A Structured Query Language injection is a type of cyber attack that results from inserting malicious code into a server that uses SQL queries to perform operations on data. The malicious code makes the web site or database view in question appear to run when the requested data is not actually available, and the attacker gains access to information stored there. SQL injection is a common attack vector used in web application attacks, because it’s very easy to exploit.

It can occur in a variety of ways:

• User input.
• Validation error.
• Exclusion rules.
• Injection vectors.

Incorrect storage

It’s important to note that SQL injection attacks are by definition unpredictable. They can even occur by accident. We have seen lots of applications and web sites that have been compromised in ways that couldn’t be predicted.

How are attacks detected? In general, detecting SQL injection attacks is a little more challenging than other types of web application attacks, because it’s difficult to tell when a specific injection has occurred. Many sites use a log format or else error reporting for detecting malicious SQL injection, but the location of the injected SQL can be difficult to determine. This lack of clarity can cause the attacker to slip past the alert/protection system and strike again, check this out to get more details.

How can you prevent SQL injection attacks? With the discovery of SQL injection attacks, an increasing number of companies have started implementing comprehensive logging and code auditing to detect and block SQL injection attacks. If you’re looking for an easy-to-implement technique to protect against SQL injection attacks, use your code auditing product to log, detect, and block SQL injections. The output from the checks and analyses should help ensure that the application is behaving in a consistent manner.
