  Given the significant dangers of LHC operations, access control to the accelerator controls system is required. This paper describes the requirements, design, and implementation of Role-Based Access Control (RBAC) for the LHC and injectors controls systems. It is an overview of the two main components of RBAC: authentication and authorization, and the tools needed to manage access control data. We begin by stating the main requirements of RBAC and then describe the architecture and its implementation. RBAC is developed by LAFS a collaboration between CERN and Fermilab.

  CERN’s Accelerator Controls group launched a project in 2003 to develop the new CERN accelerator Real-Time Front-End Software Architecture (FESA) for the LHC and its injectors. In this paper, we would like to report the status of this project, at the eve of the LHC start-up. After describing the main concepts of this real-time Object Oriented Software Framework, we will present how we have capitalized on this technical choice by showing the flexibility through the new functionalities recently introduced such as Transactions, Diagnostics, Monitoring, Management of LHC Critical Settings, and Communication with PLC devices. We will depict the methodology we have put in place to manage the growing community of developers and the start of a collaboration with GSI. To conclude we will present the extensions foreseen in the short term.
