Techopedia explains CIA Triad of Information Security

The CIA triad of information security was created to provide a baseline standard for evaluating and implementing information security regardless of the underlying system and/or organization. The three core goals have distinct requirements and processes within each other.

  • Confidentiality: Ensures that data or an information system is accessed by only an authorized person. User Id’s and passwords, access control lists (ACL) and policy based security are some of the methods through which confidentiality is achieved

  • Integrity: Integrity assures that the data or information system can be trusted. Ensures that it is edited by only authorized persons and remains in its original state when at rest. Data encryption and hashing algorithms are key processes in providing integrity

  • Availability: Data and information systems are available when required. Hardware maintenance, software patching/upgrading and network optimization ensures availability
