Category: PROTOCOLS      

Application: SMB Protocol      

Server Message Block (SMB) operates as an application-level network protocol mainly used to provide shared access to files, printers, serial ports, and miscellaneous communications between nodes on a network. It also provides an authenticated Inter-process communication (IPC) mechanism. Most usage of SMB involves computers running Microsoft Windows, where it is often known as "Microsoft Windows Network".

This SonicWALL signature identifies legitimate SMB traffic.
