name	mapping-mitre-attack-techniques
description	Maps observed adversary behaviors, security alerts, and detection rules to MITRE ATT&CK techniques and sub-techniques to quantify detection coverage and guide control prioritization. Use when building an ATT&CK-based coverage heatmap, tagging SIEM alerts with technique IDs, aligning security controls to adversary playbooks, or reporting threat exposure to executives. Activates for requests involving ATT&CK Navigator, Sigma rules, MITRE D3FEND, or coverage gap analysis.

Mapping Mitre Attack Techniques

Overview

Cybersecurity skill for mapping mitre attack techniques. Follows industry best practices and security standards.

When to Use

Trigger phrases:

• "mapping mitre attack techniques"
• "Generating an ATT&CK coverage heatmap to show which techniques your detection st"
• "Tagging existing SIEM use cases or Sigma rules with ATT&CK technique IDs for str"
• "Aligning your security program roadmap to specific adversary groups known to tar"

Use this skill when:

• Generating an ATT&CK coverage heatmap to show which techniques your detection stack addresses
• Tagging existing SIEM use cases or Sigma rules with ATT&CK technique IDs for structured reporting
• Aligning your security program roadmap to specific adversary groups known to target your sector

Do not use this skill for real-time incident triage — ATT&CK mapping is an analytical activity best performed post-detection or during threat hunting planning.

When NOT to Use

• When you lack proper authorization for testing
• For production systems without change management
• When the task requires legal or compliance expertise beyond technical scope

Prerequisites

• Access to MITRE ATT&CK knowledge base (https://attack.mitre.org) or local ATT&CK STIX data bundle
• ATT&CK Navigator web app or local installation (https://mitre-attack.github.io/attack-navigator/)
• Inventory of existing detection rules (Sigma, Splunk, Sentinel KQL) to assess current coverage
• ATT&CK Python library: pip install mitreattack-python

Workflow

# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs(text: str) -> :
     {k: re.findall(v, text)  k, v  IOC_PATTERNS.items()}
