CompTIA Security+ SY0-701 Practice Question

The correct answer is 'Use the Trusted Platform Module (TPM) on the laptops.' A TPM is a specialized chip on an endpoint device that stores RSA encryption keys specific to the host system for hardware authentication. The keys stored in the TPM are used for different security applications, such as disk encryption, which is critical for securing sensitive data on employee laptops. Moreover, the TPM can provide platform integrity verification, enhancing the overall security posture. While an HSM and Secure Enclave can offer secure storage for keys and perform cryptographic operations, they are typically external devices or isolated areas within a CPU, not embedded solutions specifically tailored for endpoint devices like laptops. A Key Management System is more of an overarching system to manage cryptographic keys throughout their lifecycle and does not provide the hardware-level storage necessary for this scenario.
