We now require that Debian users install the `python3` and `python3-pip` packages. This change lets the Python code search for `libclang.so`, which can be located in different directories, depending on version, and is not found by default otherwise.

# Sandboxed API

## What is Sandboxed API?
|
|
|
|
The Sandboxed API project (**SAPI**) aims to make sandboxing of C/C++ libraries
|
|
less burdensome: after initial setup of security policies and generation of
|
|
library interfaces, an almost-identical stub API is generated (using a
|
|
[template-based programming variable hierarchy system](sandboxed_api/docs/variables.md)),
|
|
transparently forwarding calls using a custom RPC layer to the real library
|
|
running inside a sandboxed environment.
|
|
|
|
Additionally, each SAPI library utilizes a tightly defined security policy, in
|
|
contrast to the typical sandboxed project, where security policies must cover the total
|
|
syscall/resource footprint of all utilized libraries.
|
|
|
|
|
|
## Intended audience
|
|
|
|
SAPI is designed to help you sandbox only a part of binary. That is, a library
|
|
or some other code with an unknown security posture.
|
|
|
|
See [Sandboxing Code](sandboxed_api/docs/sandbox-overview.md) to make sure this is the type of
|
|
sandboxing you are looking for.
|
|
|
|
## How does it work?
|
|
|
|
Navigate to our [How it works](sandboxed_api/docs/howitworks.md) page.
|
|
|
|
|
|
## Motivation
|
|
|
|
Sandboxes available for use in Google required additional implementation work
|
|
with each new instance of project which was intended to be sandboxed, even if
|
|
it reused the same software library. Sandbox security policies and other
|
|
restrictions applied to the sandboxed process had to be reimplemented each
|
|
time, and data exchange mechanisms between trusted and untrusted parts of
|
|
the code had to be designed from the scratch.
|
|
|
|
While designing the Sandboxed API project, our goal was to make this process
|
|
easy and straightforward. Our working motto is: **Sandbox once, use anywhere**.
|
|
|
|
|
|
## Is it proven technology?
|
|
|
|
The project has been designed, developed and is maintained by members of
|
|
the Google Sandbox Team. It also uses our field-tested
|
|
[Sandbox 2](sandboxed_api/sandbox2/README.md).
|
|
|
|
Currently, many internal projects are already using SAPI to isolate
|
|
their production workloads. You can read more about them in the
|
|
[Examples](sandboxed_api/docs/examples.md) section.
|
|
|
|
We've also prepared some more example SAPI implementations for your reference.
|
|
|
|
|
|
## Quick Start
|
|
|
|
Install the required dependencies, this assumes you are running Debian 10
|
|
"Buster":
|
|
|
|
```bash
|
|
echo "deb http://storage.googleapis.com/bazel-apt stable jdk1.8" | \
|
|
sudo tee /etc/apt/sources.list.d/bazel.list
|
|
wget -qO - https://bazel.build/bazel-release.pub.gpg | sudo apt-key add -
|
|
sudo apt-get update
|
|
sudo apt-get install -qy build-essential linux-libc-dev bazel python3 \
|
|
python3-pip libclang-7-dev
|
|
pip3 install clang
|
|
```
|
|
|
|
Clone and run the build:
|
|
```bash
|
|
git clone https://github.com/google/sandboxed-api && cd sandboxed-api
|
|
bazel build ...
|
|
```
|
|
|
|
Try out one of the [examples](sandboxed_api/docs/examples.md):
|
|
```bash
|
|
bazel run //sandboxed_api/examples/stringop:main_stringop
|
|
```
|
|
|
|
There are also a more detailed instructions that should help you
|
|
**[getting started with SAPI](sandboxed_api/docs/getting-started.md)**.
