Exam CAS-005 Topic 2 Question 65 Discussion

Actual exam question for CompTIA's CAS-005 exam
Question #: 65
Topic #: 2
Consultants for a company learn that customs agents at foreign border crossings are demanding device inspections. The company wants to:
* Minimize the risk to its data by storing its most sensitive data inside of a security container.
* Obfuscate containerized data on command.
Which of the following technologies is the best way to accomplish this goal?

Suggested Answer: A Vote an answer

The best solution is to use Self-Encrypting Drives (SEDs). SEDs automatically encrypt all data stored on the disk and can be rapidly sanitized or obfuscated by deleting or altering the encryption keys. This provides immediate and secure protection if customs agents demand device access, as the sensitive data inside containers becomes unreadable without the decryption key.
Option B (eFuse) and C (UEFI) are hardware mechanisms unrelated to dynamic data protection. Option D (vTPM) provides virtualized key storage but does not obfuscate data quickly under inspection conditions. Option E (MicroSD HSM) is useful for key storage but does not protect all data at scale.
