Thumbs up Hiding Linux Partitions from Third Party Software


Hello everyone!
I am a new member and excited to join LinuxQuestions.org!

Now a days the third party softwares like Ext2IIF are frequent in market.
They can easily show the ext2 and ext3 partitions from windows. They even
allow the read write options from windows os, without asking for root password. Is there any security threat in this? How can we hide this?

You said it yourself:

So yes, there is a good security threat. You can either unplug the drive so it's not visible, or lock down the Windows system to make sure those programs aren't installed. This isn't a linux question, really, it's more of a Windows issue. If Windows is booted, that's the 'master' OS...any disks attached to it are at the mercy of the OS and whatever tools it has.

That said, you could encrypt the Linux drive(s), and not provide the passwords, unless you (or authorized folks), wanted to access that data, but I'm not even sure that encrypted linux drives can be accessed under Windows, even with the passwords.

I'm not sure about encrypted drives either, but from my own personally experience, LVM's couldn't be accessed no matter what I tried.

Don't tell windows is master. None of these external tools is made by Microsoft.

would it help if you deleted them from the partition table? I've done this before to hide data. if the partitions are not in the partition table windows and it's tools have no way of knowing it's even there. of course you have to redo your partition table before you could get at your data again.

I think deleting partition information is a bit extreme

Encryption should be what he wants.
