In this module, we discuss the definition of the authentication, the types of authentication credentials, and the authentication process and related requirements. we learn the Role Based Access Control, short for RBAC, which is an security approach to restricting system access to authorized users and to help specify organization's security policies reflecting its organizational structure. We use Docker Universal Control Plan and AWS IAM access control as examples for illustrating how RBAC simplifies the access control specification and management.

In this module, we discuss PMI Privilege Management Infrastructure for managing the authorization of privileges within a system. We use attribute certificates as an instrument to associate access rights of the resources/services in the system to the identities or roles of the intended users of the system. We compare the differences between the PKI, the public key infrastructure which is focused on identity management, with the PMI which is focused on the management of the privileges authorized for users. We discuss their difference usages for the access control of the system. We then present the XACML, which is an eXtensible Access Control Markup Language (XACML) for specifying policies. It is an attribute-based access control system (ABAC), where attributes associated with a user or action or resource are inputs into the decision of whether a given user may access a given resource in a particular way. An implementation of ABAC system using Sun’s XACML 2.0 Java reference implementation called ENFORCE is then presented as an example.
