Traffic Management Filters: Flow-Based vs. Non-Flow Based

Play an AI-generated podcast conversation about this lesson

What is the purpose of creating a Traffic Management Filter (TMF) to trust vulnerability scanners or internal IT monitoring scripts?

To avoid unnecessary events and consumption of inspection resources (correct)

To overshadow actual attacks

To consume inspection resources

To block unnecessary events and streams

How can the use of Traffic Management Filters (TMFs) benefit a system?

By generating events to track traffic

By increasing the consumption of inspection resources

By reducing inspection overheads and performance protection alerts (correct)

By causing unnecessary events

In what direction does the traffic flow for the network scanner located at 192.168.1.200 when passing through IPS?

In both directions A to B and B to A (correct)

Segment 1A to 1B

Segment 6B to 6A

Segment 1B to 1A
