Main advantages

Thanks to the GENIUS and EnginFrame (developed by the Italian Company NICE srl) user can

• Interact with files on the UI • Send jobs to the Grid • Manage the data belonging to the given Virtual Organization.

Moreover:• No needs of a particular Operating System and middle-ware

running on the client side

5

Security Services 1/2

• In order to guarantee a secure access to the Grid, GENIUS has been implemented with a multi-layered security infrastructure.

• All web transactions are executed under the Secure Socket Layer (SSL) via HTTPS.

• The user has to have an account on the User Interface machine where GENIUS is running

6

Security Services 2/2

• Two access modes:

Grid authentication in GENIUS is currently based on the concept of user credentials delegation implemented with MyProxy

When the user wants to interact with the file-system of the UI, performing operations with his files, he gets prompted for the username and password of the account on that machine.
