XACML

XACML stands for eXtensible Access Control Markup Language. It is a language for creating rules that control who can see or use certain things, such as websites or documents. For example, a company might use XACML to create rules that say which employees are allowed to access certain parts of their website or certain documents. XACML helps companies make sure that only the people who are supposed to have access to their information actually do get access.
