Towards Modelling Information Security with Key-Challenge Petri Nets

2009

Our global information society is based on distributed wide-area networks. Network security consists of the provisions made in an underlying computer network infrastructure, policies adopted by the network administrator to protect the network-accessible resources from unauthorized access, as well as continuous monitoring and measurement of the network security's effectiveness. In this paper, we describe the use of Petri nets in modelling network security. We propose a new hierarchical method for modelling network attacks and evaluating effectiveness of the corresponding defences. Our model is called Key-Challenge Petri Net (KCPN).

A CAPWAP-Compliant Solution for Radio Resource Management in Large-Scale 802.11 WLAN

2007

Recently, the impressive success of the IEEE 802.11 WLAN technology has dramatically changed the role of the wireless connectivity provisioning. Born as a wireless extension of small office or home networks, todays the WLANs are getting more and more popular as a large, even metropolitan, area networks. The deployment of large-scale WLANs has some critical issues, because of the lack of coordinated management functionalities among the network nodes. In this paper we briefly describe the CAPWAP architectural solution, for centralizing some control and maintenance functionalities in large scale WLAN, by guaranteeing the interoperability between network nodes provided by different vendors. We …
