Information Security
Information Security (pronounced as /ˌɪnfərˈmeɪʃən sɪˈkjʊərɪti/), also known as InfoSec, is the practice of protecting information by mitigating information risks. It includes procedures that are used to protect electronic data from unauthorized access or alterations, both when it is being stored and when it is being transmitted from one machine or physical location to another.
Etymology
The term "Information Security" is derived from the concept of 'information' (from the Latin 'informatio', meaning to shape the mind) and 'security' (from Latin 'securus', meaning free from danger). The term was first used in the late 20th century, with the advent of computers and digital information.
