iThemes Security pro gpl (formerly known as solid Security) is a powerful and comprehensive WordPress security plugin designed to protect your website from common security threats and vulnerabilities. It focuses on providing essential security features to harden your WordPress installation, detect vulnerabilities, and secure your site from potential attacks.

Key Features of iThemes Security pro gpl :

1. Brute Force Protection:

• Login Protection: iThemes Security helps prevent brute force attacks by limiting the number of login attempts from a single IP address. If an IP address exceeds the set number of attempts, it is automatically locked out.
• Strong Password Enforcement: You can enforce strong passwords for all users, which is critical for preventing password-based attacks.
• Password Expiration: The plugin can force users to change their passwords periodically, adding an extra layer of security to prevent password compromise.

2. Two-Factor Authentication (2FA):

• iThemes Security includes two-factor authentication (2FA) as a built-in feature, providing an extra level of login security by requiring both a password and a second factor (such as a code sent to a mobile device or email).

3. File Change Detection:

• The plugin monitors your WordPress installation for any file changes. If any files are modified, added, or deleted, you will be notified. This helps detect unauthorized changes that may indicate a hack or malware infection.

4. Database Backups:

• iThemes Security includes the option to schedule automatic database backups. In the event of a security breach, having a backup of your database ensures that you can quickly restore your site to a secure state.
• Backup Notifications: You can set up notifications to receive an email whenever a backup is completed.

5. Security Logging:

• iThemes Security provides detailed security logs, which record important security events such as login attempts, user activity, and file changes. This can help you track suspicious activity and investigate security incidents.

6. Malware Scanning:

• The plugin integrates with Sucuri’s SiteCheck malware scanner to automatically scan your website for known malware and security vulnerabilities. You can schedule scans or run them manually as needed.

7. 404 Detection:

• iThemes Security can detect and block IP addresses that generate too many 404 errors, which often indicates that someone is scanning your site for vulnerabilities or attempting to find weak points.

8. Hide WordPress Login URL:

• You can change the default WordPress login URL (typically yoursite.com/wp-login.php) to something unique. This adds a layer of security by obscuring the login page from bots and attackers.

9. Admin User Protection:

• iThemes Security helps you disable the default “admin” username, which is a common target for attackers, and rename it to something more secure.

10. File Permissions Check:

• The plugin checks your file permissions to ensure they are properly configured for security. This prevents unauthorized access to sensitive files and directories.

11. Lockout Feature:

• Temporary Lockout: You can set the plugin to lock out users or IP addresses after multiple failed login attempts, 404 errors, or other suspicious activity. This prevents attackers from making further attempts to compromise your site.
• Permanent Bans: iThemes Security also allows you to ban specific IP addresses permanently if they are repeat offenders.

12. Security Dashboard:

• The plugin provides a security dashboard that consolidates all security notifications, logs, and alerts into a single, easy-to-navigate interface. This makes it simple to monitor your site’s security status.

13. Google reCAPTCHA Integration:

• You can integrate Google reCAPTCHA to add an extra layer of login security. This prevents automated bots from attempting to log in to your site by requiring human verification.

14. WordPress Tweaks:

• iThemes Security offers a range of WordPress tweaks to improve security, including disabling XML-RPC (a common attack vector), hiding the WordPress version, and restricting access to sensitive areas of the site (like the WordPress dashboard).

15. Scheduled Security Scans:

• The plugin allows you to schedule regular security scans to automatically check for vulnerabilities and suspicious activity.

16. User Action Logging:

• iThemes Security tracks and logs all user actions, such as logins, failed login attempts, and changes to content. This helps you track suspicious activity and hold users accountable for their actions.

17. Security Check Pro (Premium Feature):

• The premium version includes Security Check Pro, a feature that performs a comprehensive security scan of your website and recommends specific actions to improve your site’s security.
