Security
Question
A newly established CSP allows for drive shipping to upload new data into the environment. Sensitive data on 40TB of storage needs to be transferred within one week. Which of the following is the MOST efficient and secure method for shipment of the data to the CSP with minimal downtime?
Options
- ACreate a VPN between the sites and schedule data transfer during non-business hours.
- BCopy the data to encrypted drives and use the CSP-certified shipping provider.
- CCompress and SFTP the data to the CSP.
- DMove the data to encrypted drives and use the CSP-certified shipping provider.
Explanation
Physical drive shipping is the most efficient and secure method for transferring 40TB to a CSP within one week, as network-based transfers cannot handle that volume in the given timeframe.
Common mistakes.
- A. A VPN lacks the throughput required to transfer 40TB within one week, making this approach impractical for the given volume and timeline.
- B. Copying the data leaves the original sensitive data on the source drives, creating dual-residency of sensitive data and a larger attack surface compared to moving it.
- C. SFTP over a standard internet connection cannot transfer 40TB within one week due to bandwidth and latency constraints.
