I think they trying to trick you... I am looking at the key words Response vs Remediation. Response - Incident response activities include detection, analysis, containment, eradication, recovery, communication, and documentation. Remediation - Remediation activities include applying patches, fixing misconfigurations, updating security policies, improving access controls, and implementing other corrective measures.

Not sure if A or C. I'm leaning more to A. The term 'mean time to remediate' is a definition - at least in comptia study guide! It is used in the IR metrics chapter. So we have it in this order: mean time to detect mean time to respond mean time to remediate I would say "mean time to respond" does not include patching, but in it is in the "mean time to remediate", so that is why I choose A.

I think the more viable answer is Mean Time to Remediate. Remediation incorporates the response and determines the average time it is resolved by. Response does not determine when the issue is remediated, simple that it is being responded to. Since Remediation incorporates response and is below the 45 day window of exploitations this seems like the best answer that takes away all guesswork.

A mean time to remediate of 30 days implies that the organization aims to remediate vulnerabilities within 30 days of their discovery. Since exploitation of new attacks tends to occur approximately 45 days after a patch is released, aiming for a mean time to remediate of 30 days ensures that vulnerabilities are patched before attackers have the opportunity to exploit them.

A is correct. MTTR involves the entire process, detection is only part .

C is correct. When you have a response policy that requires a review at least every 15 days, it will help the company recognize all newly patched exploitations within that timeframe, as a mean time to respond (MTTR) of 15 days is required. When you discover a risk, your team will fix it right away with just a click of a button to update the patch released 15 days ago. The goal is to find out about it ASAP. It is nonsensical to compare mean time to remediate or respond in this context. Are you going to sit there after you have responded to it and watch because no-one told you to remediate it, or act honorably, honestly, justly, and responsibly by fixing the issue as soon as possible with your professional responsibility?

Guys this is C 100%, this question is eluding to the fact that the company are taking too long to patch vulnerable systems. A mean time to respond of 15 days is much better & faster than a mean time to remediate of 30 days.

Mean time to respond of 15 days Faster reaction to threats Somewhat relevant - but patching speed remains crucial. Therefore answer should be A

What is MTTR - Mean Time to Respond/Remediate? MTTR is the amount of time it takes an organization to neutralize an identified threat or failure within their network environment. Threat remediation is the process organizations use to identify and resolve threats to their network environment.

To best protect the organization from exploitation of new attacks, it's important to reduce the time between the release of patches and their implementation within the organization. This is known as the "time to remediate" or "mean time to remediate" (MTTR). Therefore, the option that aligns with this objective is: A. A mean time to remediate of 30 days A shorter mean time to remediate ensures that patches are applied more quickly, reducing the window of vulnerability and the likelihood of exploitation. Options B and C, with longer timeframes, would increase the organization's exposure to potential attacks. Third-party application testing (option D) is important but is not directly addressing the time it takes to apply patches after they are released.

Scored around 820. Went with A

Mean time to respond refers to the average time it takes an organization to respond to a security incident after it has been detected. A shorter mean time to respond is generally associated with more effective incident response and containment.

It is A. There is no such phrase in security as 'mean time to remediate'. MTTR = mean time to respond, and it includes remediation implicitly.

Key statement is "would best protect this organization" So the earlier a vulnerability is detected the better.

In summary, the correct answer is "30 days average time to remediate" because it focuses on the time frame for effective application of fixes and patches, which is critical to cybersecurity, rather than just the initial response to an alert. This helps ensure that vulnerabilities are patched in a timely manner and reduces exposure to security risks.

C. A mean time to respond of 15 days Explanation: A "mean time to respond" (MTTR) metric measures the average amount of time it takes for an organization to respond to and address security incidents, including applying patches. In this scenario, a mean time to respond of 15 days indicates that the organization is capable of responding to new vulnerabilities and applying patches within a relatively short timeframe.

I was also questioning this. ChatGPT says "The correct answer is C. A mean time to respond of 15 days. The scenario described indicates that attackers are exploiting vulnerabilities approximately 45 days after a patch is released. This suggests that organizations are taking too long to respond to and apply patches, leaving a window of opportunity for attackers to exploit those vulnerabilities. A "mean time to respond" (MTTR) of 15 days would be the most effective in reducing the risk of exploitation. MTTR refers to the average time it takes an organization to respond to and mitigate a security incident or vulnerability once it has been detected. By responding within 15 days, the organization would be able to address vulnerabilities and apply patches more quickly, reducing the likelihood of exploitation."
