To establish an encrypted connection (such as HTTPS/TLS) with an externally facing web server, the server must deploy a public key as part of its digital certificate. Clients use the server’s public key to initiate secure communication, which is validated by certificate authorities. The server holds the matching private key, but it is the public key that must be made available for encrypted connections to be established.

Key escrow is a method of storing encryption keys in a secure location, such as a trusted third party or a hardware security module (HSM). Key escrow is important for FDE because it allows the recovery of encrypted data in case of lost or forgotten passwords, device theft, or hardware failure. Key escrow also enables authorized access to encrypted data for legal or forensic purposes.

TPM presence is a feature of some laptops that have a dedicated chip for storing encryption keys and other security information. TPM presence is important for FDE because it enhances the security and performance of encryption by generating and protecting the keys within the chip, rather than relying on software or external devices. TPM presence also enables features such as secure boot, remote attestation, and device authentication. 

Virtualization (D)allows multiple systems and services to be hosted onfewer physical machines, therebyreducing the total number of physical devicesand consequently thehardware attack surface. This also allows for better patching, monitoring, and control.

The fewer devices you manage physically, the fewer entry points there are for attackers to exploit hardware-level vulnerabilities.
