WiFi Network Security

[Charan]

hello guys, I have a question.. how to protect a wifi network from being hacked. I have WPA2 enabled with a strong key but I havent set MAC filtering yet and will enable it soon..
Are these two enough ? I do have filesharing enabled for some folders but not for personal data. I really need file sharing most of the time. I got this question on my mind cause two additional wifi network from my neighbourhood poped up in my wifi manager .. one was protected and the other unprotected.. I wont hack into those two network .. are we safe in this wireless world?

currently wpa2 is the strongest... mac filtering is one step ahead.. as long as you don't reveal your mac address you are safe. rest assured
