Best Practices

Drupal is the same as any other web site: there's best practices that are necessary to implement. Check out this list of best practices for Drupal, divided between General and Security:

General

1. Keep all components up to date (Drupal core, themes, modules, etc.)
2. Make sure user permissions are set correctly to prevent unauthorized access.
3. Make regular backups of your site to prevent loss of data.
4. Plan out how you want your site to look before creating it.
5. Include metadata (such as descriptions and keywords) to enhance SEO on your site.

Security

1. Consider applying security modules to prevent spam or hacks, such as CAPTCHA or 2FA.
2. Stick with modules that have Drupal's seal of approval in order to prevent vulnerabilities within your platform.
