The Evolution of Identity and Access Management
Peter Cooke at Bloor Research recently wrote this interesting article on the history and future of IAM.
Single sign-on solutions (SSO) have been developed to help with this issue. SSO systems enable users to log in once only and then be automatically authenticated when they attempt access to other resources. There are a number of technical solutions to this problem, each with its own advantages and disadvantages, including Kerberos, password management and password synchronisation. The reason for the number of solutions is down to the complexity of implementing each and the wide range of run-time environments where some solutions cannot be supported.
