3. Virtual Organization
Definition
• Grid Virtual Organization (VO)
– Set of resources (computers, storage systems)
– Distributed among participating organizations
– Available for use by a group of users
– Is defined by the grouping of resources plus the
grouping of individuals, brought together for a
common purpose under mutually acceptable
governing rules.

5. Creating a VO
• Hosts and users must obtain certificates
• Users are then granted access to hosts (by
the owners of the hosts).
• The set of users coupled with the set of hosts
they are allowed onto is what “defines” the

7. CEOS Grid - CAs
• CEOS Grid Users will not all have the same
CA
• We want to limit the number of CAs to the
smallest possible set.
– Makes management easier
– Makes policy decisions easier
• European users already have a high-quality
operational CA
• US Users are encouraged to obtain
certificates from NASA IPG

8. CEOS Certificates from
NASA IPG
• NASA Information Power Grid (IPG) already runs a
high-quality CA that is accepted by most VOs.
• NASA IPG is providing CA resources for the CEOS
Grid.
• Current status
– Certificate request software has been delivered & tested.
– Operating well at 2 test sites (II, SGT) and at GMU.
– Others are encouraged to try it out.
• Availability

13. General Firewall Issues
• Using the Grid means that you have to make new
services accessible to the internet
– System administrators and security people will be
uncomfortable with this
– Some sites have different policies, some are set up to allow
experimentation outside the firewall
• What you can do
1. Familiarity - install & test on a machine outside the firewall,
learn about the Grid
2. Provide information about security issues to people who
need it
3. Develop a relationship with the people you depend on for
access

14. Firewall
• Tech Team has put together a firewall document
http://grid-tech.ceos.org/gridwiki/FirewallBestCommonPractices
• Contents
– Introductory material
• CEOS Grid overview; Quick primer on Grids; Globus port
numbers
– Site specific sections
• Meant to be filled in by each site with anything you learned that
might help someone else
– Product specific info
• Currently only one - Cisco instructions
– Miscellaneous
• Open Questions; References; To Do

20. CEOS Grid Toolkit Catalog
• We need to put some thought into how we
want to describe the components.
• Possible metadata elements (thanks to Stu
Doescher):
–short name –Contact points
–long name •supported and by who
–summary description •used by
–pointer to additional discussion –Technical parts
•Language
–latest version and date
•how to install
–maturity - new, obsolete
•problems
–other parts needed
–recommendations
