Jim is about to go on a river cruise and he's concerned with security when using Wi-Fi on the ship. Leo advises using the Tiny Hardware Firewall. It's a hardware firewall that can protect up to five devices because it uses a built in VPN that protects him. It will slow it down a bit, and the internet is slow on those cruise Wi-Fi hotspots, but it will keep him clean from the last mile.
Tiny Hardware Firewall
Tom wants to make sure his wireless router is secure. Leo says the only thing Tom really needs to do is turn on WPA2 encryption. It's in the router setup, which can usually be accessed at 192.168.1.1. He should turn on WPA2 and give it a password that isn't obvious. Once that's turned on, all the traffic is encrypted.
Ron has the Tiny Hardware Firewall, which he likes. Once he's connected to the VPN inside of it, what does the firewall do, though? Leo says that the firewall is the first level of protection. It acts as a router and is the attack surface, not the computer. A router is a dumb device that doesn't know what the attack is and ignores it, unless there's a security flaw inside the system. Like a router at home, the Tiny Hardware Firewall gives a little extra protection, though.
Chris is looking at the Tiny Hardware Firewall. He thinks it's a great idea, but what VPN client should he use? TOR? Leo says that TOR and VPN are different things. VPN or "virtual private networks" are tunnels bored through the internet, but TOR encrypts it. It is great and Leo uses it when he travels or is using a public Wi-Fi access point. It just fits in his pocket, too. He should be careful when he's joining a public hotspot. He'll get most of the benefits from a VPN, though, if he just surfs to sites using https.
Steve got the Tiny Hardware Firewall and he can't configure it for Wi-Fi. Leo says to give it plenty of time to boot up. It has to boot up twice and it could take up to five minutes before it's ready. So patience is a virtue. He should plug it in, and just wait for 5 minutes before trying to configure it.
Dan wants to know about a VPN. Is it good for security? Leo says absolutely. VPN stands for Virtual Private Network and it's essentially an encrypted tunnel through the Internet where your data cannot be seen by anyone sniffing around. All anyone else would see is gobbelty-gook. It's great for security if you're at an open Wi-Fi network like a coffee shop. VPNs are really popular for work, where you're working from home but want access to your work server.
If you travel frequently, you're probably relying on public Wi-Fi hotspots often. While they are convenient, you should be aware that some of the things you do while connected to that hotspot could be visible to others. Many of the tasks that people do online, including banking, Amazon, Facebook, and most email providers, are already encrypted using https. This means that everything on that connection is secure. You can find out if you're on an encrypted connection by checking the URL in the navigation bar.
