#Amnesia sql injection tool code
Furthermore, AMNESIA doesn’t consider there are a certain types of code obfuscation or query development techniques that could make this step less precise and result in both false positives and false negatives. However, the primary limitation in AMNESIA according to Ramaraj is that the technique is dependent on the accuracy of its static analysis for building query models for successful prevention of SQL injection. Validates each query statement against the AMNESIA models.

In the web application architecture there are five layers browsers, networks, web servers, web applications and databases. The high level system components of web applications are shown in figure 1. Web applications are an application running over a network such as the internet or an intranet, enable website to become dynamic by making connections within the database. Index Terms-Cybercrime, SQL Injection, SQLIA, Vulnerabilities, Web Application Security. One of the main threats on the web applications is SQL injection attacks that are extremely widespread in web applications. The global accessibility of web applications is a serious problem, rendering them vulnerable to attack. Web applications are infamous for security vulnerabilities that can be victimized by writers of malware and hackers. Therefore, it is important to protect web applications from illegal accesses. Then, the string is forwarded to the database server for checking as a single Structured Query Language (SQL) statement, if the received string compromised or injected it will cause data leakage. A string contains both the query itself and its parameters which can be user name and password. Usually these queries generated by the web applications servers such as ASP, JSP and PHP. Generally, web applications use queries statements to generate strings to interact with the database. Finally, the database server manipulate this requests by allowing storage, deletion, updating of the data, depending upon the SQL query and sends back the results to the application server. After verifying the database access, the web application server sends the Structured Query Language (SQL) requests to the database server. In addition, the web application processes commands and verifies security access to the database through middleware such as JDBC, SQLJ, or JDO API, ODBC. Finally, the web application passes these requests to database. Fourthly, the web server passes this request to the web application server. Thirdly, the web server handles this request based on an initial configuration like (HTTP, HTTPS, etc.) which can also handles these requests by “decoding" the webpage. Secondly, the web browser passes this request through the firewall to the web server. The results show that our model protects against 100% of tested attacks before even reaching the database layer. Evaluations have been performed using three different applications. We have tested our proposed model on all types of SQLIA techniques by generating SQL queries containing legitimate SQL commands and SQL Injection Attack. In this paper, we propose a novel concept of negative tainting along with SQL keyword analysis for preventing SQLIA and described our that we implemented. The lack of existing models in providing protections against SQL injection has motivated this paper to present a new and enhanced model against web database intrusions that use SQLIA techniques. SQLIA gains access to the back-end database of vulnerable websites, allowing hackers to execute SQL commands in a web application resulting in financial fraud and website defacement. Web Application Protection against SQL Injection Attack Ammar Alazab, Moutaz Alazab, Jemal Abawajy, Michael HobbsĪbstract-SQL injection vulnerabilities poses a severe threat to web applications as an SQL Injection Attack (SQLIA) could adopt new obfuscation techniques to evade and thwart countermeasures such as Intrusion Detection Systems (IDS).
