How do you change the name and description of a security group in AWS EC2?
My security group is named
quick-start-1 (the default) and I want to change it to "
HTTP, HTTPS and Limited SSH".

It's not possible to rename a security group, by GUI or by API.
You can dynamically assign security groups assigned to VPC EC2 instances. Create a new SG with the desired name and the same rules.
It's not possible to change the security group that is assigned to EC2 classic instances.
If you must change the security group for an EC2 classic instance, then you need to:
You cannot rename a security group but you can copy it into a new one.
On the AWS console go to EC2 -> Security Groups -> Select the SG -> Click actions -> Copy to new.
Give it a name and description that suits your taste.
After that you can associate this security group with your instances (making it redundant with the old one).
Finally, dissociate the old security group from your instances (rules remains the same since the new SG is a copy) and delete the SG.
It is a little bit of work, but it does get the job done with no downtime.
You're not the first to want this, and you're not the first to be disappointed.
Also, you cant change security group memberships for an instance once launched. :-(
I'm 99% sure this cant be done via the web GUI. Maybe via API shenanigans, but if so i've never seen it. I've wanted it myself often enough.
