Keeping WordPress Core, Themes, and Plugins Updated
WordPress updates play a crucial role in patching vulnerabilities that hackers often exploit. Since WordPress is open source, attackers can analyze the code to pinpoint weaknesses. When these vulnerabilities are identified, the WordPress team releases updates to address them – but these fixes only protect your site if you install them. In fact, around 80% of WordPress vulnerabilities stem from the core software, while plugins account for 17% [7]. Keeping your site updated is essential for security. Here’s how you can ensure your site stays protected.
"If you’re not running the latest version of WordPress, your site could be exposed to known vulnerabilities. Hackers often target outdated websites, increasing the risk of an attack." – WPBeginner [5]
Risks of Running Outdated Software
Running outdated WordPress software leaves your site exposed to potential attacks. When a security flaw is discovered, the details are often made public, giving hackers a clear path to exploit it. Even inactive plugins or themes can pose risks. For example, in May 2023, WordPress released version 6.2.1 to address 20 bugs and security issues, including a directory traversal vulnerability linked to translation files in the 6.2 release [5][8].
But it’s not just about security. Outdated components can lead to compatibility issues, causing parts of your site to break. Updates also include performance boosts and bug fixes, meaning neglecting them could make your site slower and less stable.
How to Update WordPress Components Safely
Understanding the risks of outdated software underscores the importance of a secure update process.
WordPress categorizes updates into two types: minor updates (focused on security and bug fixes) and major updates (introducing new features). Since version 3.7, WordPress has automatically applied minor and security updates [9][6]. Major updates, however, usually require manual action – clicking "Update Now" in your dashboard – though you can configure automation if desired.
To update safely:
- Back up your site: Always create a full backup before making any updates.
- Update in order: Start with the WordPress core, then move to plugins, and finally themes [10].
- Test functionality: After updating, clear your site cache and check that everything works as expected.
For automatic updates, you can modify your wp-config.php file by adding this line:
define('WP_AUTO_UPDATE_CORE', true); To enable automatic updates for plugins and themes, add the following filters to your functions.php file:
add_filter('auto_update_plugin', '__return_true'); add_filter('auto_update_theme', '__return_true'); The WordPress security team has occasionally pushed emergency updates. For instance, in April 2014, they automatically updated all installations of the JetPack plugin to fix a critical vulnerability [6].
| Update Type | Frequency | Automatic by Default? | Primary Purpose |
|---|---|---|---|
| Minor Release | As needed | Yes (since v3.7) | Security patches and bug fixes |
| Major Release | ~2–3 times/year | No (manual) | New features and performance |
| Plugin/Theme | Varies by developer | Optional (can enable) | Features, compatibility, security |
Lastly, remove unused plugins and themes entirely to minimize vulnerabilities [1]. Regularly check your WordPress dashboard for pending updates, and if an update fails, delete the .maintenance file from your root directory to resolve the issue [9][11].
Strengthening Login Security
Your WordPress login page is a frequent target for attacks. In fact, up to 80% of breaches result from weak or stolen passwords [17]. Automated scripts can quickly try a massive number of login combinations [16], making it essential to take proactive steps to secure your site.
Using Strong Passwords
Creating a strong password is one of the simplest yet most effective ways to protect your WordPress account. Aim for a password that’s 20–24 characters long, combining uppercase and lowercase letters, numbers, and symbols. This makes it exponentially harder for anyone to crack [12].
"A strong password is complex and elaborate. It isn’t easy to guess since it doesn’t contain recognizable words, names, dates or numbers." – WordPress.org Documentation [12]
Avoid common, easy-to-guess passwords like "123456", "qwerty", or "password." These remain some of the most vulnerable choices in 2024 [13]. Also, never reuse passwords across multiple accounts. Hackers often use a technique called credential stuffing, where they test a cracked password across other platforms to gain access.
WordPress includes a built-in password generator that creates secure, randomized 24-character strings. Use it whenever you’re creating a new account. To manage multiple complex passwords, consider using tools like LastPass, 1Password, or Bitwarden.
Another key step is to avoid default usernames like "admin." Instead, create a unique administrator account and, for added privacy, set a Nickname to display publicly instead of your username.
Setting Up Two-Factor Authentication (2FA)
Even the strongest passwords can benefit from an extra layer of security. Two-factor authentication (2FA) adds a second step to the login process, requiring a verification code in addition to your password. This means that even if someone gets your password, they can’t log in without the second code.
To enable 2FA, install a plugin like WP 2FA or Two-Factor [14]. Once installed, link it to an authenticator app such as Google Authenticator, Authy, Microsoft Authenticator, or 1Password. The setup process is straightforward: scan the QR code displayed on your WordPress screen with the app, then enter the six-digit code it generates to complete the connection. Be sure to save your backup codes – these one-time-use codes are your lifeline if you lose access to your primary device.
If you manage a team, it’s a good idea to require 2FA for all users or at least for high-level roles like Administrators and Editors. You can even set a grace period to give everyone time to configure their devices.
"A successful attack can give hackers access to your admin area, where they can install malware, steal user information, or delete your entire site." If you suspect your site has already been compromised, follow a hack recovery guide to restore security. – WPBeginner [15]
Blocking Brute Force Attacks
Passwords and 2FA are essential, but they’re not enough to stop automated brute force attacks. By default, WordPress allows unlimited login attempts, which makes it easy for bots to keep guessing passwords until they succeed [16]. Even failed login attempts can slow down your server due to the extra load [18].
To combat this, install the "Limit Login Attempts Reloaded" plugin. Configure it to block an IP address after four failed login attempts, locking them out for 20 minutes. This simple plugin is free and can be set up in just a few minutes.
For additional security, you can hide your login URL. The "WPS Hide Login" plugin lets you change the default /wp-login.php path to a custom URL [17], making it harder for bots to find your login page.
If you’re using a DNS-level firewall like Sucuri or Cloudflare, you’re already filtering out malicious traffic before it even reaches your server [3]. These firewalls are highly effective at blocking brute force attempts at the proxy level.
Finally, disable XML-RPC via your .htaccess file if you don’t use mobile apps or remote posting. This eliminates a common attack vector [3].
Taking these steps will significantly strengthen your login security and set the stage for more advanced measures in the next section.
Securing Data with SSL/TLS Certificates
After fortifying your login security, the next crucial step is encrypting the data exchanged between your site and its visitors. Without encryption, sensitive information like passwords, credit card details, and personal data can travel unprotected, leaving it vulnerable to cyberattacks.
Why SSL/TLS Is Important
SSL (Secure Sockets Layer) and its modern counterpart, TLS (Transport Layer Security), create a secure channel between a user’s browser and your web server. This encryption ensures that data is scrambled, making it unreadable to hackers attempting Man-in-the-Middle (MITM) attacks [19].
"HTTPS is not just a best practice; it’s an essential requirement in today’s digital world." – Nathan Orr, Content Writer, CreativeMinds [19]
Beyond safeguarding data, SSL certificates also establish trust. When your site uses HTTPS, browsers display a padlock icon in the address bar. Without it, browsers like Chrome label your site as "Not Secure", which can deter visitors instantly [21]. Google even prioritizes HTTPS-enabled sites in search rankings, giving secure websites an edge [20]. For e-commerce platforms, SSL is non-negotiable, as it’s required for compliance with standards like PCI DSS and GDPR [19].
Consider this: Google blacklists around 10,000 websites daily for malware or phishing [3], and issues warnings to 12–14 million users about risky sites every day [3]. Meanwhile, the average global cost of a data breach is a staggering $3.86 million [19]. Installing SSL isn’t just a good idea – it’s a necessity.
Let’s dive into how you can install and configure SSL for your website.
Installing an SSL Certificate
Many hosting providers, such as Bluehost, SiteGround, Hostinger, and DreamHost, include free SSL certificates through Let’s Encrypt in their plans [21]. To enable it, check your hosting control panel (like cPanel or a custom dashboard) for a "Let’s Encrypt" or "AutoSSL" option, and activate it with just one click [21]. These free certificates are perfect for blogs or smaller sites [20]. However, for e-commerce platforms or sites requiring enhanced security, premium certificates from providers like Sectigo or DigiCert are available. These typically cost $50–$200 per year and come with extended validation (EV) and added security warranties [21].
Once your SSL certificate is installed, follow these steps to finalize the setup:
- Go to Settings > General in your website dashboard and update both the "WordPress Address (URL)" and "Site Address (URL)" from
http://tohttps://[20]. - Add the following code to your
.htaccessfile to redirect all traffic to the secure version of your site [20]:
<IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{HTTPS} off RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301] </IfModule> - If you encounter a "mixed content" warning (where some elements still load over HTTP), use a plugin like Really Simple SSL to detect and fix these issues automatically [20].
- Test your setup with Qualys SSL Labs to ensure your certificate is correctly installed and to identify any missing chain certificates [20].
- Add the HTTPS version of your site as a new property in Google Search Console to preserve your SEO rankings [22].
Fixing Common Coding Vulnerabilities
Securing your site goes beyond strong passwords and SSL certificates. If your code has flaws, it can still leave your site open to attacks. Two major threats to watch out for are SQL injection and cross-site scripting (XSS). These vulnerabilities are especially common in WordPress plugins. In fact, SQL injection ranks as the second most frequent issue in plugins [25], while XSS tops the list as the most common hacking method for WordPress sites [29]. Wordfence reports that addressing just these two vulnerabilities can eliminate about 65% of accidental security risks in WordPress development [25].
Preventing SQL Injection Attacks
SQL injection (SQLi) happens when attackers insert malicious code into database queries through input fields like login forms, search bars, or contact forms [23][27]. If raw user input is directly added to SQL queries without proper sanitization, attackers can gain control of your database. This can lead to unauthorized access, data theft, account takeovers, or even denial-of-service attacks. In 2021 alone, SQL injection accounted for 9.3% of all WordPress security threats [23].
To prevent SQL injection, always prioritize WordPress’s built-in functions.
"The first rule for hardening your theme against SQL injection is: When there’s a WordPress function, use it." – WordPress Developer Resources [24]
Instead of writing manual SQL queries, use WordPress API functions like add_post_meta() or wp_update_post() [24]. If custom queries are unavoidable, make sure to use $wpdb->prepare() with placeholders for different data types:
| Placeholder | Data Type | Usage Example |
|---|---|---|
%s |
String | $wpdb->prepare("... WHERE name = %s", $user_name) |
%d |
Integer | $wpdb->prepare("... WHERE ID = %d", $user_id) |
%f |
Float | $wpdb->prepare("... WHERE price = %f", $price) |
Additionally, sanitize all user inputs before processing. Use functions like sanitize_text_field() for plain text, sanitize_email() for email addresses, and absint() for integers [23][28]. On the server side, limit your MySQL user’s permissions to only what’s necessary – such as SELECT, INSERT, UPDATE, and DELETE – while disabling privileges like DROP or GRANT [4].
Once your queries are secured, don’t forget to safeguard any dynamic outputs as well.
Stopping Cross-Site Scripting (XSS) Attacks
XSS attacks work by injecting malicious JavaScript into your site, which can lead to stolen data, hijacked sessions, or even site defacement [29][24]. There are three main types of XSS:
- Persistent (Stored) XSS: Malicious scripts are saved in your database, often through fields like comments.
- Reflected XSS: Scripts are immediately executed via URL parameters.
- DOM-based XSS: Client-side code is directly manipulated.
These attacks are alarmingly common. Google warns between 12 and 14 million users daily about sites containing malware or phishing attempts, and over 10,000 websites are blacklisted every day [3]. XSS vulnerabilities are a significant contributor to these numbers.
"Cross-site scripting (XSS) is a type of malware attack that’s executed by exploiting cross-site vulnerabilities on any WordPress site. In fact, it’s the most common way for WordPress sites to be hacked because there are so many WordPress plugins that have XSS vulnerabilities." – SolidWP Editorial Team [29]
The solution? Escape all dynamic outputs. WordPress provides several context-specific functions to help:
| Function | Use Case | Example |
|---|---|---|
esc_html() |
Text inside HTML tags | <td><?php echo esc_html($name); ?></td> |
esc_attr() |
Data in HTML attributes | <div class="<?php echo esc_attr($class); ?>"> |
esc_url() |
URLs in href or src attributes | <img src="<?php echo esc_url($url); ?>"> |
wp_kses() |
HTML content with allowed tags | echo wp_kses($content, $allowed_html); |
For content that requires some HTML, wp_kses() lets you define which tags are allowed and strips out the rest [24][30].
To further strengthen your defense, implement Content Security Policy (CSP) headers to control which scripts can run on your site [29]. Using one of the best WordPress security plugins to add a Web Application Firewall (WAF), such as Sucuri, can block malicious requests before they hit your server [23]. Lastly, use nonces with wp_create_nonce() and wp_verify_nonce() to safeguard against Cross-Site Request Forgery (CSRF) attacks and ensure form submissions are legitimate [26][28].
Advanced WordPress Security Measures
After addressing coding vulnerabilities, the next step is securing your WordPress infrastructure. These steps go beyond the basics, adding extra layers of protection to make it much harder for attackers to exploit your site.
Setting Correct File Permissions
File permissions dictate who can read, write, or execute files on your server. Following the Principle of Least Privilege, you should only grant the minimum level of access needed for WordPress to function. Here’s a quick guide to the recommended settings:
| File/Directory | Permission | Description |
|---|---|---|
| All Directories | 755 | Owner: read/write/execute; others: read/execute |
| All Files | 644 | Owner: read/write; others: read |
| wp-config.php | 400 or 440 | Restricts access to sensitive data |
| .htaccess | 644 or 600 | Protects server configuration |
Avoid using 777 permissions, as they allow unrestricted access, which poses a serious security risk. Keep in mind that 41% of WordPress vulnerabilities are linked to hosting platform issues [2].
To adjust permissions, navigate to your WordPress directory and run the following commands:
- For directories:
find /path/to/wordpress/ -type d -exec chmod 755 {} \; - For files:
find /path/to/wordpress/ -type f -exec chmod 644 {} \;
Additionally, manually set wp-config.php to 400 or 440 for added security. Most hosting platforms, such as cPanel or Plesk, also let you adjust permissions through their file managers.
For extra protection, you can disable directory browsing by adding this line to your .htaccess file:
Options -Indexes "Security is not about perfectly secure systems… What security is though is risk reduction, not risk elimination." – WordPress Developer Resources [4]
While securing file permissions is critical, reducing the potential for code manipulation is equally important.
Disabling File Editing in WordPress
WordPress comes with a built-in editor in the Dashboard, allowing administrators to modify PHP files for themes and plugins. While convenient, this feature can become a security liability. If an attacker gains admin access, the editor can be used to inject malicious code. Even accidental errors in the editor can break your site, leading to the dreaded "White Screen of Death" that often requires FTP access to fix [4][31].
"This is often the first tool an attacker will use if able to login, since it allows code execution." – WordPress Developer Resources [4]
To disable this feature, open your wp-config.php file (found in the WordPress root directory) and add the following line before the comment that says, "/* That’s all, stop editing! Happy publishing. */":
define( 'DISALLOW_FILE_EDIT', true ); This disables file editing for all users, including administrators. After making this change, use SFTP for any theme or plugin modifications to enhance security. If manual editing feels daunting, security plugins like Sucuri (starting at $199/year) or iThemes Security can disable the editor with a single click [3].
Disabling the editor reduces the risk of unauthorized code changes and helps maintain your site’s stability.
Tracking User Activity with Logs
Monitoring user activity is another essential layer of security. Activity logs provide a detailed record of actions on your site, helping you detect suspicious behavior – like unauthorized logins, unexpected file changes, or privilege escalations – before they escalate into major issues.
"Logs are your best friend when it comes to understanding what is happening with your website, especially if you’re trying to perform forensics." – WordPress Developer Resources [4]
A good logging tool should track key events, including:
- Successful and failed login attempts
- User account creation or deletion
- File uploads
- Changes to plugins, themes, or widgets
Set up real-time email alerts for high-risk actions, such as new administrator registrations or modifications to core configuration files. This allows you to respond quickly to potential threats. Analyze your logs for patterns, like repeated failed login attempts, which could indicate a brute force attack. If you spot suspicious IP addresses, block them using your firewall or security plugin.
Several plugins can help with activity monitoring. Sucuri Security (approximately $199/year) includes audit logs and file integrity monitoring [3], while Wordfence Security offers malware scanning and login tracking [32]. For those with root server access, OSSEC is an open-source option that provides log analysis and real-time alerts [4]. Additionally, enabling automatic logout for inactive users can prevent session hijacking [3].
Conclusion and Next Steps
Keeping your WordPress site secure is an ongoing effort that requires consistent vigilance. The vulnerabilities covered in this guide – such as outdated software, weak passwords, and improper file permissions – are among the most common ways hackers gain access. Addressing these issues can go a long way in reducing your risk. As the WordPress Developer Documentation aptly states, "Security is not about perfectly secure systems. Such a thing might be impractical or impossible to maintain. What security is, though, is risk reduction – not risk elimination." [4]
The numbers highlight the urgency: 95.5% of all CMS infections in 2023 happened on WordPress sites, and 39.1% of those hacked were running outdated versions at the time [33]. The good news? Most of these breaches are preventable. Simple actions like enabling automatic updates, using strong passwords combined with Two-Factor Authentication (2FA), installing an SSL certificate, and disabling the dashboard file editor can significantly strengthen your defenses. It’s always cheaper and less stressful to prevent problems than to fix them after the fact.
A layered approach is key to building a more secure site. Start by updating your WordPress core, plugins, and themes. Add 2FA for login protection, install an SSL certificate to encrypt data, and set proper file permissions (755 for directories, 644 for files). Monitoring user activity and maintaining activity logs are other critical steps. These layers of protection work together to create a much stronger barrier against potential attacks.

FAQs
How can I set up automatic updates to keep my WordPress site secure?
To keep your WordPress site automatically updated, here’s what you need to do:
- Enable background updates: WordPress typically handles minor core, plugin, and theme updates on its own. Just double-check that this feature hasn’t been turned off in your
wp-config.phpfile or by a plugin. - Allow major updates: Add this line of code to your
wp-config.phpfile:define( 'WP_AUTO_UPDATE_CORE', true );. This ensures WordPress will also take care of major updates automatically. - Review your dashboard settings: Head over to Dashboard → Updates to verify that automatic updates are active for your site’s core, plugins, and themes.
- Leverage a management tool: Consider using tools recommended by WP Winners. These can handle updates and backups for you, offering a hassle-free way to keep your site secure and up to date.
With automatic updates in place, your site will benefit from the latest security fixes and enhancements – all without you lifting a finger.
What are the best ways to create strong passwords for WordPress?
Creating strong passwords is one of the easiest ways to enhance the security of your WordPress site. A good password acts as a strong barrier, making it harder for anyone to gain unauthorized access.
Here’s how you can create a secure password:
- Go long: Aim for at least 20 characters to make it harder to crack.
- Mix things up: Combine uppercase and lowercase letters, numbers, and symbols like
@,#, or!. - Avoid the obvious: Steer clear of predictable choices like names, birthdays, or common words.
- Keep it one-of-a-kind: Never reuse the same password for multiple accounts.
To make managing passwords easier, think about using a reliable password manager. These tools can generate and securely store complex passwords, simplifying your WordPress security efforts. WP Winners also offers great resources to help you strengthen your password practices.
Why should I use an SSL/TLS certificate on my WordPress site?
Using an SSL/TLS certificate is a key step in keeping your WordPress site and its visitors safe. By encrypting the data exchanged between your site and its users, it protects sensitive details like passwords and personal information from prying eyes.
But security isn’t the only benefit. Having an SSL/TLS certificate also helps you gain your audience’s trust. That little padlock in the browser bar reassures visitors that your site is secure. Plus, search engines like Google tend to favor secure websites, which can give your site’s rankings a helpful boost.
Securing your site with SSL/TLS is a straightforward but vital move to ensure user trust and maintain strong website performance.
