A human resources manager stores a spreadsheet with sensitive personal information on her local workstation. The spreadsheet is the only file with sensitive data, and the name of the spreadsheet does not change.
As a security specialist, you must choose the best form of encryption to protect the spreadsheet. Your choices are:
BitLocker
BitLocker To Go
File encryption via Encrypting File System (EFS)
Folder encryption via EFS
Question: Which form of encryption would ensure the spreadsheet is always stored on the disk in encrypted format? More than one form may be correct.
