Cloud security mechanisms - identity and access management (iam) → - propagating the authentication and authorization information i or a cloud service consumer across multiple cloud services can be a challenge, especially if multiple cloud services or cloud-based ii resources need to be invoked as part of the same overall runtime activity.
- the single sign-on mechanism enables one cloud service consumer to be authenticated by a security broker, which establishes a security context that is persisted while the cloud service consumer accesses other cloud services or cloud-based it resources. otherwise, the service consumer would need to re- authenticate itself with every subsequent request.
- the single sign-on mechanism is commonly used by public cloud providers to establish a security broker that supports single sign-on for multiple it resources within the same cloud.
- the single sign-on mechanism relies on the identity and access management mechanism to provide an identity store that is used by the security broker.
- the single sign-on mechanism does not directly counter any of the previously described threats.
