See The answer in Explanation part below.
Explanation:
Step 1 - Recognise this as a direct, high-stakes scope-boundary and safety issue. This is a serious situation: a legitimately in-scope system provides a technical path that could reach an explicitly, emphatically excluded system ("do not interact with under any circumstances") that the client itself believed was already isolated.
Proceeding with full exploitation of the in-scope web application without addressing this discovery first would create a genuine, material risk of inadvertently affecting the excluded fragile legacy system - precisely the outcome the exclusion was designed to prevent.
Step 2 - Pause before proceeding further on this specific path. Consistent with the syllabus principle on discovering unplanned pivot paths toward out-of-scope systems, your team should pause any further exploitation activity on the in-scope web application that could plausibly reach the shared backend database, rather than proceeding on the basis that the web application itself is technically in scope - the relevant risk here is the downstream reachability of the excluded system, not merely the starting point's scope status.
Step 3 - Escalate immediately and clearly to the Control Group. This discovery must be escalated promptly and clearly to the Control Group, explaining precisely what has been found: that the excluded legacy system is not, in fact, isolated as previously believed, and that a legitimately in-scope system provides a plausible technical path to it. This is exactly the kind of significant, safety-relevant scope discovery that requires an explicit Control Group risk decision before any further related activity proceeds, consistent with the syllabus's repeated emphasis on escalating rather than unilaterally resolving scope-boundary ambiguities, especially ones with genuine safety/fragility implications.
Step 4 - Present the Control Group with realistic options, not just a problem. You should help the Control Group understand the realistic options: (a) proceeding with carefully scoped, closely controlled activity that demonstrates the reachability risk without actually interacting with the excluded system's own data or functionality (e.g., demonstrating database-level access is achievable in principle, using a proof-of-concept approach analogous to the "create and remove a labelled test artefact" principle discussed elsewhere in this practice set, without ever querying or touching the legacy system's actual tables/data) - an approach that could deliver highly valuable risk insight while respecting the spirit of the exclusion; (b) excluding further technical demonstration of this specific path altogether and instead documenting the newly discovered reachability as a critical, urgent finding in its own right, given its significance; or (c) if the Control Group wishes to genuinely understand the full extent of exposure, formally and explicitly amending the exclusion (with appropriate additional risk controls and stakeholder sign-off, given the legacy system's described fragility) to permit carefully controlled, limited investigation - a significant decision that should not be made lightly or without input from whoever owns/understands the fragile legacy system best.
Step 5 - Treat the discovery itself as an urgent, high-value finding regardless of what testing path is chosen.
Independently of how (or whether) further technical demonstration proceeds, the fact that the client's own assumption about system isolation was incorrect is itself an extremely significant finding that should be communicated to the Control Group with urgency, given its potential relevance well beyond this engagement (e.g., to the client's own ongoing operational risk management, patching, and architecture decisions) - this is exactly the kind of urgent, severe finding that, per the reporting domain, should be escalated promptly rather than held until the final report.
Step 6 - Reflect on what this reveals about the client's own environment understanding, and note it explicitly. This discovery reveals a genuine, material gap between the client's assumed architecture (systems fully separated) and its actual, current-state architecture (a partially completed migration leaving a shared backend) - a gap the client's own IT team was unaware of until your team's reconnaissance surfaced it. This is valuable, standalone insight for the client about the reliability of its own architecture documentation and change-management assurance processes, and should be explicitly reflected in your reporting/closure commentary as a broader lesson, not just narrowly treated as a scoping technicality to be resolved and then forgotten.
Step 7 - Document the whole episode thoroughly. The discovery, the escalation, the Control Group's decision, and the rationale should all be clearly and contemporaneously documented, both to protect the integrity of the engagement's record and because this kind of significant, safety-relevant scope discovery is precisely the sort of event most likely to be scrutinised later if any question about the engagement's conduct ever arose.
Conclusion: Further exploitation activity on the path toward the excluded legacy system should pause immediately upon discovery, with prompt escalation to the Control Group presenting realistic options ranging from carefully controlled, non-intrusive demonstration to full exclusion of further technical activity on that path; the discovery itself should be treated and escalated as an urgent, high-value finding in its own right; and the episode should be explicitly used to highlight, in reporting, the client's own gap between assumed and actual system architecture as a valuable standalone lesson.

Correct Answer:

See The answer in Explanation part below.
Explanation:
Step 1 - Recognise the shared-facility authorisation problem. The data centre facility itself, and the general access points, common areas, and physical security controls governing entry to the building, are owned and operated by the data centre operator - a separate legal entity - not by Silverpeak. Silverpeak's authorisation can validly cover its own locked cage and the equipment within it, but it cannot validly authorise a physical intrusion attempt against the building's general access controls, which are the data centre operator's own infrastructure and responsibility, exactly analogous to the cloud/SaaS/telecommunications-provider authorisation-boundary issue addressed elsewhere in this syllabus, now applied to a physical rather than purely technical context.
Step 2 - Recognise the additional multi-tenant risk dimension. Beyond the pure authorisation question, a physical intrusion attempt against the shared facility risks affecting or alarming the other two unrelated Authorized Institutions whose cages are in immediate physical proximity - for example, if the attempt triggers a wider facility security response, lockdown, or law enforcement involvement affecting the whole building, not just Silverpeak's area. This mirrors the "shared multi-tenant environment" risk principle covered elsewhere in this syllabus regarding cloud infrastructure, now applied physically, and materially raises the stakes of proceeding without the operator's explicit involvement.
Step 3 - Do not proceed with the physical facility-entry component as currently framed. Given Steps 1 and
2, this specific element should not proceed on the basis of Silverpeak's authorisation alone. The professionally correct response to the Control Group is to explain clearly why their own authorisation cannot legally or safely extend to testing the shared building's general access controls, however enthusiastic they are about a comprehensive test.
Step 4 - Identify legitimate alternative approaches. Rather than simply declining outright, you should discuss constructive alternatives with the Control Group: (i) engaging the data centre operator directly to seek their explicit, separate consent for a properly scoped and coordinated physical test of the building's general access controls (which, if obtained, would need to be documented and would still require care given the other tenants' interests, potentially requiring their awareness or at least the operator's confirmation that testing is compatible with its own obligations to other tenants); (ii) narrowing the physical testing component to elements genuinely within Silverpeak's own control, such as testing access controls on Silverpeak's own locked cage itself (e.g., attempting to gain entry to the cage assuming a tester has already reached the general shared area through legitimate means, or testing whether Silverpeak's own escort/visitor procedures are followed by data centre staff who do have authorised access) - carefully scoped to avoid implicating the operator's own general building security; or (iii) excluding physical facility testing from this engagement and instead documenting physical access risk at the shared facility as a topic for Silverpeak's own vendor/facilities risk management and direct conversation with the data centre operator outside the iCAST engagement itself.
Step 5 - Address the legal-position concern rigorously, not informally. The team member's instinct that Hong Kong's legal position may differ from a "UK-only" assumption is exactly correct as a concern, and it should not be left informally unresolved. Consistent with the syllabus principle on jurisdiction-specific legal risk, your firm should not proceed with any physical social engineering element in Hong Kong based on assumptions carried over from UK engagements. This requires confirming (through your firm's own established Hong Kong legal understanding, given this is an iCAST-accredited engagement where such understanding should already exist, or through specific local legal advice if any doubt remains) the local legal position on trespass and physical intrusion testing, and ensuring the authorisation and RoE documentation for this specific engagement explicitly and correctly reflect that position, rather than being inherited unreviewed from unrelated prior UK engagements.
Step 6 - Document the resolution and rationale. Whatever combination of Steps 4's alternatives is ultimately agreed with the Control Group, the rationale, the authorisation boundary reasoning, and the confirmed legal position should be clearly documented in the engagement's scope and RoE documentation, both for internal audit trail purposes and to support any eventual C-RAF/HKMA-related review of the engagement's conduct.
Conclusion: The shared data centre's general building access controls cannot be validly authorised for testing by Silverpeak alone and should not be included without the data centre operator's own explicit, separately obtained consent, given both the authorisation-boundary principle and the added risk to unrelated co-tenants; and the team's informal, unverified assumption about Hong Kong's legal position must be properly and specifically confirmed (not carried over from UK experience) before any physical social engineering proceeds.
