What is the difference between SQL Injection and XSS?

SQL Injection (SQLi) is a code injection technique that exploits vulnerabilities in an application's software by manipulating SQL queries. XSS (Cross-Site Scripting), on the other hand, allows attackers to inject malicious scripts into web pages viewed by other users.

Can you give me examples of each?

Sure! An example of SQL Injection is when an attacker inputs a malicious SQL statement into a login form to bypass authentication. For XSS, an example would be an attacker injecting a script into a comment section that runs when other users view the comment.

How can I protect my website from these attacks?

To protect against SQL Injection, use prepared statements and parameterized queries. For XSS, validate and sanitize user inputs, and use Content Security Policy (CSP) headers.

Are there any tools to test for these vulnerabilities?

Yes, tools like SQLMap for SQL Injection and OWASP ZAP for XSS testing can help identify vulnerabilities in your applications.
