XACML (eXtensible Access Control Markup Language)

XACML, or eXtensible Access Control Markup Language, is a standard used to manage who can access specific resources and under what conditions. Imagine it as a set of rules that defines who is allowed to enter a building based on various criteria, like their identity, the time of day, or their reason for visiting. XACML helps organizations create and enforce these access rules in a digital environment, ensuring that sensitive information is protected while allowing authorized users to access it easily. It's widely used in software and web services for secure access management.
