Understanding SSO and Microsoft Entra ID for Enhanced Security and Productivity
Single Sign-On (SSO) simplifies access to multiple applications by allowing users to log in once with a single set of credentials. Microsoft’s Entra ID, formerly known as Azure AD, enhances security and productivity by using token-based authentication instead of traditional password methods. This minimizes the risk of insecure password storage, like writing them on sticky notes.
Entra provides different implementations: Federation, ideal for modern SaaS applications using secure protocols like SAML and OIDC, and Password-based SSO for legacy systems. Seamless SSO integrates with on-prem Active Directories, ensuring quick access across platforms by leveraging Kerberos tickets.
Additionally, organizations can automate user provisioning via SCIM (System for Cross-domain Identity Management), eliminating manual processes. Best practices include employing Conditional Access, conducting regular audits, and implementing Multi-Factor Authentication (MFA) to strengthen security measures. By optimizing SSO implementation, businesses can enhance operational efficiency and security.
