In the context of cybersecurity, what does "availability" refer to?

In cybersecurity, "availability" is a fundamental principle that refers to ensuring that authorized users have access to information and resources when they need them. This concept is crucial because, in a secure environment, it is not enough for data to be safe from unauthorized access; it also must be available for legitimate users to utilize effectively. This encompasses measures such as maintaining hardware, implementing redundant systems, conducting regular backups, and defending against denial-of-service attacks that could render information inaccessible.

The focus is on uptime and the ability to retrieve and use information without undue delay or obstacles. This principle plays a vital role in organizational continuity, disaster recovery planning, and overall operational efficiency, making it essential for organizations to prioritize availability within their cybersecurity strategies.
