ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 100

Question 990

After technical restoration, responders document the weakness exposed by: Privileged shared administrator accounts are common, making it impossible to tie database changes to one person. Which long-term control would reduce exposure to this specific pattern?

  1. Automate identity revocation from verified HR lifecycle events
  2. Migrate shared access to per-person privileged identities and review historical changes
  3. Compare shared-login use with individual session and bastion audit records
  4. Use privileged access management with session recording and just-in-time grants

Explanation

Correct Answer

D:

Traceability supports insider investigation and prevention; this turns the weakness behind whether insider action attribution is possible into a measurable prevention requirement.

Incorrect Answers

A:

Event-driven offboarding reduces exposure windows; that method could help with whether offboarding revokes privileges promptly; the recurrence prevention decision here involves whether insider action attribution is possible.

B:

Recovery fixes attribution and narrows privilege distribution; the case needs recurrence prevention addressing whether insider action attribution is possible; case recovery is not future-risk control.

C:

An unshared account identity is needed for reliable person-level attribution; when judging whether insider action attribution is possible, an investigation is not recurrence prevention; this is instead evidence validation.

Question 991

A containment decision is required for this incident: A compromised insider deleted a team's project files but also corrupted synchronization records on laptops. The incident owner wants a corroborating check and a protective action before recovery begins. Which TWO choices fit these separate tasks? (Choose TWO.)

  1. Pause affected synchronization clients before restoring files
  2. Compare centralized version history with endpoint sync queues and restore checkpoints
  3. Restore approved ACLs and test legitimate user access and restricted access
  4. Rotate service secrets and verify no unauthorized data pulls persist
  5. Restore verified versions and then reconcile client sync state carefully
  6. Use immutable recovery points and test mass-deletion restore procedures

Explanation

Correct Answers

A:

Containing queued state prevents re-deletion; within the combined response for whether restoration will replay deletions, this supplies initial containment or preservation: the immediate response addresses whether restoration will replay deletions while the team preserves relevant case records.

B:

Unchecked synchronization may reapply destructive changes to recovered data; within the combined response for whether restoration will replay deletions, this supplies evidence validation: the objective is to establish whether restoration will replay deletions; the result can then guide the later protective decision.

Incorrect Answers

C:

Recovery verifies both availability and confidentiality; that method could help with whether permission integrity can be restored from a baseline; the initial containment or preservation decision here involves whether restoration will replay deletions.

D:

Recovery needs evidence that continued access has stopped; it is meant to address whether access containment is complete, not initial containment or preservation for whether restoration will replay deletions.

E:

Coordinated recovery protects the restored dataset; when judging whether restoration will replay deletions, corrective follow-through follows initial protection; this is instead trusted restoration.

F:

Backup design must account for synchronization propagation; for whether restoration will replay deletions, prevention cannot replace immediate action; initial containment or preservation remains necessary.

Question 992

A technical closure review begins after this incident: A payroll clerk uses legitimate permissions to alter their own bank details in a backend system that should require separate approval. After the immediate situation is stabilized, what addresses the enabling failure?

  1. Freeze the suspect transaction and restrict the clerk's high-risk modification privileges
  2. Review accessed objects and update the erroneous runbook before reuse
  3. Restore approved payroll data and review related transactions
  4. Use separation of duties and independent approval for sensitive payroll changes

Explanation

Correct Answer

C:

Integrity review determines the business impact of misuse; the affected workflow should not be considered trusted until the issue of whether authorized access was misused outside its intended purpose is resolved.

Incorrect Answers

A:

Containment protects records while due process proceeds; for whether authorized access was misused outside its intended purpose, temporary protection does not complete correction; trusted restoration remains necessary.

B:

Recovery fixes the specific configuration and documentation failure; that method could help with whether a negligent administrative change caused exposure; the trusted restoration decision here involves whether authorized access was misused outside its intended purpose.

D:

Control design prevents single-person self-approval; future hardening is not current-state recovery in the decision about whether authorized access was misused outside its intended purpose.

Question 993

The affected workflow needs an integrity and access check following this event: A company grants permanent domain administrator access to employees who only need temporary database maintenance. What case-specific cleanup or recovery step establishes a trusted state?

  1. Migrate maintenance to scoped identities with approval and session logging
  2. Remove unnecessary standing rights and grant supervised temporary access
  3. Tune alerts to sensitive actions and peer-role deviations
  4. Implement immutable storage and independent access review for audit data
  5. Compare actual maintenance tasks with effective permanent role grants
  6. Use just-in-time privileged access and periodic recertification

Explanation

Correct Answer

A:

Operational recovery corrects entitlement design; this goes beyond temporary protection and addresses the failure identified through whether just-in-time privilege would reduce insider opportunity.

Incorrect Answers

B:

Time-bounded privileges support valid work with less exposure; for whether just-in-time privilege would reduce insider opportunity, temporary protection does not complete correction; trusted restoration remains necessary.

C:

A targeted model improves precision while preserving privacy; that method could help with whether behavior analytics has an appropriate baseline; the trusted restoration decision here involves whether just-in-time privilege would reduce insider opportunity.

D:

Evidence should remain verifiable after compromise; the activity targets whether monitoring is independent of monitored insiders; trusted restoration here concerns whether just-in-time privilege would reduce insider opportunity.

E:

Persistent broad authority increases potential misuse and credential theft impact; verification is not the corrective step in the decision about whether just-in-time privilege would reduce insider opportunity.

F:

Privilege lifecycle control reduces long-term insider risk; the case needs trusted restoration addressing whether just-in-time privilege would reduce insider opportunity; future hardening is not current-state recovery.

Question 994

A case advances from immediate protection to root-cause correction after: A senior analyst requests an export of all customer records citing a secret project but provides no authorized project ticket. Which verified recovery step is appropriate after initial containment?

  1. Hold the exceptional export pending independent project-owner approval
  2. Check access request approvals, project sponsor and prior export behavior
  3. Validate restored login functionality and investigate related changes
  4. Require documented purpose and dual approval for high-volume exports
  5. Reconcile requested data with minimum necessary project scope

Explanation

Correct Answer

E:

If approved, work should use a restricted and monitored extract; the recovery decision is tied to whether claimed business justification can be verified, not merely to reduced alert volume.

Incorrect Answers

A:

Authorization checks protect against misuse without making accusations; for whether claimed business justification can be verified, temporary protection does not complete correction; trusted restoration remains necessary.

B:

Seniority alone does not establish need for a mass data export; the requirement concerns whether claimed business justification can be verified, so verification is not the corrective step.

C:

Recovery should confirm no hidden settings remain altered; it is meant to address whether a trusted configuration change caused availability impact, not trusted restoration for whether claimed business justification can be verified.

D:

Process safeguards limit sensitive data movement; future hardening is not current-state recovery in the decision about whether claimed business justification can be verified.

Question 995

A containment decision is required for this incident: A company assigns a data-loss prevention policy that blocks all attachments, causing employees to use personal messaging apps. The incident owner wants a corroborating check and a protective action before recovery begins. Which TWO choices fit these separate tasks? (Choose TWO.)

  1. Provide an approved secure exception process and restrict actual unauthorized sharing
  2. Tune classification-aware rules with business-owner input and test them
  3. Measure user friction and update DLP controls with targeted exceptions
  4. Review blocked business workflows and observed unsanctioned transfer channels
  5. Set restricted case access and documented investigation oversight

Explanation

Correct Answers

A:

A workable controlled path reduces immediate policy bypass; within the combined response for whether preventive controls created unsafe workarounds, this supplies initial containment or preservation: it restricts the path implicated in whether preventive controls created unsafe workarounds; later eradication and restoration remain separate decisions.

D:

Unusable policies may push sensitive data outside enterprise monitoring; within the combined response for whether preventive controls created unsafe workarounds, this supplies evidence validation: this evidence is scoped to whether preventive controls created unsafe workarounds, not a generic system-health reading.

Incorrect Answers

B:

Recovery improves protection without obstructing legitimate needs; the goal is initial containment or preservation for whether preventive controls created unsafe workarounds. Corrective follow-through follows initial protection.

C:

Effective prevention must support normal authorized operations; prevention cannot replace immediate action in the decision about whether preventive controls created unsafe workarounds.

E:

Appropriate governance supports fair fact-finding; this serves whether reporting channels bypass a conflict of interest, whereas the requested result is initial containment or preservation involving whether preventive controls created unsafe workarounds.

Question 996

A long-term control assessment uses this recent event: A staff member repeatedly emails client lists to a personal account because the company laptop is inaccessible at home. Which change provides measurable prevention rather than an emergency workaround?

  1. Maintain confidential coercion reporting and strong token/device controls
  2. Offer secure remote access and enforce classification-aware email controls
  3. Secure or delete unauthorized copies through approved procedures and educate the employee
  4. Compare outgoing content classification with legitimate work requirements and policy

Explanation

Correct Answer

B:

Usable approved workflows reduce risky workarounds; it closes a repeatable gap revealed by whether careless behavior created an insider data incident without removing useful monitoring.

Incorrect Answers

A:

Supportive escalation encourages early reporting of threats; this serves whether a coerced insider enabled unauthorized access, whereas the requested result is recurrence prevention involving whether careless behavior created an insider data incident.

C:

Proportionate recovery distinguishes negligence from deliberate theft; the requirement concerns whether careless behavior created an insider data incident, so case recovery is not future-risk control.

D:

An improper transfer may arise from convenience rather than malicious intent; the goal is recurrence prevention for whether careless behavior created an insider data incident. An investigation is not recurrence prevention.

Question 997

A security analyst is asked to validate the following reported behavior: Security and HR disagree about who may approve investigation of suspected employee misconduct. Which check can confirm the relevant facts before a disruptive action?

  1. Examine the program charter, local law, employee notice and collected fields
  2. Establish an authorized joint case lead before intrusive inquiry
  3. Rehearse HR, legal and security escalation roles in insider response exercises
  4. Review incident escalation matrix, HR policies and legal-hold requirements
  5. Document approvals, evidence scope and decisions in a restricted case record

Explanation

Correct Answer

D:

Unclear decision rights can cause unlawful collection or delayed containment; it connects the question of whether insider investigations have accountable authority to an observable record and a reproducible check.

Incorrect Answers

A:

Broad surveillance can create privacy risk without improving detection; the activity targets whether monitoring scope is proportionate and authorized; evidence validation here concerns whether insider investigations have accountable authority.

B:

A coordinated process protects the investigation and affected employee; for whether insider investigations have accountable authority, immediate protection does not substantiate findings; evidence validation remains necessary.

C:

Preparation reduces conflict during sensitive incidents; the requirement concerns whether insider investigations have accountable authority, so prevention is not incident verification.

E:

Defensible case handling requires traceable authorization; recovery is not factual verification in the decision about whether insider investigations have accountable authority.

Question 998

The response record begins with an unresolved observation: The organization has no protection for privileged audit logs against modification by the same administrators being monitored. What documentation or telemetry would most reliably support the incident determination?

  1. Review log repository rights and administrator ability to change retention
  2. Export logs to a security-owned restricted repository
  3. Implement immutable storage and independent access review for audit data
  4. Compare actual maintenance tasks with effective permanent role grants
  5. Use dual control for log policy changes and alert on tampering

Explanation

Correct Answer

A:

A subject of investigation should not be able to erase the only relevant audit trail; the objective is to establish whether monitoring is independent of monitored insiders; the result can then guide the later protective decision.

Incorrect Answers

B:

Administrative separation protects existing evidence; when judging whether monitoring is independent of monitored insiders, immediate protection does not substantiate findings; this is instead initial containment or preservation.

C:

Evidence should remain verifiable after compromise; for whether monitoring is independent of monitored insiders, recovery is not factual verification; evidence validation remains necessary.

D:

Persistent broad authority increases potential misuse and credential theft impact; the relevant condition for that step is whether just-in-time privilege would reduce insider opportunity, which is not shown for whether monitoring is independent of monitored insiders.

E:

Separation of duties strengthens insider detection; the goal is evidence validation for whether monitoring is independent of monitored insiders. Prevention is not incident verification.

Question 999

The responder must establish the timeline from this observation: A privileged user deletes unusual volumes of source files and wipes local recycle bins before leave approval. Which analysis step best addresses the missing confirmation?

  1. Correlate file-deletion events, repository activity and identity records
  2. Compare audit-setting changes, branch downloads and privileged session records
  3. Compare retention changes, deletion events and audit calendar
  4. Suspend destructive rights and protect repository snapshots
  5. Use immutable version control and alert on bulk destructive operations
  6. Restore verified files and review all affected projects for hidden modifications

Explanation

Correct Answer

A:

Independent deletion traces can establish activity even after user cleanup; that evidence directly tests the concern about whether destructive insider activity occurred, rather than relying on a single unverified indicator.

Incorrect Answers

B:

The sequence can reveal deliberate evasion followed by export; this serves whether monitoring suppression preceded data movement, whereas the requested result is evidence validation involving whether destructive insider activity occurred.

C:

Authorized configuration access may be abused to destroy records; it is meant to address whether a trusted operator is tampering with evidence, not evidence validation for whether destructive insider activity occurred.

D:

Rapidly limiting write access preserves remaining assets; the case needs evidence validation addressing whether destructive insider activity occurred; immediate protection does not substantiate findings.

E:

Protected history limits the impact of insider deletion; when judging whether destructive insider activity occurred, prevention is not incident verification; this is instead recurrence prevention.

F:

Recovery should cover both removal and possible tampering; for whether destructive insider activity occurred, recovery is not factual verification; evidence validation remains necessary.

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.
