Which of the following is NOT a characteristic of information security?

Ensuring high accessibility of data is not typically considered a characteristic of information security in the same way that the other options are. The core principles of information security are often encapsulated in the concepts of confidentiality, integrity, and availability, which are collectively known as the CIA triad.

The characteristics associated with information security focus primarily on protecting information and systems from threats and ensuring they work as intended without unauthorized interference. For instance, maintaining a low probability of theft directly relates to safeguarding sensitive information, while preventing disruption of services addresses the need for systems to be operational and not subject to damage or unavailability caused by attacks. Additionally, reducing data corruption risks is integral to preserving the accuracy and integrity of the information.

While accessibility is important, in the context of information security, it does not underscore the proactive measures taken to protect information from unauthorized access or damage. Instead, high accessibility can sometimes be at odds with security measures, which may intentionally limit access to protect sensitive data. Thus, the focus on high accessibility contrasts with the primary aims of information security, which prioritize safeguarding data and ensuring its proper functioning rather than simply making it highly available.
