Is my CMU Box account secure?
Yes. CMU Box accounts use an encrypted connection for all uploads and downloads. Once your files are uploaded, they're encrypted in storage.
How does Box protect my data?
Box protects data using both access controls and encryption. Access to your CMU Box account is controlled using your Andrew userID and password. When you access cmu.box.com, you will first be redirected to login.cmu.edu to authenticate. Access to the files you store in Box is controlled by the permissions you set. By default, access is private to the account holder. All communication with Box from your computer or mobile device is encrypted using SSL and data is encrypted in storage using 256-bit AES encryption. Other security features include file-level password protection and access notification. Additional information can be found by reading Box’s security whitepaper.
Can I use my CMU Box account to store institutional data?
For faculty and staff members, restricted data (data deemed sensitive by the institution) may not be appropriate for use with your CMU Box account. You should consult with the appropriate data steward in your department prior to uploading such files.
For students, most of your documents can be safely stored in your CMU Box account. Use caution when storing documents that contain sensitive information such as your Social Security number or credit card information.
Does Box back up my data?
Box takes steps to back up your data to protect against system failures. However, it is important to note that changes made by a user can have a lasting effect. If a file is overwritten or becomes corrupt, it may not be recoverable. Each CMU Box account has a Trash folder where deleted files can be recovered. However, once the Trash is emptied, files may not be recoverable. Files do stay on the Box servers for short period of time after the Trash is emptied; however, a ticket will need to be opened with Box to determine whether a file or folder is actually recoverable. Box also maintains a document’s version history. If used correctly, a user can recall previous versions of a document. This could allow a user to recover from inadvertent changes.
