AWS Blog lets us know that Amazon has finally implemented one of the most useful features ever – descriptions on Security Groups rules. Previously, one could provide a description to the Security Group only, for example: “Proxy Server Access”. Which wasn’t very useful, as it was almost obvious. But now one can add a description to every rule inside the Security Group. So when you have a Security Group with a bunch of IP address ranges, you can now describe each one of them. For example: “HQ Office”, “UK Office”, “Boss At Home”, etc.
