SQL injection attacks pose a major threat to websites and databases. SQL injection is defined, explained, and prevented in this article. We’ll also use real-world examples and references to illustrate the issue’s gravity.

SQL Injection?

SQL injection lets hackers inject malicious SQL commands into databases through website input fields. This method can steal data, manipulate data, and take over a website.

How does SQL Injection work?

SQL injection exploits website input fields. A website’s form may request your username and password. This form checks the database for your username and password using SQL commands. SQL injection allows attackers to enter malicious SQL commands into form fields instead of a username and password. Consequently, the website will run the attacker’s SQL commands instead of the intended ones, giving the attacker database access.

SQL Injection Cases

RSA’s 2011 SQL injection attack is one of the famous among many. By injecting malicious SQL commands into a vulnerable website, the attackers stole RSA’s database data.

Target was attacked in 2013. Target’s database was injected with malicious SQL commands to steal 40 million customers’ credit card information.

Avoiding SQL Injection

User input should be validated and sanitized before running queries at the backed to prevent SQL injection. It is also a must for developers to incorporate security at all stages of software development lifecycle. Parameterized queries, escaping special characters, and input validation libraries accomplish this.

To patch security vulnerabilities, audit and update your website and database software.

SQL injection attacks are a major website security risk. Understanding how they work and preventing them can protect your website and users from this hacking technique. Be vigilant, proactive, and secure your website.
