  1. Torbjörn Wiberg091022, tf-emc2, Roma Campus Middleware Issues

  2. Campus (non-Middleware) Issues • What consequences are there of the fact that there are both campus and distance students on every course • Economy, Efficiency, Roi in focus • We must become much better in calculating and presenting economic consequences of the changes we propose • Both before and after the changes • (How) shall we act on the quick increase of cloud services • Students are involved in many of our business processes

  3. Economy of middeware • How much does it cost to • Issue an identity • Use an identity (or use the AAI) • Reset a password • Loose a student due to .. • slow distribution of account credentials • To high requirements on LOA for initial identification • How much may it cost to… • How much is it worth to have authoritative information in our enterprise database

  4. Middleware Issues • Design and deploy of a campus middleware infrastructure • Increased efficiency and flexibility in the IdM process • Become a federation member, understand and exploit the possibilities with federations • Moving focus from… • authentication to authorisation • directories to metadirectories

  5. Campus middleware infrastructures • = Dir+IdM+Metadirectory+AuthnS+AuthrS • Deployment slow • Metadirectory issues are complicated • Boundaries between maintenance objects are up for discussion whenever there is a need to update or further develop a system component

  6. IdM process issues • Initial identification of distance education students • We have to be quicker – waiting on an identity, as a student or personnel, is time and money lost

  7. Technical Issues • The number of systems integrated increases quickly • raising the requirements on planning the system maintenance process • Group and role management is an increasingly important support function as the number of users of enterprise systems increases • provisioning and attribute services • cms, lms, cscw, business systems

  8. Federation Issues • non-technical issues dominating • what services are of interest • how do we provide what authorisation information to service providers • internal and external service providers

  9. From Authn to Authr • Again: The technology is not the botleneck • Within an institution – each system owner wants system specific attributes for authr • Between institutions – the community is waking up, and becoming aware of the fact that there are more attributes to discuss than eduPersonAffiliation

  10. LOA • There are two perspectives • from the IdP – who wants to say that they issue eIDs at a certain LOA • from the System – who wants to decide what LOA constitutes a risk they are prepared to take for each operation different eIDs • ... and two documents • The NIST Special Publication 800-63 • Reference:M-04-04, Memorandum to the heads of all departments and agencies

  11. Identities on different LOA • How do you upgrade to an higher level LOA • One LOA per IdP or not
