CycloneDX
Generating
Trivy can generate SBOM in the CycloneDX format. Note that XML format is not supported at the moment.
You can use the regular subcommands (like image, fs and rootfs) and specify cyclonedx with the --format option.
CycloneDX can represent either or both SBOM or BOV.
By default, --format cyclonedx represents SBOM and doesn't include vulnerabilities in the CycloneDX output.
$ trivy image --format cyclonedx --output result.json alpine:3.15
2022-07-19T07:47:27.624Z INFO "--format cyclonedx" disables security checks. Specify "--security-checks vuln" explicitly if you want to include vulnerabilities in the CycloneDX report.
Result
$ cat result.json | jq .

If you want to include vulnerabilities, you can enable vulnerability scanning via --security-checks vuln.
$ trivy image --security-checks vuln --format cyclonedx --output result.json alpine:3.15
Scanning
Trivy can take CycloneDX as an input and scan for vulnerabilities.
To scan SBOM, you can use the sbom subcommand and pass the path to your CycloneDX report.
$ trivy sbom /path/to/cyclonedx.json
cyclonedx.json (alpine 3.7.1)

Note
If you want to generate a CycloneDX report from a CycloneDX input, please be aware that the output stores references to your original CycloneDX report and contains only detected vulnerabilities, not components. The report is called BOV.
