But is it a business service or a support service? I don't think anyone would doubt that security is required, but I'd argue that the purpose is never security that is just a pre-req for going live.
So I'd agree that its a service, just not that its a business service. Security isn't so much the basis for trust as the representation of trust once agreed, i.e. I've decided that I require a secure connection to put in credit card details, therefore you must support HTTPS if you want me to give you those details over the web. Its important in SOA to realise those services which are support and those which are actually business important in themselves. There is a huge history in IT of rating the support (IT) service above the business ones so for instance "security" becomes more important than actually getting the job done.

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]<service-orientated-architecture%40yahoogroups.com>, 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.
