Bitlocker Questions

[paulyron]

Have a dell laptop is windows ten pro. Had turned on bitlocker on a while back again as i like it because everytime i turn on laptop, i need to enter the bitlocker pin and then the windows ten password in order to get access to my computer. Recall i choose the TPM with options which i made changes where i allow enhanced pin which allow me to use numbers and characters for the bitlocker pin.


Now when i enter my bitlocker pin and then it gets to the screen of me having to type my windows ten password in order to get to the desktop screen... could someone get into my desktop by bypassing this? Heard back then how anyone who forgot their windows ten password to sign in... anyone can bypass that screen easily. But because i have bitlocker turned on, does that mean someone cannot get access to the desktop without knowing the password?


So for example, say i want to go outside real quick and come back and i don't want to turn off my computer. Now when i lock my computer, is my pc protected if someone has access to the laptop? Of course if it is turned off, then it is because that person would need to know what is the bitlocker pin in the first place. But what about the locked screen? it's the same exact screen as how my laptop is when i turn on my laptop and after i enter the bitlocker screen correct? Are both are considered locked in each of these two situations? Because many times when i go out for a short bit, i would just turn off my laptop each time. But if it is protected, i would just leave it locked so i don't need to power it on again and have to open all the programs again etc. i assume its protected but now the difference is that person would just need to guess your windows ten password instead of the bitlocker pin as well? But if your windows ten password is very simple, can they brute force it? But if they try to brute force, they can't do that in your apartment right unless they have their computer equipment or whatever is needed for it?


Now assuming that person cannot access my laptop because they don't know my windows password to get access to my desktop, could they somehow brute force the password? Know you can brute force password for email accounts but could they do it with my laptop if they have access to it but its on the lock screen? But they would need to connect something physically to my laptop to brute force it? What if its on the bitlocker pin screen? Can they brute force the laptop if they have physical possession of the laptop for a long time?


Now... could that person plug in a usb with malware device into my laptop while its locked and i get malware or keylogger or virus that way? i know that if you leave your laptop unattended in say a coffeeshop for just a minute, someone could literally go to your laptop and connect a usb with malware on it and after a minute or so, unplug the usb and then you are infected... saw that on an old youtube video. That is true right? But can someone do this to your laptop if its on the lock screen? i assume this is not possible if they can't get past the bitlocker pin screen? But did hear about bios malware as well but does bitlocker protect that or not?

So is my windows ten pro laptop safe when i just lock it then as oppose to turning it off?  Can a hacker bypass the locked screen in a bitlocker enabled windows laptop?  Could they put malware on it via usb flash drive or similar while the pc is locked?  What about when not turned on at all which mean they would also need to know the bitlocker pin?

Can people tell me if my pc is safe if its in lock mode?  Only have to type in my windows password to get in... but could someone bypass this screen without the password?  Now if they have to power on the laptop, they have to enter the bitlocker pin which is the big thing here.  Someone say if you lock or make your computer sleep, its the same thing?

 

 

But if you hibernate your pc, then you need to enter your bitlocker pin and then windows password?  So if you going outside for a short time and don't want to power off your computer and turn it back on and open all your regular programs, can you just lock your pc or is it not protected?  The same as if say you go to bed and don't want to turn off your pc and just want to use it next day where all the programs that were opened before stays open etc.  Or do you do hibernate?  So hibernate protects your pc similar to powering it off... except all your programs that you have opened previously is there once you un hibernate it right by entering your bitlocker pin and then password?  But what about just locking it?  Could someone bypass it?  Or they have to know your windows password?  Could they even brute force your windows password on the lock screen?  if so, they certainly need to connect a machine to your locked laptop right if they have physical access to it?  But they can't take out the hard drive out of pc because doing that would mean they have to power off your laptop which mean they need to know the bitlocker pin.

 

 

Anyone can answer this who use bitlocker?
