It’s amazing what a difference a little bit of time can make: Two years after kicking off what looked to be a long-shot campaign to push back on the practice of shutting down server-dependent videogames once they’re no longer profitable, Stop Killing Games founder Ross Scott and organizer Moritz Katzner appeared in front of the European Parliament to present their case—and it seemed to go very well.

People like to think in black and white, but you’re definitely right. Having your SSH server on port 36271 will likely stop a ton of drive by attacks because they simply won’t check it. Having it only listen on IP6 would stop almost all of them because you can’t trawl the IP6 space efficiently. These are “obscurity”, but they have real benefits. The idea that “obscurity” doesn’t help is just a meme that people love to quote because it’s a great single sentence with some nice rhyming “security by obscurity”. I assume the reason it became a meme is because tons of products fully relied on obscurity; I still see it all the time. As you said, it’s all layers.
Yep! I don’t know a single engineer who would say that security by obscurity is never useful. Everyone knows, as you said, to put SSH on a random port. It’s the first step you do to secure a server.
