Analysis of Intrusion Detection and Prevention Systems as Queueing Services

摘要

The paper presents an analytical model to study the performance and availability of queueing systems with finite queue and two service phases. The first phase has the exponential distribution of service time, while the second one has the hyperexponential distribution. The analytical results obtained are verified using discrete-event simulation. A few numerical examples for varying the service rates and arrival rates are given. The results presented in the paper can be used for analysis of the intrusion detection and prevention systems (IDPS).
