Method for Simulating SQL Injection and DOS Attack

Data is the most important aspect in any computer system. Database powered Web applications are used by the organization to get data from customers and the most used database in SQL. Attacks are created day by day to exploit the database and extract information without authorization. SQL injection in such attack poisons dynamic SQL statements to access the SQL database. GNS3 is an effective tool to model and emulate this attack. Using this setup, we can simulate the setup of particular network systems, execute SQL injection attacks on victim computers and retrieve network logs to analyse them. On the other side, denial-of-service (DoS) attacks are yet another major cybersecurity threats, and more researches have been going on developing DoS attack detection techniques. Modelling DoS attacks is an easy simple job because there are very big contemporary DoS attacks, and in most of the instances, it would be impossible to simulate them. The graphical network simulators can be used (GUI) to detect the attacks. Due to heavy traffic, it is subjected to hammering of trustworthiness over the last few years of uncertainties regarding its reliability. In order to avoid that the filtering based on source IP address is integrated with ports by using an access control management. The most important aim of this work is to simulate an SQL injection attack and denial-of-service (DoS) attack situations in a complex network environment. This model can help researchers to develop the effective countermeasures.
