Thank you for your response.
In theory, yes, I am able to modify Security Shepherd. The thing is that Security Shepherd is very complex and was written in Java. So it would take me much longer then the time of my internship to learn the Security Shepherd code.
I think I will specifiy my question a bit. So, I want usernames and userscores from the Security Shepherd databank (which I have access to) being displayed in Moodle. (This can just be an extra page and does not necessarly have to connected to a Moodle useraccount). In an ideal scenario the user from Moodle and Security Shepherd are interconnected, but I'm afraid I won't have the time for that.
Another solution is to have a quiz in Moodle where users just answer a few questions about Security Shepherd. One of the questions would be: "Choose your username and score from the list with which you practised in Security Shepherd." --> This way the quiz is used as some sort of survey and the teacher and admin get a nice overview.
I hope my question is clear and that you are able to help me. I have a limited time in completing this part of my internship so if it is not possible, just tell me and I will talk with my supervisor about it.
Thanks in advance!
