NETWORK BASED SECURITY INFORMATION SYSTEM
In today’s trend of information and security treat the main tool use in businesses to protect their internal network is the firewall. A firewall is a hardware and software system that allows only external users with specific characteristics to access a protected network. While firewalls are indispensable protection for the network at keeping people out, today’s focus on e-business applications is more about letting the right people inside your network. Network security can be defined as protection of networks and their services from unauthorized modification, destruction, or discovery, and provision of guarantee that the network performs in critical situations and have no harmful effects for neither user nor for employee. The International Telecommunication Union ITU, the International Information Processing IFIP, World background Organization WCO is all running to develop standards related to electronic commerce. DES was the result of a research project set up by International Business Machines (IBM) corporation in the late 1960’s which resulted in a cipher known as LUCIFER. In the early 1970’s it was determined to commercialise LUCIFER and a number of important changes were introduced. The encryption technology for network security, implementing information encryption and transmission on the network by using DES algorithm. Information security strategies deal with two issues: protecting the integrity of the business network and its internal systems. The field of information Technology (IT) Security as information technologies is represent merely component of information systems. A setting of a security can be defined as an organized framework consisting of concepts, beliefs, principles, policies, procedures, techniques, and measures that are required in order to protect the individual system property as well as the system as a whole against any intentional or unplanned threat.
1.1 BACKGROUND OF STUDY
Information system occupies a vital and unique position in any organization by virtue of the data and information, which it contains. Security of information is of great importance to any given organization this makes the information reliable since information stored can be referenced whenever necessary access by unauthorized persons.
This project analysis the activities and importance of securing information in any organizations and to see that the information is accurately maintained to help the management in decision making and control of the diverse activities of the organization.
