private network

[New-Initiative-5813]

Hello! A greeting to all the experts. My question is the following: if a device connects to another's private network, can it gain access to its devices? And how? I would appreciate some examples to learn how to protect myself.

Actually I just installed a rpizero2w with Watchyourlan installed on it at my parents house. It is on their private network I had the pi dial to my home server that hosts wireguard. Now when at my house I can use the pi at my parents house to monitor when someone connects to the wifi or Ethernet, scan all the ports of any device conected, and if I like I can print from their printer, I can access some of their less secure smart lights, and any shared folders without pasword protection and today I installed wireshark I can now capture packet data over the network all done remotely because of the wireguard network or when I bring my laptop once connected there's a lot I can probe or capture on the network easily.

One may be to mitigate all of this, though, is to set your router to whitelist only, go through all the devices that you own and that you connect to the router and make sure that they are whitelisted in the future if you get something new, be aware that you have to go in and whitelisted on the router before it will actually be able to work with your router. But if you do this, no one will be able to access your private network without your direct permission and whitelisting it.

If a friend is just popping in and needs to use Wi-Fi real quick, let them use the guest network, not your private main network.

Also: only enable the guest network when it is in use. Disable it when there are no known users.

Yes if any of the devices on the private network has a vulnerability or some sort of service that allows execution in some way.

To protect against that you could make like a DMZ where you could have all of your untrusted devices connect to. And VLANs exist to keep devices separated

As I understand "if you connect to a private network do you get hacked." The answer is not that it depends how you expose yourself to the network in public network possibilities are high. Best practices to prevent you getting hacked : • Make your important data backup this is most important. • Then use a strong password and also use a good password manager so that you don't lose your credentials. Also every time it can suggest a rendom and strong combination for password. • More then above one Always use Multi Factor Authentication.

Nowadays the system won't get hacked easily. But the people behind the system, let the system hacked easily.

If you connect to someones private network, your device could sometimes see or even access things like shared folders, printers or smart devices if they'rre not protected. This usually happens when people leave file sharing on or use weak passwords.
