Bro scripts to detect network attacks


I’m running Bro in my network, and I want to perform attacks to test its capabilities and create alert information.
I choose to use SYN Flood Attack and ARP Spoofing Attack, can anyone tell me where to find these scripts?

Any help would be great. Thank You.

It looks like there’s a syn flood detection script here:
and an arp spoofing detection script here:

But I’m not sure if there is anything more up-to-date.
