All content is stored as encrypted data in the database, and then regenerated when the course is published or downloaded. This not only improves the performance of our authoring tool but also significantly increases security, since the only way to access the content is through the password-protected account. The database is not connected directly to the internet nor accessible by any other Udutu User, other than our System Administrator. Only authorized users can access their assigned accounts.
