In the digital age, where data flows continuously across global networks, ensuring the confidentiality, integrity, and availability of information has become a paramount concern. This research paper explores the critical role of network security and cryptography in safeguarding digital communication. Network security involves the adoption of protocols, policies, and technologies aimed at defending networks against unauthorized access, misuse, and cyber threats. Cryptography, as a mathematical science, enables secure communication by converting plaintext into ciphertext through encryption and then reverting it back via decryption. This paper examines traditional and modern cryptographic techniques, security protocols, threat models, and architectures used to protect data in transit and at rest. Furthermore, it presents a simulation-based evaluation of various encryption algorithms, intrusion detection mechanisms, and real-world case studies to highlight the practical implementation of these technologies. The objective is to provide a comprehensive understanding of how integrated security models can be designed to resist evolving cyber threats and enhance digital trust in an interconnected world.
