16. Frage
Background: You are scoping an engagement for Ashcombe Retail Bank, a mid-sized UK bank preparing for its first CBEST engagement. During the scoping workshop, the Head of Digital Channels strongly advocates for an objectives-based ("flag") approach, proposing a single objective: "achieve unauthorised funds transfer capability in the core payments system." The Head of Operational Resilience, in the same meeting, separately advocates for a crown-jewels (asset-based) approach explicitly listing seven named critical systems that must each be individually assessed, arguing the board specifically wants to see coverage confirmation against each one for their operational resilience self-assessment.
Both stakeholders are Control Group members, and neither is aware the other has a different underlying preference until this workshop, where the disagreement becomes evident in real time. The engagement's resourcing (agreed with the Bank of England as broadly appropriate for a first CBEST engagement of this bank's size) is not large enough to comfortably deliver a deep, patient, objectives-based campaign against one target AND a full individual assessment of all seven named systems within the available testing window.
Question: As the Red Team Manager facilitating this scoping workshop, how would you help the Control Group resolve this disagreement, and what would you recommend? Explain your reasoning.
Antwort:
Begründung:
See The answer in Explanation part below.
Explanation:
Step 1 - Recognise this as a legitimate scoping methodology disagreement, not a problem to paper over.
Both stakeholders are raising genuinely valid, well-established scoping approaches (objectives-based/flag- based versus crown-jewels/asset-based, both discussed in the syllabus), and both have legitimate underlying business drivers - realistic adversary emulation toward a genuinely damaging objective, versus a board- driven need for explicit assurance coverage across named critical systems. Your role is not to simply pick a side, but to facilitate the Control Group toward a well-reasoned, resourced, and realistic decision.
Step 2 - Make the resourcing constraint explicit and central to the discussion. The most important immediate contribution you can make is to be transparent, per the syllabus principle on budget/scope/objective mismatches, that the currently agreed resourcing genuinely cannot deliver both approaches to a proper, credible standard within the available window - attempting to do so would likely mean shallow, unconvincing coverage of seven systems and an under-resourced, unrealistic attempt at the funds-transfer objective, satisfying neither stakeholder's actual underlying need well. Surfacing this constraint honestly and early is essential before any scope decision is finalised.
Step 3 - Explore whether the two preferences are more reconcilable than they first appear. Rather than treating this as strictly either/or, explore with the Control Group whether a hybrid, prioritised approach could serve both underlying needs: for example, a primary, well-resourced objectives-based scenario targeting unauthorised funds transfer capability (satisfying the realistic-adversary-emulation goal), where the realistic attack paths pursued are deliberately chosen, where feasible, to pass through or touch several of the seven named critical systems along the way - meaning the Head of Operational Resilience's board reporting could legitimately describe those touched systems as having been genuinely, realistically assessed as part of an integrated scenario, even though not every one of the seven was necessarily reached, while remaining honest that the coverage was realistic-path-driven rather than an independent, systematic per-system assessment for every listed system.
Step 4 - Be explicit about what a compromise honestly does and does not deliver. If a hybrid approach is pursued, you must be scrupulously honest with the Control Group that this does not equate to full, independent assurance coverage of all seven systems in the way the Head of Operational Resilience originally wanted - some named systems may end up not meaningfully touched at all if the realistic attack path simply does not lead there, and this must be clearly flagged as an accepted limitation of the chosen approach, not glossed over, so the board's own understanding (via the Head of Operational Resilience) is accurate rather than inadvertently overstated.
Step 5 - Present genuine options to the Control Group rather than deciding for them. Ultimately, this is a Control Group risk and priorities decision, not one for you to make unilaterally. You should present the Control Group with clearly articulated options - for example: (a) a primarily objectives-based scenario as described in Step 3, with honest limitations on per-system coverage; (b) a purely crown-jewels approach systematically but perhaps more superficially covering all seven systems, sacrificing depth and realistic attacker-path continuity; or (c) if the Control Group genuinely believes both are essential and cannot be compromised on, a transparent conversation about whether additional budget/timeline could be sought (echoing the scoping domain's guidance on addressing genuine budget/objective mismatches transparently) - and facilitate a decision, rather than imposing your own preference.
Step 6 - Ensure the final decision and its rationale are properly documented. Whatever the Control Group decides, the choice and its explicit rationale (including the honestly acknowledged trade-offs) should be documented clearly in the scope specification, both so future audit/attestation review understands the reasoning, and so there is a clear record protecting against later disagreement about what was actually promised and delivered.
Conclusion: The correct facilitation approach surfaces the genuine resourcing constraint honestly, explores a hybrid approach that may reasonably serve both stakeholders' underlying needs without pretending it delivers everything either wanted in full, and ultimately presents clear, honest options to the Control Group for their own risk-based decision - rather than the Red Team Manager unilaterally picking one stakeholder's preferred methodology over the other's.

17. Frage
Background: You are scoping a red team engagement for Kestrel Logistics Group, a large freight and warehousing company that has approached your firm directly (this is a voluntary, non-regulator-mandated engagement). During scoping workshops, Kestrel's IT Director is enthusiastic about maximum realism and requests that scope include the warehouse automation systems that control robotic pallet-moving equipment on the floor of their largest distribution centre, arguing "if an attacker could get in there, we need to know - plus it would make a great case study for our board." The systems in question are programmable logic controllers (PLCs) connected to a segregated operational technology (OT) network, with direct physical safety interlocks but a known history of the interlocks occasionally being manually overridden by floor staff during high-volume periods.
Separately, Kestrel's Head of HR asks whether the engagement's planned phishing simulation could specifically target "the three employees currently under a formal performance improvement plan in the finance team, since if they fall for it, it'll help build the case for their upcoming review." Kestrel's budget for the engagement is fixed and was set based on an initial, narrower scope discussion that did not include either the OT environment or an expanded phishing target list.
Question: How should you respond, during scoping, to (a) the request to include the warehouse robotic PLC/OT environment, and (b) the HR request regarding the three employees on a performance improvement plan?
Explain the scoping and ethical principles that should guide your response, and address the budget implication.
Antwort:
Begründung:
See The answer in Explanation part below.
Explanation:
Step 1 - Assess the OT/PLC request against life-safety risk principles. As covered in the scoping domain, systems with genuine life-safety implications require significantly enhanced caution. Here, the PLCs control physical robotic equipment with safety interlocks that are known to be manually overridden during busy periods - meaning the assumed safety margin is already weaker in practice than the engineering design intends. Live, unconstrained red team testing against this environment carries a real, non-trivial risk of triggering unsafe robotic behaviour at a moment when a human safety control may not be reliably in place.
This is precisely the kind of risk-benefit judgement call the syllabus emphasises: enthusiasm for realism does not outweigh a genuine, credible safety risk.
Step 2 - Do not simply accept or flatly refuse; investigate proportionate alternatives. The correct scoping response is not a binary yes/no delivered on the spot, but a structured risk conversation: you should explain the safety concern clearly to the IT Director, and propose involving Kestrel's own engineering/health-and- safety stakeholders (who were not present in this workshop) before any decision is made - consistent with the syllabus principle that OT/life-safety scoping decisions require input beyond IT alone. Proportionate alternatives to discuss could include: testing in a representative non-production/test-bed environment if one exists; a narrowly scoped, closely supervised assessment focused on the IT/OT boundary (e.g., segmentation controls) rather than live interaction with the PLCs themselves; or excluding live technical testing of the PLCs while instead reviewing configuration and architecture documentation to assess exposure without hands-on interaction.
Step 3 - Do not let "board case study" value override the risk assessment. The IT Director's stated motivation (a compelling board case study) is understandable but is not, on its own, a sufficient justification for accepting elevated safety risk - this is exactly the kind of scenario where a Red Team Manager must exercise independent professional judgement rather than simply satisfying an enthusiastic client stakeholder's preference.
Step 4 - Assess the HR request against fairness, proportionality, and data protection/employment principles.
Deliberately targeting three specific, named individuals who are already on a formal performance improvement plan, for the specific purpose of contributing to their performance review outcome, is a serious ethical and fairness problem. Simulated phishing exercises exist to assess and improve organisational security awareness and controls, not to be repurposed as a covert input into individual disciplinary or performance management processes against specific, already-vulnerable staff. This also raises genuine data protection and, depending on jurisdiction, employment law concerns (as discussed in the legal considerations domain regarding employee monitoring/testing), since using engagement data this way was not the stated, transparent purpose of the exercise and could constitute unfair or incompatible processing of personal data relating to those individuals.
Step 5 - Decline the HR request clearly, and explain why. You should decline this request professionally but firmly, explaining that simulated phishing must be designed and used for legitimate organisational security improvement purposes, applied consistently (for example, across a representative sample or the whole relevant population) rather than to covertly target specific named individuals for a disciplinary purpose, and that using it this way would be inappropriate, potentially unlawful, and would undermine trust in the security awareness programme generally if it became known. You should offer an appropriate alternative: a properly designed phishing simulation covering the finance team (or a representative sample of the organisation) as a whole, with aggregated, appropriately anonymised reporting used to inform organisation-wide awareness training - not individual disciplinary outcomes.
Step 6 - Address the budget implication transparently. Both the OT/PLC consideration (which may require additional stakeholder engagement time and possibly a different testing approach) and any legitimate broadening of the phishing scope have resourcing implications beyond the original, narrower budget assumption. Consistent with the scoping domain's guidance on budget/scope/objective mismatches, you should raise this transparently with Kestrel: rather than silently absorbing the extra scope within a fixed budget (risking rushed, lower-quality delivery) or simply refusing to discuss it further, present the client with clear options - an adjusted budget or timeline to properly and safely accommodate a reasonable OT- boundary assessment, or confirmation that OT remains out of scope for this engagement given budget constraints, with the safety-driven rationale documented either way.
Conclusion: The OT/PLC request requires a proportionate, safety-led scoping conversation involving the right stakeholders, likely resulting in a scaled-back or alternative approach rather than full live testing given the known interlock override risk; the HR request should be declined on ethical, fairness, and data protection grounds, with a legitimate alternative offered; and both scope changes should be reconciled transparently against the fixed budget rather than absorbed silently.

18. Frage
Background: You are the Control Team Lead's primary point of contact at the Red Team provider for a TIBER-EU engagement against Larchmont Insurance SE. In week 9 of the required 12-week active Red Team testing phase, your team achieves the agreed primary objective (demonstrating a realistic path to manipulating claims-payment data) far earlier than the original plan anticipated, and does so without being detected by the Blue Team at any point. Your lead tester messages you, enthusiastic, suggesting that since the objective is already achieved with three weeks of the mandated minimum window still remaining, the team should simply
"wrap up early, write the report now, and free up the team for other engagements," since "we've proven the point already and nothing important is likely to change in the remaining weeks." Separately, the Threat Intelligence Report identified a secondary, lower-probability but still plausible threat actor and attack path (targeting the SE entity's cross-border reinsurance data-sharing arrangements) that the original test plan had allocated the remaining weeks to explore, time permitting.
Question: Assess the lead tester's suggestion to conclude testing early, and explain what should actually happen with the remaining three weeks of the mandated testing window.
Antwort:
Begründung:
See The answer in Explanation part below.
Explanation:
Step 1 - Recognise why the suggestion, though understandable, is methodologically incorrect. The lead tester's enthusiasm is understandable - achieving the primary objective undetected is a genuinely strong result - but the suggestion to end active testing three weeks early conflicts directly with TIBER-EU's minimum 12-week active testing guidance, which exists, as covered in the syllabus, for substantive methodological reasons (allowing realistic, patient adversary emulation and providing a genuine, sustained test of detection capability over a realistic timeframe), not merely as an arbitrary box to tick once any single objective is achieved.
Step 2 - Reject the "we've proven the point already" framing. Early achievement of the primary objective does not mean "nothing important is likely to change" - this framing significantly understates the value of the remaining time. As established elsewhere in this syllabus, a well-planned TIBER-EU engagement should have identified secondary, still-plausible attack paths (exactly as this scenario describes, with the cross-border reinsurance data-sharing scenario) precisely so that remaining time can be used productively rather than the exercise simply stopping once one objective is reached.
Step 3 - Do not unilaterally decide to end testing early. As Red Team provider lead contact, you should not agree to end active testing early based on your lead tester's operational preference (however reasonably intentioned, including the genuine desire to free up the team for other work) without this being a decision made transparently with the Control Team and, given TIBER-EU's minimum-duration guidance, very likely requiring at least awareness of the national TIBER Cyber Team, consistent with the syllabus principle that material deviations from framework timing guidance should not be decided informally by the delivery team alone.
Step 4 - Recommend pivoting to the secondary threat actor/attack path for the remaining weeks. The professionally sound recommendation is to use the remaining three mandated weeks productively by pivoting to explore the secondary, still-plausible threat actor and attack path (the cross-border reinsurance data-sharing scenario) that the original plan had specifically reserved time for - this makes full, valuable use of the mandated window, provides Larchmont with meaningfully broader insight beyond the single already-proven objective, and respects the framework's minimum-duration guidance in substance, not just in form.
Step 5 - Address the resourcing tension honestly rather than ignoring it. The lead tester's underlying point about wanting to free up the team for other engagements reflects a genuine resourcing/capacity consideration (echoing the concurrent-engagement management principle discussed elsewhere in this practice set), and this should not simply be dismissed - but the correct response is to raise this transparently with your own firm's resourcing/practice management function as a separate capacity planning conversation, rather than allowing it to unilaterally drive premature conclusion of a live, regulator-relevant engagement that has mandated timing requirements.
Step 6 - Communicate transparently with the Control Team about the strong early result and the plan for the remaining time. You should proactively inform the Control Team of the strong, undetected achievement of the primary objective (itself a significant, positive finding worth flagging promptly, consistent with the reporting domain's guidance on timely communication of significant developments) and explain the plan to use the remaining mandated weeks to explore the secondary, still-plausible scenario - giving the Control Team full visibility and the opportunity to input on or endorse this plan, rather than either silently continuing without explanation or silently stopping early without their knowledge.
Step 7 - Consider whether the strong result also has an earlier learning opportunity, without ending testing.
While full closure/purple-teaming should still occur only at the properly planned end of the Testing phase, you might also confirm with the Control Team whether they wish to be given a preliminary, high-level heads- up about the strength of the primary result now (while continuing testing on the secondary path) - a judgement call to be made collaboratively with the Control Team, balancing their interest in early insight against maintaining full engagement momentum and Blue Team blindness through to the properly planned closure point.
Conclusion: The lead tester's suggestion to end active testing three weeks early should not be accepted; the mandated minimum testing window should be used productively by pivoting to the secondary, still-plausible threat actor and attack path the original plan reserved time for, with this plan communicated transparently to the Control Team; and any genuine resourcing/capacity tension underlying the tester's suggestion should be addressed separately through the provider's own internal capacity management, not by cutting short a live, framework-governed engagement.

19. Frage
Background: You lead the threat intelligence workstream for an intelligence-led engagement against Thornbury Energy Supply, a mid-sized UK energy retailer voluntarily commissioning STAR-FS-aligned testing. Two of your open-source intelligence sources - a well-regarded commercial threat intelligence feed (historically rated highly reliable) and a smaller, independent security researcher's blog (previously unrated by your team, but sometimes cited by others in the industry) - offer conflicting characterisations of the most plausible threat actor. The commercial feed assesses that Thornbury's sector is currently most targeted by a financially motivated group using commodity ransomware delivered via exposed RDP and unpatched VPN appliances. The independent blog, in a recent post, claims - citing an anonymous source it does not name - that a specific, more sophisticated actor group is "actively targeting UK mid-sized energy retailers specifically" using a novel technique involving compromised smart-metering data platforms, though no other source you can find corroborates this specific claim.
Your junior analyst is enthusiastic about the independent blog's claim, arguing "it's much more interesting and specific to energy, and the smart-metering angle would make for a really compelling, novel scenario for the client." Separately, the engagement's fixed timeline only allows for one primary scenario to be developed in the time available.
Question: Explain how you would assess and reconcile these conflicting sources, and justify which scenario direction you would ultimately recommend, addressing the analytical principles involved.
Antwort:
Begründung:
See The answer in Explanation part below.
Explanation:
Step 1 - Apply structured source reliability and information credibility assessment. Consistent with the Admiralty/NATO-style analytical discipline covered in the syllabus, the two sources should not be treated as equally weighted simply because both are available. The commercial feed has a demonstrated track record of reliability; the independent blog is unrated by your own team and, critically, its specific claim rests on a single anonymous, unnamed source with no independent corroboration you have been able to find elsewhere. On these facts, the commercial feed's assessment currently carries materially higher source reliability and information credibility.
Step 2 - Explicitly name and manage the analytical bias risk your junior analyst is displaying. The junior analyst's enthusiasm for the blog's claim appears to be driven by its novelty and narrative appeal ("more interesting," "compelling, novel scenario") rather than by its evidential strength - this is a textbook illustration of the confirmation-bias and narrative-appeal risk discussed in the syllabus, where analysts can be drawn toward a more exciting conclusion that is not actually the best-supported one. As the workstream lead, you should directly and constructively address this with the analyst, using it as a teaching moment about separating "interesting" from "well-evidenced." Step 3 - Attempt further corroboration before dismissing either source outright. Good analytical practice is not to simply discard the blog's claim because it is currently uncorroborated, but to make a proportionate, time-boxed effort to seek further corroboration (e.g., checking whether any other reputable source, sector information-sharing body, or your commercial feed provider itself has any related reporting on smart- metering platform compromise activity), before reaching a final judgement - since dismissing a source too readily is itself a form of analytical bias.
Step 4 - Reach and clearly articulate an evidence-based judgement. Assuming no further corroboration for the blog's specific claim emerges within a reasonable, proportionate effort, the analytically sound conclusion is that the commercial feed's assessment (financially motivated actor, commodity ransomware via exposed RDP/VPN) currently represents the better-supported, more plausible basis for scenario design, given its stronger source reliability and the absence of corroboration for the competing claim - not because it is a
"safer" or more conventional choice, but because it is the conclusion the actual evidence currently supports.
Step 5 - Do not entirely discard the blog's claim; handle it proportionately. Rather than ignoring the smart- metering claim altogether, good practice is to document it explicitly as a lower-confidence, uncorroborated possibility worth continued monitoring (potentially revisited if the engagement timeline allows a secondary, smaller-scale element, or flagged for the client's own ongoing threat-monitoring attention beyond this specific engagement), rather than silently dropping it with no record - this preserves analytical transparency about what was considered and why it was not selected as the primary scenario basis.
Step 6 - Justify the final scenario recommendation on evidential, not narrative, grounds. Your recommendation to develop the primary scenario around the commercially-sourced, better-evidenced threat actor should be explicitly justified to the client/Control Group on the basis of source reliability and corroboration - genuinely explaining why the more mundane-sounding scenario is, in this instance, the analytically correct choice, precisely so that the eventual Red Team exercise tests a plausible, evidence-based threat rather than an intriguing but currently unsubstantiated one, consistent with the core intelligence-led testing principle running throughout this syllabus.
Step 7 - Use this as a wider training point. Beyond this specific engagement, this scenario is a valuable illustration for the analyst (and the wider team) of the discipline required in threat intelligence work: resisting the pull toward the most narratively compelling conclusion, applying structured reliability/credibility assessment consistently, and being willing to recommend the "less exciting" but better-evidenced scenario when that is what rigorous analysis actually supports.
Conclusion: The commercial feed's assessment should be preferred as the primary scenario basis given its materially stronger source reliability and the absence of corroboration for the independent blog's claim; the junior analyst's narrative-driven preference should be addressed directly as a bias-management teaching point; and the uncorroborated claim should be documented transparently as a lower-confidence possibility rather than silently discarded, preserving full analytical transparency.

20. Frage
Background: You manage a red team engagement for Brackenfell Retail Group under an RoE that explicitly permits "controlled, non-destructive proof-of-concept payload execution to demonstrate exploitation of identified vulnerabilities" but explicitly prohibits "any activity resulting in encryption, deletion, or exfiltration of production data." During week 5, your team successfully exploits a vulnerability in an internal file server and, to demonstrate impact, executes a small proof-of-concept script that creates a single new, clearly labelled test file ("REDTEAM-POC-DO-NOT-DELETE.txt") containing only benign placeholder text, then takes a screenshot as evidence, and immediately deletes the test file it created.
A junior tester on the team, reviewing this activity in the daily standup, raises a question: "Doesn't creating and then deleting a file, even one we created ourselves, technically fall under 'deletion... of production data,' since it was on a production file server?" Separately, that same day, a different, more senior tester proposes going further on a different system: rather than just creating a placeholder file, they suggest locating one genuinely low-value, clearly non-critical existing file (e.g., an old, unused template document) already present on a production file share, and temporarily renaming it (not deleting it) to demonstrate write-access impact more "authentically," planning to rename it back immediately afterward.
Question: Assess whether the actions already taken (creating and deleting the labelled test file) were consistent with the RoE, and explain how you should respond to the senior tester's proposal to rename an existing production file. What broader RoE interpretation principle does this scenario illustrate?
Antwort:
Begründung:
See The answer in Explanation part below.
Explanation:
Step 1 - Analyse the already-completed action against the RoE's actual wording and intent. The RoE prohibits "deletion... of production data," which, read in context alongside the explicit permission for
"controlled, non-destructive proof-of-concept" activity, is clearly intended to protect the client's genuine, pre- existing production data and business operations - not to prohibit a tester deleting a file the tester itself created purely as evidence, containing no genuine client data, and clearly labelled as such. The junior tester's question is a reasonable and valuable prompt for careful interpretation, but on balance this specific action (create clearly labelled benign test artefact, evidence it, then remove it) is consistent with both the letter and the clear underlying intent of the RoE, since no genuine production data was ever placed at risk.
Step 2 - Do not dismiss the junior tester's question - use it constructively. Even though the specific action was likely fine, the question itself reflects exactly the kind of careful, RoE-literate thinking that should be encouraged, not brushed aside. The correct management response is to explicitly walk through the reasoning in Step 1 with the team, confirming the action was appropriate and why, so the team's shared understanding of how to interpret RoE boundaries in similar future situations is reinforced and documented (e.g., in the team's engagement log or internal methodology notes for this engagement).
Step 3 - Analyse the senior tester's proposal separately and much more critically. The proposal to rename an existing, genuine production file - even one assessed by the tester as "low-value" and even with an intention to rename it back - is materially different from Step 1's scenario, because it involves manipulating a real, pre- existing piece of the client's actual data/file estate, however minor the tester judges it to be. This risks falling within the spirit, and arguably the letter, of "activity resulting in... deletion... of production data" (a rename that fails to be reversed for any reason, however unlikely, would functionally be indistinguishable from the original file being lost) and certainly could be seen as testing the boundary of "non-destructive" in a way the RoE was not clearly drafted to authorise.
Step 4 - Reject the proposal, or at minimum, escalate before proceeding. You should not approve the senior tester's proposal to proceed on the strength of the tester's own personal judgement about the file's low value - this is precisely the kind of individually judged, unilateral scope interpretation the syllabus warns against, since "low value" is a business/data-ownership judgement the client, not the tester, is actually positioned to make. If the team genuinely believes this kind of demonstration would add meaningful additional value over the already-completed placeholder-file approach, the correct process is to raise it explicitly with the Control Group/Control Team for an explicit decision (potentially resulting in a documented, narrow RoE clarification or amendment permitting a specifically defined, client-nominated test file to be used this way) - not to proceed based on the tester's own on-the-spot assessment of an existing file's importance.
Step 5 - Extract the broader RoE interpretation principle. This scenario illustrates that RoE interpretation requires reading specific clauses in light of their underlying purpose and risk rationale, not applying either an overly literal reading that would forbid entirely safe, client-protective evidence practices (Step 1), or an overly permissive reading that stretches a "non-destructive" allowance to cover manipulation of genuine, real client data based on an individual tester's own risk judgement (Step 3-4). Ambiguous or borderline situations - precisely because reasonable people can interpret them differently, as this scenario demonstrates - should be resolved through escalation to the accountable governance body, not through unilateral interpretation by whichever tester is at the keyboard at the time, however experienced.
Step 6 - Reinforce this through team practice. As Red Team Manager, you should use this episode as a live training moment: reinforcing to the whole team (not just the two testers involved) that "reversibility intended" is not, on its own, sufficient justification for manipulating genuine client data without escalation, whereas creating and removing entirely tester-generated, clearly labelled artefacts for evidentiary purposes is normally consistent with a well-drafted non-destructive RoE - and that when genuinely unsure, the standing instruction is always to pause and escalate rather than proceed on individual judgement.
Conclusion: The completed placeholder-file action was consistent with the RoE's clear intent and should be confirmed as appropriate; the proposal to rename an existing production file should be declined or, at minimum, escalated to the Control Group/Control Team for an explicit decision rather than proceeding on the tester's own judgement; and the underlying lesson is that RoE boundaries must be interpreted purposively and any genuine ambiguity resolved through escalation, not unilateral, individually judged risk-taking.
