WinJail

What is WinJail?

What is jail/chroot?

Virtually all applications work in the same file space and folder called mounted file systems. For UNIX-based platforms, the root point is named "/". In Windows, we have many roots for each disk drive separately, but in all cases there is common logical space in the file system.

The basic idea of chroot is to use subtree (such as C:/TEMP) as the mutual root of the unit, but only for specific applications. For example, this "Foo" application uses many files at the root of drive C: In the chroot, it will continue to logically use these files; but physically all files will be placed in the C:\TEMP folder, for example, instead of C:\.

What is WinJail?

WinJail is the full implementation of chroot, with additional features such as the "copy on write" mechanism applied to chroot'ed files, additional registry-based chroot, and more.

WinJail has templates that can be applied to all applications launched from a specific folder or to applications with the exact name "Foo.exe"; Therefore, these templates can be configured to apply it immediately when the appropriate program starts, even without reconfiguring the starting point for that program.

Designed for effective host administration, WinJail provides the way to manage Windows impersonation techniques in conjunction with templates; Each service or application can now be limited with some credentials defined in the template. For example, all "Foo" programs can be chrooted specifically, but only if user "John" starts it.

In addition, WinJail advertises technology called " copy on write ". To work with the chroot'ed application, you need to copy all the contents of the system to the strings, including windows, if the system also runs chroot'ed. But forget about it with WinJail! When accessing these chrooted files for the first time, they will be automatically copied to the prison. To ensure that private data will not be copied, WinJail provides the ability to mark certain folders as "private"; These folders will not be copied to the strings.

For example, the "Foo" program needs to use these system files from the Windows directory. Therefore, in the classic way, you need to prepare the environment with chroot for this case: you need to copy these files manually. But with the CoW technique with WinJail, this can be done automatically and only when needed.

WinJail Possibilities:

Generate specific applications with arrest

Manage templates for apps

Provide separation by user/group in templates

Prepare the prison environment with a user-friendly interface

With "copy on write" folders, make managing your chroot environment quick and easy to use.
