Quantifying the role of access control in end-to-end network security

Modern day networks consist of a mix and match of technologies with varying capabilities. Securing such networks is a tedious task and demands a lot of contribution from security professionals; however, failing to conduct an in depth and standardized analysis may result in an imperfect network security design. ITU-T provides recommendation for end-to-end network security in its standard X.805 which precisely lays down the foundation for the assessment of network security. Keeping X.805 requirements and the current network in view, the next thing that security professionals face is the correlation of both and its practical implementation. This paper contributes to answer the same and gives a comprehensive methodology for practical implementation of X.805 architecture. Also this paper takes into account the current trend of Network Access Control solution and its quantitative contribution towards achieving the desired goals set by X.805 standard.
