The vulnerabilities in most web applications enable hackers to gain access to confidential and private information. Structured query injection poses a significant threat to web applications and is one of the most common and widely used information theft mechanisms. Where hackers benefit from errors in the design of systems or existing gaps by not filtering the user's input for some special characters and symbols contained within the structural query sentences or the quality of the information is not checked, whether it is text or numerical, which causes unpredictability of the outcome of its implementation. In this paper, we review PHP techniques and other techniques for protecting SQL from the injection, methods for detecting SQL attacks, types of SQL injection, causes of SQL injection via getting and Post, and prevention technology for SQL vulnerabilities.

SQL injection attack (SQLIA) is a serious threat to web applications. A successful SQLIAs can have serious consequences to the victimized organization that include financial lose, reputation lose, compliance and regulatory breach. Therefore, developing approaches for mitigating SQLIA is paramount important. To this end, we propose an approach based on negative tainting along with SQL keyword analysis for detecting and preventing SQLIA. We have tested our proposed approach on all types of SQLIAs techniques by generating SQL queries containing legitimate SQL commands and SQLIA. We present an analysis and evaluation of the proposed approach to demonstrate its effectiveness in detecting and protecting SQLIA attack.

Database driven web application are threaten by SQL Injection Attacks (SQLIAs) because this type of attack can compromise confidentiality and integrity of information in databases. Actually, an attacker intrudes to the web application database and consequently, access to data. For stopping this type of attack different approaches have been proposed by researchers but they are not enough because usually they have limitations. Indeed, some of these approaches have not implemented yet and also most of implemented approaches cannot stop all type of attacks. In this paper all type of SQL injection attack and also different approaches which can detect or prevent them are presented. Finally we evaluate these approaches against all types of SQL injection attacks and deployment requirements.

SQL Injection Attack (SQLIA) is a technique of code injection, used to attack data driven applications especially front end web applications, in which heinous SQL statements are inserted (injected) into an entry field, web URL, or web request for execution. "Query Dictionary Based Mechanism" which help detection of malicious SQL statements by storing a small pattern of each application query in an application on a unique document, file, or table with a small size, secure manner, and high performance. This mechanism plays an effective manner for detecting and preventing of SQL Injection Attack (SQLIA), without impact of application functions and performance on executing and retrieving data. In this paper we proposed a solution for detecting and preventing SQLIAs by using Query Dictionary Based Mechanism.

The functionality of a web-based system can be affected by many threats. In fact, web-based systems provide several services built on databases. This makes them prone to Structured Query Language (SQL) injection attacks. For that reason, many research efforts have been made to deal with such attacks. The majority of the protection techniques adopt a defense strategy which results to provide, in extreme response time, a lot of positive rates. Indeed, attacks by injecting SQL are always a serious challenge for the web-based system. This kind of attack is still attractive to hackers and it is in growing progress. For that reason, many researches have been proposed to deal with this issue. The proposed techniques are essentially based on a statistical or dynamic approach or using machine learning or even deep learning. This paper discusses and reviews the existing techniques used to detect and prevent SQL injection attacks. In addition, it outlines challenges, open issues, and future trends of solutions in this context. https://www.isecure-journal.com/article_150514.html

Web applications are used by many users.web applications are consist of web forms, web server and backend. These applications are vulnerable due to attacks and scripts as the number of web application users are increasing. Web application can have sensitive and confidential data which is stored in database.web applications accepts the data from the users. This data is retrieved from the database through the queries.SQL Injection attack is one of the most popular attack used in system hacking or cracking. Using SQL INJECTION ATTACK attacker can gain information or have unauthorized access to the system. When attacker gains control over web application maximum damage is caused. This paper illustrates SQLIA methods and prevention and detection tools.

At present, Web applications have been used for most of our life activities increasingly, and they affected by Structured Query Language Injection Attacks (SQLIAs). This attack is a method that attackers employ to impose the database in most of the web applications, by manipulate SQL queries, which sent to the Relational Database Management System (RDBMS). Hence, change the behavior of the applications. In This paper, developing Web Application SQLI Protector (WASP) tool in real-time web application to detect SQL injection attacks in stored procedures. Then, evaluated and analyze the developed tool respect to efficiency and effectiveness in practices. The propose technique uses real-time based on positive tainting, accurate and efficiency taint propagation, and syntax aware evaluation of the query strings at the application level to detect illegal queries before they reach at the database by using Microsoft ASP.NET. The developed tool effective due to it capable of detect and stop all SQLI attacks in real-time environment and did not generate any false negative, a few-false positive values in the results and impose minimal deploy requirements.

Abstract—The Internet and web applications are playing very important role in our today‘s modern day life. Several activities of our daily life like browsing, online shopping and booking of travel tickets are becoming easier by the use of web applications. Most of the web applications use the database as a back-end to store critical information such as user credentials, financial and payment information, company statistics etc. An SQL injection attack targets web applications that are database-driven. This is done by including portions of SQL statements in a web form entry field in an attempt to get the website to pass a newly formed rogue SQL command to the database. Multiple client side and server side vulnerabilities like SQL injection and cross site scripting are discovered and exploited by malicious users. The principle of basic SQL injection is to take advantage of insecure code on a system connected to the internet in order to pass commands directly to a database and to then ...

SQL injection is one of the top threats to any web application which interacts with a database system. It is also one of the highly dangerous threats because it is easy to generate, difficult to design a defense mechanism and the data vulnerable to this type of attack is highly sensitive such as passwords, credit card details, etc. Injection attack is a method that can inject any kind of malicious string or anomaly string on the original string. The proposed algorithm shows that everything is well against the SQL Injection Attack. The Proposed a detection and prevention technique for data using Aho-Corasick pattern matching algorithm. This algorithm is classic algorithm. The results show that model protects against 100% of tested attacks before reaching the database layer.

Number of devices connected to internet are increasing day by day. Number of users for web applications is also increased rapidly. Most of the organization will have their website to give information to the users or to provide the service. Database is necessary to store data related to users or to store any information which users are served. SQL is used widely to communicate with the database. In SQL injection attack, malicious SQL statement is executed on the database by the attacker. SQL injection is very serious security threat as it can be employed to steal the content of database, change the values stored in the database, even whole database can be erased. In most of organizations content of database are very confidential and have financial importance for the organization. This review shows how the attack can be mitigated effectively.

SQL injection is a type of attack used to gain, manipulate, or delete information in any data-driven system regardless of whether the system is online or offline and whether this system is a web or non-web based. A common approach for an attacker to launch SQLIA is by modifying the user input to contain partial SQL queries and trick the server into executing them. In this paper, a literature review of the SQL injection attacks and their mitigation is presented. It shows that the study of SQL injection in general has been conducted in diverse range of areas. The main objective of this paper is to give an elaborate study on different types of SQL injection, their mitigation strategies, critiques of past approaches and finally the knowledge gap. It seeks to create knowledge on work done by others in the area of SQL injection attacks in web applications which remains a threat up-to-date despite the numerous studies done on the same field.

Structured Query Language (SQL) injection is an attack method used by hackers to retrieve, manipulate, fabricate or delete information in organizations’ relational databases through Web applications. Construction of secure software is not easy task, given the complexities that may be faced. SQL injection is increasingly exploiting the weaknesses of software year after year around the world. Security relevant issues in this area had not been properly addressed in relevant literatures during the development cycle of software. This paper conducts an approach called Centralized Dynamic Protection against SQL Injection Attacks in Web Applications (CDPIA) that creates a data type for checking system to prevent data type mismatch in dynamically generated SQL queries. To strengthen the approach, CDPIA utilizes encryption technique using Rivest, Shamir and Adleman (RSA) algorithm. The paper also discusses and presents most common Web application vulnerabilities with possible attack scenarios...

Data security has become a topic of primary discussion for security expert. Vulnerabilities are pervasive resulting in exposure of organizations and firms to a wide array of risks. Code Injection attack, a major concern for web security, occurs when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or when user input is not strongly typed and thereby unexpectedly executed, causing an error due to improper setup or coding such that the system fails to handle or properly respond to exceptional or unexpected data or conditions, which results in a situation wherein user credentials can be captured by injecting exceptional data. In spite of many tools and techniques, attacks on web application especially through SQL Injection Attacks are at a rise. Threat modeling is an important risk assessment and mitigation practice that provides the capability to secure a web application. A comprehensively designed threat model can provide a bet...
