What does “security” mean in the context of Wi-Fi?
In the context of Wi-Fi technology, security means two things. First, controlling who can connect to and configure your network and equipment. Second, it means securing the data travelling wirelessly across your Wi-Fi network from unauthorized view.
Wi-Fi security is just one aspect of security for networks. A protected Wi-Fi network is a great start, but you should also consider measures to protect your computer (virus software, firewall, etc.) and your communications across the Internet (virtual private network (VPN), etc.)
