ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 13

Question 120

After technical restoration, responders document the weakness exposed by: An alert involving payment-card data was categorized low because only one host was affected. Which long-term control would reduce exposure to this specific pattern?

  1. Publish severity definitions with worked examples and training
  2. Reassess scope and record the corrected severity and response deadlines
  3. Include data sensitivity and regulatory triggers in triage scoring
  4. Review affected data classification together with host criticality and exposure

Explanation

Correct Answer

C:

Impact criteria prevent host-count-only severity mistakes; this turns the weakness behind whether incident priority reflects business impact into a measurable prevention requirement.

Incorrect Answers

A:

Common interpretation reduces repeated classification disputes; this serves how to normalize severity across organizational units, whereas the requested result is readiness improvement involving whether incident priority reflects business impact.

B:

An impact-driven case update fixes the prioritization error before closure; the case needs readiness improvement addressing whether incident priority reflects business impact; case recovery is not future-risk control.

D:

Business sensitivity can outweigh the number of visibly impacted machines; for whether incident priority reflects business impact, an investigation is not recurrence prevention; readiness improvement remains necessary.

Question 121

Before revising the playbook, the incident manager checks the following: A response plan cites NIST SP 800-61 Revision 2 as the latest guidance in a 2026 audit. What investigation or readiness check is most appropriate for these facts?

  1. Check the publication revision and supersession notice in NIST CSRC
  2. Schedule periodic review of external standard references and change notices
  3. Inspect playbook tests, incident records and assigned responsibilities
  4. Flag the reference for governance correction without abandoning active response procedures

Explanation

Correct Answer

A:

NIST finalized Revision 3 in April 2025, replacing the 2012 guide; that check tests whether cited incident-response guidance is current without assuming that a policy citation alone proves operational compliance.

Incorrect Answers

B:

Document owners can update playbooks when authoritative guidance changes; the case needs process validation addressing whether cited incident-response guidance is current; prevention is not incident verification.

C:

Actual execution records demonstrate implementation where a citation to guidance alone does not; the relevant condition for that step is the gap between guidance adoption and operational evidence, which is not shown for whether cited incident-response guidance is current.

D:

A citation update must not interrupt evidence preservation during a live incident; for whether cited incident-response guidance is current, immediate protection does not substantiate findings; process validation remains necessary.

Question 122

The response coordinator tests a weakness described in these records: An automation service account can modify security policies across every tenant despite serving one investigation workspace. What case-specific check would establish how this response procedure failed?

  1. Compare the automation runbook with required evidence snapshot checkpoints
  2. Review SOAR identities and permissions whenever playbooks change
  3. Rotate its secret and reissue role grants after approval testing
  4. Restrict the credential to approved incident actions and affected resources
  5. Enumerate the integration identity's effective permissions and target scopes

Explanation

Correct Answer

E:

Excessive cross-tenant grants increase the impact of automation mistakes; that check tests whether orchestration violates least privilege without assuming that a policy citation alone proves operational compliance.

Incorrect Answers

A:

A missing acquisition step explains why terminated resources lost relevant artifacts; it is meant to address whether destructive automation has preservation safeguards, not process validation for whether orchestration violates least privilege.

B:

Continuous access governance prevents authorization drift; the requirement concerns whether orchestration violates least privilege, so prevention is not incident verification.

C:

Credential replacement and entitlement review restore trust in the integration; the goal is process validation for whether orchestration violates least privilege. Recovery is not factual verification.

D:

Least-privilege scoping shrinks the possible blast radius of a compromised integration; immediate protection does not substantiate findings in the decision about whether orchestration violates least privilege.

Question 123

For the next control cycle, the responder supplies this incident history: An intrusion drill finds that the isolation runbook references network ports moved during last quarter's redesign. Which ongoing safeguard should be implemented and tested?

  1. Compare the runbook network map with live segmentation and routing inventory
  2. Revise and exercise the playbook against current network dependencies
  3. Treat infrastructure changes as triggers for playbook maintenance
  4. Predefine emergency network-change authorities and rollback criteria

Explanation

Correct Answer

C:

Change-driven review prevents stale emergency instructions; the ongoing control is targeted at whether playbooks match current architecture, rather than a one-time emergency fix.

Incorrect Answers

A:

Outdated topology can make otherwise sound containment instructions ineffective; the goal is readiness improvement for whether playbooks match current architecture. An investigation is not recurrence prevention.

B:

Tested updates restore confidence that specified actions will work; case recovery is not future-risk control in the decision about whether playbooks match current architecture.

D:

A tested authorization path prevents uncontrolled containment disruption; the activity targets the control approval missing from the change; readiness improvement here concerns whether playbooks match current architecture.

Question 124

An incident-process audit asks for a defensible finding about this case: Night-shift responders repeatedly miss handoffs for unresolved lateral-movement cases. Which assessment task resolves the central procedural uncertainty?

  1. Use a formal shift handoff with a current incident commander
  2. Compare shift-change tickets against active incident action logs
  3. Sample fast-closed cases for evidence completeness and recurrence
  4. Mandate a minimum handoff checklist and acknowledged ownership transfer

Explanation

Correct Answer

B:

Unassigned tasks and incomplete status fields show where ownership information was lost; the review establishes the missing continuity of incident response so that responsibility and next decisions rest on a recorded result.

Incorrect Answers

A:

Explicit transfer retains command responsibility while the investigation continues; the case needs process validation addressing the missing continuity of incident response; immediate protection does not substantiate findings.

C:

Closure time alone cannot establish whether the attack was actually resolved; the relevant condition for that step is whether speed metrics reward poor incident decisions, which is not shown for the missing continuity of incident response.

D:

Standardized continuity reduces delays during overnight escalation; the requirement concerns the missing continuity of incident response, so prevention is not incident verification.

Question 125

A case closure review must correct this incident-management failure: A ransomware alert has no assigned communication owner, and public relations releases contradictory information. What corrective record or operational change resolves this process weakness?

  1. Remove persistence and validate the host before controlled reintegration
  2. Centralize stakeholder communication under the incident commander and approved spokesperson
  3. Preassign spokespersons, approval gates and communication templates
  4. Issue a corrected, fact-checked situation report with known uncertainties

Explanation

Correct Answer

D:

Controlled updates restore reliable communication without asserting unverified facts; the affected handling process should be validated against what made external incident messaging inconsistent after the change.

Incorrect Answers

A:

Containment alone does not remove the executable or its scheduled startup path; the activity targets which action limits ongoing exfiltration; procedural correction here concerns what made external incident messaging inconsistent.

B:

Single-source approval reduces speculation and contradictory disclosures; for what made external incident messaging inconsistent, temporary protection does not complete correction; procedural correction remains necessary.

C:

A rehearsal-tested plan makes crisis messages consistent; the requirement concerns what made external incident messaging inconsistent, so future hardening is not current-state recovery.

Question 126

A long-term control assessment uses this recent event: An automated credential-revocation workflow succeeded in the identity provider but the ticket still reads pending. Which change provides measurable prevention rather than an emergency workaround?

  1. Repair the workflow callback and re-run an idempotent status check
  2. Monitor action completion receipts rather than workflow invocation alone
  3. Reconcile identity audit events with the playbook's callback and error logs
  4. Use tested SOAR integrations with access-scoped service identities

Explanation

Correct Answer

B:

End-to-end confirmation catches silent integration and acknowledgement failures; the control owner can test whether this reduces repeat conditions affecting why orchestration status differs from control state.

Incorrect Answers

A:

Idempotency avoids multiple side effects when a status update is retried; when judging why orchestration status differs from control state, case recovery is not future-risk control; this is instead procedural correction.

C:

A missing acknowledgement can leave the case stale despite an executed revocation; the requirement concerns why orchestration status differs from control state, so an investigation is not recurrence prevention.

D:

Controlled integrations reduce transcription errors without granting unnecessary privileges; the relevant condition for that step is where manual coordination delays indicator response, which is not shown for why orchestration status differs from control state.

Question 127

A response-governance owner reviews a documented failure: A monitoring alert is copied into email threads but never receives an incident identifier or accountable owner. Which targeted review or exercise would most directly validate this process gap?

  1. Search the ticket queue for an immutable case identifier and assignment history
  2. Open a central incident record and assign an authorized handler
  3. Review closed case records for corrective actions and unresolved causal factors
  4. Require intake forms with time, source, severity, affected assets and owner

Explanation

Correct Answer

A:

Unstructured emails do not provide the consistent audit trail needed for response governance; the review establishes how incident recording supports traceability so that responsibility and next decisions rest on a recorded result.

Incorrect Answers

B:

A single case record makes containment and escalation attributable; the goal is process validation for how incident recording supports traceability. Immediate protection does not substantiate findings.

C:

A complete lessons-learned record should identify why controls failed or succeeded; that method could help with what post-incident learning is missing; the process validation decision here involves how incident recording supports traceability.

D:

Consistent minimum fields improve triage and handoff; the case needs process validation addressing how incident recording supports traceability; prevention is not incident verification.

Question 128

The organization needs to repair the response procedure after: A team treats an ISO/IEC 27035 guideline as proof that its incident response controls were implemented. Which follow-up would repair the reported response-management failure?

  1. Commission a control effectiveness review rather than declaring compliance
  2. Build a cohesive intrusion timeline with mapped ATT&CK techniques
  3. Close documented gaps with exercised procedures and retained results
  4. Link each guidance requirement to an accountable control and test frequency

Explanation

Correct Answer

C:

Corrective evidence supports defensible claims about operational readiness; the correction restores accountability or sequence for the gap between guidance adoption and operational evidence before case sign-off.

Incorrect Answers

A:

Independent evaluation reveals untested steps before they are relied upon; for the gap between guidance adoption and operational evidence, temporary protection does not complete correction; procedural correction remains necessary.

B:

A technique map helps explain behavior without replacing incident evidence; that method could help with how technique mapping relates to incident grouping; the procedural correction decision here involves the gap between guidance adoption and operational evidence.

D:

Traceability makes standards mappings measurable; future hardening is not current-state recovery in the decision about the gap between guidance adoption and operational evidence.

Question 129

The recurrence-prevention decision is based on this report: An analyst wants to notify affected customers immediately after a suspected personal-data leak without consulting legal counsel. What measure strengthens readiness against the observed event?

  1. Establish data categories, affected jurisdictions, certainty and exposure timeline
  2. Document the notification decision, recipients, deadlines and legal basis
  3. Maintain a reviewed jurisdiction-and-contract notification register
  4. Embed jurisdiction-specific privacy triggers in the response notification matrix

Explanation

Correct Answer

D:

Preplanned legal routing minimizes missed deadlines and unauthorized statements; a periodic review of this safeguard can track the risk described by whether notification requirements are factually triggered.

Incorrect Answers

A:

Applicable notice rules depend on governing law and the actual nature of the breach; the case needs readiness improvement addressing whether notification requirements are factually triggered; an investigation is not recurrence prevention.

B:

A reviewable decision trail supports timely compliance when duties apply; when judging whether notification requirements are factually triggered, case recovery is not future-risk control; this is instead procedural correction.

C:

Legal and vendor requirements can be checked rapidly during an incident; the other incident centers on which legal requirements govern notification timing, not this readiness improvement question about whether notification requirements are factually triggered.

Question 130

A case commander must regain control of an open handling problem: An alert on a production database has high confidence but the scope is unknown and the assigned analyst wants to close it. Which immediate decision would restore control of the ongoing handling process?

  1. Record the final validated scope, disposition and decision rationale
  2. Pause individual account sanctions until attribution is independently validated
  3. Check alert provenance, related events and the database's business criticality
  4. Escalate the case for scoped investigation under the critical-asset rule

Explanation

Correct Answer

D:

Preserving an active investigation prevents premature closure of a high-impact event; the case needs an authorized near-term step for what triage must establish before closure, with longer-term playbook changes handled separately.

Incorrect Answers

A:

Closure requires corroborating evidence and documented review; corrective follow-through follows initial protection in the decision about what triage must establish before closure.

B:

Evidence-based escalation avoids disrupting an innocent user's access; it is meant to address how to attribute network activity reliably, not immediate response coordination for what triage must establish before closure.

C:

Severity and scope cannot be inferred solely from a detector confidence score; when judging what triage must establish before closure, investigation alone does not control current conditions; this is instead process validation.
