Stateless Security Risk Assessment for Dynamic Networks

Abstract

Emerging networking technologies, such as cloud and Software Defined Networking, provide flexibility, elasticity and functionalities to change the network configurations over time. However, changes also impose unpredictable security postures at different times, creating difficulties to the security assessment of the network. To address this issue, we propose a stateless security risk assessment, which combines the security posture of network states at different times to provide an overall security overview. This paper describes the methodologies of the stateless security risk assessment. Our approach is applicable to any emerging networking technologies with dynamic changes. ? 2018 IEEE.
