Abstract: Network security is a crucial aspect of information technology, essential for safeguarding sensitive data in an increasingly interconnected world. This paper explores the fundamental concepts and techniques of network security, focusing on the CIA Triad (Confidentiality, Integrity, Availability), various threat types, and risk management strategies. Key techniques such as encryption, firewalls, intrusion detection systems (IDS), and virtual private networks (VPNs) are discussed, providing a comprehensive overview of how these methods protect networks from a range of cyber threats. Through detailed explanations, tables, and figures, this paper aims to enhance the understanding of network security principles, enabling organizations to implement effective security measures.
