SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill empowers security analysts to proactively identify and investigate potential threats within their environment by leveraging powerful Sigma detection rules and established threat hunting methodologies.

Core Features & Use Cases

  • Sigma Rule Application: Utilize a comprehensive set of pre-defined Sigma rules to detect suspicious activities across various log sources (process creation, network connections, file events, registry modifications).
  • Threat Investigation Workflow: Follow a structured approach for triaging alerts, gathering contextual information, performing timeline analysis, and implementing containment strategies.
  • Rule Conversion: Convert Sigma rules to formats compatible with popular SIEM platforms like Splunk, Elasticsearch, and Microsoft Sentinel.
  • Use Case: When a security alert fires indicating potential malware execution, use this Skill to apply relevant Sigma rules, analyze the associated process and network logs, and determine the scope and impact of the incident.

Quick Start

Use the threat-hunting skill to analyze suspicious PowerShell commands using Sigma rules.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I convert Sigma rules for threat hunting into Splunk or Elasticsearch queries?▼

To convert Sigma rules for threat hunting into Splunk or Elasticsearch queries, this Skill provides structured workflows to translate detection rules into formats compatible with popular SIEM platforms like Splunk, Elasticsearch, and Microsoft Sentinel.

What is the best way to investigate suspicious PowerShell commands using Sigma detection rules?▼

The best way to investigate suspicious PowerShell commands using Sigma detection rules is to apply this Skill's threat hunting workflows to analyze associated process creation and network connection logs, determining the alert's scope and impact.

How does threat hunting with Sigma rules map to the MITRE ATT&CK framework?▼

Threat hunting with Sigma rules maps to the MITRE ATT&CK framework by applying pre-defined detection rules across various log sources to identify suspicious activities, requiring an understanding of MITRE ATT&CK techniques and common security event logging.

Can I use this Sigma rule workflow for incident response triage and containment?▼

Yes, you can use this Sigma rule workflow for incident response triage and containment. It facilitates a structured investigation approach to triage alerts, gather contextual information, perform timeline analysis, and implement containment strategies.

Do I need prior SIEM integration experience to apply Sigma rules for proactive threat detection?▼

You need understanding of Sigma rule syntax, the MITRE ATT&CK framework, and common security event logging to apply Sigma rules for proactive threat detection, rather than specific prior SIEM integration experience, though it benefits SOCs and security analysts.

What log sources are supported when applying Sigma rules for security analysis?▼

When applying Sigma rules for security analysis, supported log sources include process creation, network connections, file events, and registry modifications to help security analysts proactively identify and investigate potential threats.
