Securing your WordPress site against brute force attacks
A brute force attack is a common method of trying to access a WordPress site. It's a computer attack that consists of trying every possible combination of passwords until the right one is found. These attacks can have devastating effects, including unauthorized access to your site, deletion of content, or injection of malicious code. It is therefore essential to secure your WordPress site against this type of attack.
This introduction will guide you through several fundamental steps to secure your WordPress site against brute force attacks. We'll cover topics such as choosing a strong password, using a WordPress security plugin, limiting login attempts and enabling two-factor authentication. Each step is designed to increase the security level of your WordPress site and reduce the likelihood of a successful attack.

Understanding Brute Force Attacks
Brute-force attacks are a recurring threat to all websites, and WordPress is not exempt from this risk. It's an attack technique that involves trying every possible combination of passwords until you find the one that's being used. It's a process that can be time-consuming and resource-intensive, but with the advent of fast, powerful computers, it's become a reality we all have to face.
A notable example of such an attack took place in 2013, when thousands of WordPress sites were v
ictims of brute force attacks. The attackers used botnets - networks of infected computers - to launch their attacks, trying out millions of password combinations in a matter of minutes. The attack was a wake-up call for many site owners, underlining the need to take steps to secure their sites.
Using strong passwords
The first line of defense against brute-force attacks is to use strong passwords. A strong password is usually long, complex and unique. It should contain a combination of upper and lower case letters, numbers and special characters. It is also recommended not to use common words, proper nouns or important dates, as these can be easily guessed by attackers.
WordPress has made efforts to encourage the use of strong passwords. For example, when a new user account is created, WordPress automatically generates a strong password and encourages the user to use it. In addition, WordPress has introduced a feature that allows administrators to force users to reset their passwords if they are deemed too weak.
Limiting Connection Attempts
Another effective technique for preventing brute force attacks is to limit the number of failed login attempts allowed. After a certain number of unsuccessful attempts, access to the WordPress administration interface can be blocked for a set period of time.
There are several WordPress plugins that offer this functionality. One of the most popular is "Limit Login Attempts". This plugin lets you set the maximum number of login attempts allowed, and the duration of the block after that number is reached.
Setting up two-factor authentication
Two-factor authentication (2FA) is another security measure that can help protect your WordPress site against brute-force attacks. With 2FA, a user must provide two forms of identification to log in: something they know (like a password) and something they have (like a code sent to their phone).
There are several WordPress plugins that enable two-factor authentication. "Google Authenticator" and "Two Factor Authentication" are two examples of such plugins. They offer an extra layer of security by making it more difficult for an attacker to log in, even if they manage to guess your password.
Image Optimization for WordPress
In addition to securing your WordPress site against malicious
hen it comes to brute-force attacks, it's also important to optimize your site's performance. An often overlooked aspect of performance optimization is image management. Unoptimized images can slow down your site considerably, which can have a negative impact on your site's user experience and SEO.
Fortunately, there are several techniques and tools you can use to optimize your images for WordPress. To find out more on this subject, I invite you to consult this excellent guide on how to optimize images for WordPress.
Conclusion
The security of your WordPress site should be a priority. By taking steps to protect your site against brute-force attacks, such as using strong passwords, limiting login attempts and implementing two-factor authentication, you can greatly reduce the risk of falling victim to such an attack.
And don't forget that site security isn't just about preventing attacks. It's also important to optimize your site's performance, for example by optimizing your images for WordPress. By doing so, you can offer your users a better experience and improve your site's SEO.
1. Use a security plugin
Installing a WordPress security plugin such as Wordfence, iThemes Security or Sucuri can help secure your site against brute-force attacks. These plugins offer features such as limiting the number of connection attempts, blocking suspicious IP addresses and real-time monitoring of suspicious activity.
2. Activate two-factor authentication
Two-factor authentication (2FA) adds an extra layer of security by requiring not only a password, but also additional proof of identity, such as a code sent to your phone. The Google Authenticator plugin for WordPress is a great option for enabling 2FA.
3. Limit the number of connection attempts
Limiting the number of login attempts can help protect your site against brute-force attacks. After a certain number of failed login attempts, the user is temporarily blocked. This can be achieved using plugins such as Login LockDown or WP Limit Login Attempts.
4. Choose strong passwords
A strong, unique password is the first line of defense against brute-force attacks. Be sure to use a mix of letters, numbers and symbols to make your password difficult to guess.
5. Change your password regularly
We recommend changing your password regularly to reduce the chances of a successful attack. You can set a reminder to change your password every 3 to 6 months.
6. Use e-mail address for login
By default, WordPress allows users to log in using either their username or their e-mail address. By choosing to use only the e-mail address for login, you can make brute force attempts more difficult, as e-mail addresses are generally harder to guess than usernames.
7. Change login page URL
Changing the URL of your default login page (wp-login.php) can help protect your site against brute-force attacks. Many WordPress security plugins offer this feature.
8. Update your site regularly
Make sure your WordPress site, including all plugins and themes, is always up to date. Updates often contain security patches that can help protect your site against brute-force attacks.
9. Use a firewall
A firewall, whether built into a security plugin or provided by your hosting provider, can help block suspicious connection attempts before they reach your site.
