To effectively protect your WordPress website from malicious attacks, it’s crucial to implement strong security measures. Here’s a comprehensive guide to safeguarding your site:
#1. Keep Everything Updated
Keeping all components of your WordPress site up to date is vital for maintaining security:
a). WordPress Core
Ensure that your WordPress installation is always updated to the latest version. Each update often includes fixes for vulnerabilities and performance improvements.
b). Themes and Plugins
Regularly update your themes and plugins. Developers frequently release updates to patch security vulnerabilities and improve functionality. Outdated themes and plugins can be easy targets for hackers.
c). PHP Version
Update your PHP version to the latest stable release. Newer PHP versions come with improved performance and security features that help protect against various exploits.
#2. Use Strong Passwords and Two-Factor Authentication
Implementing strong passwords and two-factor authentication significantly boosts your site’s security:
a). Strong Passwords
Create complex passwords that combine uppercase and lowercase letters, numbers, and special characters. Avoid using easily guessable passwords and consider using a reputable password manager to generate and store these passwords securely.
b). Two-factor authentication (2FA)
Enable 2FA to add a layer of security. This process requires users to provide two forms of verification—typically a password and a code sent to their mobile device or generated by an authentication app—making unauthorized access much more difficult.
#3. Install a Security Plugin
Improve your website’s protection by using a dedicated security plugin. Here are some top choices:
a). Wordfence
This plugin offers comprehensive security features, including a web application firewall, malware scanning, and login protection. It also provides real-time threat defense and alerts for potential security issues.
b). Sucuri Security
Sucuri provides a robust suite of tools for website security, including site monitoring, malware removal, and a website firewall. It helps in identifying and mitigating security threats effectively.
c). Solid Security
The Solid Security plugin is a WordPress security tool designed to protect websites from various threats. It shields your site from cyberattacks and prevents security vulnerabilities. It automatically locks out bad users identified by our Brute Force Protection Network which is nearly 1 million sites strong and makes use of your blacklist. In addition, it secures and protects the most commonly attacked part of your WordPress website – user login authentication.
#4. Remove Unnecessary Themes and Plugins
Unused themes and plugins pose a potential security threat, especially if they are outdated or contain vulnerabilities. Regularly audit your website for any inactive themes or plugins and promptly remove those that are not in use to reduce security risks.
#5. Set Correct File Permissions
File permissions dictate who can read, write, and execute files on your server. Properly configured permissions help protect your files from unauthorized access. Here’s a guide on how to set appropriate file permissions for a secure website:
1. Understand File Permissions Basics
Permissions control who can read, write, or execute files and directories. They are typically represented as three-digit numbers (e.g., 755 or 644).
2. File Permissions
▪️Files
Generally, files should be set to 644. This means the owner can read and write the file, while the group and others can only read it.
▪️Directories
Directories should typically be set to 755. This allows the owner to read, write, and execute (i.e., access files and subdirectories), while the group and others can read and execute.
3. Sensitive Files
Ensure sensitive files like wp-config.php in WordPress are set to 600 or 640. This restricts access so only the file owner can read or write to it.
4. Scripts and Executables
If you have scripts or executable files, such as CGI scripts, set their permissions to 700 or 755, depending on whether they need to be executable by others.
5. Recursive Permissions
When applying permissions to directories, use recursive settings cautiously. For instance, use chmod -R 755 directory_name to set permissions for all files and subdirectories, but be wary of applying write permissions (-R 777) as this can expose your site to vulnerabilities.
6. Ownership
Ensure that files and directories are owned by the correct user and group. For example, web server files might need to be owned by `www-data` or a similar user account used by your web server.
7. Regular Audits
Regularly review and audit file permissions to ensure they adhere to best practices and adjust as necessary to respond to security threats.
#6. Implement a Web Application Firewall (WAF)
A Web Application Firewall (WAF) serves as a critical layer of protection by filtering and monitoring HTTP traffic between your web application and the broader internet. It helps shield your site from a range of potential threats, including SQL injection, cross-site scripting (XSS), and other common attack vectors. Integrating a WAF can significantly improve your website’s security posture. Services like Cloudflare and Sucuri provide strong WAF solutions that integrate easily with WordPress, offering both ease of setup and ongoing protection.
#7. Conduct Daily Malware Scans
Website security is not foolproof, and timely detection of malicious activity is crucial. Malware scans thoroughly examine all files and databases for signs of unauthorized access or hidden threats.
Regular scans allow you to promptly identify and mitigate any security breaches, preventing further damage or exploitation by attackers. Automated scans like those provided by MalCare maintain constant vigilance over your website, ensuring its integrity.
#8. Secure Your wp-config.php File
The wp-config.php file is crucial as it contains sensitive configuration details for your WordPress site, including database credentials. To secure this file:
a). Move It
If possible, relocate the wp-config.php file to a directory above the root directory of your WordPress installation. This reduces the risk of it being accessed via the web.
b). Set Permissions
Configure file permissions to limit access. Ideally, set the file permissions to 400 or 440, which restricts write and execute permissions and minimizes the risk of unauthorized access.
#9. Limit Login Attempts
Excessive login attempts can be a sign of a brute force attack, where an attacker systematically tries various passwords to gain unauthorized access. To mitigate this risk, it is essential to limit the number of login attempts allowed before temporarily locking out the user. This helps prevent unauthorized access and secures your site against potential attacks. Many security plugins for WordPress offer built-in options to manage login attempts, but if your current setup lacks this feature, standalone plugins such as Login LockDown or Limit Login Attempts Reloaded can be effectively used to implement this security measure.
#10. Regular Backups
Regular backups are a vital part of maintaining your website’s security and integrity. They ensure that you can quickly restore your site in the event of an attack or data loss. Use reliable backup solutions like UpdraftPlus or BackupBuddy to create and manage backups. It is also crucial to store these backups in a secure, offsite location, such as cloud storage services, to safeguard against data loss due to server issues or physical damage.
#11. Disable Directory Listing
Directory listing can expose the contents of your directories to potential attackers, providing them with valuable information that can be exploited. To prevent this, disable directory listing by adding the directive Options -Indexes to your htaccess file. This simple configuration change will ensure that visitors cannot view a directory’s contents directly through their browser.
#12. Monitor Your Website
Active monitoring of your website is crucial for detecting unusual or suspicious activities.
Utilize tools such as Google Search Console and Wordfence to stay informed about potential issues or security breaches. These tools provide alerts and insights that help you address problems before they escalate.
#13. Secure Your Database
Given that your database is a prime target for attackers, implementing robust security measures is essential. Improve your database security by:
a). Changing the Default Table Prefix
Alter the default table prefix (e.g., wp_) to a unique value during the installation process to make it harder for attackers to exploit common vulnerabilities.
b). Using Strong Database Passwords
Create complex, strong passwords for your database to prevent unauthorized access.
c). Limiting Database User Permissions
Restrict the permissions of database users to only what is necessary for their functions, minimizing potential exposure in case of a breach.
Additional Tips to Note
▪️Be Cautious with Plugins
Only install plugins from trusted sources and remove unused ones.
▪️Limit User Permissions
Assign appropriate permissions to users to minimize potential damage.
▪️Educate Your Team
If you have multiple users, ensure they understand security best practices.
