Google is now encrypting all Gmail traffic from its servers to its users in a bid to foil sniffers who sit in cafes, eavesdropping in on traffic passing by, the company announced Wednesday.
The change comes just a day after the company announced it might pull its offices from China after discovering concerted attempts to break into Gmail accounts of human rights activists. The switch to always-on HTTPS adds more security, but does not help prevent the kind of attacks Google announced Tuesday.
All Gmail users will now default to using HTTPS, the secure, encrypted method for communicating with a remote server, for their entire e-mail sessions, not just for log-in. Session-long HTTPS has been an official option for Gmail users since 2008 (and unofficial for much longer), but Google says it hesitated turning it on for all since the encryption does slow down the service.
“Over the last few months, we’ve been researching the security/latency tradeoff and decided that turning https on for everyone was the right thing to do,” Gmail Engineering Director Sam Schillace wrote in the Gmail blog.
This option often wasn’t necessary when people used fixed and trusted connections, such as their home or office DSL or cable lines. But as Wi-Fi connections, especially public ones, became more popular, hackers began using simple sniffing software to snoop on people’s online activities with the goal of stealing passwords.
Still, the switch doesn’t encrypt e-mail — it simply encrypts the communications in transit between Google’s servers and a user’s computer — the same as when you use your bank’s website. E-mails sent to other people are transmitted in the clear as they have always been. True encrypted e-mail can only be read by the sender and receiver, regardless of how they move across the internet.
For those whose schools or workplaces that routinely monitor employee or student internet usage, the change also shields their e-mails from the IT department.
A coalition of privacy and security experts called on Google publicly to make the change last June, saying that Google was putting millions of people at risk by not using encryption as the default for their so-called cloud computing services.
Users who find the service slows them down or determine that it’s overkill for their needs can turn the HTTPS off in their account settings.
Rival free e-mail from Yahoo and Microsoft do not use HTTPS throughout their sessions, nor do social networking sites or other so-called cloud-computing services.
Instead, most of those services use the secure “HTTPS” protocol only for logging in, and fall back to unencrypted browsing thereafter.Failing to use HTTPS full time increases one’s vulnerability to a host of nasty hack attacks when using an open or badly secured network, particularly a public Wi-Fi spot.

So I've had 1 post in the last year. That really pathetic. After looking at the last year or two in happenings and other things, I will post some hints and tips on personal technology and security. There's been a few friends that have had their Yahoo, Facebook, GMail, and other online accounts hacked. The worst thing is that the hacker is exploiting the relationship that person has with their friends/followers/contacts to extort money or other things. Lets see how this goes.
