Encrypt confidential, sensitive, or high-risk information

To better protect the sensitive data that the University of Delaware collects, all computer files that contain confidential, sensitive, or high-risk information must be encrypted.

Encryption is the process of securing data so that it can only be used by those who should have access to it. If a computer is stolen or used by someone without permission, encrypted files and folders will be inaccessible.


IT using AES Crypt to encrypt unprotected SSNs
UD IT routinely scans University servers to identify unencrypted files containing Social Security Numbers (SSNs). Any unencrypted file containing SSNs found on the servers will be encrypted with AES Crypt. If you see a file with the ".aes" file extension, it has been encrypted. To receive the password to decrypt the file, contact the IT Support Center.
