Deploying SLURM PAM modules on SLE compute nodes

Security in High Performance Computing (HPC) environments has always been a proposal of relativity. Striking a balance between implementing an adequate level of security and not interfering with “getting the science done”. In the simplest terms the primary security realms HPC systems and clusters are exposed to are environmental and user facing. More specifically […]

The SSSD, Active Directory, and growing SLES integration

From both feature and security perspectives, integrating Linux systems with Active Directory environments has been a challenge for their respective system administrators and organisations. However, modern Linux distributions include the System Security Services Daemon (SSSD) which addresses many of the legacy shortcomings handily. The daemon uses identity and authentication providers (and other service providers) to […]

Multi-factor authentication (MFA) solutions are becoming the standard for many user facing IT services. Most visibly with web applications, corporate VPNs, self-service portals and online banking platforms to name but a few. Extending MFA to the realm of system administration to harden access to the Linux operating system itself is becoming an established best practice […]
