What does the CIA triad in cybersecurity stand for?

• A. Control, Integrity, Access
• B. Confidentiality, Integrity, Availability
• C. Confidentiality, Investigation, Authentication
• D. Compliance, Integrity, Assessment

Answer: (B)

The CIA triad in cybersecurity stands for Confidentiality, Integrity, and Availability, which are three foundational principles that guide the development and implementation of effective security policies and practices.

Confidentiality refers to protecting sensitive information from unauthorized access and ensuring that data is only accessible to those who are permitted to view it. This principle is crucial for maintaining privacy and protecting sensitive data against breaches.

Integrity ensures that the information remains accurate and unaltered unless done so through authorized means. It protects data from being modified or destroyed by unauthorized users and guarantees that stakeholders can trust the data they are using.

Availability ensures that information and resources are accessible to authorized users when needed. This principle emphasizes the need for reliable systems and infrastructure that remain operational and accessible, even during attacks or failures.

Understanding the CIA triad is essential for establishing a robust security posture, as it addresses the fundamental aspects of protecting information in various contexts.
