Resource Access Control Facility

Resource Access Control Facility or RACF provides the tools to manage user access to critical resources. RACF is an add-on software product that provides basic security for a mainframe system (examples of other security software packages include ACF2 and Top Secret, both from Computer Associates).

RACF protects resources by granting access only to authorized users of the protected resources. RACF retains information about users, resources, and access authorities in special structures called profiles in its database, and it refers to these profiles when deciding which users should be permitted access to protected system resources.  

To help your installation accomplish access control, RACF provides the ability to:


  • Identify and authenticate users
  • Authorize users to access protected resources
  • Log and report various attempts of unauthorized access to protected resources
  • Control the means of access to resources


Let help you with your MVS OS/390 z/OS RACF Administration.
