I have been trying to harden my Debian system by stopping and disabling the 20 or so unnecessary services listening by default. One of them is called "minissdpd". Apparently this provides "discovery" services to plug-and-play devices, whatever that means. Seems kind of crazy to me that something intended to help local peripherals needs to be listening to Chinese hackers on the other side of the world. What does discovery services even mean?
I looked in some vulnerability database, and sure enough minissdpd had a whole slew of vulnerabilities listed. How can they have this enabled in the default distribution? Seriously, its like install Debian, get hacked.
Anyway, my main question is: now that I have disabled this service, is something bad going to happen (like plug something in and it won't work)?
