Why Web services should care about grid security Taavi Hupponen, CSC
Background Web services enable efficient access to services that have traditionally been accesses through web pages This puts more load on service providers Grid middleware is being implemented with Web Services
Reason 1: Who is using my resources? With increased resource usage, the service providers will get interested on who is using their resources There will be need for identification, authentication, authorization and accounting Not necessarily at individual level but at least in some level This is stuff that is hard to get right Grids have been dealing with these issues for quite a while
Reason 2: Grids can provide resources for your services There is need for more resources, grids can provide them If you are using grids as backend for your services, you end up identifying the users or yourself with the grid security mechanisms Maybe you could avoid having two different mechanisms, by using grid stuff also for the Web service
Reason 3: Using grids through Web Services interface Grid middleware is being implemented as Web Services For example Globus Toolkit 4 This may enable use of grid features and services through Web Services interfaces Web Services interface or not, grid security mechanisms will be there
Reason 4: Certificates Grid users already have certificates Imagine having different username and password for all those Web Services seen in Taverna Web services are used by programs It is easier for programs to use certificates than usernames and passwords
Reason 5: You want to concentrate on functionality!
