Question 1110
An evidence-led review starts with the following report: A smart thermostat gateway sends traffic to an unknown cloud endpoint after an unapproved firmware update. What investigation should establish the disputed activity and its timeline?
- Compare firmware version and signature with vendor release records and flow logs
- Correlate gateway crash logs, source flows and management parser errors
- Require signed firmware and approved update management for IoT assets
- Restrict the gateway's outbound paths without interrupting essential building control
Explanation
Correct Answer
A:An unexpected firmware build can change device behavior and external communication; the objective is to establish whether firmware integrity or destination was altered; the result can then guide the later protective decision.
Incorrect Answers
B:Timing and input patterns can link traffic to service instability; this serves whether malicious management requests cause availability loss, whereas the requested result is evidence validation involving whether firmware integrity or destination was altered.
C:Firmware provenance reduces supply-chain and unauthorized changes; the requirement concerns whether firmware integrity or destination was altered, so prevention is not incident verification.
D:Network containment protects safety and availability; the goal is evidence validation for whether firmware integrity or destination was altered. Immediate protection does not substantiate findings.
Question 1111
The recurrence-prevention decision is based on this report: Hundreds of identical smart meters share the same embedded administrative secret. What measure strengthens readiness against the observed event?
- Restrict administrative network reachability while planning credential changes
- Inventory firmware identities and validate the shared credential design
- Enforce unique device credentials and isolated management networks
- Rotate credentials through supported provisioning or replace unfixable devices
- Require per-device credentials and secure provisioning contracts
Explanation
Correct Answer
E:Fleet identity design prevents single-secret compromise; a periodic review of this safeguard can track the risk described by whether common embedded credentials amplify compromise.
Incorrect Answers
A:Segment-level containment reduces fleet-wide abuse; the requirement concerns whether common embedded credentials amplify compromise, so one-time protection is not durable prevention.
B:One leaked secret could enable access to many devices; the goal is recurrence prevention for whether common embedded credentials amplify compromise. An investigation is not recurrence prevention.
C:IoT devices should not depend on factory defaults; it is meant to address whether weak device identity enabled unauthorized access, not recurrence prevention for whether common embedded credentials amplify compromise.
D:Recovery needs unique trust per asset where possible; the case needs recurrence prevention addressing whether common embedded credentials amplify compromise; case recovery is not future-risk control.
Question 1112
A long-term control assessment uses this recent event: A mobile device enrolled for company access has developer debugging enabled and is connected to an untrusted kiosk. Which change provides measurable prevention rather than an emergency workaround?
- Enforce managed developer-setting restrictions on high-risk devices
- Require device integrity attestation for sensitive mobile access
- Inspect debugging state, trusted host authorizations and USB connection history
- Disable debugging and sever trust with the unapproved host
- Assess data access and re-enroll or rebuild the device if integrity is uncertain
Explanation
Correct Answer
A:Policy limits unauthorized debugging connections; the control owner can test whether this reduces repeat conditions affecting whether debugging exposes the managed device.
Incorrect Answers
B:Conditional access limits compromised or unmanaged platforms; it is meant to address whether platform integrity meets access policy, not recurrence prevention for whether debugging exposes the managed device.
C:An authorized debug bridge can expose device data or command control; the case needs recurrence prevention addressing whether debugging exposes the managed device; an investigation is not recurrence prevention.
D:Containment closes a physical access channel; when judging whether debugging exposes the managed device, one-time protection is not durable prevention; this is instead initial containment or preservation.
E:Recovery verifies that an external host did not alter the mobile environment; for whether debugging exposes the managed device, case recovery is not future-risk control; recurrence prevention remains necessary.
Question 1113
The team needs temporary protection and must retain evidence. The observed event is: A managed phone is reported stolen while corporate email remains synchronized and device state is uncertain. Investigators need both a defensible factual finding and a limited immediate safeguard. Which TWO actions jointly satisfy those requirements? (Choose TWO.)
- Reprovision on a verified supported device and review exposed sessions
- Enforce screen lock, encryption and rapid lost-device reporting
- Rotate relevant credentials and re-enroll a replacement under policy
- Issue an authorized remote lock or wipe as policy permits and revoke sessions
- Check MDM check-in status, disk encryption and recent mail sessions
Explanation
Correct Answers
D:Identity and device controls complement each other for offline devices; within the combined response for whether a lost mobile device can access enterprise mail, this supplies initial containment or preservation: this is a first-response safeguard for whether a lost mobile device can access enterprise mail, not a substitute for full root-cause analysis.
E:Remote management and account logs reveal remaining access risk; within the combined response for whether a lost mobile device can access enterprise mail, this supplies evidence validation: it makes the determination of whether a lost mobile device can access enterprise mail defensible and reviewable by the incident owner.
Incorrect Answers
A:Trust restoration requires an approved system state; the activity targets whether platform integrity meets access policy; initial containment or preservation here concerns whether a lost mobile device can access enterprise mail.
B:Baseline controls reduce physical-loss exposure; when judging whether a lost mobile device can access enterprise mail, prevention cannot replace immediate action; this is instead recurrence prevention.
C:Restoring safe mobility requires verified device identity; for whether a lost mobile device can access enterprise mail, corrective follow-through follows initial protection; initial containment or preservation remains necessary.
Question 1114
During lessons learned, the security owner reviews this completed incident: A retail branch uses unmanaged point-of-sale terminals with no inventory or device-level response contacts. Which repeatable safeguard best prevents this failure mode in the future?
- Maintain endpoint inventory and risk-based monitoring for business appliances
- Build approved reimage and transaction-reconciliation procedures with the vendor
- Use offline-capable controls and reconnect compliance checks
- Reconcile branch asset lists, software support and management ownership
Explanation
Correct Answer
A:Visibility makes incident preparation possible; the assurance measure is designed around whether endpoint scope includes specialized business devices, rather than hiding the reported activity.
Incorrect Answers
B:Recovery must preserve financial accuracy and supported configurations; when judging whether endpoint scope includes specialized business devices, case recovery is not future-risk control; this is instead trusted restoration.
C:Remote endpoints need protection between central connections; the other incident centers on whether intermittent devices retain protective coverage, not this recurrence prevention question about whether endpoint scope includes specialized business devices.
D:Untracked terminals hinder coordinated detection and vendor-assisted restoration; the requirement concerns whether endpoint scope includes specialized business devices, so an investigation is not recurrence prevention.
Question 1115
Following initial stabilization, the team must prove recovery for this case: An organization treats a mobile device alert as irrelevant because all central servers are fully patched. Which correction must be verified before the affected service or process is restored?
- Include managed mobile clients in detection and response coverage
- Build approved reimage and transaction-reconciliation procedures with the vendor
- Revalidate device trust and account sessions before restoring application access
- Restrict the suspect device's access to corporate resources
Explanation
Correct Answer
C:Recovery must include client integrity and identity state; the owner can validate the correction against the evidence bearing on whether endpoints can bypass server-centric protection.
Incorrect Answers
A:Protection must follow enterprise data to endpoints; the case needs trusted restoration addressing whether endpoints can bypass server-centric protection; future hardening is not current-state recovery.
B:Recovery must preserve financial accuracy and supported configurations; this serves whether endpoint scope includes specialized business devices, whereas the requested result is trusted restoration involving whether endpoints can bypass server-centric protection.
D:Endpoint containment stops further use of exposed sessions; the requirement concerns whether endpoints can bypass server-centric protection, so temporary protection does not complete correction.
Question 1116
A technical closure review begins after this incident: A warehouse IoT gateway is repeatedly rebooting after malformed management traffic from an unknown segment. After the immediate situation is stabilized, what addresses the enabling failure?
- Update supported firmware and validate stable gateway communication
- Restore vendor-verified firmware and validate operating parameters
- Filter unauthorized management traffic at the segment boundary
- Segment device management and patch vulnerable network services
Explanation
Correct Answer
A:Recovery should remove the exposed fault condition; the affected workflow should not be considered trusted until the issue of whether malicious management requests cause availability loss is resolved.
Incorrect Answers
B:Recovery should use supported update mechanisms; the activity targets whether firmware integrity or destination was altered; trusted restoration here concerns whether malicious management requests cause availability loss.
C:Containment avoids repeatedly rebooting the gateway as the only response; when judging whether malicious management requests cause availability loss, temporary protection does not complete correction; this is instead initial containment or preservation.
D:Reduced reachability limits exploitation; for whether malicious management requests cause availability loss, future hardening is not current-state recovery; trusted restoration remains necessary.
Question 1117
The recovery owner is reviewing the underlying failure in this report: A mobile app installed from an unofficial store requests accessibility permissions and begins reading banking notifications. What action most directly repairs the affected access, evidence or system state?
- Disable the suspicious app and restrict sensitive mobile sessions
- Control app installation sources and monitor high-risk permission grants
- Remove the app through managed procedures and assess exposed accounts
- Re-establish trusted configuration and inspect for possible intercepted accounts
Explanation
Correct Answer
C:Recovery includes the information the app may have observed; this goes beyond temporary protection and addresses the failure identified through whether abuse of accessibility services is occurring.
Incorrect Answers
A:Containment prevents continued observation of protected notifications; the case needs trusted restoration addressing whether abuse of accessibility services is occurring; temporary protection does not complete correction.
B:Permission governance reduces mobile spyware exposure; when judging whether abuse of accessibility services is occurring, future hardening is not current-state recovery; this is instead recurrence prevention.
D:Recovery should treat redirected sensitive traffic as a possible disclosure; the relevant condition for that step is whether configuration profiles redirect or intercept traffic, which is not shown for whether abuse of accessibility services is occurring.
Question 1118
An evidence-led review starts with the following report: An endpoint reports repeated failed logons followed by one successful privileged login from an unfamiliar process. What investigation should establish the disputed activity and its timeline?
- Correlate logon success, process origin and subsequent privileged actions
- Detect failed-to-successful login sequences and enforce MFA
- Correlate process access telemetry, privileges and executable provenance
- Revoke the questionable session and restrict the affected account
Explanation
Correct Answer
A:A successful authentication after failures can signal an active compromise; the objective is to establish whether password guessing became successful access; the result can then guide the later protective decision.
Incorrect Answers
B:Contextual authentication analytics improves detection; for whether password guessing became successful access, prevention is not incident verification; evidence validation remains necessary.
C:Unexpected access to the authentication process can indicate credential theft; it is meant to address whether credential dumping was attempted, not evidence validation for whether password guessing became successful access.
D:Identity containment limits use of the newly gained access; the goal is evidence validation for whether password guessing became successful access. Immediate protection does not substantiate findings.
Question 1119
Active first response is underway for the following condition: An IoT sensor remains reachable over a legacy Telnet service used only during installation. The incident owner wants a corroborating check and a protective action before recovery begins. Which TWO choices fit these separate tasks? (Choose TWO.)
- Inspect listening services, authentication records and asset configuration
- Require secure-by-default device commissioning checklists
- Disable or firewall Telnet access through approved device controls
- Upgrade supported firmware and validate camera configuration after compromise review
- Update supported firmware and validate stable gateway communication
- Move maintenance to a supported secure management interface and audit access
Explanation
Correct Answers
A:An unused plaintext management protocol increases attack surface; within the combined response for whether an unnecessary remote service exposes device control, this supplies evidence validation: the objective is to establish whether an unnecessary remote service exposes device control; the result can then guide the later protective decision.
C:Service containment limits remote command entry; within the combined response for whether an unnecessary remote service exposes device control, this supplies initial containment or preservation: the immediate response addresses whether an unnecessary remote service exposes device control while the team preserves relevant case records.
Incorrect Answers
B:Hardening at install time prevents dormant weaknesses; prevention cannot replace immediate action in the decision about whether an unnecessary remote service exposes device control.
D:Recovery must address both access and possible persistent settings; it is meant to address whether weak device identity enabled unauthorized access, not initial containment or preservation for whether an unnecessary remote service exposes device control.
E:Recovery should remove the exposed fault condition; the other incident centers on whether malicious management requests cause availability loss, not this initial containment or preservation question about whether an unnecessary remote service exposes device control.
F:Recovery removes the unsafe legacy path; the requirement concerns whether an unnecessary remote service exposes device control, so corrective follow-through follows initial protection.
Question 1120
The team requires traceable proof for an event described as follows: An industrial controller vendor prohibits untested security agents, but the SOC intends to install a standard endpoint scanner during an incident. What should be correlated to determine whether the case finding is justified?
- Maintain OT-specific tool approvals and isolated test environments
- Measure event volume, retention settings and off-host forwarding latency
- Confirm vendor support, process dependencies and authorized maintenance procedures
- Use passive telemetry and coordinate containment with OT engineers
Explanation
Correct Answer
C:Unvalidated software can disrupt controllers and physical operations; it makes the determination of whether the equipment vendor approves the proposed scanner for this controller defensible and reviewable by the incident owner.
Incorrect Answers
A:Preparation avoids dangerous production experiments; when judging whether the equipment vendor approves the proposed scanner for this controller, prevention is not incident verification; this is instead recurrence prevention.
B:Noisy logs can crowd out security events before collection; that method could help with whether security telemetry capacity is adequate; the evidence validation decision here involves whether the equipment vendor approves the proposed scanner for this controller.
D:Safety and operational continuity govern intervention choices; the goal is evidence validation for whether the equipment vendor approves the proposed scanner for this controller. Immediate protection does not substantiate findings.
