HTTPS security for web applications

A group of privacy and security experts sent a letter today urging Google to strengthen its leadership role in web application security, and we wanted to offer some of our thoughts on the subject.

We've long advocated forand demonstrated — a focus on strong security in web applications. We run our own business on Google Apps, and we strive to provide a high level of security to our users. We currently let people access a number of our applications — including Gmail, Google Docs, and Google Calendar, among others — via HTTPS, a protocol that establishes a secure connection between your browser and our servers.

Let's take a closer look at how this works in the case of Gmail. We know that tens of millions of Gmail users rely on it to manage their lives every day, and we have offered HTTPS access as an option in Gmail from the day we launched. If you choose to use HTTPS in Gmail, our systems are designed to maintain it throughout the email session — not just at login — so everything you do can be passed through a more secure connection. Last summer we made it even easier by letting Gmail users opt in to always use HTTPS every time they log in (no need to type or bookmark the "https").

Free, always-on HTTPS is pretty unusual in the email business, particularly for a free email service, but we see it as an another way to make the web safer and more useful. It's something we'd like to see all major webmail services provide.

In fact, we're currently looking into whether it would make sense to turn on HTTPS as the default for all Gmail users.
