The slides shown by Dave Kelsey on WLCG Security in the EGI era are linked from the agenda. He proposed that the MB appoint a WLCG Security Officer and WLCG Security Policy Coordinator. A description of these roles is included in the slides. The MB appointed Romain Wartel as WLCG Security Officer and Dave Kelsey as WLCG Security Policy Coordinator. Romain Wartel, as WLCG Security Officer, will become a member of the MB and was asked to clarify the processes behind the coordination tasks of this role.



6          Multi-User Pilot Jobs - policy status 



Maarten Litmaath updated the MB on the status of the WLCG Technical Forum discussion on MUPJ (Multi-User Pilot Jobs). A complete set of slides is attached to the agenda. Maarten covered the points from slide 13 onwards. Most of the sites/resources are compatible with glexec running in setuid mode. Those not able to support this could be used by the Experiments for running other jobs. The MB agreed that a detailed deployment plan and a realistic time scale are required for deploying glexec with setuid mode at WLCG sites. Maarten was asked to follow this up. Once an initial plan is available the MB will set a date for recommending MUPJs to run with glexec in setuid mode. The next day, during the GDB meeting, Ian Bird sent an email to Tier1 and Tier 0 site managers requesting feedback on when glexec could be deployed at their sites.
