In this paper, an attempt has been made to review the various Network Security and Cryptographic concepts. This paper discusses the state of the art for a broad range of cryptographic algorithms that are used in networking applications This paper also highlights the terms of computer security and network security. I would like to study the issues like password security, network sniffing, intrusion detection, firewalls and network structure in detail. As the risks are many in a business organization, there should be a complete system dedicated to securing the networks. We will also discuss malicious users that why they do not possess a high level of programming skills and instead make use of tools available on the Internet.
