  2. 82. Enforcing Two-Factor Authentication at CERN: A Technical Report on Our Experiences with User Migration
    Adeel Ahmad (CERN)
    02/11/2022, 12:10
    Networking & Security

    During 2022 CERN introduced permanent Two-Factor Authentication (2FA) for accounts having access to critical services. The new login flow requires users to always login with a 2FA token (either TOTP or WebAuthn), introducing a significant security improvement for the individual and the laboratory. In this paper we will discuss the rationale behind the 2FA deployment, as well as the technical...

  4. 93. Update from the HEPiX IPv6 working group
    David Kelsey (Science and Technology Facilities Council STFC (GB))
    02/11/2022, 14:35
    Networking & Security

    The HEPiX IPv6 working group continues to track and encourage the deployment of dual-stack IPv4/IPv6 services. We also recommend dual-stack clients (worker nodes etc). Monitoring of data transfers shows that many are are happening today over IPv6 but it is still true that many are not! Our long-term aim is to move to an IPv6-only WLCG, so we need to discourage the use of IPv4 for data...

  5. 100. Update on the Global perfSONAR Network Monitoring and Analytics Framework
    Shawn Mc Kee (University of Michigan (US))
    02/11/2022, 15:00
    Networking & Security

    WLCG relies on the network as a critical part of its infrastructure and therefore needs to guarantee effective network usage and prompt detection and resolution of any network issues, including connection failures, congestion and traffic routing. The IRIS-HEP/OSG-LHC Networking Area is a partner of the WLCG effort and is focused on being the primary source of networking information for its...

  6. 99. Research Networking Technical WG Status and Plans
    Marian Babik (CERN)
    02/11/2022, 15:25
    Networking & Security

    The high-energy physics community, along with the WLCG sites and Research and Education (R&E) networks are collaborating on network technology development, prototyping and implementation via the Research Networking Technical working group (RNTWG). As the scale and complexity of the current HEP network grows rapidly, new technologies and platforms are being introduced that greatly extend the...
