Network security monitoring - Intrusion detection

Current technology enables multi-faceted federations to increase the availability of privileged information. Unfortunately, the availability of such information also significantly increases security risks. This paper presents a system design for monitoring the security of an integrated public safety network called Capital Wireless Integration Network (CapWIN). CapWIN is a diverse mixture of public and private networks that share information in order to provide public safety and transportation services for metropolitan Washington, DC. It is imperative that the members of integrated systems such as CapWIN be aware of the security status of the other participants in order to anticipate security breaches and respond accordingly. As of now, there are few means by which the members of such systems can obtain real-time information pertaining to the security status of all other participating parties. The system presented here integrates these disparate agencies by utilizing existing security information available from each agency within the enterprise.
