I am sure that a question like this already exists and has probably been answered. I just couldn't find any results (probably due to my inability to word my question correctly).
We use laptops at work which require a hardware key (a USB) to boot the computer along with a username/password. It then boots to Windows and a different USB/Username/Password combination is required.
I am already aware on how to implement the second security feature (the windows login requiring USB as well) but can't find any information on implementing a USB requirement to pass through the boot-up process. It's very similar to having a BIOS password, though requires a USB/Username/Password combination and therefore more secure as requiring a physical token.
I am trying to implement this to provide higher than usual BIOS level security. I don't want the machine to be able to be used WITHOUT the physical access token and am not concerned with HDD security (i.e, the OS itself) as I have already implemented significant security onto that already.
i.e if somebody connects an external HDD and tries to boot onto that instead of the build in HDD (which has OS-level security), I want them to require a physical token to do so along with a username and password
The startup process should therefore go like this:
1. Power on 2. Insert USB (this is my issue) 3. Enter Username/Password 4. Boot to Windows 5. Insert seperate USB 6. Enter Windows username/password 7. Login
