PPDRRF: A Feasible Model for Construction of Cybersecurity Systems and Its Application

Abstract

By analyzing the PDR, P2DR, P2DR2 model and the techniques it uses, this paper innovatively adopt RIO (Rate of Input and Output on cybersecurity) in the PPDRRF (Policy, Protection, Detection, Response, Recovery and Forensic) model, and quantitatively analyzes some key technologies of cybersecurity system construction, proposes Cybersecurity System Architecture (CSA) and ensures the smooth progress of cybersecurity construction under resource constraints. Finally, we applied PPDRRF in CSA and realized it in the campus network.
