USING WIRELESS TECHNOLOGY SECURELY

How to use wireless securely?

Home Wireless Security

When you use a wireless router or access point to create a home network, you trade wired connectivity for connectivity delivered via a radio signal. Unless you secure this signal, strangers can piggyback on your internet connection or, worse, monitor your online activity or access files on your hard drive. By taking the following actions, you can help secure your wireless home network against these threats.

• Change the default system ID of your wireless access point or router.
• Change the default password for your system.
• Turn off identifier broadcasting.
• Encrypt wireless communications. (WPA-based encryption offers better protection than WEP-based encryption.)
• Use your router’s built-in firewall to restrict access to your network.
• Keep your wireless system patched and up to date.

Public Wireless Security

Accessing a wireless connection from a coffee shop or airport terminal may be convenient and even fun, but you should note that public access points (frequently called hot spots) are often insecure. The following are some steps you should consider taking before connecting to a public access point:

• Use a virtual private network (VPN) if possible.
• Avoid using passwords and providing personal information to web sites.
• Encrypt your files.
• Be aware of your surroundings.
