Enforcing Distributed Database Security using Multi-Scope based Authentication and Enhanced Distributed Firewall

The data is the most valuable asset of any organization, it resides data in the database system that is used to store data of every running application. So the security of database is very important. One of the most widely used types of a database is Distributed Database which has the capabilities of both a relational database and distributed network architecture. Hence the security of database is of the prime concern and at the same time, it is very tough to ensure, because different types of attackers and hackers are trying everything to compromise the distributed database security. Various researches are done to preserve the distributed database security but some security problems are still unresolved. In this paper, we propose the use of Multi-scope based authentication and Enhanced Distributed firewall by which the integrity and security of distributed database can be achieved.

Security Issues of Firewall

The need of Network Security is accelerating at the same pace as that of increased Internet usage. Network Security prevents from illegitimate admittance, hacking andauthentic data transportation. Network Security consist of provisions and policies adopted by a network administrator to preclude and monitor unauthorized access, alterations, perversion, declination of a computer network and network-accessible resources. Network Security is achieved by Firewall. Firewall is a hardware or software device which is designed to permit or refuse network transmissions based upon certain protocols. Firewall is a locus at the endpoints of the system which strains out all illegitimate traffic and users. But conventional or traditional firewalls rely stricly on the restricted topology and restrained entry points to function; which results in difficulty in filtering certain protocols, end-to-end encryption problem etc. Hence, it resulted in the evolution of Distributed Firewall which strengthens the network security policies without delimitating its topology from inside or outside. Distributed Firewall is a host-resident security software application that protects the enterprise network’s servers and end-user machines against unwanted intrusion. This paper is a literature review paper focusing on traditional firewalls, it evolution, security issues various policies and the concept of distributed firewall.
