Survivality Modeling for Quantitative Security Assessment in Ubiquitous Computing Systems
چکیده
Ubiquitous computing is about networked processors, which is constructed not only with one computer but with networks of computers. Security solutions usually lack a clear definition of survivality. Thus, this paper deals with a method of quantitatively assessing the system security based on the survivality. Since a logical step towards modeling survivality is to have a set of requirements first, attack-type modeling is constructed firstly. As the case study, we analyze the TCP-SYN attack and Code-Red worm attack according to both the attack-type model and survivality model.
