![]() When to use a rule-based access control model If an employee fails to meet all these criteria access will be denied. Attributes can include desired actions, job roles and the classification of the object or location in question. Attribute-based access control ( ABAC)Īttribute-based access control (also referred to as a policy-based access control method) is a methodology in which permissions are granted based on the evaluated attributes or characteristics of the employee rather than only their specific role. ![]() This means that once the end user has access to a location or a digital system, they’re able to grant the same privileges to any other person at their own personal discretion. ![]() In contrast to MAC, discretionary access control models describe a system in which any user granted access permissions by an administrator can edit and share those permissions with other members of an organization. This model is commonly used by organizations with high-level security needs, like government agencies and financial institutions, as access to confidential areas and data must be highly controlled and traceable. Mandatory access control is the strictest configuration organizations can deploy in which all access decisions are made by one individual with the authority to confirm or deny permissions. Simply put, levels of access are determined by the user’s job title rather than other predefined rules such as time, frequency of use or other similarly measurable variables. Role-based access control is an operational configuration for physical and cyber entry point management designed to grant access permissions based only on the role of the user within an organization. What is role-based access control? ( RBAC) In other words, if the user does not meet a set of predefined access criteria, they will be locked out of the access control network regardless of their level of security clearance. Rule-based access control is used to manage access to locations, databases and devices according to a set of predetermined rules and permissions that do not account for the individual’s role within the organization. These access control models describe the way in which an installed security system is instructed to operate, including the parameters that must be met to grant building, room or elevator access, the way that unique user permissions are understood and the ruleset used to inform wider security policies.Ĭhoosing the most appropriate access control models will require the system administrator or business owner to consider the unique needs of the access control system installation, including the type and size of the building, the number of individuals requiring regular access, the intended variability of granted permissions and the overall level of on-site security deemed necessary for the organization. Most access control methods can be categorized using one (or more) of these five models or access control lists:
