What is information assurance? Explain the classic pillars of Information assurance.

 Information assurance refers to the practice of protecting and securing information and the systems that store, process, and transmit it. The classic pillars of information assurance are:

1. Confidentiality: Ensuring that information is only accessible to authorized individuals or entities and protected from unauthorized disclosure or access.

2. Integrity: Ensuring that information is accurate, complete, and unaltered throughout its lifecycle. Measures are implemented to prevent unauthorized modification or tampering of data.

3. Availability: Ensuring that information and the systems that store and process it are available and accessible to authorized users when needed. This involves implementing measures to prevent disruptions, downtime, or denial of service attacks.

These pillars are the foundation of information assurance and are essential for maintaining the security, reliability, and trustworthiness of information and the systems that handle it.
