1. Cloud Usability and End User Taxonomy Dr. Karuna P Joshi IAB Meeting Research Report June 13, 2013 12/18/12CHMPR IAB 20121

2. Introduction Current Cloud Computing standards aimed at Administrators, Developers, IT Managers Disconnect between the End User’s capabilities and Cloud Provider’s Expectation – Device type (Mobile, Fixed) – Security features – Privacy settings Project to determine Usability standards for Cloud Consumer/ End User With NIST’s IAD division’s Usability and Visualization group 12/18/12CHMPR IAB 20122

3. Objectives Goal 1: Develop a Reference Architecture for Cloud Usability Goal 2: Build a taxonomy of Cloud Consumers/ End Users Studies referred 1.Survey completed of 40 people on Privacy perception of Online applications 2.Survey under way of 120 people using social media application (Facebook) 12/18/12CHMPR IAB 20123

4. Development Approach Broad High Levels of the Ontology identified Cloud User – expert, novice, standard Cloud Service – IaaS, SaaS, PaaS User Devices – Fixed, Mobile Service Security Service Privacy Attacks – Privacy Attack – Security Attack 12/18/12CHMPR IAB 20124

5. Persona / Use Case Determine Persona of Cloud End Users – Persona 1: Novice Cloud User – Persona 2: Expert Cloud User – Persona 3: Standard Cloud User Determine Use Cases – Use Case 1 – Social Media site Hacking – Use Case 2 – Same Cloud-User, Multiple site Hacking – Use Case 3 – Same Cloud-User, Multiple devices to access cloud – including mobile and fixed devices. 12/18/12CHMPR IAB 20125

6. Evaluation Will be reviewed by NIST Cloud Computing team Will be reviewed by NIST Security division. External reviewers Will be discussed with the cloud computing working groups 12/18/12CHMPR IAB 20126

7. Status Currently developing End User Reference Architecture Taxonomy under review with NIST cloud computing team/ security team. 12/18/12CHMPR IAB 20127
