Exam NSE8 topic 1 question 6 discussion

A company wants to protect against Denial of Service attacks and has launched a new project. They want to block the attacks that go above a certain threshold and for some others they are just trying to get a baseline of activity for those types of attacks so they are letting the traffic pass through without action. Given the following:
- The interface to the Internet is on WAN1.
- There is no requirement to specify which addresses are being protected or protected from.
- The protection is to extend to all services.
- The tcp_syn_flood attacks are to be recorded and blocked.
- The udp_flood attacks are to be recorded but not blocked.
- The tcp_syn_flood attacks threshold is to be changed from the default to 1000.
