What is WordPress Site Security

WordPress Site Security refers to the measures and practices implemented to protect WordPress websites from various cyber threats, vulnerabilities, and unauthorized access. As the most widely used content management system (CMS) on the internet, WordPress is a prime target for hackers and malicious actors. Therefore, website owners and administrators need to prioritize security to ensure the safety of their data, users, and online reputation.

You cannot overlook the significance of WordPress Site Security; a compromised website can lead to severe consequences, such as data breaches, loss of sensitive information, defacement, malware infections, and even blocking your WordPress site by search engines. As a result, website owners must adopt a proactive approach to prevent potential attacks and vulnerabilities.

Common WordPress Vulnerabilities that Need to Be Addressed

  • Outdated Core, Themes, and Plugins: Please regularly update WordPress core files, themes, and plugins to avoid known vulnerabilities.
  • Weak Passwords and User Authentication: Using weak passwords or not enforcing strong password policies for users can make it easier for attackers to gain unauthorized access.
  • Lack of Two-Factor Authentication (2FA): 2FA provides an additional layer of security by requiring users to provide two forms of identification before accessing the website.
  • Insecure Hosting Environments: Choosing an unreliable hosting provider can expose the website to security risks, making it crucial to opt for reputable hosts.
  • File Permission Issues: Incorrect file permissions might allow unauthorized users to modify critical files and gain control over the website.
  • Cross-Site Scripting (XSS) Attacks: XSS vulnerabilities enable attackers to inject malicious scripts into web pages viewed by other users.
  • SQL Injection (SQLi) Vulnerabilities: SQLi exploits weaknesses in a website’s database, allowing attackers to access, modify, or delete data.

To enhance WordPress Security, website owners should follow these best practices:

  • Keep Everything Updated Regularly: Ensure that WordPress core, themes, and plugins are up to date. Remove unused themes and plugins to reduce the potential attack surface.
  • Strengthen User Authentication: Enforce strong password policies for all users. Consider implementing Two-Factor Authentication (2FA) for an additional layer of security.
  • Choosing a Secure Hosting Provider: Opt for a reputable hosting company that prioritizes security and offers HTTPS encryption.
  • Set Proper File Permissions: Restrict file permissions to minimize unauthorized access. Limit write permissions to essential directories.

Basic WordPress Site Security Tips

These essential security tips are simple yet highly effective measures that don’t require any coding expertise. Follow these recommendations to bolster your WordPress security:

Change the Initial “Admin” Administrator Username

Many users tend to keep the default “Admin” username, making it an easy target for hackers. To increase security, change your administrator username to something unique and avoid using common names. Additionally, incorporating capital letters in the username can add an extra layer of protection. Ensure you also update the username in your blog posts and pages.

Set a Strong Password

Avoid weak and easily guessable passwords like “123456,” “password,” or simple words and patterns. Instead, create a lengthy password (at least 15 characters) that is hard to guess. Combine alphabets, numbers, and symbols to make it more robust. Steer clear of using personal information in your password, such as your pet’s name or date of birth.

Choose Trustworthy Hosting Providers

It is crucial to select a reputable hosting company, as it is the first defence against potential website breaches. Opt for hosting providers that offer robust security features, such as 24/7 monitoring, firewall support, and the latest versions of MySQL, PHP, and Apache. Look for those implementing DDOS prevention measures and conducting regular malware scans and backups.

Keep WordPress Updated

Regularly update your WordPress dashboard to ensure the latest security patches are applied. According to the data, approximately 31.5% of the identified vulnerabilities in WordPress websites were through the core WordPress system. Keeping your WordPress installation up-to-date is a prudent step and crucial for ensuring your website’s overall health and proper functioning.

Keep Themes and Plugins Updated

Update your themes and plugins promptly whenever new versions are available. Updates introduce new features, address security vulnerabilities, and fix bugs. Outdated themes and plugins can become entry points for hackers, making it crucial to stay current with the latest versions. Contact developers if you encounter any issues during the update process.

Download Themes and Plugins from Authentic Sources Only

Avoid downloading themes and plugins from unknown or unverified websites. These sources might offer faked or nulled themes and plugins, many of which contain malware that can compromise your website’s security. Stick to downloading themes and plugins from WordPress.org search results or reputable developers’ websites.

Install a Firewall on Your Computer

Protect your computer from potential threats and suspicious activities by installing a reliable firewall. Safeguarding your computer will also safeguard your website, as hackers will find accessing sensitive information connected to your machine harder.

Use WordPress Site Security Plugins

Leverage WordPress security plugins designed to fortify your dashboard and website against potential hacking attempts. These plugins create an additional layer of defence, blocking malicious and malware traffic and reducing security risks significantly. Popular security plugins include All in One WP Security & Firewall, Wordfence, and Plugin Security.

Enable Security Scans

Enabling security scans through your plugins ensures your website’s safety. While these scans may take some time, they act as an antivirus for your website, identifying and removing suspicious activities—schedule scans regularly, with shorter intervals for increased effectiveness.

It is advisable to conduct monthly scans to check for potential vulnerabilities. However, if your hosting provider has a history of known vulnerabilities, it may be necessary to perform weekly or even daily scans to ensure the security of your website.

Avoid Using Nulled Themes and Plugins

Steer clear of using nulled WordPress themes and plugins, as they are modified versions of premium themes and plugins without copyright. These unauthorized versions often contain malware, posing significant risks to your website’s security. Invest in legitimate themes and plugins to maintain a secure and reliable website.

Ensure Regular Backups

Regularly backing up your website’s data is a fundamental precautionary measure. In case of any issues or breaches, having a backup allows you to restore your website to its previous state effortlessly. Numerous plugins available on WordPress.org, such as UpdraftPlus and Backup WordPress, can assist you in implementing reliable backup strategies.

Monitor Login History

Monitor your website’s login history to keep track of user activities on your dashboard. If you notice irregular login times or suspicious activities, promptly change your password and username. Monitoring login history is a simple yet effective way to audit your website’s security.

Technical Security Tips

These technical security tips involve default WordPress dashboard settings and may require some coding knowledge. While they might take a bit of time and effort to implement, they provide additional layers of security to your website:

Always Use Two-Factor Authentication for Login

Even with a strong password, using two-factor authentication adds an extra layer of security. This verification process during login can prevent hackers from gaining unauthorized access to your website. You can easily enable two-factor authentication by installing relevant plugins and connecting them to your email address.

Hide Your WordPress Update Version Number

Conceal your WordPress version number to prevent hackers from inspecting source codes to find potential vulnerabilities. Plugins or custom codes can help you hide this information effectively.

Automatically Log Out Idle Users

Leaving your user ID and password logged in on your browser can pose a significant security risk. Installing a plugin that automatically logs out idle users after a specific period will minimize the chances of unauthorized access to your dashboard.

Disable PHP Error Reports

Although PHP error reports can help identify website errors, they expose your server path to potential threats. Turn off PHP error reports by adding specific codes to your wp-config.php file to enhance security.

Use SSL and HTTPS

Implementing HTTPS and SSL on your website ensures a secure connection between your site and visitors’ browsers, encrypting the data exchanged. Additionally, it provides SEO benefits and improves your site’s credibility.

Customize Your Login URL

Changing the default login URL (yoursitename.com/wp-admin or yoursitename.com/wp-login.php) can thwart potential hackers who often target this common entry point. Security plugins are available to facilitate this change.

Disable Login Hints

Turn off any login hints that might reveal username information or passwords during login attempts. This measure makes it more challenging for hackers to crack login credentials. To turn off your login hint, insert it in the functions.php file.

function no_wordpress_errors(){

   return 'Access Denied';
}
add_filter( 'login_errors', 'no_wordpress_errors' );

Disable Trackbacks

Uncheck the “pingbacks and trackbacks” option in your dashboard’s Discussion settings. Trackbacks can offer some benefits; however, they also pose a risk of exploitation by hackers in DDoS attacks. As a security precaution, newer websites should turn off trackbacks to safeguard against potential threats.

Advanced Security Measures

While implementing essential security tips helps strengthen your WordPress website, taking additional advanced security measures is crucial for safeguarding against potential threats. 

Here are some technical WordPress site security tips that require a bit of coding knowledge but offer significant benefits:

Protect Your wp-config.php File

The wp-config.php file is a critical component of your WordPress installation, containing vital data about your website. Moving this file to a higher-level root directory makes it more challenging for hackers to access. This simple step adds an extra layer of protection to your core files.

Disable XML-RPC

XML-RPC is a protocol that facilitates communication between WordPress mobile applications and plugins. However, it also presents a potential opening for hackers to send malicious commands to your website. Disabling XML-RPC prevents this vulnerability. You can easily find plugins on WordPress.org that help you turn off XML-RPC functionality.

Disable WordPress Theme and Plugin Editing

In multi-user environments, other individuals may have access to your WordPress dashboard. Removing the ability to edit themes and plugins from within the dashboard grants you more control over your website’s settings. This way, you can avoid headaches resulting from accidental changes made by other users. Enter the following code at the end of your wp-config.php file.

// Disable file edit 
define('DISALLOW_FILE_EDIT', true);

Turn Off Directory Browsing

Blocking access to your directory files is crucial in protecting your website’s data and information. Unauthorized access to directories can lead to the insertion of malicious code, potentially compromising your website’s security. To turn off directory browsing, add specific code to your .htaccess file.

Limit Dashboard Accessibility

When multiple users have dashboard access, managing their permissions is essential. Administrators should maintain control over dashboard accessibility and classify user roles, clearly defining the extent of their privileges. Limiting dashboard access ensures better control over your website’s administration.

Limit Login Attempts

Prevent brute force attacks on your login page by limiting the number of failed login attempts. Implementing a restriction on failed login attempts adds an extra layer of security, minimizing the risk of unauthorized access to your account. Follow the example set by platforms like Facebook and Gmail, which limit login attempts to protect user accounts.
