Security hardening for Harness CI

Harness offers features that help you build securely with Harness CI. Combine these features with known industry best practices.

The information is targeted at Harness CI. It is not a comprehensive explanation of all security features and capabilities throughout all Harness products.

Access control​

Harness RBAC helps you control access to your Harness account, organizations, and projects. For authentication, Harness supports SSO and 2FA log-in methods, as well as SAML authentication through various IDPs.

Branch protection and PR checks​

Failed CI pipelines don't inherently block PR merges. Harness can send pipeline statuses to your PRs, but you must configure branch protections and checks (such as protection rules, CODEOWNERS, linting, and other checks or restrictions) in your source control provider.

SLSA​

With Harness CI, you can use the Harness Software Supply Chain Assurance (SSCA) module to generate, manage, store, and enforce SBOM and SLSA Provenance.

You can also run scripts in Run steps to generate SBOM and SLSA Provenance, and then upload those artifacts.

Secrets​

Store tokens, passwords, and other sensitive data as secrets and then use expressions to reference secrets in your pipelines. For example, you can use an expression as the value for a variable:

APP_STORE_PASSWORD=<+secrets.getValue("my_app_store_password_secret")>

When you use secrets and variables in your CI pipelines, it is important to understand how those secrets appear in build logs. For example, secrets in Run step output variables are exposed in logs. For information about secrets masking and sanitization, go to:

Tokens and keys​

Harness APIs use Harness API keys and tokens to authenticate requests. Make sure to create tokens with the appropriate permission scopes. Tokens inherit permissions from the account used to create them. For more information, go to Manage API keys.

You can store tokens and keys from non-Harness providers as secrets in Harness. Harness provides information about required permissions for third-party tokens and keys when relevant, such as authentication credentials for Git connectors; however, this is limited to the permissions necessary for successful integration with Harness.

For information about creating keys/tokens for a specific provider or tool, refer to the documentation for that provider or tool.

Network security​

For network security and private networking, Harness offers features such as:

OIDC​

You can use OpenID Connect (OIDC) with Harness CI.

With Harness Cloud, you can leverage the OIDC connectivity mode in your GCP connectors. You can then use OIDC-enabled GCP connectors in GCP-related steps, such as the Build and Push to GAR step. You can also Configure OIDC with GCP WIF for builds on Harness Cloud.

OIDC is also available in other areas of Harness, such as in the platform-agnostic Kubernetes cluster connector, and in other Harness modules.
