Ways to exploit online games, more...

I just got through the book by McGraw and Hoglund on "exploiting online games - cheating massively distributed systems". I've tried to extract the most important attack vectors because I found the book rather verbose. And don't expect much "distributed". Most of the attacks discussed are purely local exploits of the game client. But the threat model is quite interesting: The server side needs to trust the game client while being aware that it might be under control of the attacker - so it uses heuristics to find out about the manipulations. This is not a scenario that most business e-services would survive...

Security Enhanced Linux

Security Enhanced Linux is NSA's open source version of a better Linux. The work on SELinux has taken many years (some aspects of the implementation look a bit old-style) but it is an interesting approach towards better host based security.

The following is based on the excellent book about SELinux by Bill Mccarty and concentrates on the concepts behind SELinux and its implementation.

Security Improvements to the Windows Platform

Can the security of a local system be achieved through collaborative services? And what is the price you have to pay for it in the long run? A few comments on Bill Gates talk at the RSA 2005.

Are security laws "immutable"?

and why would somebody say so? A short bit on so called "immutable laws" of security proposed by Microsoft guys. I've used structural text analysis methods to uncover the assumptions behind. It's the typical MS argumentation: the operating system is OK. Systems can't be safe against malware. It has nothing to do with architecture. And it's the users fault anyway.
