Guide: Context-Based Access Control - CISSP Concept

What is Context-Based Access Control?
Context-based access control, also known as CBAC, is a security feature that provides increased control over network access. It is primarily used to allow or deny access to network resources based on certain conditions or contexts.

Why it is important?
CBAC is important because it allows for more granular control over network access. It provides dynamic access control based on application-specific, session-specific, or context-specific information. This can greatly enhance network security and prevent unauthorized access.

How it works?
CBAC works by inspecting the traffic that flows through network points and applying rules or policies based on the context of the traffic. This context could include details like the user's role, the time of day, the location, or the type of traffic.

Exam Tips: Answering Questions on Context-Based Access Control
When answering questions on CBAC, remember:
- Understanding the context: Ensure you understand the concept of 'context' in this setting - factors like role, location, type of traffic etc.
- Feature Details: Understand the underlying features of CBAC and how it enhances network security.
- Working Mechanism: Be clear on how CBAC works, including how it inspects traffic and applies policies.
- Real-World Applications: Consider how CBAC is applied in real-world scenarios - this will assist in understanding conceptual and applied questions.
