  • I think what the commenter is saying is if you have something running on a server on an external IP address for like a website that needs to be public, the additional risk of opening up more ports to slow down Internet scanners is not beneficial to you and not worth the risk.

    If you’re deploying an raspberry pi and opening it up to the Internet, and don’t care if it crashes due to overload, thats a bit of effort and cost you incure to keep it running to be a nuisance.for Internet scanners. If you don’t have anything which needs to be publicly accessible to the Internet, the best thing you can do is not open any ports and expend no effort, so that the firewall/ NAT gateway operates in stealth mode which is does inflict some processing and time on the Internet scanner to run waiting for responses to timeout.





  • I used to work with a guy that worked at Apple Computers in the 80s/90s in Japan I think when they were getting into the market there. He described an anecdote from that era where Apple had a high volume of returns and were trying to figure out why, since the hardware was functioning when it was received. Turns out most of the returns were because the coiled cable for the keyboard would get messed up and not coil properly, which was inconvenient but acceptable in the western markets, whereas in Japan that was unacceptable for the average consumer.
