  1. A Survey of Risk:Federated ID Management in Cloud and Grid Computing Presentation by Andy Wood (P11250192)

  2. Introduction • Cloud (and Grid) computing are the new platforms today. • Working with business partners is more common place in todays connected world. • Managing user accounts across disparate systems is becoming more difficult and costly.

  3. Federated ID Management • Federated ID Management (FIdM) allows for simplified user management across security domains. • Based on a user authenticating to own DS and their ID used to authenticate to remote services through trust relationships. • FIdM is based on not just technology. • Many ways to implement • User centric • Business centric

  4. Federated ID Management

  5. Critical Review - Resources • Keywords: • (FIdM or Federated) and Cloud and Risk. • Resource Databases: • IEEE Xplore; ACM DL; SCOPUS; CiteSeerX and Google Scholar. • Resources: • 673 initial resources. • Reduced to final 18. • 5 Further papers added

  6. Critical Review - Criteria • Criteria: • Primary / Secondary source • Difficulty to implement • Risk type: Security; Liability; Trust; Assurance or Interoperability • Scalability • Protocols • Citation

  7. Critical Review - Findings • Most papers describe similar technologies: • SAML being key protocol for ID transfer • XACML bring key protocol for access control • Key risks: • Trust (with 3rd party); • Interoperability; and • Message security. • Scalability of solutions were good • Difficulty varied and subjective • Olden (2011) describes a typical enterprise benefit with example saving of $4.5m per year.

  8. Critical Review – Risks • Liability • Ensuring lines of responsibility • Assurance • Processes and procedures being followed: • staff vetting; • joiners/movers/leavers etc. • Trust • Fundamental, but difficult to implement • Security • ID theft • Greater exposure than via separate authentication to systems • Message security through exchange of ID information • Interoperability • Some standard based mechanisms such as SAML • Others describe extended or bespoke mechanisms • Potential for large federations to include multiple mechanisms • Higher risk profile • Higher cost for implementation and support

  9. Conclusion • Resources were harmonious in design and risk • Immature area of technology • Still room for improvement • FIdM is more than just technology • Lack of described foundation prior to tech • FIdM is a business enabler • Balance of risk v business enablement • Risk profile has to be aligned to each business
