- not seen the goals» (?)

- Many topics where left out. E.g: security policy....» (No, not at all)
- The exam did not cover all aspects (e.g Information hiding, steganography and covert channels, UNIX security). On the other hand, some questions were too specific (like dealing with Kerberos details). Furthermore, the exam mainly checks whether the student has learnt a lot of terms by heart by asking to give definitions.» (To some extent)
- The yes/no-question was in my opinion not well suited to check if one understood the CC-topic.» (To some extent)
- In this sort of "overwiew" course, an exam about specific details like this one does not verify the understanding that well. An exam with problems to solve, "what concept to apply here?", "give a solution to this problem" etc. would have been a better way to measure results.» (To some extent)
- Examination assessed the reaching of some goals, while the laborations saw to other goals.» (To some extent)
- The grade definitely tells if I have succeeded :)» (Yes, definitely)
- becuase the time was fewer than that i can finish book» (I don"t know/have not been examined yet)

- Kind of easy labs, the most time and effort was to answer the questions, but the actual work in the lab was minimal» (Some extent)
- Lab1 helpful, but timeconsuming Lab2 interesting, less help for learning Lab3 poor» (Some extent)
- you can cut short each lab and increase number small labs, that perhaps give us a broad idea!» (Some extent)

- What coursebook?» (?)
- Papers seemed outdated, for example in one lecture, there was a reference to a paper that stated that the MTTF could be over 5000 years for a program, the research was from 1984. Since computer science and programing languages is a very fast growing field i find it hard to believe that 24 years old research is still accurate. Handouts was also pretty old, it would be more intresting with more up to date information. » (Small extent)
- I think the book is a very bad choice and I regret very much, that I spent so much money for it (not because it was so expensive but because it was so bad). I think it is ill-structured, bad in explaining things and very often too informal when it should be formel and sometimes trying to be formal where it is not necessary and therefore missleading. Many of the illustrations could be made much better, too.» (Small extent)
- No coursebook» (Small extent)
- The book is very hard to read, it isn"t complicated it just doesn"t feel motivating. » (Small extent)
- A book with 781 pages is much to read. Subtracting excluded parts, there still remain about 600 pages. Maybe tighten reading instruction?» (Large extent)
- The book provided a lot of information.» (Large extent)
- But I did not buy the book - everything was accessible from the net ,)» (Great extent)

- Laboration 2 took sevral weeks to get back...» (Very badly)
- it took very long to get feedback on lab2, forcing us to spend extra time at the very end of the course.» (Rather badly)
- it was ok. BUT lab registration did NOT work. PLEASE put it on studieportalen. This is a university of TECHNOLOGY - COMPUTER science department. Sharpen up!» (Rather badly)
- lecture notes etc was pretty good. Lab administration was not very good, it took very long time to get the labs corrected and the handin form was bad, for example why should you sign up to a group using the student portal but sign up for a specific lab occation using a hand written paper, why not use the student portal for that also?. One more thing, why doesn"t lab handins use the fire system? It is so much easier.» (Rather well)
- The home page could be made more functional. For example with links to slides, downloads and specially the lab page at a left frame or at the top of the page!» (Rather well)
- Well organized, yet we had to wait a long time for the result for Lab2.» (Very well)
- Everything was perfectly clear.» (Very well)

- I worked with an international student who had read 5 years on another university, this student did not know any programming (even though previous program was software engineering) at all so I had to teach which held me back a great deal.» (Rather poorly)
- We actually did not have the opportunity to get to know other students. People from same nationalities were grouped together and we did not have the chance to use other students" knowledge and experiences. As an example I had never worked with Unix and Linux before. Neither did my partner! So we had a hard time learning to use it alone! But if both of us was grouped with a person who knew it, we could have a better outcome. I mean it was better if the lab grouping was random.» (Rather poorly)
- Please make random groups for labs, otherwise everybody stays with the students from his/her home country.» (Rather poorly)
- Work groups with teacher assistens would be good» (Rather well)

- More excersises and harder laborations!» (Too low)
- The workload to follow the lecture was not too much, however what had to be learned for the exam was much more and often in my opinion not relevant (remembering abbreviations I probably will never need anymore - even if so, could be looked up fast).» (Adequate)
- Alot of material to read in this course, some chapters in the book are not fun at all and not easy read but overall it"s ok» (High)
- Labs, reports, large book» (High)
- I would say high but adequate. Since it was an introductory course it had to have such a workload.» (High)
- Especially during the last weeks.» (High)
- Because of my partner.» (Too high)

- I did not study any other course so..» (Low)
- I had an extra course left from bachelors.. else, it is WAY to low speed.» (Adequate)
- Especially during the last weeks.» (High)
- Have choosen the wrong courses :)» (Too high)
- Because of my partner. International students who cannot program (or miss vital skills about the program) should not rely on other students to teach them and get free rides.» (Too high)
- Since I wasn"t familiar with the quarter based study period I always had problem with estimating the required time for study! But I finally learned.» (Too high)

- Too slow, sure it"s the first security course on chalmers. But most of the students are in their 4th or 5th year so you can demand some prior knowledge in the field. The first 5-8 lectures felt like basic repetition» (Fair)
- Some parts in the beginning of the course was good, but the latter parts was in my opinion rather bad. For example the CC-part was far too big, in my opinion CC could just be mentioned, not going so deep into the certain expression of it, i do not think learning acronyms is a good way of learning something. I also think that the security modelling part is quite diffuse/abstract and hard to put in the context.» (Fair)
- I think the course and especially the exam require too much memorisation and too less understanding.» (Fair)
- Very interesting and important topic - but the approach could be better: Although it is intended only to give an overview, a more scientific approach to the presented details would sometimes help: When distinguishing between different types of attacks for example there was no good definition for them that stated clearly what is a unique property of each of them. In other topics often bulleted lists were presented that distinguished the topic on different dimensions at the same time.» (Adequate)
- basic good to have knowledge. You are supposed to know these things. Skip the object system model though.» (Adequate)
- Interesting, good teaching» (Good)
- Both a difficult (because many many concepts to acquire in a few time) and excellent course (very rich, good for starting in computer security world).» (Good)
- A good introduction course for computer security.» (Good)
- Erland"s a very good teacher. He"s hat-in-hand, knowledgeable and caring.» (Excellent)
- I learned much more than I expected before the course started.» (Excellent)
