Triad of AIC

Three main pillar of security are:

Confidentiality, Integrity & Availability, abbreviated as AIC or CIA.

Each organization may focus on one aspect, albeit taking care of the other two. For example, military organizations are more focused on keeping data confidential whereas financial organizations focus on integrity and Internet Service Providers focus on availability. None, however, forgets the other aspects of security.
