Whether you’re deploying proprietary or open source test creation software, you should always secure your environment through both organizational and IT administrative means to prevent unauthorized access to test content, student grades, etc.
Additionally, you should implement anti-cheating measures during test delivery. There is no distinction here between proprietary or open source software.
To keep your assessments secure, TAO encrypts data via HTTPS, and provides User Identification via encrypted passwords. It also supports back-office identification based on assigned roles and access rights.
