Availability means that information and systems are accessible and usable when needed by authorized users.

The scope of upplýsingatöryggi extends beyond just digital data to include physical records and the systems that process and store information. It involves a combination of technical safeguards, such as firewalls and encryption, administrative policies, like access control procedures and security awareness training, and physical security measures, such as locked server rooms.

Key areas within upplýsingatöryggi include network security, application security, data security, and disaster recovery. Organizations implement upplýsingatöryggi strategies to protect sensitive information, maintain business continuity, comply with regulations, and safeguard their reputation. Threats to information security are constantly evolving, ranging from malware and phishing attacks to insider threats and sophisticated cyber espionage. Therefore, upplýsingatöryggi is an ongoing process of risk assessment, implementation of controls, and continuous monitoring and improvement.
