Comprehensive and Detailed Explanation From Exact Extract of Forescout Platform Administration and Deployment:
According to the Forescout Platform Administration and Deployment Documentation, the best practice to pass an endpoint from one policy to another is to use SUB-RULES.
Sub-Rules and Policy Routing:
Sub-rules are conditional branches within a Forescout policy that allow for sophisticated endpoint routing and handling. When an endpoint matches a sub-rule condition, it can be directed to perform specific actions or be passed to another policy group for further evaluation.
Key Advantages of Using Sub-Rules:
Granular Control - Sub-rules enable precise segmentation of endpoints based on multiple properties and conditions
Hierarchical Processing - Once an endpoint matches a sub-rule, it proceeds down the sub-rule branch; later sub-rules of the policy are not evaluated for that endpoint
Efficient Endpoint Routing - Sub-rules allow endpoints to be efficiently routed to appropriate policy handlers without evaluating unnecessary conditions
Policy Chaining - Sub-rules facilitate the logical flow and routing of endpoints through multiple policy layers
Best Practice Implementation:
The documentation emphasizes that when designing policies for endpoint management, administrators should:
Use sub-rules to create conditional branches that evaluate endpoints against multiple criteria
Route endpoints to appropriate policy handlers based on their properties and compliance status
Avoid using simple property-based routing when complex multi-step evaluation is needed
Why Other Options Are Incorrect:
A. Use operating system property - While OS properties can be used in conditions, they are not the mechanism for passing endpoints between policies
C. Use function property - Function properties are not used for inter-policy endpoint routing
D. Use groups - While groups are useful for organizing endpoints, they are not the primary best practice for passing endpoints between policies
E. Use policy condition - Policy conditions define what endpoints should be evaluated, but sub-rules provide the actual routing mechanism
