I found this statement describing ICMP Flood attacks and I am confused about the term "Security Zone" being used in it.
" Once the ICMP threshold is reached, the server will stop accepting any further ICMP ECHO requests from all addresses in the same security zone. "
What does "same security zone" mean ?
Thanks.
Edit:
Full text - " After the ICMP threshold is reached, the router rejects further ICMP echo requests from all addresses in the same security zone for the remainder of the current second and the next second as well. "
