XACML (eXtensible Access Control Markup Language) is a standard for expressing access control policies in XML. It defines a framework for managing and enforcing access control decisions, allowing organizations to specify who can perform specific actions on particular resources under defined conditions.

About Xacml
XACML was developed by the OASIS (Organization for the Advancement of Structured Information Standards) consortium in 2003. It was created to provide a standardized way to express and enforce access control policies across various systems and applications, addressing the need for a consistent and interoperable approach to authorization management.
Strengths of XACML include its flexibility, extensibility, and ability to handle complex access control policies. Weaknesses are its complexity and potential performance issues in large-scale implementations. Competitors include OAuth, which is simpler for authorization delegation, and ABAC (Attribute-Based Access Control) systems that might offer more straightforward implementations for certain use cases.
