In an organization, employees are restricted from using their own storage devices, and only the company's portable storage devices are allowed. As employees are carrying the company's portable device outside their premises, the data should be protected from unauthorized access.

Which of the following techniques can be used to protect the data in a portable storage device?

Show Suggested Answer Hide Answer
Suggested Answer: B

Data encryption is the technique that can be used to protect the data in a portable storage device. Data encryption is the process of transforming data into an unreadable format using a secret key or algorithm. Only authorized parties who have the correct key or algorithm can decrypt and access the data. Data encryption provides security and privacy for the data stored on a portable storage device, such as a USB flash drive or an external hard drive, by preventing unauthorized access, modification, or disclosure. If the device is lost or stolen, the data will remain protected and inaccessible to the unauthorized user. Data encryption can be implemented using software or hardware solutions, such as BitLocker, VeraCrypt, or encrypted USB drives. Data encryption is one of the best practices for securely storing data on portable devices123. Reference:

Data resilience sounds familiar, but I can't quite recall how it applies here. I think it might be about maintaining data integrity rather than direct protection.

I feel like disk mirroring was mentioned in a different context, maybe for backup purposes, not really for securing data on a portable device.

I'm a bit unsure about data retention; I think it relates more to how long data is kept rather than protecting it, right?

I'm a bit confused by the options. Data retention and data resilience don't seem relevant to the question. I think I'll eliminate those and focus on encryption or disk mirroring.
