I was with you until this part.
Regardless of the rules or laws, if the government wants it, they will, get it. And your provider will give it to them if needed.

I have work product that could conceivably be accessible without a browser's involvement. For me the added security is well worth the cost and inconvenience.



Having VPN software on your machine is NOT the same as firewall software to protect your local machine. The only way to ensure protection on your local machine is to never connect it to the internet (or use a Mac :-) ).

VPNs privatize and secure the traffic, but do not protect the machine itself. Connect to a public wifi and the VPN will not help you in that regard.

If I'm running a VPN tunnel, the intruder must encrypt and de-encrypt my packets knowing my SSH keys? Doesn't this add a significant barrier to any type of access?

IF your local machine is configured to allow ONLY outside connections that go through the VPN, then while you're connected to the VPN you'd be theoretically safe. If your machine is misconfigured, though, there may be other attack vectors open to a hacker. Running a local firewall is a good idea, because even if properly configured there may be times your machine is connected to a public network but not yet tunneled into a VPN.

So I'm to understand that a VPN is not effective in concealing my activity on public WiFi?

Yes, but a legitimate HTTPS website is already encapsulating your data stream (just to that website) using the same technology.

Yes it will, however the statement was made that he didn't want people sniffing around his personal PC because of sensitive work documents. A VPN does not provide that level of protection.

Think of a VPN like an armored car - it protects your data in transit. But it doesn't do anything about protecting the bank vault.

Are you saying that if I'm already using HTTPS connections via my browser, that a VPN tunnel offers no additional security that would prevent an outside hacker to access other resources in my computer?

In short - yes.

I agree with some of what Joshjack says, but consider this. When you are at an HTTPS web site you are safe, BUT, you could have been hijacked before you arrive at that site if you are on a public network. The VPN is a tunnel between you and another computer. The protection doesn't extend beyond that.

For example, if you have a VPN connection to your work or bank and then you have access to go through that connection by browser to a web site. The VPN can't protect you because you have left the protected tunnel. (Most VPN connections won't allow you to go out to the Internet after you have established the tunnel, so it's most likely not an issue.)

Another example would be if you are on a public WiFi connection, check your email, do some browsing, etc. and then go to an HTTPS connection, you may already be compromised before arriving at the secure site.

So it's best to avoid any public WiFi if at all possible. I do use it but only like stores I happen to be in, like Home Depot, Lowes, etc. If you're out somewhere and see a hotspot like "FreeWifi" or "PublicWifi", something that looks suspicious, it's probably someone that's looking to get into your computer.

If you don't have the option to use your cell phone as a hot spot, I recommend the Verizon Jet Pack ($50 for the hardware) with "pay as you go" access. It's a secure (albeit somewhat expensive) connection. I use one when I'm away from home and I don't have to worry so much. :D

Thanks Rich for this overview -- very helpful!

For everyone's information, here is a recent Verizon thread:
