چكيده لاتين :
We present a flexible hierarchical role based access
control model based on simple and existing technologies that
enables efficient function-level access control, prototyped in a
system called LRBAC1, a Linux kernel module enforcing access
control over program execution. The hierarchical design allows
for easy maintenance of roles and access rights in an organization,
effectively thwarting access control vulnerabilities when
configured using adequate policies. Though the prototype incurs
significant overhead on background and small applications in
current flexible deployment model, it incurs only 3.26% overhead
on user interactions with the system (i.e interactive applications)
and 14.4% overhead on Apache web server.
