Best Practices for Identity Federation | CompTIA Cloud+ Exam

A.

The correct answer is A. SAML (Security Assertion Markup Language).

Identity federation is a process in which an organization's identity management system (IDM) is connected to a cloud-based application or service to provide a single sign-on (SSO) experience for users. SSO enables users to access multiple applications and services with a single set of login credentials.

SAML is a protocol that enables identity federation between an organization's IDM system and a cloud-based application or service. It provides a framework for exchanging authentication and authorization data between parties. SAML is an XML-based protocol that uses security tokens to enable SSO.

NTLM (Windows NT LAN Manager) is a legacy authentication protocol developed by Microsoft. It is used to authenticate users in a Windows-based network environment. However, NTLM does not support identity federation, and it is not commonly used in cloud environments.

MFA (Multi-factor authentication) is a security mechanism that requires users to provide two or more types of authentication factors to access a system or application. MFA enhances security by adding an extra layer of authentication beyond the traditional username and password. However, MFA is not directly related to identity federation.

PKI (Public Key Infrastructure) is a system that uses digital certificates and public-private key pairs to enable secure communication over the internet. PKI is commonly used to secure web transactions, email, and other online communication. However, PKI is not directly related to identity federation.

In summary, SAML is the best option for enabling identity federation in cloud environments. It provides a framework for exchanging authentication and authorization data between parties, and it is widely supported by SaaS providers.
