Everyone knows the C-I-A triad for information security: security is about protecting the Confidentiality, Integrity and Availability of systems and data. In a recent post, Warren Axelrod argues that Availability is the most important of these factors for security, more important than Integrity and Confidentiality – that C-I-A should be A-I-C.
