@Missy,I think you worry too much, hehe
. While it's true that hacking is a concern and your fears could be true (the videos that you see in youtube proves that) - in a home wifi hacking should much less be a concern. Public wifis are more dangerous.
I'm speaking as a techie myself here.
Nope other people in your network won't
be able to access your email, FB, chat etc and they won't ever see what is in your history folder. Yung mga emails these days are pretty much secure - the sites start with "https". You can configure your FB to use secured connection rin. There's no easy way to decrypt any secure website even with the use of sniffing tools
. Most chats are transmitted using secured connections too. Also even with a sniffing tool it is not possible to see/easy to figure out if you are transmitting anything "private" via chat or webcam.
Remove those "shared" folders sa computer network so others won't see what's inside them.
Double check your computer for any hardware and software keyloggers. Since you are using mac, baka wala rin lang ang mga yan sa mismong computer mo.
Pag napilitan ang password ng wifi, then there's no way for him to be able to get into the network and even access their internet connection unless he has hacked his way into yours. By the way, did you put password din on the admin page and change the IP address ng mismong router ninyo?
Consult your router's manual for this. Pwedeng nakuha ni neighbor ang password that way (and this simple hack involve any use of tools). Also, change the password often and don't use easy to guess passwords (baka nahulaan lang? this is highly likely). It should be a mix of uppercase and lowercase letters and with numbers.

While it's true that there are those tools for sniffing tools, halos bihira ang mga hackers than you ever think. Hacking is a time-wasting activity. Not all techies are into hacking and would even know how to hack. Masasayang lang ang oras nila figuring out which websites you have gone, what apps you have opened, etc. I strongly doubt your neighbor could even have ALL the time in the world to do that.
So if your neighbor found out you have been visiting pron sites, so what? It won't make that guy next door a rich man. He's might have just realized that he is wasting time. Despite having a sniffing tool, the hackers don't easily see things the WYSIWYG or "what you see is what you get" way. It's a series of cryptic numbers, symbols and letters that takes time to decode - which is why it is such a time-waster!
Chances are, mahina ang signal ng wifi mo, so the incident of getting hacked by those who roam in neighborhoods and by those who live the next door is very very smal
l. I drive a car myself, at karamihan, mahina ang signal ng wifi sa road to even "leech" into them. Sayang lang ang gasolina just finding a strong wifi in neighborhoods. My own strong wifi at home could not even reach the gate of our place!
I also live in an apartment with several neighbors next door and I could not see any other computers logged in my router - been using a router for more than a year now.
The ones who own the strongest wifi signals are business establishments, because they could afford to buy wifi repeaters, industry-type wifi routers and bigger wifi antennas to boost their signal across the road. This is why I prefer to park beside business establishments instead to "leech", because of their strong and fast internet signals.
Lastly, use a recent-model router - the one that you can configure for WPA2-PSK security type. When you change this, you have to upgrade all your devices in the network to support this one. If you are still using WEP router, it just takes seconds for the hacker to get in using brute force, so I strongly suggest that you upgrade to a better router. Hacking a WPA2-PSK router is difficult - still possible but less likey and is very very difficult.
Else, if you are still uncomfortable with everything WIFI, then go for wired connections na lang - buy a wired router instead and use Ethernet cables to connect. Sigurado na yan, sis, wala nang hacking na mangyayari, unless the hacking incident comes from your internet connection online (and this is another story to tell).
