SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables security teams to write high-quality Suricata rules with automated syntax validation, best-practices enforcement, and integrated PCAP testing, reducing manual trial-and-error and deployment risk.

Core Features & Use Cases

Automated rule writing that adheres to best practices and avoids deprecated keywords.
Syntax validation with suricata-language-server to catch errors before deployment.
PCAP-based testing to verify the rule detects intended traffic and minimizes false positives in Suricata deployments.
Use Case: A SOC analyst drafts a new rule for unusual HTTP user-agent patterns and validates it against a sample PCAP to confirm detection.

Quick Start

Describe the detection goal and I will draft a rule, validate it with suricata-language-server, and, if you provide a PCAP, test it against real traffic.

FAQPage Schema

How do I write production-ready Suricata rules with automated syntax validation?▼

To write production-ready Suricata rules with syntax validation, describe your detection goal and the tool drafts the rule, validates it via suricata-language-server, and enforces best practices to prevent deployment errors.

Can I test Suricata signatures against real traffic to verify detections?▼

Yes, you can test Suricata signatures against real traffic by providing a PCAP file. The tool runs PCAP-based testing to verify your rule detects the intended traffic and minimizes false positives before deployment.

What metadata fields are required for Suricata rule creation best practices?▼

Required metadata fields for Suricata rule creation best practices include msg, sid, rev, created_at, and updated_at. The tool automatically ensures these fields are populated correctly to maintain production-grade quality.

How do I avoid deprecated keywords when writing Suricata rules?▼

To avoid deprecated keywords when writing Suricata rules, the tool automatically enforces best practices during rule generation. It validates syntax using suricata-language-server to catch deprecated keywords before deployment.

Does suricata-language-server validation catch syntax errors before deploying rules?▼

Yes, suricata-language-server validation catches syntax errors before deploying rules. The tool integrates this validation process to ensure your Suricata rules are production-ready and free of syntax issues.

What is the best way to validate unusual HTTP user-agent pattern detections in Suricata?▼

The best way to validate unusual HTTP user-agent pattern detections in Suricata is to draft the rule and test it against a sample PCAP. This confirms the rule matches intended traffic and reduces false positives.
