Implementing a Scheduled Code Scan on AWS CodeCommit with Snyk: A Step-by-Step Guide

As a developer, you understand the importance of keeping your code secure and up-to-date. With the rise of open-source components, it’s becoming increasingly challenging to ensure that your code is free from vulnerabilities. That’s where Snyk comes in – a popular tool for identifying and fixing vulnerabilities in your code. In this article, we’ll show you how to implement a scheduled code scan on AWS CodeCommit using Snyk, providing you with a comprehensive guide to get you started.

What is Snyk?

Snyk is an open-source security platform that helps you identify and fix vulnerabilities in your code. It supports a wide range of programming languages, including Java, Node.js, Python, and more. Snyk integrates seamlessly with popular development tools like GitHub, GitLab, and Bitbucket, making it an ideal choice for developers who want to ensure the security of their code.

What is AWS CodeCommit?

AWS CodeCommit is a fully managed version control service that makes it easy to collaborate on software development projects. It provides a secure, scalable, and highly available platform for storing and managing your code. With CodeCommit, you can easily track changes, collaborate with team members, and maintain multiple versions of your code.

Why Implement a Scheduled Code Scan with Snyk on AWS CodeCommit?

Implementing a scheduled code scan with Snyk on AWS CodeCommit provides several benefits, including:

• Enhanced Security: Identify and fix vulnerabilities in your code before they become a security risk.
• Improved Code Quality: Get insights into your code’s dependencies and ensure that they are up-to-date and secure.
• Streamlined Development: Automate code scanning and focus on writing secure code instead of manually reviewing dependencies.
• Compliance: Meet compliance requirements by ensuring that your code meets industry standards for security and quality.

Prerequisites

To implement a scheduled code scan with Snyk on AWS CodeCommit, you’ll need the following:

1. An AWS account with access to CodeCommit.
2. A Snyk account with a valid API token.
3. A CodeCommit repository with your code.
4. A basic understanding of AWS Lambda functions and Amazon CloudWatch Events.

Step 1: Create a Snyk API Token

To create a Snyk API token, follow these steps:

1. Log in to your Snyk account and navigate to the Settings page.
2. Click on API Tokens and then click on New Token.
3. Enter a name for your token and select the Read permission.
4. Click on Create Token to generate the API token.

Note: Keep your API token secure and do not share it with anyone.

Step 2: Create an AWS Lambda Function

To create an AWS Lambda function, follow these steps:

1. Log in to your AWS account and navigate to the Lambda dashboard.
2. Click on Create function and then select Author from scratch.
3. Choose Node.js 14.x as the runtime and give your function a name (e.g., snyk-code-scan).
4. Set the handler to index.handler and set the environment variable SNYK_API_TOKEN to your Snyk API token.
5. Click on Create function to create the Lambda function.

Note: Make sure to update the handler and environment variable accordingly.

Step 3: Create an Amazon CloudWatch Event

To create an Amazon CloudWatch Event, follow these steps:

1. Log in to your AWS account and navigate to the CloudWatch dashboard.
2. Click on Events and then click on Create event.
3. Choose Schedule as the event source and set the schedule to your desired frequency (e.g., daily at 2 AM).
4. Set the target to your Lambda function (created in Step 2) and click on Create event.

Note: Make sure to update the schedule and target accordingly.

Step 4: Configure the Lambda Function

To configure the Lambda function, follow these steps:

1. Log in to your AWS account and navigate to the Lambda dashboard.
2. Click on your Lambda function and navigate to the Configuration tab.
3. Update the Function code with the following code:

exports.handler = async (event) => {
  const snyk = require('snyk');
  const git = require('simple-git')();

  // Set the Snyk API token
  snyk.config.set('token', process.env.SNYK_API_TOKEN);

  // Clone the CodeCommit repository
  const repoUrl = 'https://git-codecommit.us-east-1.amazonaws.com/v1/repos/your-repo-name';
  await git.clone(repoUrl);

  // Run the Snyk code scan
  const result = await snyk.test('.');

  // Print the result
  console.log(result);

  // Return a success response
  return {
    statusCode: 200,
    body: JSON.stringify('Code scan completed successfully!'),
  };
};

Note: Update the repoUrl with your CodeCommit repository URL.

Step 5: Test the Scheduled Code Scan

To test the scheduled code scan, follow these steps:

1. Wait for the scheduled event to trigger the Lambda function.
2. Check the Lambda function logs to ensure that the code scan was successful.
3. Review the results of the code scan to identify any vulnerabilities in your code.

Note: Make sure to update the Lambda function logs accordingly.
