Computer Science Case Study [2014]

Recommended Posts

Hey guys!

We have a new syllabus (as I'm sure all of you know :P) for 2014 and I was wondering whether we could all band together and think of a few possible questions they may pose us! If we manage to think of a lot (especially for question 4) we would be much better prepared for this paper, which in my opinion is kinda hard to prepare for. Here's how they structured the specimen paper:

1. Defining terms

2. Applying the knowledge from the case study

3. Extending that knowledge a bit more

4. An essay using knowledge that you researched; for this one you have to have researched and done much more than just reading the case study and learning the terms, if you just did that you wouldn't score too much on the essay.

Here is the specimen case study:

http://xmltwo.ibo.org/publications/DP/Group4/d_4_comsc_tsm_1201_1/pdf/spec4comschp3engtz0xxcs.pdf

Question sheet:

http://xmltwo.ibo.org/publications/DP/Group4/d_4_comsc_tsm_1201_1/pdf/spec4comschp3engtz0xx.pdf

Mark scheme:

The above links seem to have gone broke... here's another link (that includes papers 1 and 2! huzzah!): Click me!

Here are the questions people suggested may be asked:

1.-Not needed, its a definition so we'll assume this one will be like that as well-

2.-Applied knowledge, so not really needed-

3.-Extending knowledge, questions here would help!-

How sophisticated would the network security of a school have to be? Why?

4.-Research, extremely useful if you think of a few. Some possible essay questions requiring research are needed!-

How would you be able to prevent DoS attacks? What shortcomings and benefits do these have? (just a prompt, researching this would undoubtedly help for the essay though) (by David Kroell)

What software, hardware, and other resources do man-in-the-middle attacks use? How are these implemented by hackers?

For the research question, as we can't be certain, reading up a lot on net security and so on might help, here are a few articles and web pages I've managed to scrounge up. Would be nice if you could provide some as well.

Possibly useful news articles and other information:

Thank you theilsanne for your mock paper 3 and revision doc! Attached as well.

Here's a glossary I had for the case study terms, not fool proof but should be good enough. I've let you guys edit it, feel free to edit a definition or add an article!

(no longer editable in advance, so that people don't vandalize it while I'm not here!)

Hopefully we can think of a few useful ones :D

Cheers!

P.S.: Mods, could this be stickied instead of the thread for the case study for 2010? Thanks.

Obviously they will ask us about defining terms.

I think that one of the questions that they will undoubtedly ask us will be how to prevent certain Denial of Service attacks.

Smurf attacks and such, with advanced knowledge of networking.

There will also be some long-answer question I bet that will ask us to evaluate certain methods of preventing either DDoS or DoS attacks.

I will be doing research and following this forum.

Added a q4 we used for our mock.

And I'm assuming my plea for this to be stickied has fallen to deaf ears... although I see no reason for why it shouldn't be, considering the 2010 one still is.

Thanks David Kroell! I added your suggestions the day you put it up, but I refrained from replying until I got something else to put in as well. Hopefully more people will contribute in the coming 2 months before the exams.

Firstly, thanks for opening up this thread!

Here are a few resources I'm working on -

  • mockP3-2013caseStudy.docx is what we used on our mock exams, courtesy of Dave Mulkey -- I've worked through it; not sure about my answers but tell me if you guys would like to see them?

  • Case Study Condensed.docx is exactly what it's named -- feel free to add to it? :)

I also have a glossary (but I'm sure everyone's got their own, of the keywords listed at the end of the study and a couple more)

Hope these help a little! Please add to it if you can!

I've got a glossary actually, I'll find it and put it up ^^ Thanks theilsanne! It's been ages since someone posted so I was assuming everyone did their own thing lol. And thank you so much for that paper! My teacher put his version on as well, I've included that, if you don't mind I'll be putting those questions on the OP as an attachment. Did your teacher by chance include a markscheme? I'll look for one my teacher made, and include the other questions of our mock. Yours are a different format though from the specimen :o the original website for the specimens seems dead... but I was pretty sure we have a sort of essay to answer...? As in, we use all the information we gathered on the case study and write an essay on the day on some topic we don't know, using the info we gathered.

And here another futile attempt: Mods, can someone PLEASE sticky this instead of the 2010 one? I have no idea who mods here, so idk who to PM. The original theme seems to have crashed and I'm stuck on the mobile version.

Yep, no problem! Here's my glossary. Hope it helps!

We didn't get a markscheme for that paper but we DID go through it in class, sort of -

It'd be cool if you guys looked over the stuff and helped me out with anything that seems off or inaccurate :) thank youu! XeoNight I'll take a look at the glossary and update if needed.

Another good thing is that a lot of topic three can be applied to our case study haha (Y)

Hey guys,

I just came across this PPT which cover various DOS attack types (both, local + remotely stopping services), along with appropriate countermeasures.

Best of luck for the remaining exams (Y)
The end is near :headbang:
