Hi, I looking for some extra money, and i was thinking in the weekends i could secure peoples networks. What help I need from you lot is what ways I can secure peoples networks, apart from the stuff next. Broadband firewall setup, wireless password length and encryption, disable WINS(if not need), update/patch OS, maybe make some tools that will mointor network for stuff like mitm/or install from internet.

Any other ideas people
Thanks
