Windows 10: BitLocker with TPM mode protection only?

I have a laptop which is a Dell E6440 and was just wondering if it vulnerable to these DMA attacks through Thunderbolt and Firewire methods.

Reason asking, is because I have BitLocker full disk encryption turned ON with TPM-Only protection (meaning no PIN).
Would this be fine or how can I tell if my laptop is vulnerable to DMA or Memory attacks?

Overall, is it OK to use BitLocker with TPM-only protection or do I need a PIN as well?

Bitlocker without TPM on Windows 10

Hello!

So I've looked online in Technet and other websites and found that BitLocker can work with or without a TPM. I also found that using the TPM, BitLocker can lock decryption keys in it for a safer release of those when the system starts. I also understand
that the TPM allows for BitLocker enabled systems to perform integrity scans before the OS starts. My questions is that when used without a TPM, and besides the integrity verification feature that's absent in that case, is the information in my drive still
protected correctly? I mean, if an attacker steals my computer without having the USB key on which the startup key was stored and without access to recovery keys and other unlocking mechanisms, is my data still as safely encrypted and protected as with the
TPM. I'm particularly talking about privacy here. I understand what other features are missing such as Safe Boot and other TPM related security features of BitLocker. I mean BitLocker doesn't store the keys somewhere else in the drive that's protected right?
otherwise they'll be no real protection.

Thank you!

 

Hello Fingerprint authentication doesn't work when Bitlocker TPM is enabled

I have Bitlocker enabled using TPM authentication. However, now Hello fingerprint authentication does not work to log in. If I "suspend protection" for Bitlocker, fingerprint authentication works just fine. But does not work when I re-enable Bitlocker
protection.

Anyone else see this?
