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.
