1. Use A Firewall

Do you want to boost the safety of your WordPress website? We highly recommend that you install a firewall. A firewall is a network security system that monitors and regulates incoming data to your site. It serves as an extra layer of protection against SQL injection attacks. 

Many WordPress website security solutions are equipped with a firewall, automatic Secure Sockets Layer (SSL) installation, and access to the Cloudflare Content Delivery Network (CDN) to ensure the website stays secure.

2. Limit Access Privileges

The best and most effective way to secure your databases against SQL Injection In WordPress is by limiting access privileges. Improper access privileges can quickly make your WordPress site vulnerable to such attacks. To keep your site safe, it’s essential to adjust your WordPress User Roles by limiting the access and alteration permissions of others. For instance, you can eliminate potential exposures by ensuring past users have been removed from non-subscriber roles, such as editor or contributor.

Hackers can gain access to sensitive information through database error messages, and you must be aware of this fact as soon as possible. It could include confidential details like authentication credentials, email addresses of server administrators, and portions of your internal code. To safeguard your website, it’s recommended to generate generic error messages on a customized HTML page. By limiting the amount of information disclosed, you can enhance the security of your WordPress site.

4. Validate Inputs And Filter User Data

Preventing SQL Injection In WordPress attacks on your website is crucial, and one of the most common ways hackers infiltrate is through user-submitted data. If you want to avoid this?

5. Prevent Dynamic SQL

Do you wish to ensure the safety of your WordPress website? It is advisable to avoid using dynamic SQL as it presents a security vulnerability. Dynamic SQL automatically generates and executes statements, providing openings for hackers. Instead, use prepared statements, parameterized queries, or stored procedures, which are more secure in safeguarding against SQL injection attacks.

Regardless of the solution you choose, it can be a useful tool in identifying and addressing any database-related problems.
