This feature might change without preserving backwards compatibility.
Trivy’s compliance flag lets you curate a specific set of checks into a report. In a typical Trivy scan, there are hundreds of different checks for many different components and configurations, but sometimes you already know which specific checks you are interested in. Often this would be an industry accepted set of checks such as CIS, or some vendor specific guideline, or your own organization policy that you want to comply with. These are all possible using the flexible compliance infrastructure that's built into Trivy. Compliance reports are defined as simple YAML documents that select checks to include in the report.
Compliance report is currently supported in the following targets (trivy sub-commands):
--compliance flag to the command line, and set it's value to desired report.
trivy k8s cluster --compliance k8s-nsa (see below for built-in and custom reports)
The following flags are compatible with
--compliance flag and allows customizing it's output:
||shows a summary of the results. for every control shows the number of failed checks.|
||shows fully detailed results. for every control shows where it failed and why.|
||shows results in textual table format (good for human readability).|
||shows results in json format (good for machine readability).|
Trivy has a number of built-in compliance reports that you can asses right out of the box.
to specify a built-in compliance report, select it by ID like
trivy --compliance <compliance_id>.
For the list of built-in compliance reports, please see the relevant section:
You can create your own custom compliance report. A compliance report is a simple YAML document in the following format:
spec: id: "k8s-myreport" # report unique identifier. this should not container spaces. title: "My custom Kubernetes report" # report title. Any one-line title. description: "Describe your report" # description of the report. Any text. relatedResources : - https://some.url # useful references. URLs only. version: "1.0" # spec version (string) controls: - name: "Non-root containers" # Name for the control (appears in the report as is). Any one-line name. description: 'Check that container is not running as root' # Description (appears in the report as is). Any text. id: "1.0" # control identifier (string) checks: # list of existing Trivy checks that define the control - id: AVD-KSV-0012 # check ID. Must start with `AVD-` or `CVE-` severity: "MEDIUM" # Severity for the control (note that checks severity isn't used) - name: "Immutable container file systems" description: 'Check that container root file system is immutable' id: "1.1" checks: - id: AVD-KSV-0014 severity: "LOW"
The check id field (
controls.checks.id) is referring to existing check by it's "AVD ID". This AVD ID is easily located in the check's source code metadata header, or by browsing Aqua vulnerability DB, specifically in the Misconfigurations and Vulnerabilities sections.
Once you have a compliance spec, you can select it by file path:
trivy --compliance @</path/to/compliance.yaml> (note the
@ indicating file path instead of report id).
