Scanning for open ports on other peoples networks? How is that different from casing a house for entrances? It’s behavior only two types of people would have: criminals and security professionals.


> Scanning for open ports on other peoples networks? How is that different from casing a house for entrances?

It's more like looking through other people's windows as you walk by the street. May be creepy if you always stare at the same window, but formally there's nothing wrong with that. If you do not want people to see through your public-facing windows in your home, it's your responsibility to install blinds or shades.


More like ringing the door bell and running of to the next house?


If you walk around town looking in every window, you’re probably not gonna have a good time when you get detained or shot. Let’s not pretend like there are legitimate use cases for scanning ports of networks you don’t control.

Dude, what kind of town do you live in? It sounds scary!

Here in Europe many towns have narrow streets with houses directly by the street (with no front yard). It is essentially impossible to not look through the windows of people unless you make a robotic effort to avoid it.


Hint...it's probably NOT Europe :)


TIL there are hackers living in high-crime areas. Seems like a good idea to move to a neighborhood where you won’t get shot for having your eyes up, which is almost all of my city.


The US. And a big city where such behavior will end badly for you. The general rule is not to fuck with other people.


A few years ago, in Paris, my commuting by train got perfectly synchronized with the alarm clock of an old gentleman who lived next to my workplace. Every day, he opened his window exactly as I was passing in front of it. After a few weeks, we got to know each other in that strange way that people "know" each other but have never talked. After a few months, we were saying "bonjour" to each other, and sharing a smile. I would be honestly surprised if the man suddenly decided to shot me! Would that be a common thing to do in the U.S.A. ?


Don’t be daft. You weren’t peeking in his window or at his back door, and you didn’t do that to a thousand houses. If you think this is acceptable, I dare you to go around the nearest city to you and start checking all the windows and doors on every house you can for a day.


>The general rule is not to fuck with other people.

I do that..even in a big city. It's cool when you do it to yourself, but makes much more fun with a another person, you should try it out someday.


>Let’s not pretend like there are legitimate use cases for scanning ports of networks you don’t control.

You can ask Ebay about that.


If you don't want anyone connecting to you network, don't connect it to the internet. If you only want certain people to access your network, whitelist their IPs.

If you don't want people to look at you, don't go out in public.


Or just curious people who interact with the internet directly for fun. Not everyone is confined to a web browser and facebook. No one is hurt, no one is defrauded, and no one's privacy is impacted by using the internet as it is meant to be used.


> How is that different from casing a house for entrances?

If you don't see a difference then I hope we don't share neighborhood.

> It’s behavior only two types of people would have: criminals and security professionals.

consider also curious people seeking knowledge; the Internet is a massive space and an interesting phenomenon in itself, scanning is one of many ways to learn about it.


He did not suggest casing a house is OK.


>How is that different from casing a house for entrances?

Your House is not a Server, compare it to a Butler, i yell into your house and if a Butler answers i ask him whats on the table.


Security professionals are born that way?


Hehe, and the experience comes from books...no need to do it with your own hands. Same with pilots just read a book and that's it...maybe some Microsoft flight-simulator hours too.


I hope that's sarcasm. Hard to tell


>Hard to tell

Yeah rlly hard ;)


Yup it is ;)
