1. Data Encryption
Common thieves often wipe a lost or stolen device to resell it, but a thief with some digital prowess may attempt to access sensitive data. While data encryption isn't going to be a foolproof method of safeguarding data in high-threat countries, it is the most practical way to thwart an attacker from accessing sensitive data. A number of standard file encryption programs are available including Microsoft's BitLocker for Windows 7 and Windows 8 PCs, FileVault for Macs, and open source alternative TrueCrypt. McAfee, Symantec and other endpoint security vendors also sell full-disk encryption or file and folder encryption.
