Server Message Block or SMB is a protocol used for file sharing. It provides the Read and Write operations on network devices. This is widely used while a user is accessing a Linux-based Server. The latest version of this protocol is SMB2 which succeeds SMB 1. SMB 2 contains more fixes to vulnerabilities that SMB 1 was prone to. SMB 1 was vulnerable being a gateway to various modern ransomware and hence has been disabled by default by Microsoft starting with Windows 10 v1709.
You may see the following error when you try to share:
This share requires the obsolete SMB1 protocol, which cis unsafe and could expose your system to attack. Your system requires SMB2 or higher.
Your system requires SMB2 or higher
