What concept refers to the ability of authorized individuals to access data when needed?

The concept of "availability" is central to ensuring that authorized individuals can access data whenever it is needed. In the context of information security, availability means that systems and data are up and running, and accessible to users in a timely manner. This involves maintaining the functionality of systems and ensuring that any potential disruptions are minimized, allowing individuals who have the necessary permissions to retrieve and utilize data without delay.

Access to critical information at the right time is essential for effective decision-making and operational continuity, which is why availability is a key principle in the broader framework of information security, often represented alongside integrity and confidentiality. This balance is crucial for organizations that rely on their data and systems to perform business operations efficiently and responsively.
