In this tutorial we are going to show how easy it is to build a notification feed using GetStream.io. First of all, let's quickly introduce you to our fictional example app. It's called bug-your-friends.com and allows you interact with your friends, ping them, follow them or poke them. Here's a quick list of example interactions:
- poke another user (eg. Thierry pokes Alessandra)
- follow a user (eg. Tommaso follows Iris)
- ping a user (eg. Josie pings Carolina)
Whenever a user is part of one of these interactions, we want to update his notification feed, update the number of unseen and unread
I often get asked which tools are good to use for securing your AWS infrastructure so I figured I'd write a short listof some useful Security Tools for the AWS Cloud Infrastructure.
This list is not intended be something completely exhaustive, more so provide a good launching pad for someone as they dig into AWS and want to make it secure from the start.

Everything I'm talking about below is not new, but I thought it was an interesting idea and realized I already had the majority of pieces in place to play with it. I want to share what I learned. If you are at all interested in exploring this topic further a good paper on it is here. Also, a few years ago IOActive published a blog post on the technique which is also a good read. Finally, the last two paragraphs in section 6 of RFC5246 clearly document the problem the best I've been able to find:
Any protocol designed for use over TLS must be carefully designed to
deal with all possible attacks against it. As a practical matter,
this means that the protocol designer must be aware of what security
properties TLS does and does not provide and cannot safely rely on
the latter.
