Single Sign-On (SSO) Glossary

Understand the authentication scheme that simplifies user access. Explore our comprehensive glossary of authentication tokens, SAML, OIDC, and preventing password fatigue.

SSO Definitions

Single Sign-On (SSO)

Single Sign-On (SSO) is an authentication scheme that allows a user to log in with a single set of credentials to any of several independent software systems.

TECHNICAL DEEP DIVE

SSO relies on trust relationships between the IdP and Service Providers. Modern SSO is moving toward Phishing-Resistant MFA and Continuous Access Evaluation (CAE).

The ObserveID Advantage

ObserveID enhances SSO security with Behavioral Analytics. We monitor SSO sessions in real-time to detect anomalies and trigger automated responses instantly.

Password Fatigue

Password Fatigue

The phenomenon where users become overwhelmed by remembering multiple complex passwords, often leading to poor security habits like reusing passwords.

SAML Standard

SAML (Security Assertion Markup Language)

An XML-based standard for exchanging authentication and authorization data between parties, specifically between an identity provider and a service provider.

OIDC Protocol

OpenID Connect (OIDC)

An identity layer on top of the OAuth 2.0 protocol that allows clients to verify the identity of the end-user based on the authentication performed by an authorization server.

Frequently Asked Questions

Direct answers to critical questiona about Zero Trust Implementation

How does SSO improve security?

By centralizing authentication, SSO allows organizations to enforce strong MFA and conditional access policies across all applications from a single point.

What is a "Token" in SSO?

A digital object (like a SAML assertion or JWT) sent from the IdP to the application to prove the user has been successfully authenticated.

Is SSO a single point of failure?

Yes, if the IdP is compromised, an attacker could gain access to all connected apps. This is why **ITDR** and behavioral monitoring (like ObserveID) are essential.

What is "Just-in-Time (JIT) Provisioning" in SSO?

A process where an account is automatically created for a user in an application the first time they log in via SSO, using data from the IdP.
