When dealing with computer and information system security, the use of access controls limit system or user access based on a specified set of criteria.
Lattice-Based Access Control (LBAC) is a complex method for limiting information access based on any combination of objects (such as resources, computers, and applications) and subjects (such as individuals, groups or organizations).
LBAC is known as a more specific set of access control restrictions and is based on the lesser complex model known as Role-Based Access Control (RBAC).
