Extending SSL to Google search
21 mai 2010
Posted by Murali Viswanathan, Product Manager
Google understands the potential risks of browsing the web on an unsecured network, particularly when information is sent over the wire unencrypted — as it is for most major websites today. That’s why we offered SSL support for Gmail back when we launched the product in 2004. Most other webmail providers don’t provide this feature even today. We’ve since added SSL support for Calendar, Docs, Sites, and several other products. Additionally, early this year we made SSL the
default setting
for all Gmail users.
As we work to provide more support for SSL across our products, today we’re introducing the ability to search with Google over SSL. We still have some testing to do, but you can try out the new encrypted version of Google search at
https://www.google.com
and read more about it on the

Do Know Evil: web application vulnerabilities
4 mai 2010
Posted by Bruce Leban, Software Engineer
UPDATE July 13: We have changed the name of the codelab application to Gruyere. The codelab is now located at
http://google-gruyere.appspot.com
.
We want Google employees to have a firm understanding of the threats our services face, as well as how to help protect against those threats. We work toward these goals in a variety of ways, including security training for new engineers, technical presentations about security, and other types of documentation. We also use codelabs — interactive programming tutorials that walk participants through specific programming tasks.
One codelab in particular teaches developers about common types of web application vulnerabilities. In the spirit of the thinking that "it takes a hacker to catch a hacker," the codelab also demonstrates how an attacker could exploit such vulnerabilities.
We're releasing this codelab, entitled "Web Application Exploits and Defenses," today in coordination with
Google Code University
and
Google Labs
to help software developers better recognize, fix, and avoid similar flaws in their own applications. The codelab is built around Gruyere, a small yet full-featured microblogging application designed to contain lots of security bugs. The vulnerabilities covered by the lab include cross-site scripting (XSS), cross-site request forgery (XSRF) and cross-site script inclusion (XSSI), as well as client-state manipulation, path traversal and AJAX and configuration vulnerabilities. It also shows how simple bugs can lead to information disclosure, denial-of-service and remote code execution.
The maxim, "given enough eyeballs, all bugs are shallow" is only true if the eyeballs know what to look for. To that end, the security bugs in Gruyere are real bugs — just like those in many other applications. The Gruyere source code is published under a Creative Commons license and is available for use in whitebox hacking exercises or in computer science classes covering security, software engineering or general software development.
To get started, visit

. An instructor's guide for using the codelab is now available on
Google Code University
