Security, backups and speed
Keep WordPress sites safe and fast.
📖 Key ideas
- Update WordPress core, themes and plugins regularly.
- Use strong passwords and two-factor authentication.
- Install a security plugin and limit login attempts.
- Schedule automatic backups stored off-server.
- Speed up with caching, image compression and a CDN.
💡 Real-life example: Maintenance is servicing a car: regular oil changes (updates) prevent breakdowns (hacks).
