AWS LightSail now has the ability to restrict IP addresses in their firewall rules. LightSail instances can now be secured by limiting firewall rules from an IP CIDR block or a single IP address. For example, you can restrict who can SSH into your instance by limiting it to just your IP address, so only you can SSH into your machine. Another feature AWS added in their LightSail firewall is support for ping, which could be helpful for monitoring and checks.

When off the grid, I enjoy riding my electric skateboard. I've surfed, snowboarded and played saxophone in the past. I hope you find this site helpful. It's powered by WordPress and hosted in AWS.
