Checkmarx

Overview

Checkmarx is an automated application security platform that checks source code for security vulnerabilities and compliance issues. Integrate Cortex with Checkmarx to drive insight into the vulnerabilities detected on your entities.

This integration is supported for Checkmarx Static Application Security Testing (SAST).

How to configure Checkmarx with Cortex

Prerequisites

Before getting started, create a user with access to the sast_rest_api scope.

If you're using a self-hosted instance of Checkmarx, you'll need to verify that your Cortex instance is able to reach the Checkmarx instance. We route our requests through a static IP address. Reach out to support at [e-mail] to receive details about our static IP. If you're unable to directly allowlist our static IP, you can route requests through a secondary proxy in your network that has this IP allowlisted and have that proxy route traffic to your Checkmarx instance.

Configure the integration in Cortex

1. In Cortex, navigate to the Checkmarx settings page:

   1. In Cortex, click your avatar in the lower left corner, then click Settings.

   2. Under "Integrations", click Checkmarx.

2. Click Add configuration.

3. Configure the Checkmarx integration form:

   • Username and Password: Enter the username and password for the user with access to sast_rest_api.

   • Host: Enter the full URL of your Checkmarx instance.

4. Click Save.

How to connect Cortex entities to Checkmarx

Discovery

By default, Cortex will use your associated Git repository (e.g. repo-name) or the service tag as the "best guess" for the Checkmarx project name.

If your repository and entity names don’t cleanly match the Checkmarx CxSAST project names, or if you have multiple Checkmarx projects for a service, you can add a Checkmarx project ID (recommended) or a Checkmarx project name in the Cortex entity descriptor.

Editing the entity descriptor

We recommend using the project ID as it is a unique identifier across projects.

Example using project IDs:

x-cortex-checkmarx:
  projects:
    - projectId: 1234
    - projectId: 2345

Example using both project IDs and names:

x-cortex-checkmarx:
  projects:
    - projectName: My Cool Project
    - projectId: 1234

Expected results

Entity pages

Once the integration is established, vulnerabilities pulled from Checkmarx will be available for each entity in the Code and Security block in the Overview tab.

While viewing an entity, click Code & security > Checkmarx. On this page, view the number of vulnerabilities per severity and a link directly to your Checkmarx instance.

Scorecards and CQL

With the Checkmarx integration, you can create Scorecard rules and write CQL queries based on Checkmarx details.

See more examples in the CQL Explorer in Cortex.

Check if Checkmarx project is set

Check if entity has a registered Checkmarx project in its entity descriptor. If there is a Checkmarx project name, we will try and make sure that the project exists in Checkmarx.

Definition: checkmarx (==/!=) null: Boolean

Example

In a Scorecard, you can write a rule to check whether an entity has a Checkmarx project set:

checkmarx != null

Checkmarx scan risk

Get the maximum scan risk among the entity's project's latest scans

Definition: checkmarx.sastScanRisk(): Number

Example

In a Scorecard, you can write a rule to verify that an entity has no Checkmarx projects where the latest scan risk is higher than 35:

checkmarx.sastScanRisk() < 35

Number of Checkmarx vulnerabilities

Get the count of all vulnerabilities for an entity's Checkmarx project's last scan

Definition: checkmarx.numOfVulnerabilities(): Number

Example

In a Scorecard, you can write a rule to verify that an entity has no vulnerabilities with a severity of HIGH:

checkmarx.numOfVulnerabilities(severity=["High"]) < 1

Verify that an entity has less than 5 vulnerabilities total:

checkmarx.numOfVulnerabilities() < 5

FAQs and troubleshooting

Does Cortex support integrating with Checkmarx One?

No, Cortex does not currently support Checkmarx one. Only Checkmarx SAST is supported for this integration.
