What is need of Network Security? Explain Integrity, Confidentiality and Availability in relation to Information Security.

Network Security is essential to protect sensitive data, maintain privacy, and ensure the reliability and performance of network systems. It safeguards against unauthorized access, cyber threats, data breaches, and attacks that can disrupt operations or compromise data integrity.

Key Principles of Information Security:

1. Integrity:

   • Ensures data accuracy and consistency over its lifecycle.
   • Prevents unauthorized modifications, ensuring information remains unaltered from its original state.

2. Confidentiality:

   • Protects sensitive information from unauthorized access.
   • Ensures that only authorized individuals or systems can access sensitive data, maintaining privacy.

3. Availability:

   • Ensures reliable access to information and resources when needed.
   • Maintains system and network uptime, preventing disruptions that could hinder access to critical information or services.

These principles—integrity, confidentiality, and availability—are fundamental to creating a secure and trustworthy network environment, protecting both data and resources from diverse security threats.
