What's supported in Harness STO

This topic lists the supported STO features and integrations to scan your code repositories, container images, and other targets for security vulnerabilities. Harness STO is supported on the following platforms:

• Harness SaaS
• Harness Self-Managed Enterprise Edition (SMP)
• Harness SMP in offline environments

Harness SaaS

Scanners

Scanner categories

The following list shows the scan types that STO supports:

• SAST (Static Application Security Testing) scans a code repository and identifies known vulnerabilities in open-source and proprietary code.
• SCA (Software Composition Analysis) scans a code repository and identifies known vulnerabilities in open-source libraries and packages used by the code.
• DAST (Dynamic Application Security Testing) scans a running application for vulnerabilties by simulating a malicious external actor exploiting known vulnerabilties.
• Container Scanning identifies vulnerabilities in container images.

Harness STO scanner support

If you use a scanner that isn't listed in the following table, you can still ingest your scan results into STO. For a full description of the workflow, go to Ingest Results from Custom or Unsupported Scanners.

Scanner binaries used in STO container images

Harness maintains and updates a container image for every scanner supported by STO. The following table lists the binaries and versions used for the most popular scanners.

Twistlock	twistcli	30.01.152
Whitesource	java -jar /opt/whitesource/wss-unified-agent.jar	23.5.2.1

Data ingestion

Harness Security Testing Orchestration integrates with multiple scanners and targets. Different types of scan approaches can be done on each scanner-target combination:

• Orchestrated (orchestratedScan) Scans are fully orchestrated. A Security step in the Harness pipeline orchestrates a scan and then normalizes and compresses the results.
• Extraction (dataLoad) Scans are partially orchestrated. The Security step pulls scan results from an external SaaS service and then normalizes and compresses the data.
• Ingestion (ingestionOnly) Scans are not orchestrated. The Security step ingests results from a previous scan (for a scan run in a previous step), and then normalizes and compresses the results.

In addition to ingesting scan data in the external scanner's native format, STO steps can also ingest data in SARIF and Harness Custom JSON format.

Build infrastructure

STO support by CI build infrastructure type

STO uses CI build infrastructures to orchestrate scans and ingest issues. The following table shows STO support for each infrastructure type.

Operating System	Architecture	Harness Cloud	Docker	VMs	Kubernetes
Linux	amd64	✅	✅	✅	✅
Linux	arm64	✅	✅	✅	✅
Windows	amd64	Roadmap	❌	Roadmap	❌
MacOS	amd64	Roadmap	Roadmap	Roadmap	❌
MacOS	arm64	❌	❌	❌	❌

Approvals / Ticketing

Harness STO supports the following features for generating notifications and stopping pipelines in response to detected vulnerabilities:

• Each Security step has a Fail on Severity setting that causes a pipeline build to fail if a Security Scan step detects one or more issues with the specified severity (Critical, High, Medium, etc.). You can also create exemptions ("Ignore rules") for specific issues to override this behavior.

• You can also governance policies and security scan results to stop pipelines automatically.

• You can set up STO to (create Jira tickets automatically for issues detected during an STO build.

• You can also generate automated emails for detected issues.

Governance

Harness Policy As Code uses Open Policy Agent (OPA) as the central service to store and enforce policies for the different entities and processes across the Harness platform.

You can centrally define and store policies and then select where (which entities) and when (which events) they will be applied.

Currently, you can define and store policies directly in the OPA service in Harness.

Soon, you will be able to use remote Git or other repos (e.g. OCI-compatible registries) to define and store the policies used in Harness.

• Harness Policy As Code overview
• Harness Policy As Code quickstart
• Add a Policy step to a pipeline

Harness Self-Managed Enterprise Edition (SMP)

All STO features supported in Harness SaaS are also supported in Self-Managed Enterprise Edition with the following exceptions:

• Custom dashboards
• Harness AI Development Assistant (AIDA) for STO
• You cannot run SaaS-based scans if there is no connectivity between Harness and the external SaaS environment.

Harness SMP in offline environments

If you're running Harness Self-Managed Enterprise Edition in an offline environment, note the following:

• SaaS-based scanners require connectivity between Harness and the external SaaS environment. This means that you cannot run SaaS-based scans in offline environments.

• All STO scanners are supported in both Harness SaaS and Self-Managed Enterprise Edition. Harness regularly updates the container images it uses to run STO scans. If you're running STO in an offline environment, Harness recommends that you download your STO images regularly to ensure that your scanners are up-to-date. For more information, go to Configure STO to Download Images from a Private Registry.
