Using websites to pass data around the Internet is a staple of technology as we know it today. Installing even the most simple new tool or system will likely require you to download software or an update, or to register your information with a website. As an IT professional, I hope that you are familiar with HTTP versus HTTPS websites and the importance of distinguishing between the two. But now that we have a website running, how can we enable HTTPS on it so that we can protect this data that is traversing back and forth between our web server and the client computers?

It is typically the web developer's job to tell a website when to call for HTTPS, so you shouldn't have to worry too much about the actual content of the website. As the server administrator, however, you need to make sure that once HTTPS is called for on the website, your web server is capable of processing that traffic appropriately.
