To allow SSH access to an instance, an inbound rule should permit access for TCP port 22. It’s best to restrict this rule to your own IP address, or those in your network.

If a process running on an instance will need to access a MySQL server elsewhere, an outbound rule over TCP port 3306 will allow it. The destination could be the IP address of the MySQL server or, if the server is running in EC2, the server’s security group.
