SMB Signing | ND

SMB Signing is a hashing implementation used to keep your data integrity and network structure secure. A Server Message Block protocol is used as a basis for file transfers, pushing group policy settings and even executing remote commands through something like PSexec.

Therefore, it is important to verify the origin and integrity of the data being sent. By signing all the packets sent over, a hash can be calculated by the recipient and compared to the signature to verify the contents. SMB signing is enabled by default on Domain Controllers, but is not enabled by default on most all other devices. If your network and computers can support SMB signing, it is highly recommended to upgrade security. For more information about SMB signing and how to enable it, visit the link here.
