Study on firewall system identify and troubleshoot the malignant packet detection using similarity index algorithm

Abstract

The usage of online network in day-to-day life is inevitable. Firewalls are used to safeguard essential networks from outdoor attacks to guide network access based on the firewall access rules. The firewall system plays an important aspect that protects from rule analyst and malignant attack which provides security to all the internet users. newlineThe firewall system is located between the concealed network and the Internet which enforces the security access rule by controlling the links to be established between the two or more networks. In every network traffic should pass through the firewall, which allows only acceptable traffic flows. The main purpose of this firewall system is to manage the network access to or from a secured network. Some difficulty with the process of firewall system is due to malfunction, it might be terrible to other fewer secured systems on the internal network. The detecting malignant packets are very significant in security issues. Therefore, this thesis proposes a Similarity Index Algorithm which is to detect the malignant packets in the firewall framework. The performance of the proposed firewall system is evaluated using Network simulator version 2 environments in terms of latency and malignant packet detection rate with respective to the number of nodes or computers newline newline
