Unified Authentication Scheme

Executive Summary The Unified Authentication Scheme to support all UK University does have potential benefits. The system allows registered staff and students to access the university resource at any computer facilities available, as long as the user has been granted with the access. It creates a centralised control of user access, which can reduce the computer support provided within the local university departments. The scale of the implementation is enormous as the requirements of the system would be different at different university so defining different level of security within each university is difficult. The amount of money that will need to be invested may not be appropriate just for funding a new authentication system. The timescale to migrate on to the UAS system would be difficult to estimate, as the organisation process would be tough to manage. Requirement of the Unified Authentication Scheme (UAS) system · The Unified Authentication Scheme system will become one centralised authentication service that will serve all the UK university computer users. · The system must be secure that it is strong enough to protect against any security threats such as eavesdropping, tampering and vandalism. · The system must provide a reliable service that does not fall over which means a backup or cold stand-by must be available for any unlikely event. · The system must provide a transparent authentication service where user should not be aware of the authentication is taking place to a limit where they only need to enter their password at login. · The system must also be scalable that is capable to provide the service to support large numbers of clients and server over all the UK university. · The system will provide each registered user with one login id with its corresponding password, this will allow user to gain access to the service that has given rights to. Potential Benefits of UAS system · The UAS can become a comprehensive standard over the UK universities. It creates a centralised control of user access that means one centralised database holding all registered user so easier to manage. This can reduce the amount of duplicated information stored of users. · Communication between the same departments of different university can be made easily with the ability to share data and resources. · Allowing registered staff or students to use the computer facilities available in any UK university campus with the one generic user login id and password. · System can reduce the Computer Support provided in the university, in the ideal situation UAS can replace the Central Computing Service, Management Information System and local department computer support, which can reduce the running and staff cost. Potential Drawbacks of UAS system · The UAS system is a very complex and complicated system to implement in a full scale. · The timescale to have all UK university running with the scheme and all people in all universities to be registered with UAS will be impossible to estimate and will be assumed to be a very long period.
