Mainframe Security
System access should precisely match user and application responsibilities. SAI Technologies helps strengthen z/OS security across RACF, CA-ACF2 and CA-Top Secret, operating RACF as the authoritative security layer for z/OS while connecting security logs into contracted SOC monitoring tools such as Microsoft Sentinel.
The business problem
Years of role changes, obsolete service accounts and legacy software integrations often leave excess administrative access unmonitored on core mainframe environments.
How SAI Technologies approaches the work
Map users, service IDs, dataset profiles, transactions and privileged z/OS access paths.
Review RACF, ACF2 and TSS configurations, MFA policies and joiner-mover-leaver workflows.
Connect SMF audit streams with contracted 24/7 SOC threat-detection systems.
Design and execute approved access remediation, role cleanup and entitlement structures.
Document exception handling, regulatory evidence and support handoffs.
Illustrative industry use case
A payment processor integrates partner portals with back-end mainframe systems. SAI Technologies reviews API permissions, dataset security profiles and continuous SOC logging requirements to enforce least-privilege standards.
A practical first SOW
Audit RACF or ACF2 rules for selected critical datasets, identify excess privileged access, integrate SMF log streams with SOC tools and pilot approved remediation.
