IBM zSecure Command Verifier

Master RACF command control with IBM zSecure Command Verifier in this hands-on course by Gentex Training Center.

Date & Location

Introduction

In high-security environments powered by z/OS, unauthorized or misused RACF commands can lead to serious vulnerabilities or compliance violations. IBM zSecure Command Verifier is an advanced security extension that ensures command-level verification for RACF operations. It adds a crucial layer of control by checking the authorization of RACF commands before they are executed—reducing the risk of human error, privilege misuse, and accidental changes to sensitive security profiles.

This 5-day training course provided by Gentex Training Center offers a complete understanding of how to implement, configure, and utilize IBM zSecure Command Verifier. Participants will explore its integration with RACF, set command authorization policies, analyze security impacts, and use best practices for managing access and compliance. The course combines structured learning with guided labs to ensure practical skill development.
