Asegurar su red wireless

If you don't secure your network, you provide an entrance point to everything on your network, including personal information.

Tip 1: Don't let strangers use your network: Turn on WEP (wired equivalency privacy) or WPA (Wi-Fi protected access) on all of your devices, including your router, your media center, and your Xbox system. For more information, see Set up a security key for a wireless network.

Tip 2: Move your wireless router: Place the wireless access point away from windows and near the center of your house to decrease the signal strength outside of the intended coverage area.

Tip: 3: Use a firewall: Use a firewall on each computer on the network and keep all of them current (Windows Vista and Windows XP SP2 and later include a built-in firewall that is turned on for you). For more information, see How to choose a firewall. You should also make sure your router is configured to allow only the minimum amount of required inbound traffic.

Tip 4: Update your software: Visit Microsoft Update and use automatic updating to keep Windows and related security tools current.

Tip 5: Use antivirus software: You need antivirus technology to help prevent viruses, and you need to keep it regularly updated. To scan your computer for viruses right now, use the Windows Live safety scanner.

Tip 6: Use antispyware software: Windows Defender, which is free from Microsoft, can help protect your computer from spyware and other potentially unwanted software. Windows Defender comes with Windows Vista. If you use Windows XP SP2 or later, you can download Windows Defender for no charge.

Tip 7: Limit the amount of private information on your computer: Do not store passwords, social security numbers, or credit card numbers on your computer.
