I thought IPSec was mainly for security, not DDoS protection.

Wait, are we sure traffic scrubbers are enough?

Disabling NAT-T? That sounds risky, not a good idea.

I have a vague recollection that IPSec is more about securing connections rather than preventing DDoS. I’m leaning towards option C.

I practiced a similar question where implementing traffic scrubbers was highlighted as a key strategy. That might be the right answer here.

I'm not entirely sure, but I feel like DNSSEC is more about securing DNS rather than directly mitigating DDoS attacks.

Okay, I've got a strategy for this. DDoS attacks are all about overwhelming the target system with traffic, so the key is to filter and scrub that traffic before it reaches the portal. That's why C is the best answer - the traffic scrubbers at the ISP level can help mitigate the DDoS attack.

Hmm, I'm a little unsure about this one. I know DNSSEC and IPSec are security protocols, but I'm not sure how they relate to mitigating DDoS attacks specifically. I'll have to think this through carefully.

This question seems pretty straightforward. I think the answer is C - implementing traffic scrubbers on the upstream ISP connection.

I'm pretty confident the answer is C. Disabling NAT-T or requiring IPSec might help with other security concerns, but they don't directly address the DDoS problem. Implementing traffic scrubbers at the ISP is the most effective way to deal with a distributed denial of service attack.

Okay, I've got a strategy for this. I'll focus on the common security problems like default credentials, privilege escalation, and file system permissions.

DNSSEC, really? I thought we were trying to stop DDoS, not secure our DNS. Traffic scrubbers all the way, baby!

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?
