Securing a Web Service

[M Jay]

Hi,

I am part of a project that aims to SOA enable my organization. This is being achieved through Web Services and the use of an ESB. We now have a requirement to expose one of our Web Services onto the internet to be consumed by a number of mobile devices - this is not a public service, but a third party organization will invoke our service from a number of mobile devices. How can we make sure that our web service is secure? Would using SSL with Client authentication be sufficient? I have been reading a few articles around XML Digital Signatures and XML Encryption/SAML ...etc but this all seems to be message-level security and I don't feel that those technologies are relevant. Our main requirements are to authenticate the client and ensure that messages exchanged are secured, in addition to securing the service against DoS attacks.

Thanks for your help in advance
