Comprehensive and Detailed Explanation From Exact Extract:

The identification of advanced persistent threats (APTs) is best supported by timely and relevant external information. Reviewing information from threat intelligence sources enables the organization to detect emerging threats quickly and accurately, reducing the mean time to identify APTs. While internal audits and KRIs are important, they typically focus on internal controls and risk monitoring rather than external threat detection. Thorough documentation of risk scenarios supports risk assessment but does not directly reduce detection time. Therefore, leveraging threat intelligence is the most effective approach for early identification of sophisticated threats.
