Trivy

Trivy (tri pronounced like trigger, vy pronounced like envy) is a simple and comprehensive vulnerability scanner for containers and other artifacts. A software vulnerability is a glitch, flaw, or weakness present in the software or in an Operating System. Trivy detects vulnerabilities of OS packages (Alpine, RHEL, CentOS, etc.) and application dependencies (Bundler, Composer, npm, yarn, etc.). Trivy is easy to use. Just install the binary and you're ready to scan. All you need to do for scanning is to specify a target such as an image name of the container.

To learn more about the Trivy scanner itself visit on Trivy's GitHub Repository.

Deployment

The Trivy scanType can be deployed via helm:

helm upgrade --install trivy secureCodeBox/trivy

Scanner Configuration

The following security scan configuration example are based on the [Trivy Documentation], please take a look at the original documentation for more configuration examples.

• Filter the vulnerabilities by severities trivy image --severity HIGH,CRITICAL ruby:2.4.0
• Filter the vulnerabilities by type (os or library) trivy image --vuln-type os ruby:2.4.0
• Skip update of vulnerability DB: trivy image --skip-update python:3.4-alpine3.9
• Ignore unfixed vulnerabilities:trivy image --ignore-unfixed ruby:2.4.0 By default, Trivy also detects unpatched/unfixed vulnerabilities. This means you can't fix these vulnerabilities even if you update all packages. If you would like to ignore them, use the --ignore-unfixed option.
