Abstract

Encryption is a process of obfuscating data with an algorithm that uses keys and certificates so that if security is bypassed and data is accessed or stolen by unauthorized users, then it will be useless, unless the keys that were used to encrypt it are also obtained. This adds an additional layer of security over and above access control, but it does not replace the need for an access control implementation. Encrypting data also has the potential to considerably degrade performance, so you should use it on the basis of need, as opposed to implementing it on all data as a matter of routine.
