This is the blog of Ronald Bartels that wanders on and off the subject of problem management (that is how it started), but it is best described by Ray who says this is Daddy's thoughts! Like the best music is from the Eighties and a wee dram helps in solving most inconveniences.
UPnP, Vulnerability As A Feature That Just Won’t Die
UPnP — in a perfect world it would have been the answer to many
connectivity headaches as we add more devices to our home networks. But
in practice it the cause of a lot of headaches when it comes to keeping
those networks secure. It’s likely that many Hackaday readers provide some form of technical
support to relatives or friends. We’ll help sort out Mom’s desktop and
email gripes, and we’ll set up her new router and lock it down as best
we can to minimise the chance of the bad guys causing her problems.
Probably one of the first things we’ll have all done is something that’s
old news in our community; to ensure that a notorious vulnerability
exposed to the outside world is plugged, we disable UPnP on whatever
cable modem or ADSL router her provider supplied.
