Well, to my experience, security is doing A LOT for the business (http://java.sys-con.com/read/131811.htm, http://java.sys-con.com/read/163285.htm). Besides it is a foundation for the business trust, I had several cases where business simply could not operate w/o security. Here is an example: financial report distributed among investment experts contains some information which is assumed to be seen by the bankers of certain level of responsibilities and in certain locations only. Are you going to create multiple reports or filter data based on user access rights / entitlement? Though security topic does not belong to the forum, I believe it is a legitimate SOA service and I still staying on the position about SOA services I described earlier. - Michael Jim Thomas <[EMAIL PROTECTED]> wrote: I still disagree although I admit it's a bit of a nit. The security service has nothing to do with business at all. The dependency flows in the other direction. Supposing the security service is used in a purely scientific system then "business" seems a misnomer. --- In [email protected], Michael Poulin <[EMAIL PROTECTED]> wrote: > > I think that creation of 'generic' (infrastructure - in my understanding) services does not contradict 'business-centric' definition because, e.g., security service is not about generic or abstract safety but about protecting business interests (scientific results, in particular) and building business trust; transport services serve the same purpose - allowing business to operate. Not all services have to implement business services directly but those, that do not implement them, exist because of the needs of the business services, not because they are coooool. All this is about money paid by a business for its benefits.
