Analyzing an asset in an unprotected state followed by considering current countermeasures is called ______ analysis.

The term describing the process of analyzing an asset in an unprotected state and then evaluating the current countermeasures applied to that asset is known as regressive analysis. This analytical approach focuses on understanding the vulnerabilities of an asset before identifying the protective measures that are in place. By examining the unprotected state first, one can better gauge the effectiveness of existing countermeasures and make informed decisions on enhancing security protocols.

In the realm of anti-terrorism, this type of analysis is essential because it allows security professionals to pinpoint weaknesses in their systems and improve their overall security posture. Understanding how the asset would fare without protection provides insights into potential risks and gaps, leading to more effective counter-terrorism strategies.

The terms mentioned in the other answer choices do not accurately reflect this specific analytical approach. Linear analysis, for example, typically refers to a straightforward cause-and-effect approach that might not account for vulnerabilities in the protective measures. Re-evaluative analysis suggests a reassessment of previous evaluations, which does not emphasize the initial unprotected state strongly. Cumulative analysis often looks at accumulative impacts or factors over time rather than starting from an unprotected state to gauge existing countermeasures. Therefore, regressive analysis is the term that aligns precisely with the definition
