Mark hears that Public Wifi may not be safe. Is that true? Leo says yes and no. When we're on a public network, people can see our connection. We can see other people's computers in our browser. We may not be able to see everything, but a hacker can use what's called a "WiFi pineapple." So there is a potential risk. But with a secure connection via HTTPS, they can't really see anything. That's why Google is pushing hard for every website to be https. That's why it's Leo's opinion that we're mostly safe. When in doubt, just use a virtual private network while on a public wifi.
Gordon is in the hospital, and wants to know if their public wifi is safe or should he use a VPN? Leo says that if it's using a wide-open network, then anyone can log in. It's a shared, public network. There are some risks, but your banking is safe because it's encrypted. The one thing to worry about is a "man in the middle" attack. Hospitals with public wifis could give the hospital the ability to watch what you do. That's when a VPN can come in handy. It will encrypt all traffic, by burrowing an encrypted tunnel to the internet.
Robert has a Samsung Galaxy Note8 and he wants to know about Bixby. Leo says that Bixby is bascially like Siri or Hey Google, but Bixby can do a few other things. They're called Bixby routines, and it'll do things that users set up in advance. Users can even edit video with Bixby.
Louis travels with his iPad and would like to know if there's a VPN for iOS. Leo says you have a few ways to go. Leo says that 18.104.22.168 is an app that isn't strictly a VPN, but it changes the DNS to give privacy from an ISP. The benefit is that it doesn't slow users down. But if customers want something to completely protect them at a public space, Leo says to purchase ones like ExpressVPN, or NordVPN. Both are offshore and don't log user activity. There's also Tiny Hardware Firewall as another option.
David wants to know if he should back up his mobile device to Verizon Cloud. Leo says to not do it. They'll give a little bit for free, but they really want to charge extra for it. And he can back up to Google Drive for free. What about Verizon's VPN, is that worth $3.99 a month? Leo says that most paid VPNs are that much... but the question is, do we trust Verizon? Verizon is using McAfee's VPN services, and have in writing that they aren't logging user activity. So that's probably fine, especially at that price.
Mike is down in Cabo a lot and he streams using high-speed DSL. He uses a VPN but lately, the ISP has been shutting him down. Leo says that it sounds like the internet companies are getting wise to that. Sometimes users can switch VPNs and get back up and running. Another option is to set up a VPN server at his server in the US, then surf to that with Remote PC.
Tom uses DashLane for his password vault, and wants to know if their new VPN service slows him down. Leo says it can. He's essentially running a computer remotely, and it works with an encrypted tunnel. So, it can cause some latency as it works its way in and out of the tunnel. Not all VPNs are alike either. Some are faster than others, so he should check with DashLane to see how many servers they run. He also wants to be sure they don't log his use. Tom also doesn't like that he doesn't have the option to opt-out after they raised his monthly fee.
Jeff wants to use Mint online, but he's concerned about putting his data online. Leo says that Mint is very secure and he uses it for his business at Tech Guy Labs. Does Mint work with 2 Factor Authentication? Leo says yes, and it does support password vaults like LastPass. But all the security in the world doesn't protect him from a data breach.
John is going to college soon and he's concerned about Wi-Fi security. Should he have a VPN? Leo says he can. He can find out how open the network is by going into iTunes to see if he can see someone else's iTunes library. If he can, then it's insecure. If he can't, then it's locked down.
Travel Tip - When traveling overseas, always pay in local currency. If they ask if you'd like to pay in US dollars, you'll likely get charged a conversion fee with your credit card. Also. Let your bank know that you're traveling overseas. Also, pay using a credit card. Your debit card is no protected if the card gets stolen or hacked.
Another tip - use a VPN while traveling with your internet access. You'll actually save money by pretending you're in a different country and you're booking flights. Leo uses a travel router, which protects him overseas.
