A Conceptual Model as an aid to student understanding of Network Security

摘要

Security is amongst the most widely discussed topics in today’s world of high speed networking.Security broadly deals with problems that affect millions of computer users around the worldeither through the spread of viruses, or information theft from personal computers and networkservers. Security issues can encompass large quantities of detailed information which canoverwhelm network administrators. Security systems are traditionally often layered in a topdownmanner. Abstract models could enable administrators to focus upon relevant details whilstfiltering out non-essential details. Such models could also be used in a top-down fashion thuspermitting the control of complexity via recursive decomposition. There are currently manysecurity models used in industry and for teaching students about network security. These modelsare not only restricted to confidentiality, authentication, data integrity, non-repudiation, andaccess control, but also take into account physical and human aspects that can effect security. Amodel based upon Finite State Machines (FSM) and called a state model is proposed as an aid todevice level management.
