ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 87

Question 860

The coordinator needs corrective action rather than another alert. The event was: An attacker disables centralized audit export from a tenant shortly before modifying access policies. Which follow-through step verifies the weakness was removed?

  1. Reconstruct actions from available provider and downstream service logs
  2. Restore protected logging and restrict identities able to alter audit sinks
  3. Inspect audit-export configuration changes and independent sink receipt records
  4. Restore copies from independent protected repositories and reapply retention controls
  5. Use separate security accounts and tamper-resistant log storage

Explanation

Correct Answer

A:

Investigators must mark periods where coverage is incomplete; the affected workflow should not be considered trusted until the issue of whether log tampering obscured follow-on actions is resolved.

Incorrect Answers

B:

Containment protects remaining records and future visibility; temporary protection does not complete correction in the decision about whether log tampering obscured follow-on actions.

C:

Control-plane disablement may create evidence gaps after the change; the case needs trusted restoration addressing whether log tampering obscured follow-on actions; verification is not the corrective step.

D:

Recovery requires trusted data beyond the compromised policy scope; the relevant condition for that step is whether backup immutability was weakened before destructive changes, which is not shown for whether log tampering obscured follow-on actions.

E:

Administrative separation reduces attacker ability to hide traces; for whether log tampering obscured follow-on actions, future hardening is not current-state recovery; trusted restoration remains necessary.

Question 861

The team needs temporary protection and must retain evidence. The observed event is: Cloud investigators do not know whether the incident affects the tenant, provider platform or a managed service. Investigators need both a defensible factual finding and a limited immediate safeguard. Which TWO actions jointly satisfy those requirements? (Choose TWO.)

  1. Document shared-responsibility assignments in cloud incident playbooks
  2. Document customer-owned fixes and provider dependencies before service restoration
  3. Maintain service-specific responsibility matrices and support escalation contacts
  4. Classify compromised identity, customer configuration and provider-managed service components
  5. Open provider support and customer security response channels in parallel as warranted

Explanation

Correct Answers

D:

The responsible party differs by the resource and underlying failure; within the combined response for which responsibility boundary controls remediation, this supplies evidence validation: it makes the determination of which responsibility boundary controls remediation defensible and reviewable by the incident owner.

E:

Coordinated escalation avoids delay at an unclear boundary; within the combined response for which responsibility boundary controls remediation, this supplies initial containment or preservation: this is a first-response safeguard for which responsibility boundary controls remediation, not a substitute for full root-cause analysis.

Incorrect Answers

A:

Clear roles reduce response gaps across service boundaries; this serves which party is responsible for tenant-specific evidence retention, whereas the requested result is initial containment or preservation involving which responsibility boundary controls remediation.

B:

Recovery plans should include both sides' obligations; the goal is initial containment or preservation for which responsibility boundary controls remediation. Corrective follow-through follows initial protection.

C:

Prepared boundaries improve cloud incident coordination; prevention cannot replace immediate action in the decision about which responsibility boundary controls remediation.

Question 862

The incident owner requests a defensible factual determination after hearing: An account breach affects resources in several regions, but investigators search logs only in the default console region. What fact-checking activity tests the observed failure most directly?

  1. Review orchestrator events, centralized logs and image metadata
  2. Use centralized multi-region log aggregation and region inventory
  3. Restrict compromised cross-region identities while preserving logs in every affected scope
  4. Inventory affected regions and query relevant regional and organization-level audit sources

Explanation

Correct Answer

D:

Cloud resources and logging scope can vary by service and region; this evidence is scoped to whether the investigation includes regional activity, not a generic system-health reading.

Incorrect Answers

A:

Ephemeral workloads can disappear before investigators examine their local filesystem; it is meant to address which cloud artifacts outlive short-lived compute instances, not evidence validation for whether the investigation includes regional activity.

B:

Broad visibility reduces geographic investigation blind spots; the requirement concerns whether the investigation includes regional activity, so prevention is not incident verification.

C:

Identity containment must cover all reachable deployments; the goal is evidence validation for whether the investigation includes regional activity. Immediate protection does not substantiate findings.

Question 863

A triage analyst needs to test a report involving these details: An AWS incident begins with unexpected IAM policy attachment to an automation role. Which evidence collection or correlation is most relevant to this claim?

  1. Remove the unauthorized policy and restrict the compromised principal
  2. Search CloudTrail management events for AttachRolePolicy and related identity operations
  3. Alert on sensitive IAM policy attachments and enforce least privilege
  4. Correlate StopLogging events with IAM user-creation activity and downstream archives

Explanation

Correct Answer

B:

IAM configuration changes are control-plane actions recorded by CloudTrail; that evidence directly tests the concern about which AWS audit events explain privilege escalation, rather than relying on a single unverified indicator.

Incorrect Answers

A:

Privilege containment reduces potential follow-on API access; when judging which AWS audit events explain privilege escalation, immediate protection does not substantiate findings; this is instead initial containment or preservation.

C:

High-impact entitlement changes should be monitored; the requirement concerns which AWS audit events explain privilege escalation, so prevention is not incident verification.

D:

Independent logging may preserve evidence of the attempt to suppress telemetry; this serves whether audit tampering preceded unauthorized identities, whereas the requested result is evidence validation involving which AWS audit events explain privilege escalation.

Question 864

To prevent the next similar event, analysts review this case: An Azure container registry shows an unauthorized image pushed under an existing trusted tag. Which preventive change targets the exact pathway that failed?

  1. Enforce policies that disallow unnecessary public blob access
  2. Enforce immutable tags, image signatures and least-privilege registry permissions
  3. Compare registry manifest digests, push audit records and pipeline release history
  4. Suspend deployment of the affected digest and restrict registry write access
  5. Redeploy a signed verified image and inspect workloads that pulled the malicious digest

Explanation

Correct Answer

B:

Artifact integrity controls reduce malicious replacement; it closes a repeatable gap revealed by whether mutable image tags conceal a supply-chain compromise without removing useful monitoring.

Incorrect Answers

A:

Preventive governance catches exposure before release; the other incident centers on whether object exposure resulted from public access settings, not this recurrence prevention question about whether mutable image tags conceal a supply-chain compromise.

C:

A familiar tag can reference a different artifact after a malicious overwrite; an investigation is not recurrence prevention in the decision about whether mutable image tags conceal a supply-chain compromise.

D:

Digest-level containment prevents promotion of the tainted image; the case needs recurrence prevention addressing whether mutable image tags conceal a supply-chain compromise; one-time protection is not durable prevention.

E:

Recovery must account for prior deployment as well as repository state; when judging whether mutable image tags conceal a supply-chain compromise, case recovery is not future-risk control; this is instead trusted restoration.

Question 865

The response team seeks the relevant control point for this problem: A cloud administrator revokes one user's console access but leaves active service tokens for an automation identity exposed. Investigators need both a defensible factual finding and a limited immediate safeguard. Which TWO actions jointly satisfy those requirements? (Choose TWO.)

  1. Reissue scoped workload identities and validate downstream integrations
  2. Inventory machine identities and enforce secret rotation and least privilege
  3. Enumerate API keys, service principals and session use in audit history
  4. Revoke exposed service tokens and restrict their effective roles
  5. Review access history, remove unauthorized changes and rotate exposed credentials

Explanation

Correct Answers

C:

Interactive console access is only one possible authorization route; within the combined response for which identities still allow malicious API actions, this supplies evidence validation: it makes the determination of which identities still allow malicious API actions defensible and reviewable by the incident owner.

D:

Credential-specific containment stops unattended API calls; within the combined response for which identities still allow malicious API actions, this supplies initial containment or preservation: this is a first-response safeguard for which identities still allow malicious API actions, not a substitute for full root-cause analysis.

Incorrect Answers

A:

Recovery should restore automation without returning excessive privilege; when judging which identities still allow malicious API actions, corrective follow-through follows initial protection; this is instead trusted restoration.

B:

Workload credentials need lifecycle controls like human accounts; for which identities still allow malicious API actions, prevention cannot replace immediate action; initial containment or preservation remains necessary.

E:

Closing the port alone cannot undo possible prior logins; the other incident centers on whether cloud network policy introduced internet exposure, not this initial containment or preservation question about which identities still allow malicious API actions.

Question 866

The response record begins with an unresolved observation: A suspicious virtual machine is about to be deleted by an autoscaling group after a failed health check. What documentation or telemetry would most reliably support the incident determination?

  1. Build acquisition hooks into autoscaling and incident runbooks
  2. Snapshot relevant disks and preserve instance metadata before trusted replacement
  3. Compare retention-configuration audit events with deletion timestamps
  4. Identify attached volumes, relevant runtime events and upcoming termination action
  5. Temporarily suspend the implicated termination workflow under incident authority

Explanation

Correct Answer

D:

Ephemeral compute replacement can destroy disk state and local logs; this evidence is scoped to whether termination will erase useful host evidence, not a generic system-health reading.

Incorrect Answers

A:

Automated preservation reduces loss from routine lifecycle events; the case needs evidence validation addressing whether termination will erase useful host evidence; prevention is not incident verification.

B:

Investigation can continue from copies without retaining compromised production machines indefinitely; when judging whether termination will erase useful host evidence, recovery is not factual verification; this is instead trusted restoration.

C:

A settings change can remove a safeguard immediately before data loss; that method could help with whether backup immutability was weakened before destructive changes; the evidence validation decision here involves whether termination will erase useful host evidence.

E:

A controlled hold creates an opportunity for acquisition; the goal is evidence validation for whether termination will erase useful host evidence. Immediate protection does not substantiate findings.

Question 867

The team has retained the initial evidence and is assessing recovery from: An unknown access key downloads large volumes of objects from a cloud storage container. After initial protection, which investigation or follow-through best establishes the remaining scope?

  1. Prefer short-lived workload identity and monitor bulk object reads
  2. Assess accessed object scope and issue replacement credentials to legitimate workloads
  3. Reissue scoped workload identities and validate downstream integrations
  4. Disable or rotate the exposed key and constrain storage access

Explanation

Correct Answer

B:

Recovery must distinguish data disclosure from service restoration; the investigation of whether API credentials were used for unauthorized reads must precede any claim that the affected state has been fully restored.

Incorrect Answers

A:

Reducing static-key use narrows long-term credential risk; when judging whether API credentials were used for unauthorized reads, future hardening is not current-state recovery; this is instead recurrence prevention.

C:

Recovery should restore automation without returning excessive privilege; this serves which identities still allow malicious API actions, whereas the requested result is post-containment assessment involving whether API credentials were used for unauthorized reads.

D:

Stopping credential replay limits continued downloads; the goal is post-containment assessment for whether API credentials were used for unauthorized reads. Temporary protection does not complete correction.

Question 868

A case is escalated for independent verification after this finding: A cloud workload uses a single static administrator credential across deployment scripts and production services. What collection or comparison would validate the reported condition?

  1. Use workload federation or managed identity with least privilege
  2. Migrate workloads to narrowly scoped short-lived identities
  3. Review log repository permissions and independent audit-sink access
  4. Inventory where the credential is stored and recent privileged API use
  5. Revoke exposed keys and limit the attached role's effective permissions

Explanation

Correct Answer

D:

Shared secrets make attribution difficult and rotation disruptive; it makes the determination of whether long-lived privileged keys enlarge compromise scope defensible and reviewable by the incident owner.

Incorrect Answers

A:

Short-duration credentials reduce persistent access risk; for whether long-lived privileged keys enlarge compromise scope, prevention is not incident verification; evidence validation remains necessary.

B:

Replacing shared administrator keys supports secure recovery; the requirement concerns whether long-lived privileged keys enlarge compromise scope, so recovery is not factual verification.

C:

Attacker-controlled accounts can undermine retention and chain of custody; this serves whether evidence storage is isolated from suspect administrators, whereas the requested result is evidence validation involving whether long-lived privileged keys enlarge compromise scope.

E:

Immediate reduction limits unauthorized cloud operations; the case needs evidence validation addressing whether long-lived privileged keys enlarge compromise scope; immediate protection does not substantiate findings.

Question 869

For the next control cycle, the responder supplies this incident history: An AWS access key is used from an unapproved IP to call resource-creation APIs in multiple regions. Which ongoing safeguard should be implemented and tested?

  1. Find unauthorized resources, remove them after evidence capture and reissue scoped credentials
  2. Maintain preapproved isolation groups and forensic snapshot procedures
  3. Query organization-wide CloudTrail events by access key and region
  4. Use temporary credentials and central CloudTrail monitoring
  5. Enable appropriate S3 object data events for high-risk data stores
  6. Deactivate the exposed access key and restrict associated permissions

Explanation

Correct Answer

D:

Short-lived identity reduces replay windows; the ongoing control is targeted at which record reconstructs cross-region API actions, rather than a one-time emergency fix.

Incorrect Answers

A:

Recovery includes cost and persistence cleanup; the goal is recurrence prevention for which record reconstructs cross-region API actions. Case recovery is not future-risk control.

B:

Prepared tooling avoids ad hoc instance termination; this serves how to isolate suspected AWS compute without destroying evidence, whereas the requested result is recurrence prevention involving which record reconstructs cross-region API actions.

C:

API event records can trace principal actions across affected regions; the case needs recurrence prevention addressing which record reconstructs cross-region API actions; an investigation is not recurrence prevention.

E:

Targeted logging strengthens future disclosure investigations; that method could help with why the audit record lacks individual object reads; the recurrence prevention decision here involves which record reconstructs cross-region API actions.

F:

Credential containment prevents new cloud resources from being created; the requirement concerns which record reconstructs cross-region API actions, so one-time protection is not durable prevention.

Question 870

After technical restoration, responders document the weakness exposed by: An Azure subscription shows an unexpected NSG rule allowing RDP from all public IPs. Which long-term control would reduce exposure to this specific pattern?

  1. Remove the unauthorized rule and restrict impacted management access
  2. Apply Azure Policy and reviewed infrastructure-as-code for NSG controls
  3. Predefine Azure snapshot and network isolation playbooks
  4. Review affected VM sign-ins and reinstate approved NSG configuration
  5. Inspect Azure Activity Log events for the network security group write operation

Explanation

Correct Answer

B:

Guardrails detect or prevent excessive ingress; this turns the weakness behind which Azure record identifies the configuration change into a measurable prevention requirement.

Incorrect Answers

A:

Restoring ingress policy reduces exposure immediately; one-time protection is not durable prevention in the decision about which Azure record identifies the configuration change.

C:

Cloud-native evidence collection should be rehearsed; the relevant condition for that step is how to retain Azure compute evidence, which is not shown for which Azure record identifies the configuration change.

D:

A corrected rule alone does not prove the server was not accessed; for which Azure record identifies the configuration change, case recovery is not future-risk control; recurrence prevention remains necessary.

E:

Control-plane activity captures resource-management changes within the retention scope; the requirement concerns which Azure record identifies the configuration change, so an investigation is not recurrence prevention.
