SSL requires a certificate from a CA (certificate authority) like cacert.org or godaddy.com and isn't directly a Drupal-related task. It's a web server-related task. If you have a webhost you can ask their tech support to help you get a certificate (they can create one for you for free, though using a self-signed certificate can possibly confuse non-technical users when their browsers display a confirmation dialog before accessing the site).
Once you have a certificate, you can use a third-party module like Secure Pages to redirect certain pages (if not all of them) to the secure https version of a Drupal site.
Security is a huge topic to discuss, so I'll leave off by recommending the Login Security module. It can prevent unauthorized login attempts in highly configurable ways.
ps. Please don't post the same question multiple times.
