What does confidentiality entail in cyber security?

Confidentiality in cybersecurity refers specifically to the protection of sensitive information from unauthorized access and disclosure. It ensures that only those individuals or systems with the proper permissions can view or manipulate the data. Confidentiality is a fundamental principle of information security and is achieved through various means, including encryption, access control measures, and secure communication protocols. By safeguarding data confidentiality, organizations can help prevent data breaches, leaks, and other forms of unauthorized exposure that could lead to significant harm or loss.

While the other options describe important aspects of cybersecurity, they pertain to different principles. Verification of identity relates to authentication processes, maintaining the accuracy of information deals with integrity, and ensuring timely access to data is about availability. Each plays a crucial role in a comprehensive cybersecurity strategy, but confidentiality remains focused on protecting data from being accessed by unauthorized individuals.
