Study Notes
- Network security is a multi-faceted approach to shielding computer networks and transmitted data from unauthorized access, attacks, and harm.
- It encompasses technologies, processes, and policies that safeguard data confidentiality, integrity, and availability.
- Implemented measures include firewalls, intrusion detection systems, VPNs, and access controls to restrict unauthorized access and ensure secure communication.
- Regular updates, patches, and security audits maintain a robust network security posture.
- User education and awareness minimize human error in potential security breaches.
- Cryptography is a fundamental network security component, enabling secure communication and data protection through mathematical algorithms.
- Encryption secures data even if intercepted during transmission, with symmetric key cryptography using a single key and asymmetric key cryptography employing a pair of public and private keys.
Test your knowledge about the comprehensive approach to protecting computer networks and the data they transmit from unauthorized access, attacks, and damage. Explore various technologies, processes, and policies designed to safeguard information confidentiality, integrity, and availability.
