The value is expected at the beginning of the field's content (strings and regular expressions) The value is matched anywhere in the field (strings and regular expressions) Modifier comparison between pySigma and sigmac Modifier PySigma brings a number of additional features compared to sigmac, as well as some changes. We recommend using the "Cookie Cutter Template" and reviewing the existing backends listed in the "Related Projects" section of this README. The creation of a backend has become much easier with pySigma. my_awesome_pipelines import pipeline_1, pipeline_2įinally, submit a pull request to the pySigma-plugin-directory and update the version compatibility of your backend plugin with pySigma.īy following these steps, your backend plugin will be compatible with newer versions of pySigma and sigma-cli, allowing for autodiscovery and migration of backend plugins. In the sigma/pipelines/my_awesome_pipelines/_init_.py file, add a pipelines global variable that lists the available pipelines: from. my_awesome_backend import MyAwesomeBackend ![]() In the sigma/backends/my_awesome_backend/_init_.py file, add a backends global variable that references the backend class: from. To address this issue, plugin developers should make the following changes to their backends: However, some backends may not function with the updated sigma-cli version. Recently, the backend plugin autodiscovery functionality has been added, eliminating the need for manual registration of plugins in sigma-cli. Autodiscovery and Migration of Backend Plugins ![]() Examples: pip install pysigmaĭocumentation with some usage examples can be found here. To start using pySigma, install it using your python package manager of choice. See the Related Projects section below to get an overview. Rule for log data models are separated into dedicated projects to keep pySigma itself slim and It is a replacementįor the legacy Sigma toolchain (sigmac) with a much cleaner design and is almost fully tested.īackends for support of conversion into query languages and processing pipelines for transforming By default, the alert is triggered at 15 minutes past every hour, 10 minutes after the search job is scheduled to run.PySigma is a python library that parses and converts Sigma rules into queries. Use the same frequency for alerts and make sure alerts are triggered after the search job is complete, taking into account the search execution time.
