1 Towards A Theory Of Insider Threat Assessment Authors: Ramkumar Chinchani, Anusha Iyer Hung Q Ngo, Shambhu Upadhyaya International Conference on Dependable Systems and Networks 2005 (DSN 2005), pp , 2005 Present by : Zhongxia Ma Department of Computer Science University of Auckland

2 Summary  Gives readers some background information about insider threat  Introduces the authors’ model(key challenge graph)  Uses key challenge graph to simulate the insider threat  Analyses the possible insider attack strategies  Compares and contrasts the key challenge graph with other relevant models

3 Appreciative Comment Paper gives enough background information about insider threat  Explains what insider threats are, what damages the insider threats can cause, and why detect insider threats is hard.  Readers get a very clear idea of what the paper is going to talk about.  Readers also get some basic knowledge about insider threats.  The words like “FBI/CSI” also attract readers’ attention.

4 Appreciative Comment T he key challenge graph model is good  Easy to understand, easy to remember  Widely used (simulate social engineering attacks)  Compare with other relevant models, the key challenge graph is batter for the insider threat problem key Key Start vertex Target vertex Middle vertex Key challenge

5 Critical Comment Misleading terminology  Key (here means information on a vertex not the cryptographic key)  Key challenge, a authorization process. (key means an cryptographic key )  The key to the key challenge key Key Start vertex Target vertex Middle vertex key challenge

6 Question?  If a student plan to hack into Clark's computer to change his grade from a lab computer, do you think he can success? key Key Start vertex Target vertex Middle vertex Key challenge
