Analysis of information sources in references of the Wikipedia article "Server Message Block" in English language version.
This article addresses [...] Server Message Block (SMB) message signing.
This security mechanism in the SMB protocol helps avoid issues like tampering of packets and "man in the middle" attacks. [...] SMB signing is available in all currently supported versions of Windows, but it's only enabled by default on Domain Controllers. This is recommended for Domain Controllers because SMB is the protocol used by clients to download Group Policy information. SMB signing provides a way to ensure that the client is receiving genuine Group Policy.
By default, SMB signing is required for incoming SMB sessions on Windows Server 2003-based domain controllers.
