5. Do you think that there are parts of the course that overlap too much with other courses? Do we need to change? Or should the other course change?

- This course schedule is apt and flexible especially the labs. I don"t find a need to change its schedule.»
- no»
- Cause I never studied network or communication security related courses before, I have no idea.»
- Some overlaps with Computer Security course but only what couldn"t be avoided, given the similarities of the courses.»
- yes, but do not have to change, it is a very good course»
- I don"t think they should change. It could be viewed as reinforcement of material and continuity and relation of one discipline to another.»
- I think course syllabus is pretty fine. It is organized rather better.»
- i got a one course about net work just in bachelor but this topic was new for me»
- No.»
- With CompSec, Kerberos, IDS, Firewalls...»
- The course is fine as it is.»
- The lecture on cryptography is unnecessary, the Crytpo-course covers this fully.»
- Don"t need to change, but really need some pre-knowledge about internet technology.»
- a bit overlaps is necessary and makes us feel that what we have read before are really useful and an attacker can really use it (specially I notice Wireless encryption problem) like using ARP packets in WEP cracking »
- no, it"s good»
- No»
- No»

- The professor"s English is really good. But I am not good enough to catch every word. So I always can not understand the content of lectures fully.» (To some extent)
- Sometimes lecturer speaks too fast, easy to miss some detail.» (To some extent)
- Too much content on each lecture. Fewer contents with more detailed on some slides would be nice.» (Large extent)

- Not really covering all the subjects as many additional papers were given.» (Yes)
- I do not find it useful, neither for the Network Security course nor for the Criptography one. Also, many chapters (eg. part of User authentication, DoS, Firewalls, Intrusion Detection) are found in the "Computer Security - Principles and practice" book not in the one I bought. It is also quite expensive considering that I use it only for max. 7 chapters» (Yes)
- Some parts are not clearly described.» (Yes)
- Doesn"t worth it. Book was used for too few chapters. Having the book as ebook at library would be nice. Or maybe just using additional content and not the book.» (Yes)
- I did not get much help from the book. Lot of Network Security topics are missing, and the topics in it may be hard to grasp, they need to be read very carefully, details often only given once despite the rich amount of text. The book is better for Cryptography I guess.» (Yes)
- The book is okay, I was a little irritated that there is some "online chapters only" for the course, but that subsided when I saw that they were availiable as pdf:s for offline reading. It"s a big plus that it is shared with the Cryptography course.» (Yes)
- That it was a bit waste of money. I take the cryptography course last year so I had not use of that part. I also had the book in computer security so lots of things was covered in that book. Aftewords I am thinking that it had been enough with that book and the reading material on internet.» (Yes)
- The book was good overall. Always annoying with web chapters though. Another critique is that the level of detail was quite varying between the different chapters. Some (SSL and IPsec if I remember correctly) went quite deep while other (IDSs and firewalls) were comparably of a more high level.» (Yes)
- Did not read it alot.» (Yes)
- i got a pdf version» (No)
- I read pdf version. But very close to the lectures. Just as help to understand. And I need to search a lot over internet to understand fully.» (No)
- too expensive for just one topic, and documentation can be found on the internet» (No)
- this course was not main subject for my program bcz my program is software engineering » (No)
- I used the one from the Cryptography course.» (No)
- I find most of my reading material online, google books, free security reports, et c.» (No)
- Slides are better» (No)
- Too expensive and I can"t carry it home» (No)
- Not worth it.» (No)
- I think, I can find everthing I need in internet. However teacher"s help can be usefull ( for example suggestenig special links) » (No)
- My experience from books from courses like these is that they write a lot but give too little information per page. Reading all the pages in the book just decreases one"s chance to get a good grade, or to even pass. It is too time consuming!» (No)

- A lot of technical problems in this lab with things not working properly. ICMP filtering etc. » (Grade 3)
- complex and difficult » (Grade 4)
- As said before, I like that the lab assistants takes some time to really explain things. And even if it feel horrible when they asks so much questions it is good for learning. Of course this is for all labs.» (Grade 4)
- I"m impressed by the labs in this course. They were instructive, up to date and balanced when it comes to workload. WELL DONE!» (Grade 5)

- We were expecting to some more elaborate detections (Xmas scan attacks for example), not just string match in payloads.» (Grade 2)
- Didn"t know at all what to look for when we got there. The TAs should give some hints in the beginning of the lab that we were supposed to look for some strings in the data payload etc. That would"ve saved me 3 hours :/» (Grade 2)
- Perhaps more focus (questions?) on identifying the attacks to what was the intended info gain by the attacker, than just state facts?» (Grade 3)
- The subject is really interesting but all studets are confused because lab documentation and instruction was not clear enough. and We don"t know what to expect. we can learn more ebout IDS:s but ambiguous instruction slow down the lab speed» (Grade 3)
- I"m impressed by the labs in this course. They were instructive, up to date and balanced when it comes to workload. WELL DONE!» (Grade 5)

- My group had to wait for over an hour for help in the firewall lab. This despite there being two (Laleh and Arne) TAs available. This is a lot of time for a laboration which is supposed to take four hours in total!» (Rather poor)
- Thomas: you could stay in the lecture room for 30sec longer before you go. Some ppl want to ask small questions after the class.» (Rather good)

- It would be nice if there were some guest lectures from area experts.» (Good)
- The only thing that is keeping the course from excellent is the exam. It is really hard to know at what level you want the answers. E.g. 5a Explain on a fairly high level how this protocol works... What is a fairly high level :). Maybe i"m to much of a stiff engineer for these kind of exams...» (Good)
- Very good teaching which was very well connected to the literature.» (Excellent)
- Labs assistants are not enough to help students where they stuck on a problem. and each student has to wait for a long time to ask a question» (Excellent)

18. What should definitely be preserved to next year?

- The labs»
- labs»
- the professor of course:)»
- labs»
- The labs are very good and should be kept for next year The presentation slides are well organized and contain just the right amount of information»

- Wireless security, scanning»
- Guest lectures from company, video clip materials. »
- Everything»
- The labs was a great complement to the lectures, where most of the course was covered.»

- Both the teaching and study material was of very high quality. Pierre was great as TA as well.»
- labs»
- Think it should be kept the same»
- The Teacher who took the course»

19. What should definitely be changed to next year?

- maybe make the labs more diffucult? not sure»
- labs administration, processes not personnel»
- The course book»
- Nothing»
- i think adding more slid and describe tiles more »
- Materials, some labs (3 and 4) should be change. A lab about WEP/WPA would be better than lab 4.»
- less redundancy with CompSec, more new things»
- I would actually have the cryptography course as required prerequisite.»
- The technical problems with the laborations need to be solved. Would be nice if everything was confirmed to work before the allocated time slots.»
- The lecturer could be a bit more interactive. The slides are not extremely informative. I would recommend to use the board to explain some things better in the lectures, otherwise they become quite boring. Also some nice figures in the slides would be great.»
- More time for revision after the teaching»

20. Additional comments

- no»
- a fairly good course»
- good luck»
- Overall, I consider it a good course I do not find it entirely suitable for the Communication Engineering master program »
