Make Drupal Secured
To make drupal more secured:
1. Limit access only to registered users.
2. Disable registration and manually register the users who are allowed to access the information.
3. Disable permission for anonymous users this will make the drupal more secured.
4. Use private file system, so unauthenticated users cant view the attachements / images posted.
5. Add robots.txt with the following lines:
User-agent:*
Disallow:/
6. Final important thing is to implement Drupal on a dedicated server and restrict access to HTTPS. Dedicated server is more secured.
