Major Checklist for WordPress Website Development

Here's a major security checklist for WordPress website development:

1. Keep WordPress Core, Themes, and Plugins Updated

Regularly update WordPress core, themes, and plugins to the latest versions to patch security vulnerabilities and ensure compatibility with the latest security standards.

2. Use Secure Hosting

Choose a reputable hosting provider that offers robust security features, including SSL/TLS encryption, firewalls, malware scanning, and regular backups.

3. Strong User Authentication

Enforce strong password policies for user accounts, encourage the use of two-factor authentication (2FA), and limit login attempts to prevent brute-force attacks.

4. Limit Access Permissions

Restrict access permissions for users and roles to minimize the risk of unauthorized access to sensitive areas of the WordPress dashboard and files.

5. Secure File Permissions

Set appropriate file permissions on WordPress files and directories to prevent unauthorized access or modification by malicious users.

6. Implement HTTPS

Secure your website with HTTPS encryption to protect user data during transit and enhance trustworthiness and SEO rankings.

7. Use Security Plugins

Install reputable security plugins such as Wordfence, Sucuri Security, or iThemes Security to monitor and protect against malware, brute force attacks, and other security threats.

8. Enable Web Application Firewall (WAF)

Deploy a WAF to filter and monitor incoming web traffic, intercept malicious requests, and block suspicious IP addresses or patterns.

9. Disable Directory Listing

Prevent directory listing by disabling directory browsing to prevent unauthorized access to sensitive files and directories on the server.

10. Regular Backups

Implement automated backups of your WordPress website, including both files and databases, and store backups securely offsite to facilitate quick recovery in case of data loss or security incidents.

11. Security Headers

Configure HTTP security headers such as Content Security Policy (CSP), X-Frame-Options, X-XSS-Protection, and X-Content-Type-Options to mitigate common web vulnerabilities and protect against cross-site scripting (XSS), clickjacking, and MIME-sniffing attacks.

12. Database Security

Harden database security by using unique database prefixes, restricting database access, and regularly auditing and optimizing database tables to minimize the risk of SQL injection and data breaches.

By adhering to this comprehensive security checklist, WordPress developers can strengthen the security posture of their websites, mitigate common vulnerabilities and threats, and ensure a safe and trustworthy online experience for users. Remember that security is an ongoing process, and regular monitoring, updates, and proactive measures are essential to staying ahead of evolving threats.
