Credential - A credential is something that proves a persons identity, such as their Windows password.
Preboot Authentication (PBA) - Preboot Authentication serves as an extension of the BIOS or boot firmware 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 confirmed 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 simplifies 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.
