What aspect does the principle of availability focus on?

The principle of availability is a fundamental concept in cybersecurity, primarily focusing on ensuring that information and resources are accessible to authorized users whenever they need them. This means that the systems and data must be up and running, ready for use, without unnecessary delays. It encompasses measures such as implementing redundant systems, regular maintenance, and robust disaster recovery plans to address potential disruptions.

While accuracy, confidentiality, and legal protection of data are all important aspects of data security, they do not directly relate to availability. Ensuring data is accurate pertains more to data integrity, which focuses on the correctness of the data. Protecting confidentiality ensures that sensitive information is kept secret from unauthorized users, and legal protection involves compliance with laws and regulations regarding data handling. Availability, on the other hand, is solely concerned with the ability for users to access the information and systems they need in a timely manner.
