The Cloud

I have several clients come to me worried about using the “cloud” for storage. It seems that the concern is having their information online and hackers can get to it.
Online backup companies, the good ones, are very secure. They use a 256-bit AES encryption.
256-bit encryption is referring to the length of the encryption key used to encrypt a data stream or file. A hacker or cracker will require 2256 different combinations to break a 256-bit encrypted message, which is virtually impossible to be broken by even the fastest computers. For you math geniuses, breaking a symmetric 256-bit key by brute force requires 2128 times more computational power than a 128-bit key. Fifty supercomputers that could check a billion billion (1018) AES keys per second (if such a device could ever be made) would, in theory, require about 3×1051 years to exhaust the 256-bit key space.
So, with that in mind, if someone broke into your house and stole your computer, they would have your information totally readable and un-encrypted. Which do you think is the greater risk. Happy surfing.
