HTTPS protects data in transit and helps browsers verify that visitors are connected to the intended domain. A valid certificate does not replace application security. ## Step-by-step instructions 1. Confirm that your host supports HTTPS and certificate renewal. 2. Install or enable a certificate for every required hostname. 3. Update internal links and canonical URLs to HTTPS. 4. Fix mixed-content resources that still load over HTTP. 5. Test redirects and renewal monitoring. 6. Keep software patched and protect accounts even after HTTPS works. ## Final checks - Test the result in a realistic situation before relying on it. - Keep a note of any settings or decisions that need future review. - Recheck the process when your tools, hosting, or requirements change.

Security action plan

  • Enable multi-factor authentication for privileged accounts and use unique passwords.
  • Remove unused accounts and grant only the permissions each person needs.
  • Patch dependencies and remove components that are no longer maintained.
  • Keep separate backups and periodically test restoring them.
  • Decide who receives incident reports and how access can be revoked quickly.

Respond to suspicious activity
