Abstract


With the development of computer network technology , the Web-based applications are becoming increasingly popular . Attacks against Web applications become the research focus of the current network security attack and defense in these attacks , SQL injection attack has become the focus of attention . Attack by SQL injection attack not only on the server data tampering, loading information can also implanted backdoors , thus seriously affecting the normal operation of the site will eventually have serious consequences and even lead to the collapse of the site . , Through SQL injection attacks , an attacker can illegally obtained unrestricted access to the database of Web applications , enterprise and network user 's confidential information , economic loss and inconvenience to the enterprise network users , so this strict to prevent SQL injection attacks . Therefore , for the SQL injection attack prevention technology research has important practical significance . It is for this security problem , following in-depth research . Existing SQL injection attacks and the resulting harm , according to the current domestic and SQL injection attacks its detection prevention research progress , thesis target depth analysis by the principle of SQL injection attack tool , combined with the principles and features of the various injection attacks technologies , design and realization of SQL injection attacks the scan analysis tools ; prevention technology research and analysis , and the existing SQL injection SQL injection prevention model put forward an improved three . Paper design and implementation of SQL injection attacks scan analysis system to quickly on site page scan and find the SQL injection point , to help people discover injection vulnerability exists in the application , so as to better safeguard the security of the application . The system contain a new type of character and contains two numeric increase in SQL injection , can increase the probability of successful injection attacks ; judgment SQL injection point using multi-threading technology , increased attack speed to a certain extent ; attack , brute force solutions and dictionaries guess solution to improve the efficiency of the injection attacks . At the same time , the paper presents three preventive model to some extent compensate for the deficiencies of the current prevention technology .
