SMB (Server Message Block)

Definition

Server Message Block (SMB), also called Common Internet File System (CIFS) in an original version, is a network protocol for file, print and other server services in computer networks. It is a central part of the network services of the Windows product family and allows access to files and directories located on another computer. It is also used by the freely available software project Samba to enable Windows systems to access resources of Unix-based systems and vice versa. Thus it is also used on many NAS systems.

SMB implements a network file system similar to NFS and is thus largely independent of the underlying file system of the server.

When installing Windows 10 und Windows 11 SMB 1.0  is not activated, as it is a potential risk factor.
