Three layers of security protect WordPress: SSL encryption, authentication strength, and database protection. This guide implements all three.
1. Installing and Configuring SSL
SSL encrypts data between users and servers. Install Let’s Encrypt certificates (free) or commercial certificates. Configure your site to force HTTPS on all pages.
After SSL installation: update WordPress address and site URL to https://, set HSTS headers, and verify mixed content. Google prioritizes HTTPS sites in search rankings.
2. Setting Up 2FA
Two-factor authentication requires a second verification factor (phone, authenticator app, email). Use Wordfence, iThemes Security, or Google Authenticator plugin.
Implementation Strategy
Enforce 2FA for admin accounts immediately. Make 2FA optional for editors. This protects critical accounts with minimal user friction.
3. Database Backup Methods
Regular database backups protect against data loss. Use automated solutions like BackWPup. Backup at least daily. Test restoration to ensure backups work.
4. Access Control Lists
Change database prefix from wp_ to something custom. Use strong database passwords. Limit database access to application servers only. Remove root access where possible.
Security is trust. LocalPro handles infrastructure security so you focus on business. Protect client data with enterprise-grade security and compliance.
