Final answer:
An Access Control rule specifies who can access resources, what resources they can access, and how they can interact with these resources. These rules form the core of a security policy and are managed through various forms of Access Control Lists or systems like RBAC or ABAC.
Step-by-step explanation:
An Access Control rule specifies three things: who is allowed or denied access, what resources they are allowed or denied access to, and how they can interact with the resources. Here are more details on each:
- Who – This part of the rule determines which users or groups of users are subject to the rule.
- What resources – This defines the specific systems, networks, applications, files, or other resources that the rule applies to.
- How – This specifies the type of access that is allowed or denied, such as read, write, execute, or full control.
These rules are a critical part of an organization’s security policy and are often managed through an Access Control List (ACL) or a more dynamic form of access control such as Role-Based Access Control (RBAC) or Attribute-Based Access Control (ABAC).
