Is MFA Enough? Understanding Authentication and Session Security
A Practical IAM Architecture Perspective Multi-Factor Authentication (MFA) has become an important component of modern Identity and Access Management (IAM). By requiring additional evidence during authentication, MFA can significantly strengthen protection against compromised passwords. However, enabling MFA does not eliminate every identity-related security risk. Modern IAM architecture must address more than the initial login. It must also consider session management, token protection, access decisions, and the detection of suspicious activity after authentication. For IAM architects, cybersecurity professionals, and security engineers, understanding these relationships is essential to designing resilient identity systems. 1. What Does MFA Protect Against? MFA requires users to provide multiple factors of authentication, typically drawn from different categories: Something the user knows, such as a password. Something the user possesses, such as an authenticator device. Somethi...
