I am researching how to be FIPS140-2 level 1 compliant using BitLocker encryption on Windows 7 and Windows 10. My question regarding this is such, does BitLocker encryption need to be FDE (which Windows 7 only uses), but with Windows 10 does it require FDE or is used space only allow, and second must it use AES-256 bit or is AES-128 allowed? Can you please reference in the NIST documentation that states the requirement, please?
Software/Hardware used: TPM 1.2 enabled chip on systems, Windows 7 Enterprise and Windows 10
