The SecOps Group Exam CNSP Topic 8 Question 3 Discussion

Actual exam question for The SecOps Group's CNSP exam
Question #: 3
Topic #: 8
[All CNSP Questions]

You are performing a security audit on a company's infrastructure and have discovered that the domain name system (DNS) server is vulnerable to a DNS cache poisoning attack. What is the primary security risk?

Show Suggested Answer Hide Answer
Suggested Answer: A

DNS cache poisoning, also known as DNS spoofing, involves an attacker injecting false DNS records into a resolver's cache, altering how domain names resolve.

Why A is correct: The primary risk is that an attacker can redirect users to malicious websites (e.g., phishing or malware sites) by poisoning the DNS cache with fake IP addresses. This can lead to credential theft, data exfiltration, or malware distribution. CNSP identifies this as the core threat of DNS cache poisoning, aligning with real-world attack vectors.

Why other option is incorrect:

B . Manipulate the cache of the web server or proxy server: This describes web cache poisoning, a different attack targeting HTTP caches, not DNS servers. DNS cache poisoning affects DNS resolution, not web or proxy server caches directly.

That's also a valid point. It could lead to users accessing fake websites or receiving false information.

But what about the risk of an attacker manipulating the cache to return incorrect content for a specific URL or web page?

I agree with Merrilee. That's a major concern with DNS cache poisoning attacks.

Hmm, this is a tough one. But I think A is the way to go. Redirecting traffic to a shady site sounds like a recipe for disaster. Unless the attacker is planning to fill the cache with cat memes, in which case I'm all for it.

A) Redirecting traffic to a shady site does sound dangerous. We definitely don't want sensitive information falling into the wrong hands.

Haha, this is a classic 'pick your poison' kind of question. I'll have to go with A though, because who knows what kind of nefarious schemes the bad guys could cook up on that malicious site. I'd rather not find out the hard way!

I'd have to go with B. Manipulating the cache to serve up false content could be just as dangerous, if not more so. Imagine an attacker hijacking a banking website, yikes!

Definitely option A. Redirecting traffic to a malicious site is the biggest risk here. That could lead to some serious data breaches and identity theft.
