Keeping Your Personal Data Secure on the Cheap [Tips]

Some data are more sensitive than others. Whether it's some top-secret business documents or simply just baby photos you'd rather not let others see easily, keeping that data secure in your hard drive is of great importance and shouldn't be taken for granted. There's always the remote chance that a hacker might access your computer or some thief takes your hard drive, as what happened to a local celebrity recently. So what can you do about it?


Here's where encryption comes in. Yes, it sounds pricey. No, you don't need to spend a single peso for it. Let me show you two programs that can do the necessary encryption for you, all free to download, and easy to use.

TrueCrypt

This software allows a user to create encrypted partitions or even encrypt full hard drives, with a choice of 4 industry-standard encryption methods and 3 hash algorithms to use.

It also has an easy-to-use user interface and wizard to help one set-up an encrypted partition or drive quickly. Once set-up, the encrypted drive or partition acts like any other unencrypted one of its kind, with no serious performance or access issues, so you can start moving sensitive data and opening them directly from there.

As for how often you'll be asked for your password when accessing your encrypted partition/drive, the program only will only ask for it each time you mount it to your computer, so it's not tedious at all to work with, nor does it make substantial changes to your regular workflow.

TrueCrypt can be found here and is available on Windows, Mac, and Linux. If you'd like to see and determine for yourself if it's easy for you to use, you can look at the beginner's guide here.

7-zip

Yup, that veritable Swiss army knife of file compression is also handy when it comes to protecting your data. How? Simple, just add a password to the archive file you create.

Granted, it's not as flexible as TrueCrypt in that you're simply encrypting a defined set of files instead of creating a veritable stronghold where you can shuffle data in and access it quickly, but for times when you're transferring sensitive data from one computer to another, or you're protecting data that won't be used often, it does the trick nicely.

Another advantage is that encrypted archive files don't need any special software to be installed on the other end. Any file compression program will be able to handle opening that encrypted archive (given the correct password, of course).

7-zip can be found here and is available on a wide variety of OS platforms, including the usual suspects – Windows, Mac, and Linux.

To be fair, other popular file compression programs like WinZip and WinRAR are also able to encrypt archives they create. If you're already using those utility programs, you can also use them to add passwords to archives you create.

Other considerations

Any of these programs will fail at protecting your data if you're not equally careful with your passwords, though, so as a bonus, here are some quick tips you could use in conjunction with the programs above and log-ins in general to better secure your password.

  • Use a combination of uppercase and lowercase letters plus numbers in creating your password. If possible, throw in some spaces and underscores as well.
  • Be creative with your passwords. Avoid using commonly-used passwords like “123456” and “password”. The easier you make it for hackers to guess your password without even resorting to advanced tools, the easier you make it for people to access your data.
  • Use different passwords for different sites and encrypted materials. While it is tedious, it does prevent someone from easily accessing your files all the way to your e-mail if you stick with just one password for all of those.
  • Change your passwords often.
Remember that your data is only as secure as you make it to be.
