WN10-SO-000100 - The Windows SMB client must be configured to always perform SMB packet signing.

Information

The server message block (SMB) protocol provides the basis for many network operations. Digitally signed SMB packets aid in preventing man-in-the-middle attacks. If this policy is enabled, the SMB client will only communicate with an SMB server that performs SMB packet signing.

Solution

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> Security Options >> 'Microsoft network client: Digitally sign communications (always)' to 'Enabled'.
