Hardening AWS EC2 AMI image

Hardening AWS EC2 AMI image
Hey all,

Currently have a working private instance, I am looking to harden the Amazon AMI image.

What are the recommended steps to harden the server and agent in AWS?

I have looked around, but did not see any obvious list of steps. So here are my current attempts:

1. I have edited the security group to block ssh inbound traffic except from some trusted ips.

2. I have restricted the http inbound traffic, but when the agent restarts, I am not sure how to add that new ip to the inbound rule (or if I can assign a known ip to the restarted agent).

3. I have added basic auth to the server, but when the agent connects it gets blocked, so I need to dig into how to send the auth from the agent.

4. Will be adding a self signed cert to the server, but I suspect I will need to edit the agent to add the trusted cert / allow invalid certs.

5. Haven't explored if there is away to use security groups in a more effective manner.

Thanks for any suggestions!
