AMERICAN MEGATRENDS BIOS UPDATE V 1.4 PASSWORD
A USB recovery key can be created during password creation that can be used to recover system if password is lost or forgotten.ĪMI will begin offering this method of storing BIOS passwords immediately with the introduction of a new BIOS eModule called TpmPassword. Continuous read of TPM NVRAM with the wrong password will trigger a dictionary attack defense mechanism that will intentionally and steadily slow down an attack.Īs an added benefit of storing BIOS passwords in the TPM NVRAM, BIOS passwords are preserved even after a BIOS firmware flash and hardware reset. Malicious user cannot search NVRAM for the BIOS password hash. The TPM has inherent characteristic that counter attempts to gain access to its NVRAM. AMI has invested two years developing and testing, storing the BIOS password in the NVRAM of the TPM. However, anyone can read system NVRAM and an attacker can easily employ a Dictionary Attack, which is simply attempting to guess the password until a match is found.ĪMI raises the barrier higher with a drastically different approach not traditionally seen when it comes to BIOS password integrity. This method is easy for system manufacturers to implement and offers a good level of security because passwords are not saved in the clear. They are hashed and stored in system NVRAM. BIOS passwords are not stored in plain text. If the BIOS password is disabled by default, then the system can be infiltrated.Īdditionally, as more individuals begin to experiment with defeating BIOS passwords, the traditional method of storing the BIOS password weakens. However, it does not stop them from physically opening the system and resetting the BIOS to its default settings. Having a BIOS password along with a proper Boot Order setting, offers superior protection as it can raise the barrier against a malicious user from booting the system from external storage devices. This type of protection does not stop a malicious user from booting the system using another operating system loaded onto an external storage device such as a USB stick.īIOS passwords offer a stronger layer of system protection. This is considered the most basic form of system protection. Most end-users have a password or pin to gain access into their operating system. System security is typically considered in terms of layers of security. NORCROSS, GEORGIA: – American Megatrends International LLC (AMI), a global leader in BIOS and UEFI firmware, server and remote management tools, data storage products and unique solutions based on the Linux® and Android™ operating systems, is pleased to announce support for BIOS passwords to be stored in the TPM NVRAM via new Aptio® V UEFI Firmware eModule.
