Lind

Lind is a single-process sandbox that provides an option to safely execute programs and control its resource (network, file, memory, cpu, etc.) usage at the process granularity. Lind executes applications in an isolated environment from the rest of the applications in the system, and thus limits the damage of bugs or security flaws in the application.

For high level documentation, please go to the main documentation for the project.

Lind is currently a work in progress, please bear with us while features are being implemented.

Building with Docker

Base and pre-built docker images for the SDK toolchain can be fetched from the Docker Hub Lind repository at securesystemslab/lind with docker pull securesystemslab/lind.

You can either make run or start the container yourself using:

docker pull securesystemslab/lind
docker run --privileged --ipc=host --init --cap-add=SYS_PTRACE -it securesystemslab/lind /bin/bash

The --privileged option is so that /proc is writable, the --ipc=host option is needed to avoid mounting /dev/shm with noexec (NaCl needs to be able to execute mmap()'d sections of /dev/shm) and the --cap-add=SYS_PTRACE allows debugging with applications that use ptrace() such as gdb.
