Securing a home or office Wi-Fi network

From the start, wireless routers and access networks have their security settings turned off, according to ITWorld, so it is important for people to to enable internet security on these devices before starting to heavily use them.

One development in recent years as a major Wi-Fi security threat is tools that allow people to eavesdrop and steal passwords from wireless networks. The website said this isn't something to be concerned about with home networks, but business Wi-Fi networks should look to guard with enterprise internet security tools. The website also said to be sure to use strong passwords at all times.

"Your WPA and WPA2 passwords are susceptible to brute-force dictionary-based cracking (basically, where hackers guess your password using software tools that repeatedly guess)," the website said. " If your router's password is a word listed in the dictionary--or something close to such a word--it's highly vulnerable to cracking. Use a long passphrase (one of at least 13 characters and as many as 63 characters) with mixed case and random letters, numbers, and other ASCII characters."

PCWorld said the first wave of protection for wireless networks is encryption, with other internet security precautions including firewalls and antivirus software to keep these networks safe.
