ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 102

Question 1010

The affected workflow needs an integrity and access check following this event: A compromised insider deleted a team's project files but also corrupted synchronization records on laptops. What case-specific cleanup or recovery step establishes a trusted state?

  1. Compare centralized version history with endpoint sync queues and restore checkpoints
  2. Use immutable recovery points and test mass-deletion restore procedures
  3. Review access history and regrant legitimate partners through accountable identities
  4. Pause affected synchronization clients before restoring files
  5. Restore verified versions and then reconcile client sync state carefully

Explanation

Correct Answer

E:

Coordinated recovery protects the restored dataset; the owner can validate the correction against the evidence bearing on whether restoration will replay deletions.

Incorrect Answers

A:

Unchecked synchronization may reapply destructive changes to recovered data; when judging whether restoration will replay deletions, verification is not the corrective step; this is instead evidence validation.

B:

Backup design must account for synchronization propagation; for whether restoration will replay deletions, future hardening is not current-state recovery; trusted restoration remains necessary.

C:

Recovery preserves business collaboration without orphaned links; that method could help with whether resource-level sharing survives identity disablement; the trusted restoration decision here involves whether restoration will replay deletions.

D:

Containing queued state prevents re-deletion; the goal is trusted restoration for whether restoration will replay deletions. Temporary protection does not complete correction.

Question 1011

During lessons learned, the security owner reviews this completed incident: A multinational company has no secure mechanism for employees to report suspicious actions by senior managers. Which repeatable safeguard best prevents this failure mode in the future?

  1. Maintain independent confidential reporting and nonretaliation policies
  2. Inspect whistleblowing escalation and confidential incident intake procedures
  3. Set restricted case access and documented investigation oversight
  4. Measure user friction and update DLP controls with targeted exceptions

Explanation

Correct Answer

A:

Trusted channels encourage early warnings; it closes a repeatable gap revealed by whether reporting channels bypass a conflict of interest without removing useful monitoring.

Incorrect Answers

B:

Reports against executives require independent handling to prevent suppression; the goal is recurrence prevention for whether reporting channels bypass a conflict of interest. An investigation is not recurrence prevention.

C:

Appropriate governance supports fair fact-finding; case recovery is not future-risk control in the decision about whether reporting channels bypass a conflict of interest.

D:

Effective prevention must support normal authorized operations; the other incident centers on whether preventive controls created unsafe workarounds, not this recurrence prevention question about whether reporting channels bypass a conflict of interest.

Question 1012

The incident is not yet closed. Response staff report: The organization has no protection for privileged audit logs against modification by the same administrators being monitored. Which short-term measure protects the affected process or asset?

  1. Implement immutable storage and independent access review for audit data
  2. Review log repository rights and administrator ability to change retention
  3. Remove unnecessary standing rights and grant supervised temporary access
  4. Export logs to a security-owned restricted repository

Explanation

Correct Answer

D:

Administrative separation protects existing evidence; it protects the affected workflow while investigators continue resolving whether monitoring is independent of monitored insiders.

Incorrect Answers

A:

Evidence should remain verifiable after compromise; the goal is initial containment or preservation for whether monitoring is independent of monitored insiders. Corrective follow-through follows initial protection.

B:

A subject of investigation should not be able to erase the only relevant audit trail; investigation alone does not control current conditions in the decision about whether monitoring is independent of monitored insiders.

C:

Time-bounded privileges support valid work with less exposure; the activity targets whether just-in-time privilege would reduce insider opportunity; initial containment or preservation here concerns whether monitoring is independent of monitored insiders.

Question 1013

A technical closure review begins after this incident: A company assigns a data-loss prevention policy that blocks all attachments, causing employees to use personal messaging apps. After the immediate situation is stabilized, what addresses the enabling failure?

  1. Measure user friction and update DLP controls with targeted exceptions
  2. Review prior exports and issue a corrected scoped account
  3. Tune classification-aware rules with business-owner input and test them
  4. Provide an approved secure exception process and restrict actual unauthorized sharing

Explanation

Correct Answer

C:

Recovery improves protection without obstructing legitimate needs; technical closure should demonstrate that the control gap behind whether preventive controls created unsafe workarounds is actually corrected.

Incorrect Answers

A:

Effective prevention must support normal authorized operations; for whether preventive controls created unsafe workarounds, future hardening is not current-state recovery; trusted restoration remains necessary.

B:

Remediation should assess any use of the unnecessary capability; it is meant to address whether third-party access exceeds business need, not trusted restoration for whether preventive controls created unsafe workarounds.

D:

A workable controlled path reduces immediate policy bypass; temporary protection does not complete correction in the decision about whether preventive controls created unsafe workarounds.

Question 1014

Service owners need a bounded short-term safeguard after observing: A company allows departing administrators to retain remote tokens until the end of a monthly access review. What immediate action addresses the active exposure and leaves evidence available?

  1. Require named administrative sessions before further high-risk changes
  2. Automate identity revocation from verified HR lifecycle events
  3. Compare termination timestamps with active remote sessions and token expiration
  4. Revoke the departing user's active tokens and privileged entitlements immediately
  5. Audit post-termination activity and reclaim registered devices and secrets

Explanation

Correct Answer

D:

Timely containment closes the access gap; it restricts the path implicated in whether offboarding revokes privileges promptly; later eradication and restoration remain separate decisions.

Incorrect Answers

A:

Individual accountability reduces ambiguity while investigation proceeds; the relevant condition for that step is whether insider action attribution is possible, which is not shown for whether offboarding revokes privileges promptly.

B:

Event-driven offboarding reduces exposure windows; prevention cannot replace immediate action in the decision about whether offboarding revokes privileges promptly.

C:

A delayed review leaves usable credentials after authorization ends; the case needs initial containment or preservation addressing whether offboarding revokes privileges promptly; investigation alone does not control current conditions.

E:

Offboarding completeness includes machine and application credentials; for whether offboarding revokes privileges promptly, corrective follow-through follows initial protection; initial containment or preservation remains necessary.

Question 1015

Before granting routine access again, the team reviews this case: A highly privileged administrator accidentally exposes a confidential storage share while following an outdated runbook. What must the response owner validate as part of safe recovery?

  1. Revert the unintended public access and preserve change audit records
  2. Enforce peer review and policy guardrails for high-impact permission changes
  3. Restore approved payroll data and review related transactions
  4. Compare change history, share permissions and the approved procedure version
  5. Review accessed objects and update the erroneous runbook before reuse

Explanation

Correct Answer

E:

Recovery fixes the specific configuration and documentation failure; the affected workflow should not be considered trusted until the issue of whether a negligent administrative change caused exposure is resolved.

Incorrect Answers

A:

Immediate correction stops further unauthorized reads; the goal is trusted restoration for whether a negligent administrative change caused exposure. Temporary protection does not complete correction.

B:

Defense in depth reduces errors by trusted staff; future hardening is not current-state recovery in the decision about whether a negligent administrative change caused exposure.

C:

Integrity review determines the business impact of misuse; the relevant condition for that step is whether authorized access was misused outside its intended purpose, which is not shown for whether a negligent administrative change caused exposure.

D:

The configuration difference can explain disclosure without intent to harm; when judging whether a negligent administrative change caused exposure, verification is not the corrective step; this is instead evidence validation.

Question 1016

Following initial stabilization, the team must prove recovery for this case: The security program flags every employee who works at night as a possible insider without considering job schedules. Which correction must be verified before the affected service or process is restored?

  1. Tune alerts to sensitive actions and peer-role deviations
  2. Migrate maintenance to scoped identities with approval and session logging
  3. Review analytics for bias, relevance and false-positive rates
  4. Require contextual triage before intrusive investigation or sanctions

Explanation

Correct Answer

A:

A targeted model improves precision while preserving privacy; this goes beyond temporary protection and addresses the failure identified through whether behavior analytics has an appropriate baseline.

Incorrect Answers

B:

Operational recovery corrects entitlement design; it is meant to address whether just-in-time privilege would reduce insider opportunity, not trusted restoration for whether behavior analytics has an appropriate baseline.

C:

Responsible detection limits harm and operator fatigue; future hardening is not current-state recovery in the decision about whether behavior analytics has an appropriate baseline.

D:

Fair analysis prevents unsupported escalation; the case needs trusted restoration addressing whether behavior analytics has an appropriate baseline; temporary protection does not complete correction.

Question 1017

While full remediation remains pending, the commander receives this incident report: A contractor is blackmailed into sharing a badge and VPN token with an external actor. Which first protective measure directly limits the situation without assuming cleanup is finished?

  1. Revoke affected tokens and badge access while arranging a safe reporting channel
  2. Replace credentials and investigate actions taken by the external actor
  3. Suspend unauthorized export channels and preserve access evidence with HR/legal oversight
  4. Correlate badge entry, VPN sessions and the contractor's verified report

Explanation

Correct Answer

A:

Containment should protect both systems and the threatened person; the scope of this restriction follows whether a coerced insider enabled unauthorized access rather than indiscriminately changing unrelated assets.

Incorrect Answers

B:

Recovery focuses on the unauthorized access path and resulting impact; the goal is initial containment or preservation for whether a coerced insider enabled unauthorized access. Corrective follow-through follows initial protection.

C:

Evidence-based containment limits loss without assuming every departure is malicious; the other incident centers on whether an intentional insider exfiltration occurred, not this initial containment or preservation question about whether a coerced insider enabled unauthorized access.

D:

Coercion changes intent but does not remove technical access risk; the case needs initial containment or preservation addressing whether a coerced insider enabled unauthorized access; investigation alone does not control current conditions.

Question 1018

For the next control cycle, the responder supplies this incident history: An engineer downloads source-code archives just before resigning and transfers them to a personal drive despite an explicit restriction. Which ongoing safeguard should be implemented and tested?

  1. Apply role-based source access and reviewed offboarding controls
  2. Assess transferred code, revoke residual credentials and remediate unauthorized copies where lawful
  3. Offer secure remote access and enforce classification-aware email controls
  4. Correlate repository downloads, device transfers and departing employee identity

Explanation

Correct Answer

A:

Least privilege and timely revocation lower departure-related exposure; its effectiveness can be exercised against the warning conditions associated with whether an intentional insider exfiltration occurred.

Incorrect Answers

B:

Recovery must address both disclosure and continuing access; case recovery is not future-risk control in the decision about whether an intentional insider exfiltration occurred.

C:

Usable approved workflows reduce risky workarounds; the relevant condition for that step is whether careless behavior created an insider data incident, which is not shown for whether an intentional insider exfiltration occurred.

D:

Multiple independent records can establish the movement of protected data and timing; when judging whether an intentional insider exfiltration occurred, an investigation is not recurrence prevention; this is instead evidence validation.

Question 1019

The initial scene or threat protection decision concerns the following: A former employee's shared links still grant external collaborators access after the employee's account was removed. How should responders limit the damage while retaining the investigation trail?

  1. Temporarily restrict the changed shares until permissions are reviewed
  2. Review access history and regrant legitimate partners through accountable identities
  3. Revoke unapproved links and restrict external sharing on affected repositories
  4. Inventory public and guest links created by the departed account
  5. Include sharing-link inventory in offboarding checklists

Explanation

Correct Answer

C:

Containment closes persistent data access paths; this reduces current exposure associated with whether resource-level sharing survives identity disablement and permits later corrective work.

Incorrect Answers

A:

Containment closes unknown access routes; it is meant to address whether permission integrity can be restored from a baseline, not initial containment or preservation for whether resource-level sharing survives identity disablement.

B:

Recovery preserves business collaboration without orphaned links; the case needs initial containment or preservation addressing whether resource-level sharing survives identity disablement; corrective follow-through follows initial protection.

D:

Object permissions may outlive the originating identity; for whether resource-level sharing survives identity disablement, investigation alone does not control current conditions; initial containment or preservation remains necessary.

E:

Account deletion alone may not remove delegated exposure; the requirement concerns whether resource-level sharing survives identity disablement, so prevention cannot replace immediate action.

Question 1020

The responder must establish the timeline from this observation: A data scientist accesses far more records than peers by running scripted exports at night from an approved workstation. Which analysis step best addresses the missing confirmation?

  1. Pause unapproved bulk exports while confirming project requirements
  2. Check access request approvals, project sponsor and prior export behavior
  3. Correlate query volume, time, business tasks and destination transfer records
  4. Apply behavior analytics with peer-role context and approved workload baselines

Explanation

Correct Answer

C:

Large night exports can be suspicious when outside normal assigned work; the review should retain source and timing information relevant to whether unusual legitimate tooling masks insider exfiltration.

Incorrect Answers

A:

Narrow containment avoids treating every scripted query as malicious; the requirement concerns whether unusual legitimate tooling masks insider exfiltration, so immediate protection does not substantiate findings.

B:

Seniority alone does not establish need for a mass data export; the other incident centers on whether claimed business justification can be verified, not this evidence validation question about whether unusual legitimate tooling masks insider exfiltration.

D:

Context is necessary to detect abuse without constant false alarms; the case needs evidence validation addressing whether unusual legitimate tooling masks insider exfiltration; prevention is not incident verification.
