Website Security Basics for Beginners

Basic website security protects your business, customers and reputation. Most attacks target simple weaknesses that are easy to fix.

The essentials

• HTTPS on every page.
• Strong unique passwords and multi-factor authentication for admin accounts.
• Timely updates to software, themes and plugins.
• Least-privilege access: give people only the access they need.
• Secure backups stored separately.
• Monitoring for unusual activity.

Protect secrets

Store API keys and database credentials on the server, never in public front-end code or public code repositories.

Validate input

Validate user input and apply access controls to admin and seller functions, so users cannot reach pages or data they should not.

Test your backups

Test backup restoration, not just backup creation. A backup you cannot restore is not a backup.

Ongoing process

Security is an ongoing process. High-risk payment and personal-data systems may need professional review and compliance work.

Frequently asked questions

Is HTTPS enough to make a site secure?

No. HTTPS protects data in transit, but you also need updates, strong passwords, access control and backups.

How often should I back up my website?

As often as your content changes — daily for stores and active sites.
