sso
See our launch blog post for more information!
Please take the SSO Community Survey to let us know how we're doing, and to help us plan our roadmap!
sso — lovingly known as the S.S. Octopus or octoboi — is the authentication and authorization system BuzzFeed developed to provide a secure, single sign-on experience for access to the many internal web apps used by our employees.
It depends on Google as its authoritative OAuth2 provider, and authenticates users against a specific email domain. Further authorization based on Google Group membership can be required on a per-upstream basis.
The main idea behind sso is a "double OAuth2" flow, where
sso-authis the OAuth2 provider forsso-proxyand Google is the OAuth2 provider forsso-auth.sso is built on top of Bitly’s open source oauth2_proxy
In a nutshell:
- If a user visits an
sso-proxy-protected service (foo.sso.example.com) and does not have a session cookie, they are redirected tosso-auth(sso-auth.example.com).- If the user does not have a session cookie for
sso-auth, they are prompted to log in via the usual Google OAuth2 flow, and then redirected back tosso-proxywhere they will now be logged in (tofoo.sso.example.com) - If the user does have a session cookie for
sso-auth(e.g. they have already logged intobar.sso.example.com), they are transparently redirected back toproxywhere they will be logged in, without needing to go through the Google OAuth2 flow

Moresec Shangfu Cloud Native Protection Platform is a security protection model based on the concept of cloud native. In view of the characteristics of cloud native application life-cycle, it involves in many stages of security protection, including R&D construction, security testing, image control, container deployment, container operation, etc. Shangfu also integrates security with development which means providing feedback of the application security condition through correlating operation asset, and promoting the iteration and upgrade of application. Whereupon, a closed loop of efficient cloud native application security risk is created, covering the whole stages of DevSecOps.
