Sam works as an analyst in an organization named InfoTech Security.

Sam's mistake was using threat intelligence from sources that he did not verify for reliability. Relying on intelligence from unverified or unreliable sources can lead to the incorporation of inaccurate, outdated, or irrelevant information into the organization's threat intelligence program. This can result in "noise," which refers to irrelevant or false information that can distract from real threats, and potentially put the organization's network at risk. Verifying the credibility and reliability of intelligence sources is crucial to ensure that the data used for making security decisions is accurate and actionable.References:
