ISC CISSP Practice Test 23
Question 220
A manufacturing firm encrypts databases at rest but service operators can download entire plaintext exports to unmanaged laptops. A designer proposes: Conclude stored-data encryption alone blocks every data loss path. What is the MOST significant security deficiency in this proposal?
- Cloud service governance requires visibility into permitted destinations and sensitive transfers.
- The system can release plaintext through application functions after decryption.
- Malware signatures do not evaluate confidentiality labels or permitted SaaS destinations.
- The new risk concerns storage of offline copies rather than live export privileges.
Explanation
Correct Answer
B:The system can release plaintext through application functions after decryption. This is the direct weakness in the proposed action.
Incorrect Answers
A:This is an advantage of another design (Use integrated CASB or SSE controls and classification-aware data loss policies across cloud flows.), not the particular flaw of Conclude stored-data encryption alone blocks every data loss path.
C:This is a limitation elsewhere: An enterprise needs to monitor classified documents moving from sanctioned SaaS to unsanctioned services. It does not explain the deficiency of the specified proposed approach.
D:This explains a later shift in requirements (A stolen powered-off backup drive contains sensitive records outside the database.), not the failure of the current proposal.
Question 221
A manufacturing firm encrypts databases at rest but service operators can download entire plaintext exports to unmanaged laptops. The organization has now implemented this response: Enforce least-privilege export rights, monitored egress and approved endpoint handling. Which observation would MOST directly demonstrate that the security objective was met?
- An approved change ticket for Enforce least-privilege export rights, monitored egress and approved endpoint handling. without a completed verification result.
- An unauthorized bulk export is blocked and creates a reviewed alert.
- A test session cannot download prohibited data and security events are attributable.
- Partner tests verify expiration, permitted viewing and traceable watermark content.
Explanation
Correct Answer
B:An unauthorized bulk export is blocked and creates a reviewed alert. This validates that at-rest encryption does not prevent authorized users from exporting decrypted content.
Incorrect Answers
A:An approved change without an executed test cannot prove operating effectiveness. The needed evidence is An unauthorized bulk export is blocked and creates a reviewed alert.
C:This demonstrates controls in another circumstance: A contractor accesses confidential service data in a browser from an unmanaged personal workstation.
D:This other observation is relevant to: A video rights company shares pre-release screeners with distribution partners and needs traceable authorized use.
Question 222
A previous security situation was: A manufacturing firm encrypts databases at rest but service operators can download entire plaintext exports to unmanaged laptops. Now the requirement changes: A stolen powered-off backup drive contains sensitive records outside the database. Which NEW action BEST answers the changed need?
- An unauthorized bulk export is blocked and creates a reviewed alert.
- Protect backup media using strong encryption with separate key management.
- Enforce least-privilege export rights, monitored egress and approved endpoint handling.
- Conclude stored-data encryption alone blocks every data loss path.
Explanation
Correct Answer
B:The new risk concerns storage of offline copies rather than live export privileges. The revised action is Protect backup media using strong encryption with separate key management.
Incorrect Answers
A:This is a record of how the initial safeguard would be checked, not an action implementing the newly requested condition: An unauthorized bulk export is blocked and creates a reviewed alert.
C:This is the appropriate response to the original situation: At-rest encryption does not prevent authorized users from exporting decrypted content. It does not directly meet the new condition.
D:This remains inappropriate: The system can release plaintext through application functions after decryption.
Question 223
A contractor accesses confidential service data in a browser from an unmanaged personal workstation. What should the security manager recommend as the MOST appropriate response to the current requirement?
- Provide approved controlled access or isolation with session-level copy and download restrictions.
- Assume HTTPS makes every endpoint session safe from local copying.
- Reassess session restrictions using compliant device posture and endpoint DLP.
- Use integrated CASB or SSE controls and classification-aware data loss policies across cloud flows.
Explanation
Correct Answer
A:Data in use may be exposed through user sessions even when storage and network encryption are configured.
Incorrect Answers
B:Transport encryption cannot stop a user from exporting visible confidential content. The proposal would not be defensible for this case.
C:This is appropriate for a later condition (The contractor later receives an organization-managed laptop under an approved project.), but it does not directly resolve the initial need. Managed endpoint trust may permit a different policy under the same classification requirements.
D:This response addresses a different condition: An enterprise needs to monitor classified documents moving from sanctioned SaaS to unsanctioned services. The present case requires the measure described by Provide approved controlled access or isolation with session-level copy and download restrictions.
Question 224
A contractor accesses confidential service data in a browser from an unmanaged personal workstation. A designer proposes: Assume HTTPS makes every endpoint session safe from local copying. What is the MOST significant security deficiency in this proposal?

Question 225
A contractor accesses confidential service data in a browser from an unmanaged personal workstation. The team must implement a defensible safeguard AND demonstrate that it works. Which TWO entries form that control-and-evidence pair? (Select TWO.)
- A test session cannot download prohibited data and security events are attributable.
- Assume HTTPS makes every endpoint session safe from local copying.
- Reassess session restrictions using compliant device posture and endpoint DLP.
- Apply rights management, access expiry and individually attributable watermarking where suitable.
- Provide approved controlled access or isolation with session-level copy and download restrictions.
Explanation
Correct Answers
A:Correct verification. The specific evidence is: A test session cannot download prohibited data and security events are attributable.
E:Correct control. Data in use may be exposed through user sessions even when storage and network encryption are configured.
Incorrect Answers
B:Transport encryption cannot stop a user from exporting visible confidential content.
C:This concerns a later and different need: The contractor later receives an organization-managed laptop under an approved project. Managed endpoint trust may permit a different policy under the same classification requirements.
D:The proposed control fits another scenario: A video rights company shares pre-release screeners with distribution partners and needs traceable authorized use. It does not directly address this scenario's primary requirement.
Question 226
A previous security situation was: A contractor accesses confidential service data in a browser from an unmanaged personal workstation. Now the requirement changes: The contractor later receives an organization-managed laptop under an approved project. Which NEW action BEST answers the changed need?
- Reassess session restrictions using compliant device posture and endpoint DLP.
- Provide approved controlled access or isolation with session-level copy and download restrictions.
- Assume HTTPS makes every endpoint session safe from local copying.
- A test session cannot download prohibited data and security events are attributable.
Explanation
Correct Answer
A:Managed endpoint trust may permit a different policy under the same classification requirements. The revised action is Reassess session restrictions using compliant device posture and endpoint DLP.
Incorrect Answers
B:This is the appropriate response to the original situation: Data in use may be exposed through user sessions even when storage and network encryption are configured. It does not directly meet the new condition.
C:This remains inappropriate: Transport encryption cannot stop a user from exporting visible confidential content.
D:This is a record of how the initial safeguard would be checked, not an action implementing the newly requested condition: A test session cannot download prohibited data and security events are attributable.
Question 227
A video rights company shares pre-release screeners with distribution partners and needs traceable authorized use. What should the security manager recommend as the MOST appropriate response to the current requirement?
- Make the raw video link publicly accessible to avoid partner authentication delays.
- Place relevant access logs and copies under a documented legal hold.
- Enforce least-privilege export rights, monitored egress and approved endpoint handling.
- Apply rights management, access expiry and individually attributable watermarking where suitable.
Explanation
Correct Answer
D:Usage enforcement and traceability complement encryption for distributed intellectual property.
Incorrect Answers
A:Public links remove identity accountability and increase uncontrolled copying. The proposal would not be defensible for this case.
B:This is appropriate for a later condition (A regulator orders evidence preservation of one disputed screener distribution.), but it does not directly resolve the initial need. Evidence preservation is additional to the normal content rights and expiry controls.
C:This response addresses a different condition: A manufacturing firm encrypts databases at rest but service operators can download entire plaintext exports to unmanaged laptops. The present case requires the measure described by Apply rights management, access expiry and individually attributable watermarking where suitable.
