#The device cannot use a trusted platform module windows 10 windows#A combination of hard disk encryption with the Windows KIOSK mode is ideal. password), as also described in the IPC Security Guide. As a minimum, this includes limiting access the IPC to authorized users with individual authentication (e.g. Hard disk encryption including TPM must therefore be combined with further protective measures. #The device cannot use a trusted platform module windows 10 password#This is especially true if hard disk encryption is enabled but the default administrator password has not been changed. For example, as long as an unauthorized person can log on to the running IPC and use the file system at will, disk encryption can be defeated by copying or manipulating data on the running system. Hard disk encryption alone is insufficient. The hard disk cannot be decrypted outside the IPC. If the hard disk is removed, the TPM remains in the IPC. The TPM serves as a security chip that stores the key for decrypting the hard disk in a way that cannot be copied. For example, unauthorized persons should not be able to remove a hard disk from the industrial controller and manipulate or copy it with a laptop. ![]() This helps with unattended systems that to which unauthorized persons may have physical access. The idea behind combining the encryption of the hard disk by BitLocker with the TPM is that the industrial controller can still boot unattended but the hard disk cannot be removed and used in another system. ![]() The combination of BitLocker with TPM is therefore ideal for unattended startup in industrial control systems. Unattended startup without TPM and without PIN entry or plugging in a USB stick means that the hard disk could be started up in external systems. With a TPM, protection can be achieved without such additional steps. BitLocker also supports encryption without a TPM, but in this case a PIN entry or the insertion of a USB memory device with an unlock key is required when starting the system. If the system partition is to be encrypted, it makes sense to use a TPM together with BitLocker. Ideally, the encryption remains unnoticed by users and processes in the live system. When Windows processes access files, the corresponding blocks are made available in decrypted form in the RAM. The entire file system of a partition is encrypted. ![]() On IPCs running Windows 10, Microsoft's BitLocker Drive Encryption is available to protect the confidentiality of data on the hard drive. The above options are described in more detail below. Customer-developed applications can have secret key material protected by the TPM so that it cannot be copied (stolen) from the device.įurther use cases are conceivable.It can protect the integrity of the system during early startup phases, so that unauthorized tampering is detected.The hard disk of the IPC can be encrypted in such a way that it can only be decrypted in the device containing the respective individual TPM.The Trusted Platform Module (TPM) can be used on IPCs for various purposes: ![]()
