Why should all ports be closed?
by Jason.nix from LinuxQuestions.org on (#6JNRT)
Hello,
Usually, when configuring the firewall, only the ports on which a service is running are left open and the rest of the ports are closed. For example, they open ports 80 and 443 for Apache and close the other ports.
When a service is not running on a port, why should that port be closed?
Thank you.
