​Did you know you can use LANGuardian to identify all obsolete SMB1 traffic?

Recently, one of our customers contacted us with a use case, where they had heard Microsoft recommends to stop using SMB1. They simply wanted to see if SMB1 was being used on their network and if LANGuardian could detect such traffic.

In response to this request, our Development Team have implemented the SMB protocol version reporting in LANGuardian 14.1.3. See here for our latest release notes.

SMB1 protocol is not secure and is inefficient. Some additional reading can be found here on this Microsoft blog post.

Using the Top File Share Servers report, you can see at a glance SMB1 servers. From here, you can quickly identify all obsolete SMB1 traffic. 

The steps to create the report as follows:
1. Click on All Reports in the LANGuardian menu bar
2. In the Windows File Shares section, click on More >>
3. In the Advanced section, click on Top File Share Servers
4. From the Version field, select SMB1
4. Click Run Report
5. When LANGuardian displays the report, click Actions on the report menu bar and select Save Report
6. Enter a name and description for the report, then click Save. The new report will now be listed in the My Reports section

Note, you will need to update your software in order to avail of this new feature.
Use the following upgrade link https://x.x.x.x/sysadm/update.cgi
