Question 1

Why should a systems administrator disable unused services and filtering ports?

Accepted Answer

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.

Question 2

What is Samba used for?

Accepted Answer

Samba is an open-source implementation of CIFS; with Samba,*nix servers can share resources with Windows clients,and Windows clients can access a *nix resource without realizing that the resource is on a *nix computer.Samba has been ported to non-*nix systems,too,including OpenVMS,NetWare,and AmigaOS.Samba is very useful because many companies have a mixed environment of Windows and *nix systems.

Question 3

What is the Common Internet File System (CIFS)protocol?

Accepted Answer

Common Internet File System (CIFS)is a standardized protocol that replaced SMB in Windows 2000 Server and later,but to allow backward compatibility,the original SMB is still used.CIFS is a remote file system protocol that enables computers to share network resources over the Internet.In other words,files,folders,printers,and other resources can be made available to users throughout a network.For sharing to occur,there must be an infrastructure that allows placing these resources on the network and a method to control access to resources.
