SQL INJECTION ATTACKS AND PREVENTION TECHNIQUES

SQL injection attacks are a serious security threat to Web applications. They allow attackers to obtain unrestricted access to the databases underlying the applications and to the potentially sensitive information these database contain. Various resear chers have proposed various methods to address the SQL injection problem. To address this problem, we present an extensive review of the various types of SQL injection attacks. For each type of attack, we provide descriptions and examples of how attacks of that type could be performed. We also present a methodology to prevent the SQL injection attacks

Defensive Approaches on SQL Injection and Cross-Site Scripting Attacks

SQL Injection attacks are the most common attacks on the web applications Statistical analysis says that so many web sites which interact with the database are prone to SQL Injection XSS attacks Different kinds of vulnerability detection system and attack detection systems exist there is no efficient system for detecting these kinds of attacks SQL Injection attacks are possible due to the design drawbacks of the websites which interact with back-end databases Successful attacks may damage more The state-of-art web application input validation echniques fails to identify the proper SQL XSS Vulnerabilities accurately because of the systems correctness of sanity checking capability proper placement of valuators on the applications The systems fail while processing HTTP Parameter pollution attacks An extensive survey on the SQL Injection attacks is conducted to present various detection and prevension mechanism

Analysis of SQL Injection Detection Techniques

SQL Injection is one of the vulnerabilities in OWASPs Top Ten List for Web Based Application Exploitation.These types of attacks takes place on Dynamic Web applications as they interact with the databases for the various operations.Current Content Management System like Drupal, Joomla or Wordpress have all the information stored in their databases. A single intrusion into these types of websites can lead to overall control of websites by the attacker. Researchers are aware of the basic SQL Injection attacks but there are numerous SQL Injection attacks which are yet to be Prevented and Detected. Over here, we present the extensive review for the Advanced SQL Injection attack such as Fast Flux Sql Injection, Compounded SQL Injection and Deep Blind SQL Injection. We also analyze the detection and prevention using the classical methods as well as modern approaches. We will be discussing the Comparative Evaluation for prevention of SQL Injection

PachyRand: SQL Randomization for the PostgreSQL JDBC Driver

Many websites are driven by web applications that deliver dynamic content stored in SQL databases. Such systems take input directly from the client via HTML forms. Without proper input validation, these systems are vulnerable to SQL injection attacks. The predominant defense against such attacks is to implement better input validation. This strategy is unlikely to succeed on its own. A better approach is to protect systems against SQL injection automatically and not rely on manual supervision or testing strategies (which are incomplete by nature). SQL randomization is a technique that defeats SQL injection attacks by transforming the language of SQL statements in a web application such that an attacker needs to guess the transformation in order to successfully inject his code. We present PachyRand, an extension to the PostgreSQL JDBC driver that performs SQL randomization. Our system is easily portable to most other JDBC drivers, has a small performance impact, and makes SQL injection attacks infeasible

A Discriminative Survey on SQL Injection Methods to Detect Vulnerabilities in Web applications

SQL Injection Attacks are extremely sober intrusion assaults on web based application since such types of assaults could reveals the secrets and safety of information. In actuality, illegal personnel intrude to the web based database and then after consequently, access to the information. To avoid such type of assault different methods are recommended by various researchers but they are not adequate since most of implemented methods will not prevent all type of assaults. In this paper we did survey on the various sorts of SQL Injection attacks and on the various present SQL Injection Attacks avoidance methods available. We analyzed that the existing SQL Injection Attacks avoidance methods will require the client side information, one by one and then authenticate which will create typical the developer’s job to write different validation codes for every web page which is receiving in the server side.

Integration of SQL injection prevention methods

In everybody’s life including the organisations, database plays a very important role, since today everything is connected via the Internet. There is a need for a database that helps organisations to organise, sort and manage the data and ensure that the data a user receives and sends via the database mean is secure, since the database stores almost everything such as banking details including user ID and password. Make this data really valuable and confidential for us and therefore security is really important for the database. In this age, SQL Injection database attacks are increasingly common. The hackers attempt to steal an individual’s valuable data through the SQL Injection Attack mean by using malicious query on the application, hence revealing an efficient individual data. Therefore the best SQL Injection Prevention technique is needed to safeguard individual data against hackers being stolen. This paper compares two types of SQL Injection using the SQL pattern matching database system attack (SQLPMDS) and a SQL injection union query attacks prevention using tokenisation technique (SIUQAPTT) that allows Database Administrator to select the best and most effective SQL Injection Prevention method for their organisation. Preventing SQL Injection Attack from occurring that would ultimately lead to no user data loss. The results were obtained by comparing it to the results of the SQL injection attack query on whether the attack was blocked or not by two prevention techniques, SQL pattern matching database system attacks and SQL injecting union query attacks prevention using website tokenisation techniques. The conclusion is that the best method of prevention is the SQL pattern that matches database system attacks

Analysis of protection capabilities against SQL Injection attacks

Publication refers to SQL Injection attacks whose are one of the most dangerous in a cyberspace. Based on a literature studies, classification of the SQL Injection attacks was prepared. The purpose of the work was to analyse of protections effectiveness against SQL Injection attacks. Research method has been based on author application, which was implemented in JSP (JavaServer Pages) technology using MySQL database server

Analysis of SQL Injection Attacks on Website Service

Among the various types of software vulnerabilities, command injection is the most common type of threat in web applications. In command injection, SQL injection type of attacks areextremely prevalent, and ranked as the second most common form of attack on web. SQL injection attacks involve the construction of application\u27s input data that will result in the execution of Malicious SQL statements. Most of the SQL injection detection techniques involve the code to be written along with the actual scripting code. These techniques do not detect errors in SQL statements. Hence, this paper proposes a mechanism to identify invalid SQL statements, to analyze the query for invalid non SQL key words, and to customize the captured errors. This mechanism is different from others by means of separation of the main scripting code and SQL injection code

Review of SQL injection : problems and prevention

SQL injection happened in electronic records in database and it is still exist even after two decades since it first happened. Most of the web-based applications are still vulnerable to the SQL injection attacks. Although technology had improved a lot during these past years, but, hackers still can find holes to perform the SQL injection. There are many methods for this SQL injection to be performed by the hackers and there is also plenty of prevention for the SQL injection to be happened. The vulnerability to SQL injection is very big and this is definitely a huge threat to the web based application as the hackers can easily hacked their system and obtains any data and information that they wanted anytime and anywhere. This paper can conclude that several proposed techniques from existing journal papers used for preventing SQL injection. Then, it comes out with Blockchain concept to prevent SQL injection attacks on database management system (DBMS) via IP
