Every person will secure themselves from a stranger or outsider but it is generally ineffective from preventing a legitimate person from gaining access. Information that is stored in server, desktops, laptops, floppy disk or backup tapes is vulnerable to social engineering attack. An effective deterrent or tracking tool is the installation of access control, where all access to computer is controlled.

To encrypt the data, the originator of the data converts plaintext into ciphertext using an encryption key. In its simplest form, an encryption key is a programmed formula that the recipient of the data uses to decrypt the ciphertext. With the encryption techniques, it can help to prevent the information theft to obtain the company information as they don't know what the words are meaning about.
