            # `PySigma QRadar AQL`
This is the QRadar AQL backend for [pySigma](https://github.com/SigmaHQ/pySigma) 
which parses and converts [Sigma](https://github.com/SigmaHQ/sigma) Rules into 
QRadar queries in AQL. It consists of a backend and two pipelines as describes below.
The project is using [pySigma_QRadar_base](https://github.com/IBM/pySigma_QRadar_base)
submodule.


# Backend
- QRadarAQL: It provides the package `sigma.backends.QRadarAQL` with the `QRadarAQLBackend` class.

# Pipelines
Further, it contains the following processing pipelines in `sigma.pipelines.QRadarAQL`:
- QRadarAQL_fields_pipeline: Supports only the `Sigma fields` in the [Field Mapping](./README.md#field-mapping).
- QRadarAQL_payload_pipeline: Uses `UTF8(payload)` instead of fields unsupported by the [Field Mapping](./README.md#field-mapping). For unsupported fields, the following value types are not supported–
   * Boolean
   * Null
   * CIDR
   * Regular Expression
   * Numeric Comparison

# Installation

## PyPI
```
pip install ibm-qradar-aql
```

## Sigma plugin

### Sigma CLI
1. install [sigma-cli](https://github.com/SigmaHQ/sigma-cli#Installation)
2. install with Sigma plugins:
```
sigma plugin install ibm-qradar-aql
```

### pySigma
```python
from sigma.plugins import SigmaPluginDirectory

plugins = SigmaPluginDirectory.default_plugin_directory()
plugins.get_plugin_by_id("ibm-qradar-aql").install()
```

## Usage
Convert Sigma rules to AQL by using `ibm-qradar-aql` as backend, and one of `qradar-aql-fields` and `qradar-aql-payload` as pipeline:

### Sigma CLI
```
sigma convert -t ibm-qradar-aql -p <qradar-aql-fields | qradar-aql-payload> <rule path> -o <output file name>
```

#### Input example:
*PLEASE NOTE: you should have `Sigma rules` in your project to use the 
following 
command*
```
sigma convert -t ibm-qradar-aql -p qradar-aql-payload rules/windows/create_remote_thread/create_remote_thread_win_keepass.yml -o output_file.txt
```

#### Output example:
```
['SELECT * FROM events WHERE devicetype=12 AND LOWER("Target Process Path") LIKE \'%\\keepass.exe\'']
```

### pySigma
#### Input example:

```python
from sigma.collection import SigmaCollection
from sigma.backends.QRadarAQL import QRadarAQLBackend
from sigma.pipelines.QRadarAQL import QRadarAQL_fields_pipeline, QRadarAQL_payload_pipeline

pipeline = QRadarAQL_fields_pipeline  # or QRadarAQL_payload_pipeline
rule = SigmaCollection.from_yaml("""
    logsource:
        product: windows
        category: create_remote_thread
    detection:
        selection:
            TargetImage|endswith: '\KeePass.exe'
        condition: selection
""")
print(QRadarAQLBackend(pipeline()).convert(rule)[0])
```

#### Output example:
```
SELECT * FROM events WHERE devicetype=12 AND LOWER("Target Process Path") LIKE '%\keepass.exe'
```

# Develop

# Mapping Contribution
Pull requests are welcome. After updating the Mapping, please run 
[generate_readme.py](./generate_readme.py) for updating the mapping tables in 
the README file.

### [Field Mapping](./sigma/mapping/fields.py):
#### field mapping from Sigma to AQL
- `field_mapping`: mapping for fields with exact mach from Sigma to AQL
- `host_field_mapping`: mapping for host fields- values with wildcards converts to CIDR
- `unstructured_field_mapping`: mapping for fields that their value is a substring of another field's value- equal sign ('=') will be replaced with 'LIKE' operator
- `unstructured_part_field_mapping`: mapping for fields that are part of another field- equal sign ('=') will be replaced with 'LIKE' operator, and the value transforms to the form '{field}%{value}' 

### Log-Source Mapping:
#### mapping from Sigma log source to AQL device type id
- [aql_log_source_mapping](./sigma/mapping/logsources.py): AQL mapping from 
  device type name to device type id – *PLEASE DO NOT CHANGE THIS MAPPING*
- [aql_service_mapping](./sigma/mapping/services.py): mapping from Sigma 
  services to AQL device type id
- [aql_product_mapping](./sigma/mapping/products.py): mapping from Sigma products 
  to AQL device type id

    "description": "# `PySigma QRadar AQL`\nThis is the QRadar AQL backend for [pySigma](https://github.com/SigmaHQ/pySigma) \nwhich parses and converts [Sigma](https://github.com/SigmaHQ/sigma) Rules into \nQRadar queries in AQL. It consists of a backend and two pipelines as describes below.\nThe project is using [pySigma_QRadar_base](https://github.com/IBM/pySigma_QRadar_base)\nsubmodule.\n\n\n# Backend\n- QRadarAQL: It provides the package `sigma.backends.QRadarAQL` with the `QRadarAQLBackend` class.\n\n# Pipelines\nFurther, it contains the following processing pipelines in `sigma.pipelines.QRadarAQL`:\n- QRadarAQL_fields_pipeline: Supports only the `Sigma fields` in the [Field Mapping](./README.md#field-mapping).\n- QRadarAQL_payload_pipeline: Uses `UTF8(payload)` instead of fields unsupported by the [Field Mapping](./README.md#field-mapping). For unsupported fields, the following value types are not supported\u2013\n   * Boolean\n   * Null\n   * CIDR\n   * Regular Expression\n   * Numeric Comparison\n\n# Installation\n\n## PyPI\n```\npip install ibm-qradar-aql\n```\n\n## Sigma plugin\n\n### Sigma CLI\n1. install [sigma-cli](https://github.com/SigmaHQ/sigma-cli#Installation)\n2. install with Sigma plugins:\n```\nsigma plugin install ibm-qradar-aql\n```\n\n### pySigma\n```python\nfrom sigma.plugins import SigmaPluginDirectory\n\nplugins = SigmaPluginDirectory.default_plugin_directory()\nplugins.get_plugin_by_id(\"ibm-qradar-aql\").install()\n```\n\n## Usage\nConvert Sigma rules to AQL by using `ibm-qradar-aql` as backend, and one of `qradar-aql-fields` and `qradar-aql-payload` as pipeline:\n\n### Sigma CLI\n```\nsigma convert -t ibm-qradar-aql -p <qradar-aql-fields | qradar-aql-payload> <rule path> -o <output file name>\n```\n\n#### Input example:\n*PLEASE NOTE: you should have `Sigma rules` in your project to use the \nfollowing \ncommand*\n```\nsigma convert -t ibm-qradar-aql -p qradar-aql-payload rules/windows/create_remote_thread/create_remote_thread_win_keepass.yml -o output_file.txt\n```\n\n#### Output example:\n```\n['SELECT * FROM events WHERE devicetype=12 AND LOWER(\"Target Process Path\") LIKE \\'%\\\\keepass.exe\\'']\n```\n\n### pySigma\n#### Input example:\n\n```python\nfrom sigma.collection import SigmaCollection\nfrom sigma.backends.QRadarAQL import QRadarAQLBackend\nfrom sigma.pipelines.QRadarAQL import QRadarAQL_fields_pipeline, QRadarAQL_payload_pipeline\n\npipeline = QRadarAQL_fields_pipeline  # or QRadarAQL_payload_pipeline\nrule = SigmaCollection.from_yaml(\"\"\"\n    logsource:\n        product: windows\n        category: create_remote_thread\n    detection:\n        selection:\n            TargetImage|endswith: '\\KeePass.exe'\n        condition: selection\n\"\"\")\nprint(QRadarAQLBackend(pipeline()).convert(rule)[0])\n```\n\n#### Output example:\n```\nSELECT * FROM events WHERE devicetype=12 AND LOWER(\"Target Process Path\") LIKE '%\\keepass.exe'\n```\n\n# Develop\nThis project is using \n[pySigma_QRadar_base](https://github.com/IBM/pySigma_QRadar_base) submodule.\nAfter cloning the project, make sure to update the submodule from the `sigma` directory \nby running:\n```\ngit submodule update --init --recursive\n```\n\n# QRadar Content Packs\n- [Properties Dictionary](https://exchange.xforce.ibmcloud.com/hub/extension/73f46b27280d30a4b8ec4685da391b1c) (required)\n- [Windows Custom
