24 Questions
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
How can the use of Traffic Management Filters (TMFs) benefit a system?
By reducing inspection overheads and performance protection alerts
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
What is the reason for creating a 4-way trust instead of a single rule for the network scanner?
To catch all possible directions in the environment for both scan and the response
What does a Traffic Management Filter (TMF) use when ordering its rules?
First match
What type of traffic did the staff initially use Exceptions on attack filters for?
Web server traffic
What is the main consequence of Trusting all traffic to and from a network scanner?
Reduced performance protection alerts
How does creating a Traffic Management Filter (TMF) for trust help in protecting web servers?
By reducing unnecessary resource consumption and events related to monitoring scripts
What is the main focus of flow-based inspection filters?
Inspecting packet headers and payload data
What are non-flow-based inspection filters also known as?
User-defined filters
Which type of filter looks at the overall behavior of traffic over time?
Algorithmic filters
What is the primary focus of header-based filters?
Examining IP header information
Which type of filter specifically focuses on detecting vulnerabilities?
Vulnerability filters
What do reconnaissance filters primarily aim to detect?
Port scans and host sweeps
Which type of filter looks at the IP header for detecting specific types of traffic?
Header-based filters
What is the distinguishing feature of flow-based inspection filters compared to non-flow-based ones?
They inspect packet headers and payload data
What is the purpose of creating a 4-way trust for traffic management filters in this scenario?
To ensure that all possible directions of traffic are accounted for
What does creating a 'virtual pipe' achieve when using rate-limiting?
It groups together different types of traffic for easier management
In what scenario would it be advisable to create multiple rules instead of a single rule for traffic management?
When the exact flow of traffic through each IPS device is unknown
What happens if you assign the same rate-limiting Action Set to different filters?
The flows matching those filters will share the same bandwidth restriction
Why might it be necessary to create two Action Sets with different names but the same rate limit value?
To ensure that certain types of traffic have their own dedicated bandwidth restriction
What is the benefit of using a 4-way trust instead of a single rule for traffic management?
It ensures that all possible directions of traffic are included
What is the purpose of assigning a rate-limiting Action Set to a Filter?
To group together different types of traffic under one limitation
When is it advisable to create multiple rules for traffic management?
When there are variations in how the traffic traverses each IPS device
Test your understanding of traffic management filters with a focus on flow-based vs. non-flow-based filters. This quiz covers flow-based inspection filters, flow-tuples, and the differences between flow-based and non-flow-based protection.
