It enables users to access services from different domains using a single set of credentials, without the need to create separate accounts for each service. Identity Federation is often used in scenarios where different organizations must collaborate or share resources. A key element of this approach is the use of security tokens, which contain user authentication information and are trusted by participating systems. One popular identity federation standard is Security Assertion Markup Language (SAML), which allows secure exchange of authentication information between parties. By using identity federation, organizations can simplify their access management and create a seamless user experience across multiple systems.
CompTIA Security+ Guide: Identity Federation
What is Identity Federation? Identity Federation is a system of trust between various software applications and systems across multiple enterprises. It enables users to use the same username, password, or other personal identity data to access multiple applications.
Why is it important? Importance of Identity Federation lies in its ability to increase productivity by reducing the need for multiple login credentials while enhancing security and privacy. It improves user experience and decreases IT support costs involved in password recoveries.
How does Identity Federation work? Identity Federation works by using Security Assertion Markup Language (SAML). It allows businesses to share secure sign-on information with affiliates and partners securely using SOAP and HTTP.
Exam Tips: Answering Questions on Identity Federation 1. Understand the concepts and benefits of Identity Federation. 2. Know the role of SAML in Identity Federation. 3. Understand how businesses use Identity Federation to share secure sign-on information.
