I'm working on my very first drupal website and it will consist of a login form which will then give the user access to a form. This next form will allow the user to query my database to show the closest matches in the category they search - and when they select one they will able to fill in some details on another form, attach some files and then send the information via email.
Security is the most important factor here as the information is all confidential. Can you help me work out what plugins/modules I should be looking at to make my system most secure. And what possible security problems I need to be aware of?
[Note: I have used cmsmatrix.org to compare what the CMS can do and one thing I've noticed is for Drupal it says it can't do things like ssl logins or ssl pages. So should I even be using Drupal in that case?]
