The triad of cybersecurity, commonly known as the CIA triad, refers to the three fundamental principles that guide the protection of information systems and data in cyberspace: Confidentiality, Integrity, and Availability. These components form the foundation of cybersecurity strategies and are essential for safeguarding digital assets against cyber attacks, unauthorized access, data breaches, and system disruptions. Each component plays a distinct but interconnected role in ensuring that information systems remain secure, reliable, and trustworthy in an increasingly technology-driven environment. Confidentiality refers to the protection of sensitive information from unauthorized access or disclosure. It ensures that only authorized individuals, systems, or entities can view or access specific data. In cyberspace, confidentiality is critical because organizations store vast amounts of personal, financial, and strategic information that could cause severe damage if exposed. Confidentiality is maintained through various technological and procedural measures such as encryption, authentication, access control mechanisms, and data classification. Encryption converts readable data into coded form, making it inaccessible to unauthorized users even if intercepted. Authentication methods such as passwords, biometrics, multi-factor authentication (MFA), and digital certificates verify the identity of users before granting access. Access control models like role-based access control (RBAC) and least privilege principles ensure users only access information necessary for their roles. Confidentiality can be compromised through cyber attacks such as phishing, social engineering, insider threats, eavesdropping, and hacking activities. For example, when hackers steal customer credit card data from an e-commerce platform, confidentiality
