Answer 1

Here's a way to restrict AWS security group to your dynamic IP address for SSH.

You can write a cronjob to regularly repeat the steps below:

1. Fetch external IP address (e.g. http://checkip.amazonaws.com/)
2. Fetch security group details using AWS SDK
3. Loop through all security rules, check for port 22
4. If IP address mismatches that from step 1, update it.
