What You'll Learn
Access Control Models is a critical topic in the CISSP exam, as it covers the fundamental principles and mechanisms that govern how users, processes, and resources are granted or denied access to information and systems. Understanding these models is essential for designing, implementing, and managing secure access control systems that protect against unauthorized access and minimize the risk of data breaches or cyber attacks. This topic encompasses a range of conceptual models, such as Discretionary Access Control (DAC), Mandatory Access Control (MAC), and Role-Based Access Control (RBAC), as well as practical considerations for access control policy, implementation, and enforcement.
Key Concepts
Discretionary Access Control (DAC)
A model in which the owner of an object (e.g., a file, application, or resource) has the ability to determine who can access that object and what actions they can perform. The access control decisions are made based on the identity of the user or the groups to which the user belongs.
Mandatory Access Control (MAC)
A model in which access control decisions are made based on predefined security labels or classifications assigned to subjects (users, processes) and objects (files, resources). The security labels are used to enforce a strict, centralized access control policy that cannot be overridden by individual users.
Role-Based Access Control (RBAC)
A model that grants access permissions to users based on their assigned roles within an organization. Roles are defined based on job functions and responsibilities, and users are granted access to resources based on their roles, rather than their individual identities.
Attribute-Based Access Control (ABAC)
A model that grants access permissions to users based on a combination of attributes, such as the user's identity, role, location, time, and other contextual information. Access control decisions are made dynamically based on the evaluation of these attributes against a predefined access control policy.
Least Privilege
The principle of granting users, processes, and systems the minimum amount of access permissions required to perform their intended functions. This helps minimize the risk of unauthorized access or privilege escalation.
Common Mistakes to Avoid
- Confusing the different access control models and their key characteristics
- Failing to understand the concept of least privilege and how it applies to access control
- Overlooking the importance of access control policies and their role in defining and enforcing access control rules
- Underestimating the complexity of implementing and maintaining effective access control systems, especially in large or dynamic environments
- Neglecting to consider the impact of new technologies, such as cloud computing and mobile devices, on access control requirements and best practices
Study Tips for Access Control Models
Thoroughly understand the definitions, features, and differences between the core access control models (DAC, MAC, RBAC, ABAC)
Practice applying the principles of least privilege and separation of duties when designing access control systems
Review real-world examples and case studies to better understand how access control models are implemented in practice
Stay up-to-date with the latest trends, technologies, and best practices in access control, as the field is constantly evolving
