i was curious if its ok to ask things that how to do something.For example a guide somewhere or how i could do something or how things work and whats the logic on them. for example i heard something that its possible your router to get hacked even if u have the access with key and macaddress on and am curious for some security things for other programs too but i am not sure if its allowed to talk about these things here
