PERMIS

PERMIS (PrivilEge and Role Management Infrastructure Standards) is a sophisticated policy-based authorisation system that implements an enhanced version of the U.S. National Institute of Standards and Technology (NIST) standard Role-Based Access Control (RBAC) model. PERMIS supports the distributed assignment of both roles and attributes to users by multiple distributed attribute authorities, unlike the NIST model which assumes the centralised assignment of roles to users. PERMIS provides a cryptographically secure privilege management infrastructure (PMI) using public key encryption technologies and X.509 Attribute certificates to maintain users' attributes. PERMIS does not provide any authentication mechanism, but leaves it up to the application to determine what to use. PERMIS's strength comes from its ability to be integrated into virtually any application and any authentication scheme like Shibboleth (Internet2), Kerberos, username/passwords, Grid proxy certificates and Public Key Infrastructure (PKI).
