Now you’re trying to go on a tangent from a tangent. Whether the network guys like it because it screws up something is irrelevant. What is relevant is that it is an example, along with MAC filtering, of security through obscurity that is commonly accepted today.
That you do not understand the concepts of defense in depth, low-hanging fruit, and drive-by really shows you need an education on this subject.
You can keep trying to talk down to me, but you are still failing that the serious security experts all laugh at your assertion that hiding the SID is any layer of security.
So keep on thinking you’re extra secure by hiding behind a hidden SID. It goes well with your belief that the mac is uncrackable.
