Securing HPC: Deploying Low-cost, Open-source Multi-factor Authentication at Scale

Time 10/17/17 02:30PM-03:20PM

Room Seacliff A

Session Abstract

Multi-Factor Authentication (MFA) provides an extra layer against bruteforce attacks and compromised credentials, but can potentially be cost-prohibitive beyond a few hundred users. Texas Advanced Computing Center (TACC) has implemented a unique MFA solution for their production resources using open-source components with per year cost scales of pennies per user. For those universities and institutions considering their own transition to MFA, important considerations and necessary customizations that are critical in an HPC environment are discussed. We present strategies for large-scale deployment and reflect upon lessons learned throughout our first production year. This session will reveal the decisions made that have taken us on this path, the back end that we have selected and built, and how we provide our users with the choice between soft tokens, hard tokens, and SMS tokens -- all with zero licensing costs.
