique passwords are very easy to forget. You need to create a complex and secure password for all your login credentials, including that for your computer, email, apps, and encrypted files. It will be difficult to remember one complex password, much less all of them. You can use a password manager to save passwords and generate unique passwords.

By following these tips and using the Mac drive encryption feature, you can keep other people from accessing sensitive data from your computer.
