I don't have an engineering degree, but rather a CS degree. Did I learn proper design and protocol for making secure software? I support requiring some sort of registration/testing/regulation of Professional (software) engineering, just like my mechanical engineering friends
Some schools have their CS program in the engineering department and have requirements which follow from that dependency. So whether you have an engineering degree depends on the school?
Otherwise I agree, there should be a standard for professional software engineering. There are efforts underway already in that direction.
