Nessus step configuration

Scan application instances with Nessus.

You can scan your application instances and ingest results from Nessus.

Workflow descriptions

Orchestration/extraction workflows

This workflow applies to scanner integrations that support orchestratedScan or dataLoad scan modes.

1. Add a Build or Security stage to your pipeline.

2. If you're scanning a code repository, set up your codebase.

3. Add a Custom Scan step.

4. Review the Important notes for Custom Scan steps for additional requirements and relevant information.

   If you're setting up a scan on a Kubernetes or Docker build infrastructure, you need to add a Docker-in-Docker background step to the stage.

5. Add the relevant key:value pairs to Settings.

Ingestion workflows

This workflow applies to scanner integrations that support Ingestion mode.

1. Add a Build or Security stage to your pipeline.

2. Add a Run step and set it up to save your scan results to a shared folder.

   For more information, go to Run an ingestion scan in an STO Pipeline.

3. Add a Custom Scan step.

4. Review the Important notes for Custom Scan steps for additional requirements and relevant information.

5. Add the relevant key:value pairs to Settings.

Custom Scan step settings for Nessus scans in STO

Scanner settings

These settings are required for most scanners. For more information, go to the reference for the scanner integration you're setting up.

• Product name

• Scan type

• Policy type

• Product config name

Product name

The scanner name. This is required for all Custom Scan steps.

Key

product_name

Value

nessus

Scan type

The target type to scan.

Key

scan_type

Value

instance

Policy type

The scan mode to use.

Key

policy_type

Value

orchestratedScan

ingestionOnly

Product config name

Key

product_config_name

Value

nessus-web-application

Target and variant

Every Custom Scan step needs a target and baseline.

• Target name

• Target variant

Target name

Key

target_name

Value

A user-defined label for the code repository, container, application, or configuration to scan. Specify a unique, descriptive name. This makes it much easier to navigate your scan results in the STO UI.

Target variant

Key

target_variant

Value

A user-defined label for the branch, tag, or other target variant to scan.

Instance

These settings apply to Custom Scan steps when both of these conditions are true:

1. The policy_type is orchestratedScan or dataLoad.

2. The scan_type is instance.

• Instance domain

• Instance path

• Instance protocol

• Instance port

• Instance username

• Instance password

Instance domain

Key

instance_domain

Value

Domain of the application instance to scan. You can include the full path to the app in this field, or split the full path between the instance_domain and the instance_path settings. Example: https://myapp.io/portal/us

Instance path

Key

instance_path

Value

Path to append to the application instance domain, if you're splitting the full path between the instance_domain and the instance_path settings. For example, you might specify the domain as https://myapp.io and the path as /portal/us.

Instance protocol

Key

instance_protocol

Value

One of the following: HTTPS is the default.

HTTPS

HTTP

Instance port

Key

instance_port

Value

The TCP port used by the scanned app.

Instance username

Key

instance_username

Value

The username for authenticating with the scanned app.

Instance password

Key

instance_password

Value

You should create a Harness text secret with your encrypted password and reference the secret using the format <+secrets.getValue("container-access-id")>. For more information, go to Add and reference text secrets.

Product access

These settings are available to access your Nessus instance when policy_type is orchestratedScan.

You should create Harness text secrets for your encrypted passwords/tokens and reference them using the format <+secrets.getValue("my-access-token")>.

Product access keys

product_domain

product_access_id

product_access_token

product_policy_id

product_scanner_id

product_template_uuid

Ingestion file

This setting applies to Custom Scan steps when the policy_type is ingestionOnly.

Key

ingestion_file

Value

The path to your scan results when running an Ingestion scan, for example /shared/scan_results/myscan.latest.sarif.

• The data file must be in a supported format for the scanner.

• The data file must be accessible to the scan step. It's good practice to save your scan results to a shared path in your stage. In the visual editor, go to the stage where you're running the scan. Then go to Overview > Shared Paths. You can also add the path to the YAML stage definition like this:

      - stage:
        spec:
          sharedPaths:
            - /shared/scan_results

Fail on Severity

If the scan finds any vulnerability with the specified severity level or higher, the pipeline fails automatically. NONE means do not fail on severity.

For more information, go to:

• STO workflows for blocking builds and PRs.

• Exemptions to override Fail on Severity thresholds for specific issues in STO

Key

fail_on_severity

Value

CRITICAL

MEDIUM

LOW

INFO

NONE
