SQL Injection Attacks and Defense by Justin Clarke

Winner of the Best Book Bejtlich Read in 2009 award!

SQL injection is probably the number one problem for any server-side application, and this book is unequaled in its coverage. Richard Bejtlich, http: //taosecurity.blogspot.com/

SQL injection represents one of the most dangerous and well-known, yet misunderstood, security vulnerabilities on the Internet, largely because there is no central repository of information to turn to for help. This is the only book devoted exclusively to this long-established but recently growing threat. It includes all the currently known information about these attacks and significant insight from its contributing team of SQL injection experts.

SQL Injection Attacks and Defense

SQL injection is a code injection technique, used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution e. SQL injection is mostly known as an attack vector for websites but can be used to attack any type of SQL database. SQL injection attacks allow attackers to spoof identity, tamper with existing data, cause repudiation issues such as voiding transactions or changing balances, allow the complete disclosure of all data on the system, destroy the data or make it otherwise unavailable, and become administrators of the database server. In a study, it was observed that the average web application received 4 attack campaigns per month, and retailers received twice as many attacks as other industries. The first public discussions of SQL injection started appearing around ; [3] for example, a article in Phrack Magazine. This classification represents the state of SQLI, respecting its evolution until —further refinement is underway.

Get Demo. Download Online Scan. These statements control a database server behind a web application. Attackers can use SQL Injection vulnerabilities to bypass application security measures. They can go around authentication and authorization of a web page or web application and retrieve the content of the entire SQL database.

SQL injection is currently the most common form of web site attack in that web forms are very common, often they are not coded properly and the hacking tools used to find weaknesses and take advantage of them are commonly available online.

What is SQL injection

SQL Injection Attack Tutorial (2019)

SQL injection is one of the most common web attack mechanisms utilized by attackers to steal sensitive data from organizations. This technique is made possible because of improper coding of vulnerable web applications. These flaws arise because entry fields made available for user input unexpectedly allow SQL statements to go through and query the database directly. Attackers are constantly probing the Internet at-large and campus web sites for SQL injection vulnerabilities. They use tools that automate the discovery of SQL injection flaws, and attempt to exploit SQL injection primarily for financial gain e. Because so many modern applications are data-driven and accessible via the web, SQL Injection vulnerabilities are widespread and easily exploited.

Learning Objectives. SQL injection, also known as SQLI, is a common attack vector that uses malicious SQL code for backend database manipulation to access information that was not intended to be displayed. This information may include any number of items, including sensitive company data, user lists or private customer details. The impact SQL injection can have on a business is far-reaching. A successful attack may result in the unauthorized viewing of user lists, the deletion of entire tables and, in certain cases, the attacker gaining administrative rights to a database, all of which are highly detrimental to a business. While this vector can be used to attack any SQL database, websites are the most frequent targets. SQL is a standardized language used to access and manipulate databases to build customizable data views for each user.

Your company's website does not have to be the next victim of a SQL injection breach. Here's how to prevent SQL injection attacks. Top Vulnerability Scanning Tools. SQL injection is a hacking technique that was discovered more than fifteen years ago and is still proving to be devastatingly effective today, remaining a top database security priority. It was used in the run-up to the U. In modern web development, these databases are often used on the back end of web applications and content management systems written in PHP, ASP. NET or other scripting languages — meaning that both the content and behavior of many websites is built on data in a database server.
