How to Write Share Platform SIEM Agnostic Detection Content
Security Information and Event Management (SIEM) is a system that collects, analyzes, and correlates data from various sources to detect and respond to security incidents. However, not all SIEM platforms are compatible with each other, and some may have different features or capabilities. This can make it challenging to write detection content that works across different SIEM platforms.
In this article, we will share some tips and best practices on how to write share platform SIEM agnostic detection content. This means that the detection content can be easily adapted or ported to different SIEM platforms without losing its effectiveness or accuracy.
What is Share Platform SIEM Agnostic Detection Content
Share platform SIEM agnostic detection content is a type of detection content that is designed to be independent of any specific SIEM platform. It can be written in a generic or standard format that can be easily translated or converted to the native format of any SIEM platform. For example, it can be written in a common query language (CQL) that can be mapped to the specific query language of each SIEM platform.
Share platform SIEM agnostic detection content has several benefits, such as:
It can reduce the time and effort required to write and maintain detection content for multiple SIEM platforms.
It can increase the consistency and quality of detection content across different SIEM platforms.
It can facilitate the sharing and collaboration of detection content among security analysts and researchers.
It can enable the reuse and repurposing of detection content for different use cases and scenarios.
How to Write Share Platform SIEM Agnostic Detection Content
Writing share platform SIEM agnostic detection content requires some planning and preparation. Here are some steps that you can follow:
Define the objective and scope of the detection content. What are you trying to detect What are the indicators of compromise (IOCs) or behaviors of interest What are the data sources and types that you need
Research and validate the detection logic. How can you express the detection logic in a generic or standard way What are the common or universal elements or attributes that you can use How can you test and verify the accuracy and effectiveness of the detection logic
Write the detection content in a common query language (CQL). Choose a CQL that is widely used or supported by different SIEM platforms, such as SQL, SPL, EQL, etc. Use clear and descriptive names for variables, fields, tables, etc. Use comments and annotations to explain the logic and assumptions behind the detection content.
Document and share the detection content. Provide metadata and context for the detection content, such as name, description, author, date, version, etc. Include references and sources for the detection logic, such as threat intelligence reports, research papers, blog posts, etc. Publish or distribute the detection content in a format that is easy to access and consume by different SIEM platforms, such as JSON, XML, CSV, etc.
Conclusion
Writing share platform SIEM agnostic detection content can help you improve your security posture and efficiency by leveraging the power of different SIEM platforms. By following some tips and best practices, you can create detection content that is generic, standard, consistent, and reusable across different SIEM platforms. aa16f39245
