Use Case 10 - Threat Intelligence Sharing

Use Case 10 - Threat Intelligence Sharing

Nota importada desde Inbox durante consolidacion bulk.

Resumen

This use case establishes and maintains collaborative channels with relevant partners for proactive exchange of cyber threat information, enhancing situational awareness and enabling proactive defense. It defines comprehensive sharing policies, partner identification strategies, secure sharing mechanisms, and classification scopes per partner type. The framework supports both technical stakeholders (SOC, IR, VM) and non-technical stakeholders (business leaders, risk management, compliance, legal) using STIX/TAXII and MISP as core sharing platforms.

Objetivo

Establish and maintain collaborative channels with relevant partners to proactively exchange cyber threat information for enhanced situational awareness and proactive defense.

Proceso / Flujo de Trabajo

1. Develop a Comprehensive Sharing Policy

Define clear guidelines for:

  • Types of intelligence to be shared
  • Sharing formats (STIX/TAXII, MISP, etc.)
  • Classification levels and handling procedures
  • Data protection and privacy regulations
  • Reciprocity expectations

2. Identify Strategic Sharing Partners

  • Industry Peers: Companies within the sector facing similar threats.
  • Government Agencies: National, regional or local agencies (e.g., CISA, CERTs, Law Enforcement).
  • Security Vendors: Providers of security solutions and threat data.
  • Information Sharing Groups: Sector-specific ISACs/ISAOs or regional groups.

3. Establish Secure Sharing Mechanisms

  • Trusted Communities/Platforms: Leverage existing sharing platforms or create a dedicated space.
  • Technical Integration: Employ APIs or standard protocols to automate intelligence exchange.
  • Encryption and Access Control: Protect sensitive data in transit and at rest.
