Question

While conducting online research about a company to prepare for an upcoming penetration test, a security analyst discovers detailed financial information on an investor website the company did not make public. The analyst shares this information with the Chief Financial Officer (CFO), who confirms the information is accurate, as it was recently discussed at a board of directors meeting. Many of the details are verbatim discussion comments captured by the board secretary for purposes of transcription on a mobile device. Which of the following would MOST likely prevent a similar breach in the future?

Options

  • ARemote wipe
  • BFDE

Explanation

FDE (Full Disk Encryption) encrypts all data stored on the mobile device. The most likely breach scenario here is that the secretary's mobile device (which held the verbatim meeting notes) was lost, stolen, or otherwise accessed by an unauthorized party. With FDE enabled, the transcription data would be unreadable without the decryption key, preventing exfiltration of the sensitive content. Remote wipe requires the device to be online and reachable. Geolocation only helps locate the device. eFuse is a hardware security mechanism against firmware tampering. VPN encrypts data in transit but does not protect data already stored on the device.
