This article describes Server Message Block (SMB) signing. SMB signing is a security mechanism in the SMB protocol and is also known as security signatures. SMB signing is designed to help improve the security of the SMB protocol. SMB signing was first available in Microsoft Windows NT 4.0 Service Pack 3 (SP3) and Microsoft Windows 98.

When it was first introduced to the public, the remote file protocol was called SMB (Server Message Block). SMB was used, for instance, by Microsoft LAN Manager in 1987 and by Windows for Workgroups in 1992. Later, a draft specification was submitted to the IETF under the name Common Internet File System (CIFS).

Microsoft SMB Protocol Authentication. The security model used in Microsoft SMB Protocol is identical to the one used by other variants of SMB, and consists of two levels of security—user and share. A share is a file, directory, or printer that can be accessed by Microsoft SMB Protocol clients. User-level authentication indicates that the client attempting to access a share on a server must provide a user name and password.

Server Message Block. In computer networking, Server Message Block (SMB), one version of which was also known as Common Internet File System (CIFS, /ˈsɪfs/), operates as an application-layer network protocol mainly used for providing shared access to files, printers, and serial ports and miscellaneous communications between nodes on a network.

ARCHIVED: What is Server Message Block (SMB)? Server Message Block (SMB) is the Internet standard protocol Windows uses to share files, printers, and serial ports. In a networked environment, servers make file systems and resources available to clients. Clients make SMB requests for resources, and servers make SMB responses in what's described as a client server, request-response protocol.

SMB (Server Message Block) is a remote file protocol commonly used by Microsoft Windows clients and servers that dates back to 1980’s. Back when it was first used, LANs speeds were typically 10Mbps or less, WAN use was very limited and there were no Wireless LANs.

SMB is also known as the Common Internet File System (CIFS). SMB was engineered to run via the following application programming interfaces (API) for the network basic input/output system (NetBIOS) and the NetBIOS extended user interface (NetBEUI):

Server Message Block Protocol (SMB protocol) The Server Message Block Protocol (SMB protocol) provides a method for client applications in a computer to read and write to files on and to request services from server programs in a computer network.

Most usage of SMB involves computers running Microsoft Windows, where it was known as Microsoft Windows Network before the subsequent introduction of Active Directory. Corresponding Windows services are LAN Manager Server (for the server component) and LAN Manager Workstation (for the client component).

Using the SMB protocol, an application (or the user of an application) can access files at a remote server as well as other resources, including printers, mailslots, and named pipes. Thus, a client application can read, create, and update files on the remote server.
