Abstract: In order to understand the concept given to the Central Intelligence Agency in its origin, the influences that led to its formation must be analyzed. The CIA is not a product of historical evidence. The need for it was previous, but it were the recent attitudes and events that shaped the agency and arranged its clauses and limits. The CIA became a branch and a model of security analysis, taking "Confidentiality, Integrity and Availability" as the main moral code to secure an object.
