Vulnerability "SMB Signing Disabled or SMB Signing Not Required

Joe Brown1709161698


Hi Experts,


Our security team has identified a vulnerability "SMB Signing Disabled or SMB Signing Not Required" and they have suggested to Enable the SMB Signing.

As per our security team,

"Without SMB signing, a device could intercept SMB network packets from an originating computer, alter their contents, and broadcast them to the destination computer. Since, digitally signing the packets enables".


So we wanted to confirm if anybody has enabled it. If yes , then is there any issue we faced and how we mitigated it? We dont have test infra so we have to do it in Prod directly.


We are using XenApp 6.5 with HRP07 on Windows server 2008 R2. We have Published Server desktop as well applications published in our infra. we also use web based applications in our citrix farm.
