# Lynis: audit the execution environment



Audit the execution environment.



## 1. Run the example



[Download the Lynis example](https://www.security.run/docs/examples/lynis.zip). Extract it, install `httpx`, set your API URL and token, then run `python client.py`. The client uploads the included inputs, submits the command, and saves the result under `results/RUN_ID`.



## 2. Check the result



Read report.dat and audit.log for checks performed inside the disposable environment.



Read the native exit code and cleanup status printed by the client. [Read results and save reports](https://www.security.run/docs/visibility.html) explains the returned files.



## 3. Use your own inputs



Edit `example.json` to change the command arguments, requested outputs or deadline. Replace the files under `inputs/` with your own data, keeping the staged paths aligned with the command. The client creates the artifact IDs for you; illustrative IDs shown here must not be copied into a live request.



The example uses supplied files or the disposable execution environment. Nothing from the environment carries into a later run unless you request and reuse its output.



Qualified version: `3.1.4-1`. Commands: `lynis`.



- The audit describes this executor; root-only checks are limited by the unprivileged runtime.



Inspect `GET /v1/tools/lynis` for the current installed version and readiness. The published snapshot has 1 functional case(s), plus timeout and cancellation checks. These examples demonstrate the native path; other flags and inputs are supported within the tool’s runtime limits.
