sorry, noob question(s), but i wanted to ask if someone could shed some light into some behavior:

i understand that people need the password to enter a network, in most cases at router level.

but will the associated devices like laptops, PCs and phones have the same level of security? - i've only set up a password on my router after all, but the devices themself surely must be sending out periodic beacons like "hey, i'm here! my name is XYZ!" etc.

how are those devices protected against intrusion?

and does it make a difference wether those are actually comnected to a network, or disconnected like an iPhone that's being carried around outdoors?

and lastly: it hasn't happened to me yet, but in theory: what would happen if someone would use the same SSID as i'm using for my router, could my devices accidently send my network's password trying to connect to the imposter's network, since they're thinking it's my home network? or is there something more to it than just the SSID for network identifications?

There are books on the subject. Maybe this will be helpful as intro to the topic.

thanks, seems like a great resource! 🤘
will take a dummy like me some time to grasp the content though 🤓

Simply put, any device on an open network is subject to intrusion. The only network that isn't exposed is a closed network. A closed network doesn't allow access to it externally. The only access is internal. Meaning hard wired and zero access to the internet. I'll add the caveat that even a closed network can become compromised... if someone internally gains access to it.

Of course most users need access to the internet... for email, et al. So the reality is, you are always subject to intrusion... but the degree of said intrusion depends on your usage.

Remember this... anything sent wirelessly is the most exposed because there is no physical connection between the devices. Anything out in the air can be intercepted. Whether someone chooses to expend the time, energy, and resources to do so is another debate.

Your phone has a passcode... every device you own likely has one. The equipment you connect to likely has login credentials as well. So assuming that no one has access to that information, the connection is considered secure. It's when that information is compromised that your security is at risk.

yes, of course... even the best protected governmental network security can be breached, if enough energy is put into that.

my concerns were more if someone with a network scanner who's intercepting wireless calls from other network devices could easily access these without much further ado if he intercepted some IP address, or if a phone searching for it's home network is more prone to be hacked into.
i know this (hopefully) shouldn't be the case, as then we (and even i) would have heard much much more about long time ago.
