SIEM Use Case Logic

Overview

This repository contains comprehensive SIEM (Security Information and Event Management) use case logic, categorized by security domains. Each use case includes pseudocode to detect various security threats, aiding in building an effective security monitoring system.

Purpose

These use cases help security professionals develop effective SIEM detection rules, providing a structured approach to:

• Detecting cyber threats across different security domains
• Enhancing security operations and incident response
• Aligning SIEM rules with frameworks like MITRE ATT&CK

How to Use

Setting Up

1. Clone the repository:

   git clone https://github.com/your-repo/SIEM-Use-Cases.git

2. Navigate to the repository:

   cd SIEM-Use-Cases

Implementing Use Cases

1. Choose the relevant category based on your SIEM needs.
2. Review the pseudocode and detection logic in the corresponding .md file.
3. Convert the logic into detection rules for your SIEM platform (Splunk, ELK, Sentinel, QRadar, etc.).
4. Customize the detection thresholds and parameters to fit your environment.
5. Test and validate the rules in a controlled environment before deploying them in production.

Continuous Improvement

• Regularly update the threat detection rules based on new intelligence.
• Integrate MITRE ATT&CK techniques for enhanced threat mapping.
• Monitor false positives and false negatives to fine-tune detection logic.
• Collaborate with the security team to improve detection efficiency.
