A tabletop exercise is the most appropriate method because the objective is to collaboratively validate an updated incident-response plan with relevant stakeholders. Tabletop exercises are discussion-driven simulations in which participants work through a realistic incident scenario, explain their expected actions, identify dependencies, evaluate communication paths, and expose procedural or organizational gaps without performing disruptive live attacks.

CISA states that tabletop exercises are used to validate or improve understanding of plans and procedures, rehearse concepts, assess incident-response and recovery requirements, and identify areas requiring improvement. CISA also provides Tabletop Exercise Packages specifically to help stakeholders conduct collaborative exercises and organizational discussions.

A red-team event involves active adversary simulation and focuses primarily on testing defensive capabilities against realistic attacker behavior. A penetration test evaluates exploitable technical weaknesses. Security awareness training teaches users security knowledge but does not collaboratively validate incident-response roles, escalation paths, communications, and decision-making.

Because the manager recently made significant plan updates , a tabletop exercise provides a controlled mechanism for all stakeholders to determine whether those procedures actually function as intended before a real incident occurs.

The Diamond Model of Intrusion Analysis is specifically suited to visually representing relationships between a threat actor, the infrastructure used during an intrusion, the actor's capabilities, and the victim. Its four principal vertices are adversary, infrastructure, capability, and victim . IP addresses and network services naturally map to infrastructure, while malware and attack tools map to capability.

The original Diamond Model describes an intrusion event through these four interconnected features and uses their relationships to support documentation, correlation, and analysis of malicious activity. This makes it particularly useful when the analyst wants to visualize intelligence rather than simply place activity into chronological stages.

EPSS predicts the probability that a vulnerability will be exploited and therefore does not model threat-actor infrastructure. The Cyber Kill Chain represents progressive stages of an intrusion, making it useful for understanding attack progression but less suitable for relational visualization. MITRE ATT & CK provides detailed behavioral information on adversary tactics and techniques; MITRE itself notes that ATT & CK and the Diamond Model are complementary, with the Diamond Model particularly useful for clustering and relating intrusion information.

Software Composition Analysis (SCA) is specifically designed to identify third-party and open-source components incorporated into software. It can enumerate libraries and dependencies, identify their versions, associate components with known vulnerabilities, and provide licensing information. This directly satisfies the legal team's requirement to determine whether the codebase contains open-source or commercially licensed libraries.

CISA's software supply-chain guidance recognizes software composition analysis and software bills of materials as mechanisms for obtaining visibility into software components. CISA guidance also notes that SBOM information can include both open-source and commercial third-party software and licensing information.

SAST examines source or compiled code for security weaknesses such as unsafe functions, data-flow problems, or coding vulnerabilities, but dependency licensing is not its primary purpose. DAST tests a running application from the outside and generally cannot inventory the complete component dependency tree. RASP operates within a running application to detect or prevent attacks. Credentialed infrastructure scanning identifies system-level vulnerabilities and configuration issues rather than software-license composition.

The strongest clue is the requirement to identify libraries and their licensing status , which directly maps to SCA.
