Got a new Mac computer or simply a new found design to protect your precious files? We commend you for your journey to protect what is yours and shouldn’t be available to others. Follow the steps below as the first step in protecting data on your Apple Mac Computer, Laptop, or Desktop.
1. Protect your whole computer
Having a Mac you can encrypt the whole drive, easily and without changing anything else, simply turning on “File Vault”
This encrypts your whole hard drive and protects the contents of it, ONLY when the computer is turned off. This is important, without it, anyone can take the computer, remove the hard drive and take the contents (files or programs) without a problem, even if there is a “password” on the computer it needs to have FileVault turned on to completely encrypt the files and keep people from taking the files. Make sure you have a screen saver set which requires a password to wake it, or shut down the computer every time you leave System Preferences -> Security, the checkbox “Require password to wake this computer from sleep or screen saver” http://osxdaily.com/2011/01/17/lock-screen-mac/
2. Protect Individual Files in Preview or PDF
File>Print>PDF (bottom left hand corner)>save as PDF>security options
And add your password.
This is probably the best option for sending documents to and from clients, but don’t send the file and password in the same email, send them in different emails with different subjects.
3. Protect Any & All file or folder
If you have a lot of other files and folders, it’s best to use a free program (http://www.truecrypt.org/) to protect them. It says it has been decommissioned, but it’s still the best and safest available. You can create encrypted folders where you place all your files/folder. This can be done on your computer, USB flash drive, or any other external drive. This is the best and most safe way to protect client data. Just don’t make the password easily known or found, such as saving it in a text or MS Office file. Best to create a pass-phrase you can remember and don’t write down or use a program to remember all your passwords such as https://agilebits.com/onepassword This program encrypts your data, you always keep it in this encrypted format until you need to access it, upon which you un-encrypt (mount) and view the data. The folder is open to view until you close or dismount it.
If you want an easier program there are many such as https://agilebits.com/knox but it will cost a few bucks.
