Study Notes

Understanding Single Sign-On: Benefits, Criticisms, and Security Issues

Single sign-on (SSO) is an authentication scheme that allows a user to log in with a single ID to multiple software systems without re-entering authentication factors.
True single sign-on allows access to services without re-entering authentication factors, while same-sign on (Directory Server Authentication) requires authentication for each application but with the same credentials.
SSO can be achieved over IP networks using cookies but only if the sites share a common DNS parent domain.
Single sign-off (SLO) is the property whereby a single action of signing out terminates access to multiple software systems.
SSO requires an increased focus on the protection of user credentials and should ideally be combined with strong authentication methods like smart cards and one-time password tokens.
SSO increases the negative impact in case credentials are available to other people and misused.
SSO makes the authentication systems highly critical, and a loss of their availability can result in denial of access to all systems unified under the SSO.
SSO can cause difficulties in countries with active censorship regimes, where the third party website may not be actively censored but is effectively blocked if a user's social login is blocked.
Single sign-on protocols are affected by vulnerabilities like Covert Redirect, which takes advantage of third-party clients susceptible to an XSS or Open Redirect.
SSO can work without revealing identifying information such as email addresses to the relying party, but many credential providers do not allow users to configure what information is passed on.
SSO can be configured for specific environments, such as Kerberos-based Windows, Unix/Linux, smart-card-based, Integrated Windows Authentication, and cross-platform Active Directory integration.
SSO can also use Security Assertion Markup Language (SAML) for exchanging user security information between an SAML identity provider and a SAML service provider, supporting XML encryption and service-provider-initiated web browser single sign-on exchanges.
A newer variation of SSO authentication has been developed using mobile devices as access credentials, which can be used to automatically log users onto multiple systems through the use of authentication methods like OpenID Connect and SAML, in conjunction with an X.509 ITU-T cryptography certificate.
