ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 84

Question 830

An improvement plan must address recurrence after this case: A suspicious user signs into Microsoft Entra ID and creates a new application credential. What should the owner add to the normal control review to reduce recurrence?

  1. Alert on high-risk sign-ins and unexpected application credential changes
  2. Enable suitable Key Vault diagnostics and review privileged secret access
  3. Remove rogue credentials and review downstream token and consent activity
  4. Correlate Entra sign-in logs with directory audit events for credential additions

Explanation

Correct Answer

A:

Identity monitoring can reveal persistence beyond passwords; the ongoing control is targeted at where to investigate identity and application changes, rather than a one-time emergency fix.

Incorrect Answers

B:

Central audit collection improves visibility into sensitive operations; the other incident centers on which telemetry can show secret access, not this recurrence prevention question about where to investigate identity and application changes.

C:

Recovery must account for access granted to applications; the goal is recurrence prevention for where to investigate identity and application changes. Case recovery is not future-risk control.

D:

Identity logs distinguish login activity from application object modifications; an investigation is not recurrence prevention in the decision about where to investigate identity and application changes.

Question 831

The owner must verify the return to a trusted state for the following: An AWS access key is used from an unapproved IP to call resource-creation APIs in multiple regions. What corrective work is needed before routine operations resume?

  1. Deactivate the exposed access key and restrict associated permissions
  2. Remove unauthorized IAM identities and reconstruct actions during the gap
  3. Find unauthorized resources, remove them after evidence capture and reissue scoped credentials
  4. Use temporary credentials and central CloudTrail monitoring

Explanation

Correct Answer

C:

Recovery includes cost and persistence cleanup; technical closure should demonstrate that the control gap behind which record reconstructs cross-region API actions is actually corrected.

Incorrect Answers

A:

Credential containment prevents new cloud resources from being created; the case needs trusted restoration addressing which record reconstructs cross-region API actions; temporary protection does not complete correction.

B:

Investigators should not assume the missing interval was benign; this serves whether audit tampering preceded unauthorized identities, whereas the requested result is trusted restoration involving which record reconstructs cross-region API actions.

D:

Short-lived identity reduces replay windows; the requirement concerns which record reconstructs cross-region API actions, so future hardening is not current-state recovery.

Question 832

To distinguish suspicion from confirmed impact, the SOC examines this case: A Google Kubernetes Engine workload reads secrets outside its namespace because the pod holds an overprivileged identity. Which review would give the incident owner the strongest case-specific evidence?

  1. Reduce the pod's permissions and isolate the affected workload
  2. Inspect Cloud Audit Logs for IAM policy modifications and affected principals
  3. Use least-privilege workload identities and admission checks
  4. Correlate Kubernetes audit records with service-account and Google IAM bindings
  5. Rotate exposed secrets and replace the workload under reviewed bindings

Explanation

Correct Answer

D:

Both cluster RBAC and cloud identity may affect reachable secrets; that evidence directly tests the concern about whether workload identity and authorization allowed the read, rather than relying on a single unverified indicator.

Incorrect Answers

A:

Scoped identity containment limits further secret access; immediate protection does not substantiate findings in the decision about whether workload identity and authorization allowed the read.

B:

Administrative audit records can identify who changed the binding; that method could help with which Google Cloud events show entitlement changes; the evidence validation decision here involves whether workload identity and authorization allowed the read.

C:

Deployment guardrails reduce overprivileged containers; when judging whether workload identity and authorization allowed the read, prevention is not incident verification; this is instead recurrence prevention.

E:

Rebuilds without permission repair can repeat the exposure; the requirement concerns whether workload identity and authorization allowed the read, so recovery is not factual verification.

Question 833

A tabletop exercise is being updated using the following real-world failure: A cloud workload uses a single static administrator credential across deployment scripts and production services. Which improvement should be tracked through the next control-assurance cycle?

  1. Test cloud response automation for idempotence and preservation steps
  2. Migrate workloads to narrowly scoped short-lived identities
  3. Use workload federation or managed identity with least privilege
  4. Inventory where the credential is stored and recent privileged API use

Explanation

Correct Answer

C:

Short-duration credentials reduce persistent access risk; the control owner can test whether this reduces repeat conditions affecting whether long-lived privileged keys enlarge compromise scope.

Incorrect Answers

A:

Safe orchestration avoids irreversible evidence loss; the activity targets whether remediation destroys evidence before acquisition; recurrence prevention here concerns whether long-lived privileged keys enlarge compromise scope.

B:

Replacing shared administrator keys supports secure recovery; for whether long-lived privileged keys enlarge compromise scope, case recovery is not future-risk control; recurrence prevention remains necessary.

D:

Shared secrets make attribution difficult and rotation disruptive; the goal is recurrence prevention for whether long-lived privileged keys enlarge compromise scope. An investigation is not recurrence prevention.

Question 834

A containment decision is required for this incident: A cloud team stores incident logs in the same account that compromised tenant administrators can delete. What action constrains the incident at the affected point of control?

  1. Validate immutable retention and repository integrity checks
  2. Revoke exposed keys and limit the attached role's effective permissions
  3. Review log repository permissions and independent audit-sink access
  4. Replicate available logs to a protected security-owned account

Explanation

Correct Answer

D:

Administrative separation helps preserve evidence during ongoing compromise; this is a first-response safeguard for whether evidence storage is isolated from suspect administrators, not a substitute for full root-cause analysis.

Incorrect Answers

A:

Trusted evidence should survive customer-workload credential theft; for whether evidence storage is isolated from suspect administrators, corrective follow-through follows initial protection; initial containment or preservation remains necessary.

B:

Immediate reduction limits unauthorized cloud operations; the other incident centers on whether long-lived privileged keys enlarge compromise scope, not this initial containment or preservation question about whether evidence storage is isolated from suspect administrators.

C:

Attacker-controlled accounts can undermine retention and chain of custody; the goal is initial containment or preservation for whether evidence storage is isolated from suspect administrators. Investigation alone does not control current conditions.

Question 835

While full remediation remains pending, the commander receives this incident report: An attacker modifies cloud object retention settings immediately before mass deletion of backup files. Which first protective measure directly limits the situation without assuming cleanup is finished?

  1. Restore copies from independent protected repositories and reapply retention controls
  2. Restore protected logging and restrict identities able to alter audit sinks
  3. Restrict identities authorized to modify retention and stop deletion operations
  4. Compare retention-configuration audit events with deletion timestamps

Explanation

Correct Answer

C:

Separating backup control from workload administration limits damage; the scope of this restriction follows whether backup immutability was weakened before destructive changes rather than indiscriminately changing unrelated assets.

Incorrect Answers

A:

Recovery requires trusted data beyond the compromised policy scope; the requirement concerns whether backup immutability was weakened before destructive changes, so corrective follow-through follows initial protection.

B:

Containment protects remaining records and future visibility; this serves whether log tampering obscured follow-on actions, whereas the requested result is initial containment or preservation involving whether backup immutability was weakened before destructive changes.

D:

A settings change can remove a safeguard immediately before data loss; the case needs initial containment or preservation addressing whether backup immutability was weakened before destructive changes; investigation alone does not control current conditions.

Question 836

For the next control cycle, the responder supplies this incident history: An account breach affects resources in several regions, but investigators search logs only in the default console region. Which ongoing safeguard should be implemented and tested?

  1. Reconstruct resource changes across regions and restore verified configuration
  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
  5. Document shared-responsibility assignments in cloud incident playbooks

Explanation

Correct Answer

B:

Broad visibility reduces geographic investigation blind spots; its effectiveness can be exercised against the warning conditions associated with whether the investigation includes regional activity.

Incorrect Answers

A:

A complete timeline prevents missed persistence outside the initial region; the goal is recurrence prevention for whether the investigation includes regional activity. Case recovery is not future-risk control.

C:

Identity containment must cover all reachable deployments; the case needs recurrence prevention addressing whether the investigation includes regional activity; one-time protection is not durable prevention.

D:

Cloud resources and logging scope can vary by service and region; when judging whether the investigation includes regional activity, an investigation is not recurrence prevention; this is instead evidence validation.

E:

Clear roles reduce response gaps across service boundaries; that method could help with which party is responsible for tenant-specific evidence retention; the recurrence prevention decision here involves whether the investigation includes regional activity.

Question 837

During lessons learned, the security owner reviews this completed incident: An AWS incident begins with unexpected IAM policy attachment to an automation role. Which repeatable safeguard best prevents this failure mode in the future?

  1. Alert on sensitive IAM policy attachments and enforce least privilege
  2. Search CloudTrail management events for AttachRolePolicy and related identity operations
  3. Use separate log archive accounts and alert on trail changes
  4. Review subsequent actions by the role and restore approved IAM permissions

Explanation

Correct Answer

A:

High-impact entitlement changes should be monitored; the control owner can test whether this reduces repeat conditions affecting which AWS audit events explain privilege escalation.

Incorrect Answers

B:

IAM configuration changes are control-plane actions recorded by CloudTrail; the goal is recurrence prevention for which AWS audit events explain privilege escalation. An investigation is not recurrence prevention.

C:

Administrative separation makes audit tampering harder; the other incident centers on whether audit tampering preceded unauthorized identities, not this recurrence prevention question about which AWS audit events explain privilege escalation.

D:

Rollback requires assessing what the expanded privileges enabled; the case needs recurrence prevention addressing which AWS audit events explain privilege escalation; case recovery is not future-risk control.

Question 838

Responders are preparing to reinstate operations after this situation: An Azure container registry shows an unauthorized image pushed under an existing trusted tag. What should be corrected before technical closure of the incident?

  1. Review affected VM sign-ins and reinstate approved NSG configuration
  2. Suspend deployment of the affected digest and restrict registry write access
  3. Redeploy a signed verified image and inspect workloads that pulled the malicious digest
  4. Create authorized disk snapshots and investigate copies before clean rebuild
  5. Enforce immutable tags, image signatures and least-privilege registry permissions
  6. Compare registry manifest digests, push audit records and pipeline release history

Explanation

Correct Answer

C:

Recovery must account for prior deployment as well as repository state; the change should be tested before unrestricted operations resume for the event involving whether mutable image tags conceal a supply-chain compromise.

Incorrect Answers

A:

A corrected rule alone does not prove the server was not accessed; the other incident centers on which Azure record identifies the configuration change, not this trusted restoration question about whether mutable image tags conceal a supply-chain compromise.

B:

Digest-level containment prevents promotion of the tainted image; the case needs trusted restoration addressing whether mutable image tags conceal a supply-chain compromise; temporary protection does not complete correction.

D:

Disk snapshots preserve storage state but do not automatically capture all RAM; the activity targets how to retain Azure compute evidence; trusted restoration here concerns whether mutable image tags conceal a supply-chain compromise.

E:

Artifact integrity controls reduce malicious replacement; the requirement concerns whether mutable image tags conceal a supply-chain compromise, so future hardening is not current-state recovery.

F:

A familiar tag can reference a different artifact after a malicious overwrite; the goal is trusted restoration for whether mutable image tags conceal a supply-chain compromise. Verification is not the corrective step.

Question 839

A technical closure review begins after this incident: An Azure storage account was unintentionally configured for anonymous blob reads during a migration. After the immediate situation is stabilized, what addresses the enabling failure?

  1. Review effective container access settings and anonymous request evidence
  2. Disable unintended anonymous access while retaining request and configuration logs
  3. Enforce policies that disallow unnecessary public blob access
  4. Assess exposed objects and restore intended private access policies
  5. Rotate exposed secrets and inspect consumers for unauthorized use

Explanation

Correct Answer

D:

Recovery includes data-sensitivity review and partner migration checks; the recovery decision is tied to whether object exposure resulted from public access settings, not merely to reduced alert volume.

Incorrect Answers

A:

Storage exposure depends on both account and container configurations; for whether object exposure resulted from public access settings, verification is not the corrective step; trusted restoration remains necessary.

B:

Public retrieval should cease without erasing exposure evidence; the requirement concerns whether object exposure resulted from public access settings, so temporary protection does not complete correction.

C:

Preventive governance catches exposure before release; the goal is trusted restoration for whether object exposure resulted from public access settings. Future hardening is not current-state recovery.

E:

A previously read secret may remain useful even after permission removal; the other incident centers on which telemetry can show secret access, not this trusted restoration question about whether object exposure resulted from public access settings.

Question 840

Post-containment analysis identified this issue for correction: An Azure subscription shows an unexpected NSG rule allowing RDP from all public IPs. Which targeted analysis or corrective follow-up determines what trusted recovery requires?

  1. Assess exposed objects and restore intended private access policies
  2. Apply Azure Policy and reviewed infrastructure-as-code for NSG controls
  3. Remove the unauthorized rule and restrict impacted management access
  4. Review affected VM sign-ins and reinstate approved NSG configuration

Explanation

Correct Answer

D:

A corrected rule alone does not prove the server was not accessed; response staff can use these findings about which Azure record identifies the configuration change to decide what eradication and recovery actually require.

Incorrect Answers

A:

Recovery includes data-sensitivity review and partner migration checks; the other incident centers on whether object exposure resulted from public access settings, not this post-containment assessment question about which Azure record identifies the configuration change.

B:

Guardrails detect or prevent excessive ingress; the case needs post-containment assessment addressing which Azure record identifies the configuration change; future hardening is not current-state recovery.

C:

Restoring ingress policy reduces exposure immediately; when judging which Azure record identifies the configuration change, temporary protection does not complete correction; this is instead initial containment or preservation.
