Open Asset Model

The Open Asset Model (OAM) redefines the understanding of an attack surface. Shifting the paradigm away from narrow, internet infrastructure-focused collection, the OAM framework broadens its scope to include both physical and digital assets. This approach delivers a realistic view of assets and their lesser-known associations, utilizing adversarial tactics to gain visibility into potential risks and attack vectors that might otherwise be overlooked.


Key Benefits

  • Deep Attack Surface Intelligence: Identifies both physical and digital assets, moving beyond IT infrastructure.
  • Standardized Asset Framework: Ensures consistency in asset classification, facilitating efficient data exchange and streamlined analysis.
  • Cyclic Discovery: Recursively approaches data exploration, leveraging each finding to dynamically expand the target scope.
  • Community-Driven: Developed and continuously refined by security experts within the OWASP Amass ecosystem.
  • Risk Mapping: Exposes hidden attack vectors by mapping asset relationships and tracking their changes over time.

Open Asset Taxonomy

The Open Asset Model organizes assets into Contact, Registration, Infrastructure, People, Organization, and Fingerprint classes, bridging the relationships within and across these specifications.
