A new model for monitoring intrusion based on Petri Nets
Computers and the information they process are critical to many organizations' ability to perform their mission and business functions. It therefore makes sense that executives view computer security as a management issue and seek to protect their data which are stored in these computers. Presents a main objective of introducing a modeling design and verification of the monitoring part of common intrusion detection framework (CIDF) using Petri Nets. To enhance the security of a system by monitoring system activity and detecting a typical behavior, statistical unusual behavior must be found in the observation of the system. Such a monitoring system will be capable of detecting intrusion that could not be detected by any other means. These systems that do collect audit data are the only way to build a real secure system which is the most important part of the network. Presents a proposed model of the monitoring part of the CIDF based on Petri Nets modeling technique. Tests the proposed model using the Petri Nets properties.
