XACML

XACML (eXtensible Access Control Markup Language) is a standard for defining and enforcing access policies in computer systems. It helps organizations decide who can do what with their digital resources—like accessing files, applications, or data—based on rules such as user roles, location, or time. XACML uses a structured language to specify these policies clearly, allowing systems to automatically evaluate requests and grant or deny access accordingly. This ensures secure, consistent, and flexible control over sensitive information across different platforms and services.
