What is SQL injection? It’s a cyberattack that exploits vulnerabilities in your website’s database queries, allowing hackers to modify, steal, or delete data—or even take full control of your site. SQL (Structured Query Language) is used to manage and retrieve information in relational databases, and poorly protected forms or fields can be entry points for malicious code.
How does SQL injection work?
Attackers insert malicious SQL code into input fields (like login forms) to manipulate your database. For example, a hacker might use a form to inject code that reveals usernames and passwords or deletes important data. If successful, they can access confidential information or disrupt your business.
If hackers get in, they can manipulate all your stored information, including sensitive data like credit card numbers or business records.
How to prevent SQL injection
- Regularly update your website and plugins (especially if you use WordPress).
- Use strong, unique passwords for all databases and change them often.
- Install security plugins like Wordfence to scan for vulnerabilities.
- Protect critical files (like .htaccess and wp-config.php) and restrict access to sensitive folders.
- Always back up your data and keep your software up to date.
Conclusion
SQL injection is a common but preventable threat. Secure your website with regular maintenance, strong passwords, and professional help if needed—your business’s security depends on it.
