Encryption is the in-word in internet security and privacy circles. It is also the word on the lips of law enforcement, and not in a good. See, encryption has always been there but it is only in the last decade or so that people decided to commercialize it on a large scale.
There before, the concept was too complicated for the regular computer user to be really concerned with it. Today there are any option for people looking to encrypt their information. This is in part because of the rise in online financial activities.
In addition, rise in cybercrime has branched out into identity theft meaning that people need to be careful with their personal information. Company servers which harbor sensitive information also need to be encrypted. The hack on Sony for example showed how expensive cybercrime can be.
Phone manufacturers and computer markets are in on the encryption as well. Google for example has taken encryption seriously with their Nexus devices running Lollipop and above.
This is especially so after the revelations that the US government was monitoring personal conversations and accounts for millions of Americans, and Google and other big companies were being accused of being party to the intrusion. Apple is also shipping the iPhone 6 with full encryption in default.
The two companies are suing AES encryption which is almost impossible to crack. In fat, Google and Apple cannot break into the phones themselves. It is this kind of security that law enforcement is uncomfortable with. This is because it cannot force Google or Apple to break into an encrypted device even with a court order because the companies have no way in.
Devices to encrypt
The first device you should encrypt is your phone. Your phone holds your most sensitive information. It is also the one device that you take everywhere with you. An encrypted device not only protects your information it also secures your identity.
The second device you should encrypt is your PC or laptop. This is especially important for people who work for companies that hold sensitive data. The IT person will make sure that your device is encrypted.
Microsoft provides encryption in the form of Bit locker for all windows PCs running Windows 7 and above. While Bit locker might slow down booting, everything else pretty much remains the same.
The third device that should be encrypted is the server. If a company uses servers to backup sensitive data then they need encryption with an AES key of at least 128 bits. That way the information stored is safe.
Encryption has some drawbacks, with these including reduced performance, increased costs and some unfriendly usability. Aside from that, it is perhaps something which everyone should consider.
