GitHub releases PyPI Scrutinizer Code Quality code test coverage CircleCI

ospd is a base class for scanner wrappers which share the same communication protocol: OSP (Open Scanner Protocol). OSP creates a unified interface for different security scanners and makes their control flow and scan results consistently available under the central Greenbone Vulnerability Manager service.

OSP is similar in many ways to GMP (Greenbone Management Protocol): XML-based, stateless and non-permanent connection.

The design supports wrapping arbitrary scanners with same protocol OSP, sharing the core daemon options while adding scanner specific parameters and options.

ospd requires Python >= 3.7 along with the following libraries:

- python3-paramiko

- python3-lxml

- python3-defusedxml

Install using pip

You can install ospd from the Python Package Index using pip:

python3 -m pip install ospd

Alternatively download or clone this repository and install the latest development version:

python3 -m pip install .

How to write your own OSP Scanner Wrapper

As a core you need to derive from the class OSPDaemon from See the documentation there for the single steps to establish the full wrapper.

See the file doc/ about how to register a OSP scanner at the Greenbone Vulnerability Manager which will automatically establish a full GUI integration for the Greenbone Security Assistant (GSA).

Your contributions are highly appreciated. Please create a pull request on GitHub. For bigger changes, please discuss it first in the issues.

For development you should use poetry to keep you python packages separated in different environments. First install poetry via pip

python3 -m pip install --user poetry

Afterwards run

poetry install

in the checkout directory of ospd (the directory containing the pyproject.toml file) to install all dependencies including the packages only required for development.

The ospd repository uses autohooks to apply linting and auto formatting via git hooks. Please ensure the git hooks are active.

poetry install
poetry run autohooks activate --force
