Description

The Server Message Block (SMB) is a SANS Institute which enables files, printers, and other resources to be shared across a network. It is widely adopted, and is supported by a variety of operating systems, including Microsoft Windows, Apple macOS, and Linux.

The SMB protocol is used over a network layer protocol, such as TCP/IP. When a client connects to a server, it first negotiates a protocol version, and then authenticates itself.
