Why should a systems administrator disable unused services and filtering ports?
What will be an ideal response?
Disabling unneeded services and deleting unnecessary applications or scripts make sense because they give intruders a potential point of entry into a network. If you have a Windows Server 2016 system acting as a file server, you certainly don't need DNS services running on it; doing so leaves port 53 TCP/UDP open and vulnerable to attack. Open only what needs to be open, and close everything else.
