Let's imagine three companies (A, B and C), all competing in a challenging global environment. Company A and B are working together in developing a product that will generate a major competitive advantage for them. Company A has a secure DNS server while company B has a DNS server vulnerable to spoofing. With a spoofing attack on the DNS server of company B, company C gains access to outgoing e-mails from company B. How do you prevent DNS spoofing? (Select the Best Answer.)

B seems irrelevant. Timeouts don’t prevent spoofing.

A could help too, but not as effective as C.

D is important, but it won't stop spoofing directly.

Wait, disabling DNS timeouts? That sounds risky...

I bet the guy who came up with option B was the same one who thought unplugging the router would fix the internet.

D) Disable DNS Zone Transfer? Nah, that's just going to create more problems than it solves.

A) Install DNS logger? Seriously? That's like trying to catch a thief by watching the security camera footage after they've already stolen everything.

Disabling DNS timeouts (B) won't help, that's just asking for trouble.

I’m pretty certain that disabling DNS timeouts isn’t a good preventive measure against spoofing. I’d go with DNS Anti-spoofing, but I wish I had more clarity on this.

I’m leaning towards installing DNS logger to track packets, but I recall that might not directly prevent spoofing. It’s tricky!

This question feels familiar; I think we had a practice question about DNS vulnerabilities. Disabling DNS Zone Transfer seems like it could help, but I’m not confident.

I remember studying DNS security, and I think installing DNS Anti-spoofing could be the right choice, but I'm not entirely sure if it's the only solution.

Okay, I think I've got it. The anti-spoofing option is the best choice because it directly addresses the root cause of the problem - the vulnerability in company B's DNS server. Disabling timeouts or zone transfers might help in other scenarios, but for this specific issue, the anti-spoofing solution is the way to go.

Installing a DNS logger could help track the vulnerable packets, but it doesn't actually prevent the spoofing attack from happening in the first place. I think the anti-spoofing solution is the way to go here.

Hmm, I'm a bit confused. Disabling DNS timeouts or zone transfers doesn't seem like it would actually stop the spoofing attack. I'm leaning towards the anti-spoofing option, but I want to make sure I understand it fully before selecting it.

I think the key here is to focus on preventing the DNS spoofing attack. Option C, "Install DNS Anti-spoofing", seems like the most direct way to address that.

True, but it’s more of a reactive measure, not preventive.
