Require Client SMB Packet Signing, if using mount.cifs Require packet signing of clients who mount Samb Ashares using the 'mount.cifs' program (e.g., those who specify shares in '/etc/fstab'). To do so, ensure signing options (either 'sec=krb5i' or 'sec=ntlmv2i') are used. See the 'mount.cifs(8)' man page for more information. A Samb Aclient should only communicate with servers who can support SMB packet signing. Packet signing can prevent man-in-the-middle attacks which modify SMB packets in transit.
