CIA Triad

The CIA Triad is a foundational concept in cybersecurity that represents the three core principles essential for securing information systems:

1. Confidentiality: Ensuring that sensitive information is only accessible to authorized individuals or systems. This prevents unauthorized access to data.

   • Example: Encryption, access controls.

2. Integrity: Ensuring that information remains accurate, consistent, and unaltered, except by authorized users. It protects data from being tampered with or modified maliciously.

   • Example: Hash functions, digital signatures.

3. Availability: Ensuring that information and resources are accessible and usable when needed by authorized users. This involves maintaining system uptime and preventing disruptions.

   • Example: Redundant systems, backup processes, disaster recovery plans.

Together, the CIA Triad helps guide the development and implementation of security policies and controls to protect information in an organization.
