I assume if I use Bitlocker on Windows 10 on a laptop with a TPM chip without a password, then if the laptop gets stolen, then the attacker can simply turn the machine on and then he gets to the windows logon screen without any problems.
To prevent this I assume I need the preboot pin, but how secure is that (with a 9 character numerical pin)?
The scenario I want to protect myself against:
- A simple thief steals the notebook
- They want to access the data by basic "googling around" hacking skills, like using a tool or typing in random passwords.
Meanwhile I will have time to change all the passwords of the online services, disable VPN accounts, etc. that were used on that notebook, so even if they eventually gain access, our systems will stay secure.
