EC-Council 312-85 Exam - Topic 5 Question 39 Discussion

Posted by Amber on Jan 27, 2026 at 02:35 PM

An analyst is conducting threat intelligence analysis in a client organization, and during the information gathering process, he gathered information from the publicly available sources and analyzed to obtain a rich useful form of intelligence. The information source that he used is primarily used for national security, law enforcement, and for collecting intelligence required for business or strategic decision making.

Which of the following sources of intelligence did the analyst use to collect information?

Suggested Answer: C

The analyst used Open Source Intelligence (OSINT) to gather information from publicly available sources. OSINT involves collecting and analyzing information from publicly accessible sources to produce actionable intelligence. This can include media reports, public government data, professional and academic publications, and information available on the internet. OSINT is widely used for national security, law enforcement, and business intelligence purposes, providing a rich source of information for making informed decisions and understanding the threat landscape.

I recall that national security sources often include things like news articles and public records, so maybe it’s OSINT after all.

I feel like it could also be related to SIGINT, but that usually involves signals rather than just public information, right?

This sounds a lot like the practice questions we did on intelligence sources. I remember something about government databases being a key part of it.

I think the analyst might have used open-source intelligence (OSINT), but I'm not entirely sure if that's the right term for it.

This is a tricky one, but I think I've got it. Based on the information provided, the analyst likely used open-source intelligence (OSINT) to gather the data. The description fits OSINT's use for both national security and business purposes.

Okay, I've got a strategy for this. I'll first identify the key details in the question, like the use for national security and business decisions. Then I'll match those to the common intelligence source types to determine the best answer.
FE
Felice 9 months ago
I'm a bit confused by the wording here. The description sounds like it could be referring to multiple types of intelligence. I'll need to carefully read through the options and think about how each one matches the details given.
HI
Hillary 9 months ago
Hmm, the question mentions national security and business decision-making, so I'm thinking this could be open-source intelligence (OSINT). I'll need to double-check the characteristics of OSINT to be sure.
