SMB Protocol

The Server Message Block (SMB) Protocol, also known as CIFS, is a file and printer sharing protocol which serves as the basis for Microsoft's Distributed File System implementation.

Due to the constantly rising of network security importance, the SMB security mechanism has evolved over the years and now offers the following safety measures:

  • User Authentication
    • Kerberos
    • Domain Authentication
  • Message Signing
  • Message Encryption

The usage of the SMB protocol on the network increases from year to year. In contrary to FTP and HTTP, the SMB protocol allows not only copying an entire file, but grants access to files over the network. File editing, for example, can be executed over SMB, without changing its location.

NFS is also a file sharing protocol similar to SMB. However, NFS is only native to the Linux world whilst using it on a Windows computer requires installing a patch. SMB is a native solution for Windows, Linux and Macintosh.
