Exam Report for Distributed Information Processing

On that saturday, that I mentioned in my previous post, I had a second exam which was Distributed Information Processing. I found that exam much more difficult than the Information Management exam.

Here are the topics, as far as I can recall them:
– some check question, you have to check if the statement about processes, threads and networks is correct or not
– explain, why the IP adress is not part of the TCP header
– explain why time synchronization is important for computer networks
– explain how digital signatures work and how the receiver knows that the signature is valid
– explain when to use threads and when to use sub-processes

In my opinion the exam was not that easy and not all topics where part of the study material. At least not in that depth. I hope the exam is passed, no matter which grade. 🙂

Exam Report for Information Management

The first exam on saturday was information management. The exam was external and the examiner was Mr. Rainer Keil. I would like to give a short overview on the topics:

– Explain the levels of the reference model of information management by Krcmar
– Explain the information system concept as part of the St. Galler model
– State the possible technologies used in the access network for telecommunication, explain one in detail
– State three GSM hand-over techniques and describe one in detail
– some calculations for a queue system (model)
– Describe the Next Generation Network

The exam included 9 questions, but I’m not able to recall all in detail.

I was surprised that this exam doesn’t felt that difficult and I think it should be passed.

MOOC “In-Memory Data Management” started today

Today the 2015 iteration of Prof. Hasso Plattner’s MOOC In-Memory Data Management has started. You can find the course on the Open HPI webpage.

The course is for free and you can get a certification for the successful participation at the end of the course, if you got at least 50% of the reachable points. I will try to follow the course completely. At the moment I’m watching the first video about the history of enterprise computing.

Maybe the course is interesting for you, too.

Starting with building a penetration testing lab

Currently, I’m looking for informations about how to build an own penetration testing lab. Regarding to my research, I will need to set up a single box with a lot of RAM and then use VMware or VirtualBox to simulate some computers to test with. But setting up a completely dedicated machine for this purpose is currently not in my budget. So I looked what is still available at home. I have an old case in the basement, but the hardware inside is definitely outdated. For example the mainboard cannot work with more than 4 GB RAM. So this is not suitable for the virtual machine purpose.

But I have a relatively modern desktop PC in my flat, which has already 8 GB RAM. It’s not perfect, but I hope it will do the trick to get one or two VMs running on that system. My Kali Linux is a VirtualBox on my notebook, which is running fine there. So, I have my Kali Linux always ready to go and I can start some other boxes on my desktop machine if needed. This should be okay for my first steps. 🙂

next exams in two weeks

The date for the next exams is getting closer. Last week the WBH has sent the timetables for the exam date. Fortunately, both exams I’m going to write are in the same lecture theater. So I don’t have to change the room between the exams. The first exam will be IMI (Information Management) and then follows VII (Distributed Information Processing).

The second module sounds a little bit odd in my translation. In German it is “Verteilte Informationsverarbeitung”, which is also a little bit unfamiliar. In general, it’s again mostly about networking, protocols, connections and the OSI model.

My preparations are doing fine, I think. I started to do some Sketch Notes for IMI to write my own comprehension, but it’s too much to write and sketch, so I stopped this some weeks ago. Instead I will continue with the “classical” learning by reading, repeating, understanding, and answering some questions. This should be okay for IMI. For VII I read a lot of Wikipedia articles about networks protocols and some chapters of Tanenbaum’s “Computer Networks” book, which I finally ordered recently.I expect that I will need this book for my Bachelor thesis as reference.
