ISC2 CISSP Practice Question

During a merger, your company must transmit large archives of personally identifiable information (PII) from a secure on-premises data center to a partner's private cloud over the public Internet. Regulatory requirements mandate that confidentiality and integrity be preserved even if network traffic is intercepted. Which control provides the MOST effective protection for these files while they are in transit between the two environments?

  • Establish an IPsec VPN or TLS session to encrypt the data during transmission

  • Mask sensitive fields in the data sets before initiating the transfer

  • Implement just-in-time (JIT) network access for the destination servers

  • Restrict transfer pathways to pre-approved subnets using network segmentation
