A Flexible Security System for Metacomputing Environments
A metacomputing environment is a collection of geographically
distributed resources (people, computers, devices, databases) connected
by one or more high-speed networks and potentially spanning multiple
administrative domains. Security is an essential part of metasystem
design--high-level resources and services defined by the metacomputer
must be protected from one another and from possibly corrupted
underlying resources, while those underlying resources must minimize
their vulnerability to attacks from the metacomputer level. We present
the Legion security architecture, a flexible, adaptable framework for
solving the metacomputing security problem. We demonstrate that this
framework is flexible enough to implement a wide range of security
mechanisms and high-level policies.
