Availability is one of the three pillars of the CIA triad, a model that defines the principles of information security. Availability describes the concept of data consistently and readily being accessible for legitimate users. Availability ensures that the network and systems are operational and resilient to disruptions, such as denial-of-service attacks, hardware failures, or natural disasters. Availability also involves maintaining backup and recovery procedures, load balancing, and redundancy mechanisms. References:
