<p>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?</p>

<p>Cheers</p>
