One of my friends has a child who used to bring a blanket with her wherever she went. It didn't matter that it was a hundred degrees outside; she carried it more for comfort than to keep herself warm and safe. Not that it protected her in reality, but it provided the illusion of safety, which is often as important.
When Web services first burst onto the scene, which in my mind was the beginning of the SOA movement, one of the biggest challenges faced by early implementers was the perceived lack of security. Fear and uncertainty abounded, and it was years before the majority of IT organizations became comfortable with the level of security that could be provided.
