Which principle of cybersecurity focuses on ensuring information is available when required?

The principle that focuses on ensuring information is available when required is availability. In cybersecurity, availability refers to the assurance that authorized users have access to information and associated assets whenever they need it. This aspect is critical for businesses and organizations that rely on timely access to data for their operations, decision-making processes, and service delivery.

Availability is often maintained through various means, such as implementing redundant systems, performing regular backups, and deploying failover strategies. These measures help to prevent disruptions from various threats, such as hardware failures, cyber attacks, or natural disasters. Ensuring availability is crucial in maintaining business continuity and preventing data loss that could impact the organization and its stakeholders.

Understanding this principle is vital in the context of cybersecurity, as it encompasses not just the technical aspects of maintaining access but also the policies and procedures that support ongoing access to information systems.
