Security Architecture Analysis

When I have been looking for work related to my research I stumbled over this survey from the Australian government: A Survey of Techniques for Security Architecture Analysis. It's quite an interesting survey. Only too bad that it is rather old from 2003. However, It contains a lot of interesting stuff and I have not found any other paper that covers as much work in this field in the same context. The abstract of the survey says (my layout and emphases):

This technical report is a survey of existing techniques which could potentially be used in the analysis of security architectures. The report has been structured to section the analysis process over three phases:
  • the capture of a specific architecture in a suitable representation,
  • discovering attacks on the captured architecture, and
  • then assessing and comparing different security architectures.
Each technique presented in this report has been recognised as being potentially useful for one phase of the analysis. By presenting a set of potentially useful techniques, it is hoped that designers and decisionmakers involved in the development and maintenance of security architectures will be able to develop a more complete, justified and usable methodology other than those currently being used to perform analyses.
Does anybody know of any other work that covers all the three phases above?

Sweden the third most used country for cyber crime

Sweden has according to a Swedish newspaper a lot of servers that are used for crime acts. Third position this year, last year we has the second position...

Kriminella avancerar på nätet

Chockhöjning av nya virus...

Well, I hope this might increase the funding for computer security at large and specifically intrusion detection.

The misuse of intrusion detection

The same methods used for intrusion detection can also be used for detecting anything. The EU Justice Commissioner Franco Frattini wants to forbid searches for terror words such as "bomb" and "kill" and "terrorism". You might start to wonder what EU is going to become.

Visualization

Anton Chuvakin points to this funny link about visualization. Especially the statement:
"Chart-based encryption -- data goes in, no information comes out" is funny. This is worth keeping in mind when thinking about what to visualize in a security setting. In my work we want to visualize potential intrusion activities and attacks at a network level. We want to give the user a situational picture ("Lägesbild " in Swedish) of the activities at different nodes in the network. In order to do that, we have to use visualization to communicate in an understandable way.
