Tyler does a lot of social media through YouTube and Twitch and he's been hit by a DDoS attack. Leo says that those attacks are easy and are usually done by a troll who has an axe to grind. But they can't go after Twitch, so he's attacking his personal IP address. Leo says to call the ISP and request a new address. Running through a VPN will prevent it since it's an encrypted tunnel and they can't see the IP.
Bruce wants to know if his friend's website should be using a VPN for secure web access. Leo says that he can, but the first thing web sites should be doing is running a secure site with https. Amazon uses an extended SSL certificate which has a green bar so that it's even more secure for eCommerce. Using a VPN like HotSpot VPN or Tunnel Bear can give him a secure and ecrypted tunnel to a server.
David wants to know about Tunnel Bear. Leo says that Tunnel Bear is a virtual private network or VPN, which essentially burrows a digital secure tunnel in the internet. Is it secure enough to bank with or should he just trust "https"? Leo says both are very similar. The difference is that https activity cannot be seen by anyone, but they can see that he's been online. It can also be probed, whereas VPNs are tunnels that encrypt all of the traffic. no one could see anything. It's more security, but similar security. It's up to David.
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.
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.
Bruce does a lot of writing and traveling, and he's wondering if a Chromebook is a good option or should he bite the bullet and get a Surface Pro. Leo says that if you don't really need all that functionality, a Surface may be overkill. The Chromebook, by contrast is ideal for what Bruce does. It's secure, You backup your data to the cloud, and it's ideal for VPNs, which is what Bruce needs.
Bryan wants to know how secure Google Fi is. Leo says that there isn't any data beyond it, but there's word that all traffic is routed through Google's VPN. So if he trusts Google, then there's little to be worried about. If he doesn't, he should just remember that he still has to trust the carrier.
Rob wants to know if he should use a VPN when he pairs his smartphone to his laptop. Leo says no. Modern digital cell phones are encrypted and no one has yet hacked their way into that signal. It wasn't like the analog days when you could listen in to cell phone calls with the right software. That can't happen with digitally encrypted mobile phones.
Doug does a lot of traveling on the road and he uses a open Wi-Fi hotspots a lot. He's worried about the security of using those hotspots, though. Leo says that using a Virtual Private Network (VPN) is a good solution, as it burrows a secure tunnel through the hotspot so that all of his data is encrypted. He'd be totally safe and secure. The downside though it that using a VPN will slow him down a lot, and they are a challenge for some to set up. And the reality is, more and more of what he'll be doing online is encrypted anyway.
