Abstract

Network security is concerned with protecting sensitive information, limiting unauthorised access, and reinforcing network performance. An important factor in network security is encryption. Internet Security Protocol (IPSec) is the de facto open standard for encryption and replaces the older Cisco Encryption Technology (CET). Both encryption protocols are typically implemented and managed using the text based Command Line Interface (CLI). A graphical user interface (GUI) is available; however, it is not routinely used. Regardless of whether the CLI or GUI is used, both encryption suites are complex to implement and manage. State Model Diagrams (SMDs) were developed and successfully used as the pedagogical foundation of internetworking technologies. SMDs integrate pertinent output from devices and protocol finite state information. SMDs are modular and hierarchical models thereby providing top down deconstruction as a cascaded structure. In terms of ease of use, hyperlinks may be used to navigate between different state tables and diagrams. Moreover, as hierarchical model characteristics allow technical detail to be presented and integrated to assist in managing devices. In this paper, SMDs were used to evaluate CET and IPSec via experiments in order to determine their potential value as network management tool.
