IMPROVE NETWORK SECURITY SYSTEM IN VIETNAM USING REVERSE METHOD

Abstract

This paper presents the results of evaluating the security level of a network based on reverse engineering. A number of common network attacks, such as DDoS, SQL Injection, Reverse TCP were emulatedto quantify and evaluate the level of security defenses of the system based on simulation experiments. Through the threat analysis and security metrics, the level of safety and security of the network were indentified. Three scenarios for a network attack using White Box intrusion detection methods include: (a) attacking a web server from an internal network, (b) attacking from outside in the case of a built-in old firewall and (c) external attacking in the case of a new generation firewall. The results showed that (a) the severity of the attack caused serious results (server paralysis up to 95%); (b) the server paralysis rate was decreased to 63%; and (c) the server paralysis rate was only 19%. The results are promising to help administrators to build better safety and security systems as well as to prevent and limit network connections and threatens attacking their systems.
