What is the CUI Environment?

The CUI Environment is a NIST 800-171 compliant vault used by researchers for handling and analyzing Controlled Unclassified Information. It is hosted in one of the Division of Information Technology's (DIT) data centers. The system provides investigators a place to upload and store files, and access virtual machines for performing analysis. It uses a dynamic encryption process that prevents access to data by anyone but those designated by a principal investigator (PI) or file owner.

To access the CUI Environment, you must connect to the University of Maryland's (UMD) Virtual Private Network (VPN) and use the tiCrypt Connect application.


How do I get access to tiCrypt?

You will only be granted access to download tiCrypt after your project PI has submitted a request to add you to the appropriate group to the Research Technology team. Furthermore, your account registration will only be approved after you have completed the prerequisite training in ELMS-Canvas and the Research Technology team has completed your identity check.

Supported web browsers for tiCrypt are Chrome and Firefox.
