Safety Summons: Network Security Services

Abstract

Network security and cryptography is a subject too wide ranging to coverage about how to protect information in digital form and to provide security services. However, a general overview of network security and cryptography is provided. Network security is a complicated subject, historically only tackled by well-trained and experienced experts. When many systems are connected in a network it is very important to safe guard the data in each system. However, as more and more people become “wired'', an increasing number of people need to understand the basics of security in a networked world. Our paper covers different kinds of threats & firewalls in the network by implementation of different security services using various security mechanisms. Generally, the logical conclusion is to use both kind of algorithms and their combinations to achieve optimal speed and security levels. It is hoped that the reader will have a wider perspective on security in general, and better understand how to reduce and manage risk personally.
