NIST Guide Aims to Ease Access Control with Attribute-based Access Control. NIST Special Publication 800-162 aims to encourage information sharing while preserving control over access to data. ABAC is a logical access control methodology where authorization to perform a set of operations is determined by evaluating attributes associated with the subject, such as a user or employee; an object; and requested operations. The flexibility of the ABAC model allows the greatest breadth of subjects to access the great breadth of objects.”]
