On February 16, 2016 IBM announced authentication enhancements for z Systems, including a new product IBM Multi-Factor Authentication for z/OS (5655-162), with a planned availability date of March 25, 2016.
IBM z/OS Security Server Resource Access Control Facility (RACF) provided enabling infrastructure updates for z/OS V2R1 and V2R2.
IBM Security zSecure suite provided supporting updates for zSecure 2.1, 2.1.1, and 2.2.
Multi-Factor Authentication raises the level of assurance of mission-critical systems by requiring authentication with multiple factors during the logon process.
Each authentication factor must be from a separate category of credential types:
1) Something you know (e.g. a password or PIN code),
2) Something you have (e.g. an ID badge or a cryptographic key),
3) Something you are (e.g. a fingerprint or other biometric data).
More details can be located through this blog entry by Jeroen Tiggelman on the Service Management Connect - System z blog.
