James has heard about the Dark Web. What is it? Leo says the "Dark Web" is part of the internet that isn't available to search engines. It's websites that can't be picked up. This includes Tor websites that don't allow for identity on the net. Originally it was used by universities to protect academic and research information. Now it's become a bit more nefarious with use for criminal activities via Tor. How can the Dark Web be accessed? By knowing the web address of the location that is hidden.
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.
Andrew is always traveling and he's thinking about using a VPN since he's always on public Wi-Fi hotspots. Leo says that's a very good idea. Most places he'll visit online are encrypted, but Leo has read lately that it's becoming really easy to get into computers over public Wi-Fi. Leo says a VPN will work, but it slows him down.
Juan is looking to use Tor for encrypted security. Leo says that Tor was invented by the US Navy and it works by making your traffic obscure. Tor is used for anonymity, and it's a bit difficult to set up, but using a Tor browser makes it a lot easier. If Juan is concerned about privacy online, Tor is a good option to look into.
