Argus

Argus Authorization Service (Argus)

The Argus Authorization Service renders consistent authorization decisions for distributed services (e.g., user interfaces, portals, computing elements, storage elements). The service is based on the XACML standard, and uses authorization policies to determine if a user is allowed or denied to perform a certain action on a particular service. The Argus Authorization Service is composed of three main components:

  • The Policy Administration Point (PAP) provides the tools to author authorization policies, organize them in the local repository and configure policy distribution among

IASA

Institute of Accelerating Systems and Applications (IASA)

The Institute of Accelerating Systems and Applications is affiliated with six departments (Medicine, Physics, Electrical and Computer Engineering, Chemical Engineering and General Sciences) of the National and Kapodistrian University of Athens (NKUA) and the National Technical University of Athens (NTUA). It is open to researchers from the international community and access is determined purely on scientific merit.

CERN

European Organization for Nuclear Research (CERN)

CERN, the European Organization for Nuclear Research, is one of the world’s largest and most respected centres for scientific research. Its business is fundamental physics, finding out what the Universe is made of and how it works. At CERN, the world’s largest and most complex scientific instruments are used to study the basic constituents of matter — the fundamental particles. By studying what happens when these particles collide, physicists learn about the laws of Nature.

The instruments used at CERN are particle accelerators and detectors. Accelerators boost beams
