Acronym for Server Message Block. A file-sharing protocol designed to allow networked computers to transparently access files that reside on remote systems over a variety of networks. The SMB protocol defines a series of commands that pass information between computers. SMB uses four message types: session control, file, printer, and message. See also LAN Manager, NetBIOS, Samba.

Množina: SMB signings

A secure version of Server Message Block (SMB) protocol.
SMB signing helps protect network hosts against exploits targeting NetBIOS and other SMB-based services.
Traditional SMB authentication is vulnerable to man-in-the-middle (MITM) attacks, but by implementing
mutual authentication SMB signing thwarts this kind of attack. SMB signing strengthens SMB authentication
by adding digital signatures into SMB packets so that both the client and the server can verify the authenticity
of the packets. SMB signing is supported by Windows NT 4.0 Service Pack 3 and later, but the feature is not enabled by default. While SMB signing pre-vents exploits such as the SMBRelay Trojan from being effective, it does so at an added performance cost because of the increased processing and network traffic required to digitally sign each SMB packet.
