RACF (Resource Access Control Facility)

RACF (Resource Access Control Facility) is a security tool used to protect data and resources on IBM mainframe computers. It controls who can access, modify, or view sensitive information by setting rules and permissions for users and groups. RACF helps ensure only authorized individuals can perform specific actions, safeguarding the system from unauthorized access, data breaches, and misuse. It acts like a digital security guard, managing access rights and enforcing security policies to maintain the integrity and confidentiality of critical enterprise data.
