ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 90

Question 890

The incident is resolved, but its root weakness still requires policy attention: An Amazon EC2 instance makes unusual outbound connections and might be running an attacker-controlled process. What durable process or monitoring change would make a repeat less likely?

  1. Alert on sensitive IAM policy attachments and enforce least privilege
  2. Correlate VPC Flow Logs, host telemetry and instance identity
  3. Snapshot relevant EBS volumes and redeploy from a trusted image
  4. Maintain preapproved isolation groups and forensic snapshot procedures

Explanation

Correct Answer

D:

Prepared tooling avoids ad hoc instance termination; its effectiveness can be exercised against the warning conditions associated with how to isolate suspected AWS compute without destroying evidence.

Incorrect Answers

A:

High-impact entitlement changes should be monitored; that method could help with which AWS audit events explain privilege escalation; the recurrence prevention decision here involves how to isolate suspected AWS compute without destroying evidence.

B:

Flow records show connection metadata but not necessarily process-level causation; the requirement concerns how to isolate suspected AWS compute without destroying evidence, so an investigation is not recurrence prevention.

C:

Disk capture and clean replacement address evidence and persistence separately; the goal is recurrence prevention for how to isolate suspected AWS compute without destroying evidence. Case recovery is not future-risk control.

Question 891

A case advances from immediate protection to root-cause correction after: Investigators suspect an Amazon S3 bucket was read using a stolen access key but only management events are available. Which verified recovery step is appropriate after initial containment?

  1. Find unauthorized resources, remove them after evidence capture and reissue scoped credentials
  2. Enable appropriate S3 object data events for high-risk data stores
  3. Assess alternative evidence and restore properly scoped data-event logging
  4. Revoke the exposed key and tighten the bucket's effective access

Explanation

Correct Answer

C:

Investigation should distinguish missing logs from proof of no reads; the affected workflow should not be considered trusted until the issue of why the audit record lacks individual object reads is resolved.

Incorrect Answers

A:

Recovery includes cost and persistence cleanup; this serves which record reconstructs cross-region API actions, whereas the requested result is trusted restoration involving why the audit record lacks individual object reads.

B:

Targeted logging strengthens future disclosure investigations; the requirement concerns why the audit record lacks individual object reads, so future hardening is not current-state recovery.

D:

Stopping credential and data access is urgent despite log gaps; temporary protection does not complete correction in the decision about why the audit record lacks individual object reads.

Question 892

A containment decision is required for this incident: An account breach affects resources in several regions, but investigators search logs only in the default console region. What action constrains the incident at the affected point of control?

  1. Inventory affected regions and query relevant regional and organization-level audit sources
  2. Reconstruct resource changes across regions and restore verified configuration
  3. Restrict compromised cross-region identities while preserving logs in every affected scope
  4. Enable authorized export of existing tenant logs to protected storage

Explanation

Correct Answer

C:

Identity containment must cover all reachable deployments; this is a first-response safeguard for whether the investigation includes regional activity, not a substitute for full root-cause analysis.

Incorrect Answers

A:

Cloud resources and logging scope can vary by service and region; for whether the investigation includes regional activity, investigation alone does not control current conditions; initial containment or preservation remains necessary.

B:

A complete timeline prevents missed persistence outside the initial region; the requirement concerns whether the investigation includes regional activity, so corrective follow-through follows initial protection.

D:

Immediate preservation reduces loss from service-specific retention limits; the other incident centers on which party is responsible for tenant-specific evidence retention, not this initial containment or preservation question about whether the investigation includes regional activity.

Question 893

To prevent the next similar event, analysts review this case: An Azure administrator finds secret-read activity in a Key Vault following a privileged sign-in. Which preventive change targets the exact pathway that failed?

  1. Restrict the implicated principal's vault data access and revoke active credentials
  2. Enable suitable Key Vault diagnostics and review privileged secret access
  3. Correlate Key Vault data-plane audit events with Entra identity activity
  4. Rotate exposed secrets and inspect consumers for unauthorized use
  5. Alert on high-risk sign-ins and unexpected application credential changes

Explanation

Correct Answer

B:

Central audit collection improves visibility into sensitive operations; the assurance measure is designed around which telemetry can show secret access, rather than hiding the reported activity.

Incorrect Answers

A:

Identity and data-plane controls limit additional secret retrieval; the requirement concerns which telemetry can show secret access, so one-time protection is not durable prevention.

C:

Resource management logs alone may not show every secret read; an investigation is not recurrence prevention in the decision about which telemetry can show secret access.

D:

A previously read secret may remain useful even after permission removal; the case needs recurrence prevention addressing which telemetry can show secret access; case recovery is not future-risk control.

E:

Identity monitoring can reveal persistence beyond passwords; it is meant to address where to investigate identity and application changes, not recurrence prevention for which telemetry can show secret access.

Question 894

Service owners need a bounded short-term safeguard after observing: A suspicious user signs into Microsoft Entra ID and creates a new application credential. What immediate action addresses the active exposure and leaves evidence available?

  1. Restrict the implicated principal's vault data access and revoke active credentials
  2. Remove rogue credentials and review downstream token and consent activity
  3. Correlate Entra sign-in logs with directory audit events for credential additions
  4. Disable the compromised identity and revoke unauthorized app secrets

Explanation

Correct Answer

D:

Both user and service principal paths can retain access; it restricts the path implicated in where to investigate identity and application changes; later eradication and restoration remain separate decisions.

Incorrect Answers

A:

Identity and data-plane controls limit additional secret retrieval; the activity targets which telemetry can show secret access; initial containment or preservation here concerns where to investigate identity and application changes.

B:

Recovery must account for access granted to applications; corrective follow-through follows initial protection in the decision about where to investigate identity and application changes.

C:

Identity logs distinguish login activity from application object modifications; the case needs initial containment or preservation addressing where to investigate identity and application changes; investigation alone does not control current conditions.

Question 895

Cleanup is not considered complete. The case record describes: A Google Cloud project receives an unexpected role binding that grants broad storage access to a service account. Which remediation task is necessary rather than merely suppressing the visible symptom?

  1. Revoke the unapproved role binding and constrain the service account
  2. Determine affected objects and validate intended internal access
  3. Inspect Cloud Audit Logs for IAM policy modifications and affected principals
  4. Review actions performed under the expanded grant and restore reviewed IAM policy
  5. Use IAM Recommender and policy reviews with security monitoring

Explanation

Correct Answer

D:

Recovery requires both least-privilege restoration and scoping; the affected workflow should not be considered trusted until the issue of which Google Cloud events show entitlement changes is resolved.

Incorrect Answers

A:

Identity containment limits additional resource access; the case needs trusted restoration addressing which Google Cloud events show entitlement changes; temporary protection does not complete correction.

B:

Recovery must handle data disclosure as well as policy correction; that method could help with whether an access policy exposed cloud objects; the trusted restoration decision here involves which Google Cloud events show entitlement changes.

C:

Administrative audit records can identify who changed the binding; for which Google Cloud events show entitlement changes, verification is not the corrective step; trusted restoration remains necessary.

E:

Governance reduces excessive role grants; the goal is trusted restoration for which Google Cloud events show entitlement changes. Future hardening is not current-state recovery.

Question 896

An improvement plan must address recurrence after this case: An unknown access key downloads large volumes of objects from a cloud storage container. What should the owner add to the normal control review to reduce recurrence?

  1. Correlate data-access audit events, credential identity and object request timing
  2. Use policy-as-code checks for administrative ingress rules
  3. Assess accessed object scope and issue replacement credentials to legitimate workloads
  4. Disable or rotate the exposed key and constrain storage access
  5. Prefer short-lived workload identity and monitor bulk object reads

Explanation

Correct Answer

E:

Reducing static-key use narrows long-term credential risk; the ongoing control is targeted at whether API credentials were used for unauthorized reads, rather than a one-time emergency fix.

Incorrect Answers

A:

API activity can identify which key accessed which protected objects when logging is enabled; for whether API credentials were used for unauthorized reads, an investigation is not recurrence prevention; recurrence prevention remains necessary.

B:

Preventive review catches accidental public exposure; the activity targets whether cloud network policy introduced internet exposure; recurrence prevention here concerns whether API credentials were used for unauthorized reads.

C:

Recovery must distinguish data disclosure from service restoration; the goal is recurrence prevention for whether API credentials were used for unauthorized reads. Case recovery is not future-risk control.

D:

Stopping credential replay limits continued downloads; one-time protection is not durable prevention in the decision about whether API credentials were used for unauthorized reads.

Question 897

A post-incident audit examines the following failure mode: An organization assumes a cloud provider will preserve every customer application log after a tenant account is compromised. What recurring check or restriction would best address the weakness?

  1. Map the contract and shared-responsibility model to the affected log sources
  2. Maintain service-specific responsibility matrices and support escalation contacts
  3. Document shared-responsibility assignments in cloud incident playbooks
  4. Establish independent evidence collection and restore procedures for customer workloads

Explanation

Correct Answer

C:

Clear roles reduce response gaps across service boundaries; the assurance measure is designed around which party is responsible for tenant-specific evidence retention, rather than hiding the reported activity.

Incorrect Answers

A:

Cloud providers secure underlying services but customers often configure application logging and retention; an investigation is not recurrence prevention in the decision about which party is responsible for tenant-specific evidence retention.

B:

Prepared boundaries improve cloud incident coordination; it is meant to address which responsibility boundary controls remediation, not recurrence prevention for which party is responsible for tenant-specific evidence retention.

D:

Cloud operations cannot assume provider backups cover every investigation need; for which party is responsible for tenant-specific evidence retention, case recovery is not future-risk control; recurrence prevention remains necessary.

Question 898

The team needs temporary protection and must retain evidence. The observed event is: An AWS incident begins with unexpected IAM policy attachment to an automation role. What narrowly scoped action would best control the immediate risk?

  1. Review subsequent actions by the role and restore approved IAM permissions
  2. Remove the unauthorized policy and restrict the compromised principal
  3. Search CloudTrail management events for AttachRolePolicy and related identity operations
  4. Restore logging and restrict actors with trail-configuration permissions
  5. Alert on sensitive IAM policy attachments and enforce least privilege

Explanation

Correct Answer

B:

Privilege containment reduces potential follow-on API access; it restricts the path implicated in which AWS audit events explain privilege escalation; later eradication and restoration remain separate decisions.

Incorrect Answers

A:

Rollback requires assessing what the expanded privileges enabled; for which AWS audit events explain privilege escalation, corrective follow-through follows initial protection; initial containment or preservation remains necessary.

C:

IAM configuration changes are control-plane actions recorded by CloudTrail; the goal is initial containment or preservation for which AWS audit events explain privilege escalation. Investigation alone does not control current conditions.

D:

Protection of the audit plane helps contain further concealment; the other incident centers on whether audit tampering preceded unauthorized identities, not this initial containment or preservation question about which AWS audit events explain privilege escalation.

E:

High-impact entitlement changes should be monitored; the case needs initial containment or preservation addressing which AWS audit events explain privilege escalation; prevention cannot replace immediate action.

Question 899

The initial scene or threat protection decision concerns the following: A public Cloud Storage object is discovered in a bucket intended for internal engineering data. How should responders limit the damage while retaining the investigation trail?

  1. Revoke public grants and apply approved public-access restrictions
  2. Inspect bucket IAM, public access prevention and object request evidence
  3. Disable suspicious keys and restrict the creating principal's access
  4. Determine affected objects and validate intended internal access

Explanation

Correct Answer

A:

Immediate access changes stop new anonymous retrieval; this reduces current exposure associated with whether an access policy exposed cloud objects and permits later corrective work.

Incorrect Answers

B:

Public exposure is governed by effective policy and object-access settings; the case needs initial containment or preservation addressing whether an access policy exposed cloud objects; investigation alone does not control current conditions.

C:

Both the credential and source identity need containment; the activity targets which identity event explains potential long-lived access; initial containment or preservation here concerns whether an access policy exposed cloud objects.

D:

Recovery must handle data disclosure as well as policy correction; for whether an access policy exposed cloud objects, corrective follow-through follows initial protection; initial containment or preservation remains necessary.

Question 900

A triage analyst needs to test a report involving these details: An Azure storage account was unintentionally configured for anonymous blob reads during a migration. Which evidence collection or correlation is most relevant to this claim?

  1. Correlate Entra sign-in logs with directory audit events for credential additions
  2. Assess exposed objects and restore intended private access policies
  3. Enforce policies that disallow unnecessary public blob access
  4. Review effective container access settings and anonymous request evidence
  5. Disable unintended anonymous access while retaining request and configuration logs

Explanation

Correct Answer

D:

Storage exposure depends on both account and container configurations; it connects the question of whether object exposure resulted from public access settings to an observable record and a reproducible check.

Incorrect Answers

A:

Identity logs distinguish login activity from application object modifications; that method could help with where to investigate identity and application changes; the evidence validation decision here involves whether object exposure resulted from public access settings.

B:

Recovery includes data-sensitivity review and partner migration checks; for whether object exposure resulted from public access settings, recovery is not factual verification; evidence validation remains necessary.

C:

Preventive governance catches exposure before release; the requirement concerns whether object exposure resulted from public access settings, so prevention is not incident verification.

E:

Public retrieval should cease without erasing exposure evidence; immediate protection does not substantiate findings in the decision about whether object exposure resulted from public access settings.
