DISTRIBUTED FIREWALL WITH DYNAMIC INTRUSION DETECTION MODULE

Computers and Internet, both are becoming an essential part of life. With computer networks we are sharing resources, exchanging information, and number of personal transactions which must be secured from unauthorized access, with Network Security we can prevent and detect unauthorized access. So, we can maintain integrity, confidentiality and accessibility of computer networks. One way to achieve Network Security is FIREWALL. A firewall is a system which monitors and filters traffic and gives entry/ blocks data packets based on a set of security rules. Distributed firewall is introduced to eliminate the problems which are difficult to solved in conventional firewalls. Distributed firewall is not restricted by topology and entry point as conventional firewall. Distributed firewall secure critical network endpoints, it provides unlimited Scalability and overcomes single point of failure problems. In this paper, we have proposed Distributed Firewall with Dynamic Intrusion Detection Module to achieve elevated security to the network.
