This morning there was a flurry of effort to locate an article called “Hacking WebCT.” My coworker was able to locate it.Â We were disappointed.Â
The main points of the article were:
- Lazy administrators make compromising user accounts easy.
- Lazy instructors make getting questions for assessments easy.
These apply to any LMS. So, here is some advice to counter the issues raised in this article.
Default passwords are the bane of any system.Â Make users change them. (Yes, this increases support tickets.) This usually comes about because the administrators did not integrate the LMS authentication with LDAP, Kerberos, or CAS Â which allows for central management of accounts.Â Central management of accounts means fewer accounts are likely to sit around with easily guessed intially imposed credentials.Â
Linking many services together also raises the exposure should one account account me compromised. Enforce decently strong passwords. Too strong and frequently changed password will encourage users to employ means of remembering passwords which defeat the point. Passwords probably should not ever be just birthdays.
Not sure what advice to provide about the potential of a student installing a keylogger on a computer in a classroom?
A long availability period (like a week) provides opportunities for enterprising students to exploit the issues with passwords to see and research questions in advance. Instead, a quiz with a short availability period like an hour means less time to go look at the other account, record the questions, research them, then go back into the proper account and take the assessment.
Instructors should use custome questions. Students can obtain questionss provided by publishers in ePacks or with textbooks from previous students, the same textbooks the instructor received, or even web sites online which sell the information.Â
High stakes testing ensures students are looking to cheat. When the value of questions is high, these easier methods than knowing the material ensures a war between students and instructors over cheating. Of course, lowering the value of the questions increases the workload of the instructor.Â
