EC2 Instances Several Ports Open

Hello there,

It is not considered a good practice to have the ports of your resources open to the public as attackers may gain access to your resource and cause harm.

The best approach to fix this would be to configure your security group to control the traffic to your resource. A security group acts as a virtual firewall for your instance to control inbound and outbound traffic, for more information on security groups, please see reference [1].

You can configure the security group of your EC2 instance by allowing traffic from your own ip address or a selected range of ip addresses instead of having your ports open to the public.

For specific security group rules, please see reference [2].

I hope this helps.
