ECCouncil 212-89 (EC-Council Certified Incident Handler) Practice Test 104

Question 1030

The affected workflow needs an integrity and access check following this event: A user creates several access tokens with long expiration times the day before a role transfer. What case-specific cleanup or recovery step establishes a trusted state?

  1. Revoke unauthorized tokens and prevent new issuance under outdated privileges
  2. Limit token lifetime and tie service permissions to identity lifecycle
  3. Assess whether restricted content left and remediate sharing permissions
  4. Recalculate legitimate access for the new role and audit token use

Explanation

Correct Answer

D:

Recovery separates needed capabilities from pre-transfer entitlements; the resulting state needs verification against the original concern: whether credential staging creates persistent access.

Incorrect Answers

A:

Token-specific containment closes the persistence avenue; when judging whether credential staging creates persistent access, temporary protection does not complete correction; this is instead initial containment or preservation.

B:

Access should change when employment duties change; for whether credential staging creates persistent access, future hardening is not current-state recovery; trusted restoration remains necessary.

C:

Investigation determines data scope and retention obligations; the relevant condition for that step is whether an unsanctioned channel moved restricted data, which is not shown for whether credential staging creates persistent access.

Question 1031

After technical restoration, responders document the weakness exposed by: A system owner repeatedly changes record retention to erase customer complaints after audits are announced. Which long-term control would reduce exposure to this specific pattern?

  1. Separate retention administration from business record ownership
  2. Inventory nonhuman credentials associated with contractor lifecycle
  3. Compare retention changes, deletion events and audit calendar
  4. Restore recoverable records and investigate the approval chain

Explanation

Correct Answer

A:

Independent oversight reduces insider manipulation; the control owner can test whether this reduces repeat conditions affecting whether a trusted operator is tampering with evidence.

Incorrect Answers

B:

Offboarding must include delegated and shared access; that method could help with whether a service identity provides residual insider access; the recurrence prevention decision here involves whether a trusted operator is tampering with evidence.

C:

Authorized configuration access may be abused to destroy records; when judging whether a trusted operator is tampering with evidence, an investigation is not recurrence prevention; this is instead evidence validation.

D:

Recovery should transparently note irretrievable gaps; for whether a trusted operator is tampering with evidence, case recovery is not future-risk control; recurrence prevention remains necessary.

Question 1032

A containment decision is required for this incident: A contractor uses a shared service credential to query private customer information after their contract expired. What action constrains the incident at the affected point of control?

  1. Reissue scoped credentials to current service owners and assess accessed records
  2. Rotate the exposed service secret and restrict unapproved data access
  3. Correlate database audit, service credential use and contract termination date
  4. Hold the exceptional export pending independent project-owner approval

Explanation

Correct Answer

B:

Containment closes the bypass of HR-driven identity revocation; it protects the affected workflow while investigators continue resolving whether a service identity provides residual insider access.

Incorrect Answers

A:

Recovery replaces a shared secret without breaking legitimate integrations; for whether a service identity provides residual insider access, corrective follow-through follows initial protection; initial containment or preservation remains necessary.

C:

Machine credentials can remain active independently of a terminated personal account; the goal is initial containment or preservation for whether a service identity provides residual insider access. Investigation alone does not control current conditions.

D:

Authorization checks protect against misuse without making accusations; it is meant to address whether claimed business justification can be verified, not initial containment or preservation for whether a service identity provides residual insider access.

Question 1033

To prevent the next similar event, analysts review this case: A company grants permanent domain administrator access to employees who only need temporary database maintenance. Which preventive change targets the exact pathway that failed?

  1. Migrate maintenance to scoped identities with approval and session logging
  2. Compare actual maintenance tasks with effective permanent role grants
  3. Provide safe time-bound delegation rather than shared identities
  4. Use just-in-time privileged access and periodic recertification

Explanation

Correct Answer

D:

Privilege lifecycle control reduces long-term insider risk; this turns the weakness behind whether just-in-time privilege would reduce insider opportunity into a measurable prevention requirement.

Incorrect Answers

A:

Operational recovery corrects entitlement design; the requirement concerns whether just-in-time privilege would reduce insider opportunity, so case recovery is not future-risk control.

B:

Persistent broad authority increases potential misuse and credential theft impact; the goal is recurrence prevention for whether just-in-time privilege would reduce insider opportunity. An investigation is not recurrence prevention.

C:

Usable access workflows reduce incentives to bypass policy; that method could help with whether account sharing undermines attribution; the recurrence prevention decision here involves whether just-in-time privilege would reduce insider opportunity.

Question 1034

The team wants a measurable hardening change following this situation: A developer disables audit logging on a production repository shortly before copying protected branches. What improvement best addresses the root weakness in a future incident?

  1. Alert on audit disablement and require independent approval of logging changes
  2. Compare audit-setting changes, branch downloads and privileged session records
  3. Validate repository history and revoke any covert automation tokens
  4. Monitor new data-export jobs and restrict destinations for archive storage

Explanation

Correct Answer

A:

Administrative separation makes concealment harder; a periodic review of this safeguard can track the risk described by whether monitoring suppression preceded data movement.

Incorrect Answers

B:

The sequence can reveal deliberate evasion followed by export; when judging whether monitoring suppression preceded data movement, an investigation is not recurrence prevention; this is instead evidence validation.

C:

Repair includes visibility and access channels; for whether monitoring suppression preceded data movement, case recovery is not future-risk control; recurrence prevention remains necessary.

D:

Job governance reduces stealthy recurring copies; the activity targets whether scheduled automation is an insider persistence route; recurrence prevention here concerns whether monitoring suppression preceded data movement.

Question 1035

The immediate risk must be managed. The response record describes: A privileged user deletes unusual volumes of source files and wipes local recycle bins before leave approval. Which intervention is most effective before full eradication or restoration?

  1. Freeze retention-policy changes and preserve independent backups
  2. Suspend destructive rights and protect repository snapshots
  3. Use immutable version control and alert on bulk destructive operations
  4. Correlate file-deletion events, repository activity and identity records
  5. Restore verified files and review all affected projects for hidden modifications

Explanation

Correct Answer

B:

Rapidly limiting write access preserves remaining assets; this reduces current exposure associated with whether destructive insider activity occurred and permits later corrective work.

Incorrect Answers

A:

A protective hold prevents ongoing evidentiary loss; the other incident centers on whether a trusted operator is tampering with evidence, not this initial containment or preservation question about whether destructive insider activity occurred.

C:

Protected history limits the impact of insider deletion; prevention cannot replace immediate action in the decision about whether destructive insider activity occurred.

D:

Independent deletion traces can establish activity even after user cleanup; the case needs initial containment or preservation addressing whether destructive insider activity occurred; investigation alone does not control current conditions.

E:

Recovery should cover both removal and possible tampering; when judging whether destructive insider activity occurred, corrective follow-through follows initial protection; this is instead trusted restoration.

Question 1036

During lessons learned, the security owner reviews this completed incident: A company assigns a data-loss prevention policy that blocks all attachments, causing employees to use personal messaging apps. Which repeatable safeguard best prevents this failure mode in the future?

  1. Tune classification-aware rules with business-owner input and test them
  2. Measure user friction and update DLP controls with targeted exceptions
  3. Review blocked business workflows and observed unsanctioned transfer channels
  4. Adopt purpose limitation, access controls and monitored collection approvals

Explanation

Correct Answer

B:

Effective prevention must support normal authorized operations; this turns the weakness behind whether preventive controls created unsafe workarounds into a measurable prevention requirement.

Incorrect Answers

A:

Recovery improves protection without obstructing legitimate needs; the requirement concerns whether preventive controls created unsafe workarounds, so case recovery is not future-risk control.

C:

Unusable policies may push sensitive data outside enterprise monitoring; an investigation is not recurrence prevention in the decision about whether preventive controls created unsafe workarounds.

D:

Governed insider monitoring avoids becoming a new data exposure; the activity targets whether monitoring scope is proportionate and authorized; recurrence prevention here concerns whether preventive controls created unsafe workarounds.

Question 1037

The incident is not yet closed. Response staff report: Employees routinely share passwords to cover vacation absences because no approved delegation workflow exists. Which short-term measure protects the affected process or asset?

  1. Review sign-in locations, password-sharing reports and task handoff needs
  2. Disable password sharing and assign named temporary delegates
  3. Rotate exposed passwords and implement documented delegated access
  4. Export logs to a security-owned restricted repository

Explanation

Correct Answer

B:

Individual accountability protects both investigators and staff; the immediate response addresses whether account sharing undermines attribution while the team preserves relevant case records.

Incorrect Answers

A:

Shared credentials make actions difficult to attribute reliably; the goal is initial containment or preservation for whether account sharing undermines attribution. Investigation alone does not control current conditions.

C:

Recovery preserves coverage without ambiguous logins; the case needs initial containment or preservation addressing whether account sharing undermines attribution; corrective follow-through follows initial protection.

D:

Administrative separation protects existing evidence; this serves whether monitoring is independent of monitored insiders, whereas the requested result is initial containment or preservation involving whether account sharing undermines attribution.

Question 1038

A post-incident audit examines the following failure mode: A user creates several access tokens with long expiration times the day before a role transfer. What recurring check or restriction would best address the weakness?

  1. Limit token lifetime and tie service permissions to identity lifecycle
  2. Inventory nonhuman credentials associated with contractor lifecycle
  3. Review token issue logs, scope and subsequent API calls
  4. Revoke unauthorized tokens and prevent new issuance under outdated privileges
  5. Recalculate legitimate access for the new role and audit token use

Explanation

Correct Answer

A:

Access should change when employment duties change; the control owner can test whether this reduces repeat conditions affecting whether credential staging creates persistent access.

Incorrect Answers

B:

Offboarding must include delegated and shared access; it is meant to address whether a service identity provides residual insider access, not recurrence prevention for whether credential staging creates persistent access.

C:

Long-lived tokens may bypass expected access changes after the role shift; when judging whether credential staging creates persistent access, an investigation is not recurrence prevention; this is instead evidence validation.

D:

Token-specific containment closes the persistence avenue; for whether credential staging creates persistent access, one-time protection is not durable prevention; recurrence prevention remains necessary.

E:

Recovery separates needed capabilities from pre-transfer entitlements; the requirement concerns whether credential staging creates persistent access, so case recovery is not future-risk control.

Question 1039

To distinguish suspicion from confirmed impact, the SOC examines this case: A staff member sends the customer database to a competitor using a company email account after being denied promotion. Which review would give the incident owner the strongest case-specific evidence?

  1. Correlate sensitive record reads with assigned cases and export logs
  2. Compare outbound message attachments, classification labels and recipient identity
  3. Preserve the message and suspend unauthorized bulk outbound transfers
  4. Use sensitivity labels and controlled external sharing approvals

Explanation

Correct Answer

B:

Content and destination determine suspected disclosure regardless of a valid login; the review should retain source and timing information relevant to whether a trusted mailbox was used for intentional disclosure.

Incorrect Answers

A:

Legitimate role membership does not explain accesses outside assigned duties; the activity targets whether database access patterns show insider snooping; evidence validation here concerns whether a trusted mailbox was used for intentional disclosure.

C:

Evidence retention and access control prevent further dissemination; when judging whether a trusted mailbox was used for intentional disclosure, immediate protection does not substantiate findings; this is instead initial containment or preservation.

D:

Policies can restrict high-risk transfers without blanket mail blocking; for whether a trusted mailbox was used for intentional disclosure, prevention is not incident verification; evidence validation remains necessary.

Question 1040

The response record begins with an unresolved observation: An insider changed access-control lists on hundreds of folders while masking the changes as a migration. What documentation or telemetry would most reliably support the incident determination?

  1. Use baseline ACL monitoring and approval gates for bulk changes
  2. Temporarily restrict the changed shares until permissions are reviewed
  3. Diff current ACLs against approved inheritance and change records
  4. Compare centralized version history with endpoint sync queues and restore checkpoints

Explanation

Correct Answer

C:

Bulk permission drift can hide unauthorized access beyond stolen files; the objective is to establish whether permission integrity can be restored from a baseline; the result can then guide the later protective decision.

Incorrect Answers

A:

Configuration drift detection exposes stealthy permission modification; the case needs evidence validation addressing whether permission integrity can be restored from a baseline; prevention is not incident verification.

B:

Containment closes unknown access routes; when judging whether permission integrity can be restored from a baseline, immediate protection does not substantiate findings; this is instead initial containment or preservation.

D:

Unchecked synchronization may reapply destructive changes to recovered data; that method could help with whether restoration will replay deletions; the evidence validation decision here involves whether permission integrity can be restored from a baseline.
