Automatic generation of extended dependency graphs for network security

We introduce a computational model for networks that is suitable for supporting the administrative staff in estimating the threat that is caused by security relevant events, for identifying possible root causes for these events and for making predictions about the impact of attacks or countermeasures against attacks. We refer to expertise from the network management domain and extend the common methodologies to meet the demands of network security. We also describe how this model can be created and updated in an automatic way.
