Only enable the ports, protocols, and services that are strictly necessary for your system to function.

Use the netstat command on your system and/or scan your IP address with nmap from another machine to
understand what ports are open. Limit unnecessary network exposure by disabling services or using a firewall.

Configure an appropriate resource limit or cost cap on your cloud services. Attackers can make excessive requests to your cloud services, exhausting your resources or incurring a large bill. Implementing a resource limit or cost cap can mitigate this risk.
