Bottom line: The BSI has identified security deficiencies in Windows Hello for Business that require a critical reassessment of this authentication solution for enterprise deployments.
The Federal Office for Information Security (BSI) has conducted a security analysis of Windows Hello for Business and identified vulnerabilities in Microsoft’s authentication solution for enterprise deployments.
Windows Hello for Business is Microsoft’s solution for passwordless authentication in enterprise environments. The system uses biometric data or PIN-based authentication as a replacement for traditional passwords and is intended to combine security and user-friendliness.
However, the BSI investigation reveals weaknesses in this security concept. The exact details of the identified vulnerabilities are documented in the BSI report and affect central aspects of the authentication logic or local system security.
For CISOs, this means that Windows Hello for Business must be critically assessed as a standalone authentication solution. A weighing of risk mitigation through passwordless authentication against the newly identified vulnerabilities is required. Organizations should review the BSI recommendations for implementation and, if necessary, introduce additional security measures to mitigate known attack vectors.
