When guests are visiting, you simply don’t want them having full access to everything on your network when accessing your Internet.

Many routers also offer the ability to enable guest access to the Wi-Fi network, and it’s generally a good idea to enable a router’s guest access, provided it’s also secured with a password that’s separate from the main Wi-Fi network password, and that guest access also uses a WPA2 password. Eventually, it will be good to migrate to WPA3. WPA3 is also coming which will be even more secure, but it doesn’t have broad device support at the moment. If it’s anything less than WPA2, find out what it would take to switch the security to WPA2. If you’re not sure which form of Wi-Fi security you have, ask your router manufacturer or ISP. My personal recommendation is to use a Wi-Fi password that utilizes WPA2 instead of WPA or WEP. It is important to ensure one’s in-home Wi-Fi network is secure, as not securing one’s in-home Wi-Fi network opens the door to attackers, as well as anyone simply using your home Internet connection for free. This week I wanted to briefly examine three areas relating to Wi-Fi security. If anyone has any additional Mac security topics I haven’t covered, feel free to post a thread, and I’ll be pleased to answer it. This is the final installment of our Mac Security series (although not my final Mac related post as I’ll continue posting each weekend).
