What does the CIA triad—confidentiality, integrity, and availability—represent in cybersecurity, and why is it fundamental?
The CIA triad in cybersecurity represents three core principles:
1. Confidentiality: Ensuring that data is only accessed by authorized individuals and remains confidential from unauthorized access.
2. Integrity: Guaranteeing that data is accurate, complete, and reliable. Any changes to data must be monitored and controlled to maintain its integrity.
3. Availability: Ensuring that data and systems are accessible when needed by authorized users. This includes measures to prevent downtime and disruptions.
The CIA triad is fundamental in cybersecurity because it provides a systematic framework for ensuring the security of information and information systems. By focusing on confidentiality, integrity, and availability, organizations can establish a comprehensive approach to protect their data and systems from various threats such as cyberattacks, data breaches, unauthorized access, and data loss. The CIA triad serves as a foundation for developing security policies, implementing security controls, and assessing the overall security posture of an organization.
