Anchore Enterprise Feeds
Anchore Enterprise Feeds is an On-Premises service that supplies operating system and application eco-system vulnerability data and package data for consumption by the Anchore Policy Engine. The Policy Engine uses this data for finding vulnerabilities and evaluating policies. For more information about how Anchore manages feed data, see Feeds Overview.
Anchore maintains a public index of Grype databases built and published daily at https://toolbox-data.anchore.io/grype/databases/listing.json for use by all. Anchore Enterprise Feeds offers the following benefits over those pre-built grype databases:
- Run Anchore Enterprise in Air-Gapped mode.
- Granular control and configuration over feed data due to On-Premises installation. Configure how often the data from external sources is synced, enable/disable individual data providers responsible for processing normalized data. Access to an Anchore-curated dataset for suppressing known false positive vulnerability matches
Anchore Enterprise Feeds have three high-level components:
- Drivers – Communicate with upstream sources and fetch data and normalize it for Anchore.
- Database – Stores the current state of the normalized data for use by Anchore.
- API – Serves the data to clients, supporting update-only fetches.
A driver downloads raw data from an external source and normalizes it. Each driver outputs normalized data for one of the four feed types - (os) vulnerabilities, packages, nvd or third party feeds.
- Drivers responsible for operating system package vulnerabilities gather raw data from the respective os resources listed below.
- Package drivers process the official list of packages maintained by NPM and RubyGems organizations.
- The nvdv2 driver processes CVEs from the NIST database, and supplies normalized data that is used for matching non-os packages such as Java, Python, NPM, GEM, NuGet.
All drivers except for the package drivers are enabled by default. The service has configuration toggles to enable/disable each driver individually and tuning driver specific settings.
anchore_match_exclusions feed requires a specific license. Please contact Anchore Support for details.
Normalized vulnerability and package data is persisted in the database. In addition, the execution state and updates to the data set are tracked in the database.
