"It's more likely associated with the licensing bits than the security bits at this point," Jartelius argues, adding that "a hardware-based root of trust versus the existing PKI infrastructure with certification would not add to the ransomware solution in a significant manner."

Martin Jartelius, the chief security officer at Outpost24, told me that Microsoft would not be limiting their potential install base unless they had good reasons for their decision.
"I can't think of a single ransomware attack that would have been prevented by today's common use cases for TPM," Santana says, concluding that "there's an argument to be made that a vendor-controlled desktop experience could reduce some ransomware, but ransomware isn't a very big problem at the consumer level where this kind of vendor-controlled experience is more palatable." TPM is, Santana insists, a very poor fix for the ransomware threat.
"Microsoft's public justification for the move to TPM 2.0 is a distraction," says Mario Santana, a security fellow for threat research at Appgate. This has, perhaps predictably, set the infosec cats amongst the marketing pigeons. While Microsoft's David Weston didn't claim as much, he did write that "PCs of the future need this modern hardware root-of-trust to help protect from both common and sophisticated attacks like ransomware and more sophisticated attacks from nation-states." "It does make certain malicious persistence techniques harder," Nachreiner confirms, "preventing some, but I think it would be false to say TPMs prevent all malware and ransomware." However, it certainly doesn't prevent all malware or ransomware from getting on your computer and working. As Nachreiner says, Secure Boot makes it harder for an attacker to modify the OS or tamper with specific system files. This is where the ransomware red herring enters stage left. "While it improves the security of a device, some attacks and malware still work fine on TPM protected systems." The Windows 11 ransomware red herring Secure Boot and other security use cases TPMs offer restrict what types of attacks might work and, Nachreiner says, "will make things harder for the cybercriminal adversary." However, he also points out that it is not a panacea. "TPM use benefits home users, and overall improves their device security," he says, "by providing a secure enclave for lots of private info like security keys and certificates, this provides a way to create a hardware boot process that is secure from the start, making sure to validate the integrity of the operating systems as it loads."

"On the assumption that Windows 11 will be using full disk encryption by default utilizing the TPM," Wisniewski says, "this is important for security as used, discarded or stolen hardware is largely unencrypted due to Microsoft not including BitLocker in Windows Home." Wisniewski sees this as a giant win.

What does a TPM do?Īs to what it does, here's how David Weston, the director of enterprise and OS security at Microsoft, described TPM, "Its purpose is to help protect encryption keys, user credentials, and other sensitive data behind a hardware barrier so that malware and attackers can't access or tamper with that data." This is something already available to Windows 10 Professional users, of course, with the TPM being required to use BitLocker for full disk encryption. Open device manager, expand the 'security device' option and you'll see a TPM entry if you have one.

What's more, if you have a TPM 1.2 chip, this can likely be upgraded to TPM 2.0 by way of a firmware update from the computer vendor at no cost, rather than requiring a new hardware module to be purchased and installed.Īlthough Microsoft has withdrawn the somewhat controversial, because of the lack of detailed information it provided to users, Windows 11 compatibility checker at the moment, it's easy enough to find out if you have the TPM 2.0 component required to run Windows 11.
