While securing your wifi router will help keep hackers from getting access to your network, what about the potential for harm from people who already have legitimate access to your network? Having a firewall will certainly help, but it may not be enough.
One of the best ways to limit your exposure to intra-network harms is by prohibiting file sharing access from foreign machines. This is especially important if you are on a large scale or open wifi network, such as at a college library or in an office building, where you do not know who could be potentially browsing through your PC.
Suggestions:
- Use the AllPeers plugin for Firefox web browser to enable secure sharing over the internet.
- Use secure sharing via one of the VoIP (Skype) or VoIM (Google Talk, Yahoo Messenger, Windows Live Messenger) clients as an alternative option.
