REVIEW ON REDUNDANCY REMOVAL OF RULES FOR OPTIMIZING FIREWALL

P.R.Kadam, V.K. Bhusari

Abstract: Firewalls are such a system, designed to prevent unauthorized internet access to or from private networks. A firewall checks all incoming and outgoing traffic by analyzing the data packets and then by using different policies determines whether to accept or discard the traffic. It is important to boost the firewall policies to improve network performance. The performance of the firewall is critical in enforcing and administrating security when network is under attack. Growth of the Internet with the increasing civilization of the attacks is placing stiff demands on firewall performance. It has been noticed that firewall policies are badly outlined and very erroneous. So it is very important to increase the performance of the firewall with good design of policies. Firewall performance can be optimized using various techniques like, optimizing firewall rules, optimization using data mining techniques. Firewall policies cannot be shared across domains as it contains confidential information and also various security holes are also present. Virtual private network integrated with mutual firewall protect the external network from encipher drift freight with minimum cost. Previous work gives emphasis on cross-domain privacy-preserving interfirewall optimization by removing interfirewall policy redundancies with preserving privacy. This privacy preserving protocol identifies rules of two adjoining firewalls resting between separate domains. This protocol sustains no more online packet process cost and offline process time is also less [16]

Keywords: Civilization, Redundancies, Adjoining, Privacy, Stiff.
