What is Microsoft File Sharing (SMB/CIFS)?

Warning: Do not use this option for confidential data.

Microsoft File Sharing (using the underlying SMB/CIFS protocol) is a software application that allows Windows or Macintosh and Unix computers to interact with each other. It creates a connection from the Win/Mac client to the server, allowing you to see directories on the server as if they were on the client computer.

Microsoft File Sharing (SMB/CIFS) is not encrypted over the network. For the transfer of confidential data, Microsoft File Sharing (SMB/CIFS) is not allowed. Policy 5.10, Information Security, classifies as confidential any of the following data elements when they appear in conjunction with an individual’s name or other identifier:

  • Social Security number
  • Credit card number
  • Driver’s license number
  • Bank account number
  • Protected health information, as defined by HIPAA

If you are unsure which protocol to use instead, send e-mail to The Systems Support group will work with you to find a secure solution.
