Requiring IPSec for all connections? That's overkill and will just frustrate our users. Let's keep it simple with the traffic scrubbers.

I'm not sure about disabling NAT-T at the firewall, that could cause connectivity issues for some users. I'd go with the traffic scrubbers too.

I'm not sure about that. Wouldn't implementing DNSSEC on Internet-facing name servers also help in mitigating DDoS attacks by ensuring the integrity of DNS data?

I agree with Maurine. Implementing traffic scrubbers can help filter out malicious traffic and protect the portal from DDoS attacks.

I think the IoT portal administrator would most likely use traffic scrubbers on the upstream ISP connection to mitigate DDoS attacks.

Option C sounds like the best approach to me. Scrubbing the traffic at the ISP level can effectively mitigate DDoS attacks without causing disruption to the portal.
