CompTIA CAS-005 Practice Test 1

A hospital provides tablets to its medical staff to enable them to more quickly access and edit patients' charts. The hospital wants to ensure that if a tablet is Identified as lost or stolen and a remote command is issued, the risk of data loss can be mitigated within seconds. The tablets are configured as follows to meet hospital policy
* Full disk encryption is enabled
* 'Always On' corporate VPN is enabled
* ef-use-backed keystore is enabled'ready.
* Wi-Fi 6 is configured with SAE.
* Location services is disabled.
*Application allow list is configured
Revoking the user certificates used for VPN and Wi-Fi access
Performing cryptographic obfuscation
Using geolocation to find the device
Configuring the application allow list to only per mil emergency calls
Returning on the device's solid-state media to zero
To mitigate the risk of data loss on a lost or stolen tablet quickly, the most effective strategy is to return the device's solid-state media to zero, which effectively erases all data on the device. Here's why:
Immediate Data Erasure: Returning the solid-state media to zero ensures that all data is wiped instantly, mitigating the risk of data loss if the device is lost or stolen.
Full Disk Encryption: Even though the tablets are already encrypted, physically erasing the data ensures that no residual data can be accessed if someone attempts to bypass encryption.
Compliance and Security: This method adheres to best practices for data security and compliance, ensuring that sensitive patient data cannot be accessed by unauthorized parties.
