This page will guide you through the how to configure your GitLab Self-Managed instance to use Data Theorem’s SAST scanning without sharing your code with Data Theorem. It will create AWS resources to run a container-based SAST scanner provided by Data Theorem. The SAST scan results will be visible in the Data Theorem portal

Installation

Requirements

• The GitLab installation must be exposed to the internet

• The user following these instructions must have administrator permissions to the GitLab instance

• AWS Account with Admin Access

Step 1: Create A Data Theorem App In GitLab

Start with creating the GitLab application for the Data Theorem integration:

• Log into the GitLab instance

• Open “Applications” in the Admin Area

• Create a new instance-wide application with the following settings

  • Name: Data Theorem SAST

  • Redirect URI: https://www.securetheorem.com/gitlab-integration/onboarding

  • Trusted: checked

  • Confidential: checked

  • Scopes: api and read_repository

• Clicking “Save application”

• Securely make a note of the Application ID, Secret, and instance URL (from the address bar of your browser). You will need to enter these values in the next step

Step 2: Create AWS Resources

Open the AWS CloudFormation Quick Create Link you received from Data Theorem, and sign in the AWS account where you want the SAST scanning resources to be created.

Create a new system hook with the following settings:

• URL: Copy/Paste the CloudFormation Stack Output named GitLabSystemHookUrl

• Secret Token: Copy/Paste the CloudFormation Stack Output named GitLabSystemHookSecret

Paste the values for the GitLab App Id, Gitlab App Secret

Step 3: Configuring The GitLab System Hook

The system hook will notify the GitLab integration of changes to any of the repositories present in the GitLab integration.

Configuration steps:

• Log into the GitLab instance

• Navigate to “System Hooks” in the Admin Area

• Create a new system hook with the following settings:

  • URL: Copy/Paste the CloudFormation Stack Output named GitLabSystemHookUrl

  • Secret Token: Copy/Paste the CloudFormation Stack Output named GitLabSystemHookSecret

  • Trigger:

    • Check “Repository update events”

    • Check “Merge request events”

  • Check “SSL verification”

Step 4: Update The GitLab App OAuth Redirect URI

• Open “Applications” in the Admin Area

• Edit the Data Theorem SAST application and update the Redirect URI setting

  • Redirect URI: Copy/Paste the CloudFormation Stack Output named GitLabOAuthRedirectUri
