What is WebDAV over SSL? (Okay to use for confidential data)

WebDav (Web-based Distributed Authoring and Versioning) is a file transfer protocol that is used at Cornell in conjunction with CUWebAuth and Kerberos to provide additional security for single-sign on connections.

The WebDAV client sends an encrypted NetID and password to the kProxy server. The kProxy server logs into Kerberos and obtains credentials which are sent to the WebDav server. This protects NetID and password information while still allowing the ease of use provided by single sign-on.

For more information, see File Transfer Using WebDAV over SSL.

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.
