Abstract

Access control services in the cloud require
defining which users, applications, or functions can have access to which data
to perform what kinds of operations. There are thus three dimensions: (1) which
users can (2) perform which operations (3) on which data. We speak of: (1)
principals (i.e., users or roles), (2) privileges, and (3) objects,
corresponding to these three dimensions, respectively. The act of accessing
gives rights and privileges such as using or releasing data, modifying the access
rights or accomplishing certain tasks. Permission to access also requires
identity management. Research studies identify the existence of dependency
between usability and security, and that there exists a conflict between the
two, for which trade-offs are difficult to evaluate and engineer. This paper
proposes a novel methodology for assessing the usability of access control
services while ensuring that security requirements are met. The proposed
methodology assists in integrating the experience of both security and
usability experts by using different Human Computer Interaction methods as a
way to identify the usability and security problems in access control security
services in the cloud, and capture solutions to resolve such problems.
