Replacing POSIX authentication, towards a new Identity and Access Management for HPC
- Maxime Martinasso (CSCS)
Description
Since the early development of Linux-based operating systems, the management of identities following POSIX standards has shown very few improvements. Today, HPC centres continue to use Linux-inherited POSIX standards for managing their users identities. With the development of web services and applications, a new set of concepts and standards grouped inside the name Identity and Access Management (IAM) have been developed to manage identities and roles. Applying IAM to HPC improves user management, roles definition, security and enables a simpler exchange of workflows from Cloud to HPC or vice versa. This talk showcases the application of such an IAM authentication concept to access HPC systems and discusses the benefits and the difficulties to integrate other IAM concepts to access HPC centres.
