Standard web services v Secure web services

Question

I ask this question in anticipation as part of a project. I have experience of developing and consuming web services in the past and am au fait with those. However I have been told that as part of this next project I will need to use "secure" web services. Can you provide some insight into what additional development tasks there will be to implement these as opposed to standard dare i say it insecure web services?

Cheers

Unless you have a complex multi-hop scenario, then SSL is vastly more practical and interoperable than anything based on WS-Security or related specification
