'''Attribute-based access control''' ('''ABAC'''), also known as '''policy-based access control''' for [[Identity management|IAM]], defines an access control paradigm whereby access rights are granted to users through the use of policies which combine attributes together.<ref>{{Cite web|last=Computer Security Division|first=Information Technology Laboratory|date=2016-05-24|title=Attribute Based Access Control {{!}} CSRC {{!}} CSRC|url=https://csrc.nist.gov/Projects/Attribute-Based-Access-Control|access-date=2021-11-25|website=CSRC {{!}} NIST|language=EN-US}}</ref> The policies can use any type of attributes (user attributes, resource attributes, object, environment attributes etc).
This model supports Boolean logic, in which rules contain "IF, THEN" statements about who is making the request, the resource, and the action. For example, IF the requester is a manager, THEN allow read/ write access to sensitive data.
