Indicator Extraction Configuration

This page describes the configuration structures employed by maec-to-stix for indicator extraction and how they may be modified by users in order to customize the behavior of the utility.

Overview

Extracting indicators from malware is a process that requires fine tuning based on a number of internal or external factors. As such, maec-to-stix supports the customization of its behavior in terms of extracting indicators from MAEC data. This customization can be performed at multiple levels, both high-level and granular.

In terms of high-level customization options, maec-to-stix offers the ability to specify:

  • Whether to extract indicators for some predefined system activity OR based on a user-specified granular configuration.
  • For extracting indicators based on predefined system activity, the particular type of activity to extract indicators for.
    • E.g., file system, Windows registry, network, etc.
  • Whether to normalize the indicator output to make it relatively system independent.

With regards to granular customization options, maec-to-stix offers the ability to specify:

  • The particular MAEC action types to attempt to extract indicators from.
    • E.g., create file, create registry key, etc.
  • The particular CybOX object types to attempt to extract indicators from, as well as the specific properties of each object type that are allowable for usage in an indicator.

Configuration Structures

The maec-to-stix configuration structures are stored in JSON files and have two distinct levels of granularity. Details of how to edit and use the high-level and granular configuration files, as well as information about the structures of the files themselves can be found at:
