  1. GRID Security Update David KelseyCLRC/RAL, UKd.p.kelsey@rl.ac.uk D.P.Kelsey, Security Update

  2. DataGrid CA status • National CA already in operation for DataGrid Testbed0 • CERN • Czech Republic • France • Italy • Netherlands • Nordic • Portugal • Spain • UK D.P.Kelsey, Security Update

  3. UK Testbed CA • Old certificates expired 30th April 2001 • Including the CA public key! • Andrew has now re-issued user certificates • There is a new CA public key (with longer life!) • End systems need to be reconfigured for new CA key – see new rpm from Alex D.P.Kelsey, Security Update

  4. Certificates for DataGrid users/hosts • All testbed users get a certificate from their own national CA. • Same for host certificates • Does this cause big problems? • See WP6 web page http://marianne.in2p3.fr • Countries not yet running a CA • Implement one or • Find an existing CA willing to issue certificates • Globus certificates are OK for TB0 but avoid if possible • Will be removed in Testbed 1 (M9) D.P.Kelsey, Security Update

  5. User accounts for DataGrid Testbed0/1 • Certificates from national CA • Requests for “GRID” accounts via WP managers • For definite need only • WP8 predict about 60 users for Testbed1 • WP manager gives list to WP6 • WP6 will arrange for accounts on Testbed sites • This does not scale! • We need to plan beyond Testbed 1 • Longer term – different approach D.P.Kelsey, Security Update

  6. Acceptable use policy? • Do we need an acceptable use policy or other document? • Can show to management to convince them that they should allow an unknown set of people to run programs on computers at a testbed site? • Who are the users? • Why should they use a testbed site? • Do we envisage trusting someone who defines the list of people we will allow to run jobs, access data etc? • Will such lists be signed etc? D.P.Kelsey, Security Update

  7. Configuration of systems • See WP6 web • Part of the standard distribution • To configure complete list of trusted CA’s • To configure the certificate request mechanism • To update CRL’s • Local site is free to accept trusted CA’s or not. • We will check CPS of each CA to define “trust” D.P.Kelsey, Security Update

  8. Authorisation • CAS from Globus • May not be ready/tested for testbed1 • Still uses Grid mapfile • So plan on not using it • Therefore Authorisation via Grid mapfile • gid, uid UNIX security mechanisms • INFN LDAP tool for group membership • Andrew McNab patch for leasing generic accounts • Need input from WP8-10 for group structure • WP6 needs to solve the management/admin issues D.P.Kelsey, Security Update

  9. Future plans • DataGrid ATF now working on implications of security for the architecture (next mtg 29/30 May) • DataGrid WP6 CA mgrs meet on 5th June (CERN) • To discuss CP, CPS etc. • I have proposed a meeting of a new DataGrid Security Task Force (6th June at CERN) • To coordinate WP security deliverables/work • To discuss architectural issues • To plan for future work (+ resource needs) • GridPP has a work group on security (WG E) • Bid for 6.5 FTE (~50% of this for development) D.P.Kelsey, Security Update
