FIT5044 – Network Security Week 11 + Review

The final week of new topics for Network Security covered Security for Large Computer Systems. This post will also contain a short review of the FIT5044 subject. The first point to consider when implementing large scale security solutions is the fast moving nature of computer security in addition to the difficulty in change associated with large business networks. Increased integration, particularly with  the availability of inter-organization or publicly available services adds difficulty considering the mutually exclusive nature of security and convenience.

Subject Review:

FIT5044Network Security was my favorite subject of the MIT course thus far. It contains very interesting subject material and introduces students to topics they must independently investigate to gain proper understanding (I think all post graduate subject should subscribe to this). It is proposed that the subject should be a good addition for non-IT students however I imagine this would be quite challenging without some fundamental IT background. I recommend this subject to anyone in the MIT course.
