May 2012
OAuth-based single sign-on in Real-world Implementations

Speaker: San-Tsai Sung

Date & Time: Monday, May 28th, 2012 @ 5:30pm

Millions of web users today employ their Facebook accounts to sign into more than one million relying party (RP) websites. This web-based single sign-on (SSO) scheme is enabled by OAuth 2.0, a web resource authorization protocol that has been adopted by major service providers. The OAuth 2.0 protocol has proven secure by several formal methods, but whether it is indeed secure in practice remains an open question. We examine the implementations of three major OAuth identity providers (IdP) (Facebook, Microsoft, and Google) and 96 popular RP websites that support the use of Facebook accounts for login. Our results uncover several critical vulnerabilities that allow an attacker to gain unauthorized access to the victim user's profile and social graph, and impersonate the victim on the RP website. Closer examination reveals that these vulnerabilities are caused by a set of design decisions that trade security for implementation simplicity. To improve the security of OAuth 2.0 SSO systems in real-world settings, we suggest simple and practical improvements to the design and implementation of IdPs and RPs that can be adopted gradually by individual sites.

Outsourcing Identity: Understanding Privacy and Security in Identity Services

Speaker: Yvan Boily, Web Security Engineer, Mozilla Corporation

Date & Time: Monday, January 23rd, 2012 @ 5:30pm

Social Media has taken over the online world; what Microsoft attempted with Passport has been made reality by Facebook, Twitter, Google, and other service providers. In addition to the proprietary identity services these platforms offer, several support protocols such as OpenID, This will be a one hour presentation that will contrast the security and privacy features available in major online identity protocols, and contrast these with Mozilla's BrowserID protocol.
