Question 150

A financial research firm discovers that algorithm design files and public investor materials carry the same default 'internal' label. A designer proposes: Treat all documents as public because staff need convenient collaboration. What is the MOST significant security deficiency in this proposal?

  1. Uncontrolled downgrades defeat classification policy and auditability.
  2. Authorized external release is a handling decision governed by the data owner.
  3. Only delegated information owners should authorize changes in business sensitivity.
  4. Broad disclosure can expose trade secrets and confidential investor data.

Explanation

Correct Answer

D:

Broad disclosure can expose trade secrets and confidential investor data. This is the direct weakness in the proposed action.

Incorrect Answers

A:

This is a limitation elsewhere: A multinational subsidiary asks who may downgrade the confidentiality classification of proprietary manufacturing plans. It does not explain the deficiency of the specified proposed approach.

B:

This explains a later shift in requirements (An approved investment presentation must be shared with external regulators.), not the failure of the current proposal.

C:

This is an advantage of another design (Require the accountable data owner to approve any downgrade against documented criteria.), not the particular flaw of Treat all documents as public because staff need convenient collaboration.

Question 151

A financial research firm discovers that algorithm design files and public investor materials carry the same default 'internal' label. The organization has now implemented this response: Have the information owner evaluate business impact and apply distinct classifications and handling policies. Which observation would MOST directly demonstrate that the security objective was met?

  1. A reconciliation report compares source and target classifications and exceptions.
  2. A change trail identifies owner authorization, reason and resulting protections.
  3. An approved change ticket for Have the information owner evaluate business impact and apply distinct classifications and handling policies. without a completed verification result.
  4. Sampled records demonstrate approved owners, impact-driven labels and resulting access controls.

Explanation

Correct Answer

D:

Sampled records demonstrate approved owners, impact-driven labels and resulting access controls. This validates that different loss consequences require differentiated ownership and protection.

Incorrect Answers

A:

This demonstrates controls in another circumstance: A document repository was migrated without metadata, causing classified legal exhibits to lose protective labels.

B:

This other observation is relevant to: A multinational subsidiary asks who may downgrade the confidentiality classification of proprietary manufacturing plans.

C:

An approved change without an executed test cannot prove operating effectiveness. The needed evidence is Sampled records demonstrate approved owners, impact-driven labels and resulting access controls.

Question 152

A previous security situation was: A financial research firm discovers that algorithm design files and public investor materials carry the same default 'internal' label. Now the requirement changes: An approved investment presentation must be shared with external regulators. Which NEW action BEST answers the changed need?

  1. Have the information owner evaluate business impact and apply distinct classifications and handling policies.
  2. Treat all documents as public because staff need convenient collaboration.
  3. Sampled records demonstrate approved owners, impact-driven labels and resulting access controls.
  4. Use an approved disclosure channel with classification-aware release authorization.

Explanation

Correct Answer

D:

Authorized external release is a handling decision governed by the data owner. The revised action is Use an approved disclosure channel with classification-aware release authorization.

Incorrect Answers

A:

This is the appropriate response to the original situation: Different loss consequences require differentiated ownership and protection. It does not directly meet the new condition.

B:

This remains inappropriate: Broad disclosure can expose trade secrets and confidential investor data.

C:

This is a record of how the initial safeguard would be checked, not an action implementing the newly requested condition: Sampled records demonstrate approved owners, impact-driven labels and resulting access controls.

Question 153

A document repository was migrated without metadata, causing classified legal exhibits to lose protective labels. What should the security manager recommend as the MOST appropriate response to the current requirement?

  1. Apply hold and preservation controls regardless of ordinary document classification.
  2. Require the accountable data owner to approve any downgrade against documented criteria.
  3. Reconstruct classification from authoritative records and validate labels before broadening access.
  4. Make migrated files universally accessible while ownership is investigated.

Explanation

Correct Answer

C:

Migration must preserve sensitivity decisions even when the original metadata fails to transfer.

Incorrect Answers

A:

This is appropriate for a later condition (Counsel places some exhibits under a litigation hold.), but it does not directly resolve the initial need. Legal hold obligations constrain deletion and handling in addition to confidentiality labels.

B:

This response addresses a different condition: A multinational subsidiary asks who may downgrade the confidentiality classification of proprietary manufacturing plans. The present case requires the measure described by Reconstruct classification from authoritative records and validate labels before broadening access.

D:

Unknown classification is not permission for unrestricted access. The proposal would not be defensible for this case.

Question 154

A document repository was migrated without metadata, causing classified legal exhibits to lose protective labels. A designer proposes: Make migrated files universally accessible while ownership is investigated. What is the MOST significant security deficiency in this proposal?

  1. Legal hold obligations constrain deletion and handling in addition to confidentiality labels.

Question 157

A multinational subsidiary asks who may downgrade the confidentiality classification of proprietary manufacturing plans. What should the security manager recommend as the MOST appropriate response to the current requirement?

  1. Have the information owner evaluate business impact and apply distinct classifications and handling policies.
  2. Require the accountable data owner to approve any downgrade against documented criteria.
  3. Allow any project collaborator to remove labels when sharing is inconvenient.
  4. Revoke access and use enterprise device/data controls to prevent ongoing unauthorized use.

Explanation

Correct Answer

B:

Only delegated information owners should authorize changes in business sensitivity. This directly addresses the stated situation.

Incorrect Answers

A:

This response addresses a different condition: A financial research firm discovers that algorithm design files and public investor materials carry the same default 'internal' label. The present case requires the measure described by Require the accountable data owner to approve any downgrade against documented criteria.

C:

Uncontrolled downgrades defeat classification policy and auditability. The proposal would not be defensible for this case.

D:

This is appropriate for a later condition (An employee leaves the organization while retaining synced design files.), but it does not directly resolve the initial need. Offboarding applies lifecycle and endpoint safeguards after classification has been decided.

Question 158

A multinational subsidiary asks who may downgrade the confidentiality classification of proprietary manufacturing plans. A designer proposes: Allow any project collaborator to remove labels when sharing is inconvenient. What is the MOST significant security deficiency in this proposal?

  1. Migration must preserve sensitivity decisions even when the original metadata fails to transfer.
  2. Uncontrolled downgrades defeat classification policy and auditability.
  3. Unknown classification is not permission for unrestricted access.
  4. Offboarding applies lifecycle and endpoint safeguards after classification has been decided.

Question 159

A pharmaceutical team emails high-sensitivity clinical records to a supplier using an unapproved file-transfer site. What should the security manager recommend as the MOST appropriate response to the current requirement?

  1. Provide a purpose-limited deidentified or tokenized dataset under approved controls.
  2. Implement approved secure-release printing and immediate custody and disposal procedures.
  3. Use a contract-approved encrypted transfer channel and verify recipient authorization.
  4. Send the records as a plain attachment and rely only on the recipient's NDA.

Explanation

Correct Answer

C:

Sensitive data handling must respect classification and externally approved transport controls.

Incorrect Answers

A:

This is appropriate for a later condition (The same dataset must be analyzed by the supplier without revealing patient identities.), but it does not directly resolve the initial need. Data minimization and deidentification meet the new analytic need more directly than full-identity transfer.

B:

This response addresses a different condition: Customer support staff print restricted account records but leave them in a shared printer tray overnight. The present case requires the measure described by Use a contract-approved encrypted transfer channel and verify recipient authorization.

D:

An NDA does not encrypt transit or establish secure recipient authentication. The proposal would not be defensible for this case.

Question 160

A pharmaceutical team emails high-sensitivity clinical records to a supplier using an unapproved file-transfer site. A designer proposes: Send the records as a plain attachment and rely only on the recipient's NDA. What is the MOST significant security deficiency in this proposal?

  1. Data minimization and deidentification meet the new analytic need more directly than full-identity transfer.
  2. Classification controls extend to physical custody and access to media.
  3. An NDA does not encrypt transit or establish secure recipient authentication.
  4. Markings communicate handling rules but do not impose access barriers.

Explanation

Correct Answer

C:

An NDA does not encrypt transit or establish secure recipient authentication. This is the direct weakness in the proposed action.

Incorrect Answers

A:

This explains a later shift in requirements (The same dataset must be analyzed by the supplier without revealing patient identities.), not the failure of the current proposal.

B:

This is an advantage of another design (Maintain secure locked storage with inventory, authorized checkout and chain of custody.), not the particular flaw of Send the records as a plain attachment and rely only on the recipient's NDA.

D:

This is a limitation elsewhere: A lab stores labeled confidential removable drives on an unattended open shelf with public visitor access. It does not explain the deficiency of the specified proposed approach.
