Which of the following is NOT considered a component of cybersecurity?

The correct answer identifies isolation as the option that is not typically categorized as a core component of cybersecurity. When exploring cybersecurity, components are usually framed within key principles such as confidentiality, integrity, and availability, often abbreviated as the CIA triad.

Authentication serves to confirm the identity of users or devices, ensuring that only authorized individuals can access sensitive information or systems. Availability ensures that data and services remain accessible to authorized users when needed.

Nonrepudiation is the assurance that someone cannot deny the validity of their digital actions, which is crucial in maintaining trust in communications and transactions.

While isolation may play a role in specific cybersecurity strategies or practices, such as air-gapping systems or creating network segments to reduce risk, it is not recognized as one of the main foundational principles of cybersecurity like the other three components are. Thus, isolation stands out as not fitting the central framework of cybersecurity.
