Credential - A credential is something that proves a person’s identity, such as their ngerprint or their Windows password.
Preboot Authentication (PBA) - Preboot Authentication serves as an extension of the BIOS or boot rmware and guarantees a secure,
tamper-proof environment external to the operating system as a trusted authentication layer. The PBA prevents anything being read from
the hard disk, such as the operating system, until the user has conrmed they have the correct credentials.
Protected – For a self-encrypting drive (SED), a computer is protected once the SED has been activated and the Pre-boot-authentication
(PBA) is deployed.
Self-encrypting Drives (SEDs) - A hard drive that has a built-in encryption mechanism that encrypts all data stored on the media and
decrypts all data leaving the media, automatically. This type of encryption is completely transparent to the user.
Single Sign-On (SSO) - SSO simplies the logon process when multi-factor authentication is enabled at both preboot and Windows logon.
If enabled, authentication is required at preboot only, and users are automatically logged on to Windows. If not enabled, authentication may
be required multiple times.
Trusted Platform Module (TPM) - TPM is a security chip with three major functions: secure storage, measurement, and attestation. The
Encryption client uses TPM for its secure storage function. The TPM can also provide encrypted containers for the software vault.
