This blog entry will be short as it was much easier than I thought. To secure an Amazon API, you can use an IAM user, an an API key or a mixture of both. Since I am slowly working my way up from basic to more advanced, I choose to secure the satellite call with an API Key. I played around with it a little until I found this article (see reference #4) which filled in the last bits of missing information.
The next blog entry will be using an IAM user. I will probably mix the IAM user with an API key…you can never be to secure 🙂
