It's been a constant for the last couple of decades - I can't count the number of times I've been involved in mitigating penny-ante DDoS attacks which succeeded *solely* due to state exhaustion on stateful firewalls, 'IPS' devices, and load-balancers.
I've seen a 20gb/sec commercial stateful firewall taken down by a 3mb/sec spoofed SYN-flood.
I've seen a 10gb/sec commercial load-balancer taken down by 60 second at 6kpps - yes, 6kpps - of HOIC.
And so on, and so forth.
'Dismiss' it all you like, but it's a real issue, as others on this list know from bitter experience.
Hi, Roland is right. 99% of network based security products are pure snake oil. Patch you servers, know your base line, statelessly filter unwanted traffic, rtbh as needed, sleep well at night. Bye.
