This is the small initial assignment that you need to complete and submit at latest 10 September or you will be un-registered from the course. It will give you a chance to think about what you know about IT Security and share experiences and ideas with other students on the course.
You should submit a small report. The report should be at between 300 and 600 words long. The report should have two sections and be submitted directly as text into MyMoodle.
The two sections you should address are:
-
Describe one or several IT security incidents that you personally have experienced.
Write about what happened and what consequences there were. Think that an incident is anything that violates a security policy (or for a private person anything that you think is an undesired activity). It can be forgotten information, lost devices, direct attacks etc. -
Media report almost daily about different IT security incidents. Think back about what you have seen in media in the last few months. Reference these news and have a short discussion about the incident.
Do not write your name in the report text since I might share the text with the other students on the course.
The assignment is mandatory and you have to submit at latest Friday 10 September. Failing to do that will lead to you being unregistered from the course.

For those of you who signed up for the home exam the rules are as follows:
The exam will be published here when the exam time open and you should publish your answers before the exam closes. Deadlines are strict!
As soon as the exam time start, you can fetch the exam papers with questions here. I will be available on Slack on an off if you have any questions during the exam. After checking the submitted exams I might ask some of you to do a follow up oral exam. This is based on suspicion of plagiarism and/or if you are close to pass the exam. I will make a schedule for this as soon as I know who will have to take the oral exam.
Please note that I will use an anti-plagiarism tool so make sure you write your answers using your own words. No copying of texts from textbooks or internet!
-
Here, you will be able to post late submissions of reports and reports that did not pass in the first submission round.
