ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 101

Question 1000

The owner must verify the return to a trusted state for the following: A system owner repeatedly changes record retention to erase customer complaints after audits are announced. What corrective work is needed before routine operations resume?

  1. Separate retention administration from business record ownership
  2. Freeze retention-policy changes and preserve independent backups
  3. Revoke credentials used by the job and assess historical archive exposure
  4. Restore recoverable records and investigate the approval chain

Explanation

Correct Answer

D:

Recovery should transparently note irretrievable gaps; it is the corrective action needed for whether a trusted operator is tampering with evidence after the immediate hazard is controlled.

Incorrect Answers

A:

Independent oversight reduces insider manipulation; the case needs trusted restoration addressing whether a trusted operator is tampering with evidence; future hardening is not current-state recovery.

B:

A protective hold prevents ongoing evidentiary loss; when judging whether a trusted operator is tampering with evidence, temporary protection does not complete correction; this is instead initial containment or preservation.

C:

Eradication must remove both automation and its access method; the relevant condition for that step is whether scheduled automation is an insider persistence route, which is not shown for whether a trusted operator is tampering with evidence.

Question 1001

The recovery owner is reviewing the underlying failure in this report: An engineer downloads source-code archives just before resigning and transfers them to a personal drive despite an explicit restriction. Which targeted analysis or corrective follow-up determines what trusted recovery requires?

  1. Replace credentials and investigate actions taken by the external actor
  2. Assess transferred code, revoke residual credentials and remediate unauthorized copies where lawful
  3. Apply role-based source access and reviewed offboarding controls
  4. Suspend unauthorized export channels and preserve access evidence with HR/legal oversight

Explanation

Correct Answer

B:

Recovery must address both disclosure and continuing access; this post-containment check determines the remaining scope relevant to whether an intentional insider exfiltration occurred before the case is closed.

Incorrect Answers

A:

Recovery focuses on the unauthorized access path and resulting impact; the other incident centers on whether a coerced insider enabled unauthorized access, not this post-containment assessment question about whether an intentional insider exfiltration occurred.

C:

Least privilege and timely revocation lower departure-related exposure; future hardening is not current-state recovery in the decision about whether an intentional insider exfiltration occurred.

D:

Evidence-based containment limits loss without assuming every departure is malicious; the case needs post-containment assessment addressing whether an intentional insider exfiltration occurred; temporary protection does not complete correction.

Question 1002

A case advances from immediate protection to root-cause correction after: An insider changed access-control lists on hundreds of folders while masking the changes as a migration. Which verified recovery step is appropriate after initial containment?

  1. Use baseline ACL monitoring and approval gates for bulk changes
  2. Diff current ACLs against approved inheritance and change records
  3. Restore verified versions and then reconcile client sync state carefully
  4. Temporarily restrict the changed shares until permissions are reviewed
  5. Restore approved ACLs and test legitimate user access and restricted access

Explanation

Correct Answer

E:

Recovery verifies both availability and confidentiality; the recovery decision is tied to whether permission integrity can be restored from a baseline, not merely to reduced alert volume.

Incorrect Answers

A:

Configuration drift detection exposes stealthy permission modification; for whether permission integrity can be restored from a baseline, future hardening is not current-state recovery; trusted restoration remains necessary.

B:

Bulk permission drift can hide unauthorized access beyond stolen files; the requirement concerns whether permission integrity can be restored from a baseline, so verification is not the corrective step.

C:

Coordinated recovery protects the restored dataset; the relevant condition for that step is whether restoration will replay deletions, which is not shown for whether permission integrity can be restored from a baseline.

D:

Containment closes unknown access routes; temporary protection does not complete correction in the decision about whether permission integrity can be restored from a baseline.

Question 1003

A tabletop exercise is being updated using the following real-world failure: An insider changed access-control lists on hundreds of folders while masking the changes as a migration. Which improvement should be tracked through the next control-assurance cycle?

  1. Use baseline ACL monitoring and approval gates for bulk changes
  2. Restore approved ACLs and test legitimate user access and restricted access
  3. Diff current ACLs against approved inheritance and change records
  4. Use immutable recovery points and test mass-deletion restore procedures

Explanation

Correct Answer

A:

Configuration drift detection exposes stealthy permission modification; it closes a repeatable gap revealed by whether permission integrity can be restored from a baseline without removing useful monitoring.

Incorrect Answers

B:

Recovery verifies both availability and confidentiality; for whether permission integrity can be restored from a baseline, case recovery is not future-risk control; recurrence prevention remains necessary.

C:

Bulk permission drift can hide unauthorized access beyond stolen files; the requirement concerns whether permission integrity can be restored from a baseline, so an investigation is not recurrence prevention.

D:

Backup design must account for synchronization propagation; the relevant condition for that step is whether restoration will replay deletions, which is not shown for whether permission integrity can be restored from a baseline.

Question 1004

Forensic review begins with this reported event: A staff member repeatedly emails client lists to a personal account because the company laptop is inaccessible at home. Which evidence-based task answers the primary uncertainty?

  1. Compare outgoing content classification with legitimate work requirements and policy
  2. Stop unsafe forwarding and provide an approved remote-work alternative
  3. Compare change history, share permissions and the approved procedure version
  4. Offer secure remote access and enforce classification-aware email controls

Explanation

Correct Answer

A:

An improper transfer may arise from convenience rather than malicious intent; the review should retain source and timing information relevant to whether careless behavior created an insider data incident.

Incorrect Answers

B:

Containment protects data while addressing the business cause; the case needs evidence validation addressing whether careless behavior created an insider data incident; immediate protection does not substantiate findings.

C:

The configuration difference can explain disclosure without intent to harm; the relevant condition for that step is whether a negligent administrative change caused exposure, which is not shown for whether careless behavior created an insider data incident.

D:

Usable approved workflows reduce risky workarounds; for whether careless behavior created an insider data incident, prevention is not incident verification; evidence validation remains necessary.

Question 1005

The team requires traceable proof for an event described as follows: An employee sends a file through an encrypted web service that is not in the approved transfer list. What should be correlated to determine whether the case finding is justified?

  1. Block the unauthorized transfer mechanism and retain policy evidence
  2. Compare outbound message attachments, classification labels and recipient identity
  3. Use classification-aware DLP and sanctioned secure sharing services
  4. Correlate DLP classification, proxy upload metadata and device file access

Explanation

Correct Answer

D:

Encrypted transport alone does not establish misuse; content and policy context matter; the objective is to establish whether an unsanctioned channel moved restricted data; the result can then guide the later protective decision.

Incorrect Answers

A:

Containment should focus on confirmed unauthorized movement; the goal is evidence validation for whether an unsanctioned channel moved restricted data. Immediate protection does not substantiate findings.

B:

Content and destination determine suspected disclosure regardless of a valid login; that method could help with whether a trusted mailbox was used for intentional disclosure; the evidence validation decision here involves whether an unsanctioned channel moved restricted data.

C:

Employees need approved alternatives to personal transfer tools; the case needs evidence validation addressing whether an unsanctioned channel moved restricted data; prevention is not incident verification.

Question 1006

A security analyst is asked to validate the following reported behavior: Privileged shared administrator accounts are common, making it impossible to tie database changes to one person. Which check can confirm the relevant facts before a disruptive action?

  1. Compare shared-login use with individual session and bastion audit records
  2. Require named administrative sessions before further high-risk changes
  3. Use privileged access management with session recording and just-in-time grants
  4. Migrate shared access to per-person privileged identities and review historical changes
  5. Compare granted roles with contract scope and approved data requirements

Explanation

Correct Answer

A:

An unshared account identity is needed for reliable person-level attribution; for this investigation, the relevant uncertainty is whether insider action attribution is possible, so independent confirmation matters.

Incorrect Answers

B:

Individual accountability reduces ambiguity while investigation proceeds; for whether insider action attribution is possible, immediate protection does not substantiate findings; evidence validation remains necessary.

C:

Traceability supports insider investigation and prevention; the requirement concerns whether insider action attribution is possible, so prevention is not incident verification.

D:

Recovery fixes attribution and narrows privilege distribution; the goal is evidence validation for whether insider action attribution is possible. Recovery is not factual verification.

E:

Excess permission increases potential damage from misuse or compromise; the other incident centers on whether third-party access exceeds business need, not this evidence validation question about whether insider action attribution is possible.

Question 1007

An evidence-led review starts with the following report: The insider-threat program collects browsing history on every employee with no defined purpose or legal review. What investigation should establish the disputed activity and its timeline?

  1. Limit collection to documented security purposes with controlled retention
  2. Review incident escalation matrix, HR policies and legal-hold requirements
  3. Adopt purpose limitation, access controls and monitored collection approvals
  4. Examine the program charter, local law, employee notice and collected fields
  5. Pause excessive collection pending HR, legal and privacy review

Explanation

Correct Answer

D:

Broad surveillance can create privacy risk without improving detection; it makes the determination of whether monitoring scope is proportionate and authorized defensible and reviewable by the incident owner.

Incorrect Answers

A:

Operational recovery includes appropriate handling of already gathered records; the goal is evidence validation for whether monitoring scope is proportionate and authorized. Recovery is not factual verification.

B:

Unclear decision rights can cause unlawful collection or delayed containment; that method could help with whether insider investigations have accountable authority; the evidence validation decision here involves whether monitoring scope is proportionate and authorized.

C:

Governed insider monitoring avoids becoming a new data exposure; the case needs evidence validation addressing whether monitoring scope is proportionate and authorized; prevention is not incident verification.

E:

A lawful, targeted approach preserves trust and investigation defensibility; for whether monitoring scope is proportionate and authorized, immediate protection does not substantiate findings; evidence validation remains necessary.

Question 1008

The team has retained the initial evidence and is assessing recovery from: An administrator covertly configures an automated nightly job to copy audit archives to personal cloud storage. What restoration task closes the identified integrity or control gap?

  1. Revoke credentials used by the job and assess historical archive exposure
  2. Recalculate legitimate access for the new role and audit token use
  3. Inspect scheduler configuration, identity grants and cloud upload records
  4. Disable the unauthorized job and block its external storage destination
  5. Monitor new data-export jobs and restrict destinations for archive storage

Explanation

Correct Answer

A:

Eradication must remove both automation and its access method; this goes beyond temporary protection and addresses the failure identified through whether scheduled automation is an insider persistence route.

Incorrect Answers

B:

Recovery separates needed capabilities from pre-transfer entitlements; this serves whether credential staging creates persistent access, whereas the requested result is trusted restoration involving whether scheduled automation is an insider persistence route.

C:

A recurring job can continue exfiltration without interactive logins; the requirement concerns whether scheduled automation is an insider persistence route, so verification is not the corrective step.

D:

Containment stops the unattended transfer path; the goal is trusted restoration for whether scheduled automation is an insider persistence route. Temporary protection does not complete correction.

E:

Job governance reduces stealthy recurring copies; future hardening is not current-state recovery in the decision about whether scheduled automation is an insider persistence route.

Question 1009

Before destructive cleanup is authorized, the team faces this situation: Following insider data theft, a business team declares success once the suspect user is suspended despite active shared credentials. Which protective response should the coordinator authorize now?

  1. Inventory related shared tokens, sessions and delegated resources
  2. Disable the unauthorized account and stop associated scheduled jobs
  3. Minimize shared secrets and use attributable identities with revocation hooks
  4. Rotate service secrets and verify no unauthorized data pulls persist
  5. Revoke exposed shared credentials and review delegated grants

Explanation

Correct Answer

E:

Comprehensive identity containment reduces further data retrieval; the scope of this restriction follows whether access containment is complete rather than indiscriminately changing unrelated assets.

Incorrect Answers

A:

One disabled login may leave alternate authorized routes functional; investigation alone does not control current conditions in the decision about whether access containment is complete.

B:

Removing nonhuman access blocks post-departure connection; the other incident centers on whether non-person identity persistence remains, not this initial containment or preservation question about whether access containment is complete.

C:

Individual authorization improves incident control; when judging whether access containment is complete, prevention cannot replace immediate action; this is instead recurrence prevention.

D:

Recovery needs evidence that continued access has stopped; for whether access containment is complete, corrective follow-through follows initial protection; initial containment or preservation remains necessary.

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.
