From: Tim Frink on 27 May 2010 18:25 Hi, I have to use an unprotected wireless network (it's not administrated by me). When I understand it correctly, using this WiFi is not safe since all data (such as passwords that I type on my console when I use ssh ...) is transfered unencrypted, i.e., it can be basically read by anyone. Is there a way to use an unprotected WiFi in a safe way by transmitting all data in an encrypted way such that it can't be snooped? Best, Tim

Yes, with a VPN. Comodo offers one or you can roll your own if you have a good place to put a server for the other end. DS

Well, https connections SHOULD be safe. Or at least some people will say so. However, there are many man-in-the-middle tools like sslstrip, midler, etc. that allow an attacker to intercept https. Would you be able to detect a faked certificate? Most people cannot. So - in short - it's difficult - unless you set up a secure VPN to a trusted host, and then tunnel everything through that VPN. Well, I do use ssh on the command line. It will detect a man-in-the-middle attack.

I can understand your concern about "all data", but not ssh. ssh is a "Secure Shell", and data *is* encrypted. |
