Network Security and Cryptography: A Qualitative Exploration and Recent Advancements

Network security and cryptography as a concept deal with network and data protection. Data security involves transmission of data securely even over an unreliable network whereas network security involves hardening of the network and thus preventing any unauthorized access. Both public and private networks come under the purview of network security. With increasing penetration of internet, e-commerce and social networking application and others IOT devices, a large amount of data is being generated every instant. Many countries have made ‘Right to be forgotten’ a fundamental right for their citizens the prominent example being GDPR of the European Union. Thus importance of data security has escalated in this modern digital world. In this paper, an attempt has been made to provide a lucid analysis of various terms and technologies involved in state of the art broad range network security and cryptography algorithms. Internet receives a special attention to apprise users with basic security measures.
