Question

An organization has decided to reduce labor costs by outsourcing back office processing of credit applications to a provider located in another country. Data sovereignty and privacy concerns raised by the security team resulted in the third-party provider only accessing and processing the data via remote desktop sessions. To facilitate communications and improve productivity, staff at the third party has been provided with corporate email accounts that are only accessible via the remote desktop sessions. Email forwarding is blocked and staff at the third party can only communicate with staff within the organization. Which of the following additional controls should be implemented to prevent data loss? (Select THREE).

Options

  • AImplement hashing of data in transit
  • BSession recording and capture
  • CDisable cross session cut and paste
  • DMonitor approved credit accounts
  • EUser access audit reviews
  • FSource IP whitelisting

Why each option

Disabling clipboard redirection, performing user access audit reviews, and whitelisting source IPs together close the primary exfiltration channels in a remote desktop outsourcing arrangement where physical data removal is the chief threat.

AImplement hashing of data in transit

Hashing data in transit provides integrity verification to detect tampering during transmission but does not prevent an authenticated user from intentionally exfiltrating data during an active session.

BSession recording and capture

Session recording is a detective control that supports post-incident forensics but does not proactively block data from being exfiltrated while a session is in progress.

CDisable cross session cut and pasteCorrect

Disabling cross-session cut and paste blocks clipboard redirection, which is the most direct mechanism for a remote user to transfer data from the protected session to their local machine, and is a critical control when RDP is the sole access method.

DMonitor approved credit accounts

Monitoring approved credit accounts is a fraud detection control applied after credit decisions are rendered and does not address data loss from the remote processing environment itself.

EUser access audit reviewsCorrect

User access audit reviews ensure that only currently authorized third-party staff retain active credentials, detecting dormant or over-privileged accounts that could be exploited to access sensitive credit application data without detection.

FSource IP whitelistingCorrect

Source IP whitelisting restricts RDP session initiation to the approved IP ranges of the third-party facility, preventing unauthorized individuals outside that location from establishing sessions even if valid credentials are compromised.
