How to Install AWS Security Hub

AWS Security Hub is a comprehensive security service that provides centralized visibility into the security state of your AWS environment. It helps aggregate, organize, and prioritize security findings from various AWS services (e.g., AWS GuardDuty, AWS Inspector, and AWS Macie) as well as from third-party security solutions.

To install and configure AWS Security Hub programmatically, you can use AWS CLI commands, AWS SDKs, or AWS CloudFormation templates. Below are the steps and code snippets to help automate the installation and configuration of AWS Security Hub using the AWS CLI and CloudFormation.

1. Prerequisites

Before starting, make sure you have the following:

• AWS CLI installed and configured with your credentials.
• IAM Permissions: Ensure you have the necessary IAM permissions to create and configure AWS Security Hub (e.g., securityhub:EnableSecurityHub, securityhub:DescribeHub, etc.).

2. Enable AWS Security Hub Using AWS CLI

To enable AWS Security Hub, you can use the AWS CLI. Here’s how you can enable it programmatically.

Step 1: Enable AWS Security Hub

Use the following AWS CLI command to enable AWS Security Hub in your AWS account:

aws securityhub enable-security-hub

This command enables AWS Security Hub in your current AWS region. You should see a confirmation output indicating that the service has been enabled.

Step 2: Enable Security Standards

You can enable various security standards such as AWS Foundational Security Best Practices, CIS AWS Foundations Benchmark, or others. For example, to enable the AWS Foundational Security Best Practices:

aws securityhub enable-security-standards --standards-arn arn:aws:securityhub:us-east-1::standards/aws-foundational-security-best-practices/v/1.0.0

This enables the AWS Foundational Security Best Practices standard in AWS Security Hub.

Step 3: Enable AWS Config Integration (Optional)

If you want to integrate AWS Config with Security Hub to collect configuration and compliance data:

aws securityhub enable-import-findings-from-securityhub --import-findings

3. Set Up AWS Security Hub Using AWS SDK

You can also use AWS SDKs (e.g., Python boto3) to automate the process of enabling and configuring AWS Security Hub.

Step 1: Install the AWS SDK (boto3 for Python)

If you’re using Python, install the boto3 library:

pip install boto3

Step 2: Enable AWS Security Hub using boto3

Here’s an example using Python and boto3 to enable AWS Security Hub:

import boto3

# Create a SecurityHub client
client = boto3.client('securityhub')

# Enable AWS Security Hub
response = client.enable_security_hub()

# Print the response
print(response)

This script uses the AWS SDK for Python to enable Security Hub in your AWS account.

Step 3: Enable Security Standards using boto3

Here’s how you can enable the AWS Foundational Security Best Practices standard programmatically:

# Enable AWS Foundational Security Best Practices
response = client.enable_security_standards(
    StandardsArn='arn:aws:securityhub:us-east-1::standards/aws-foundational-security-best-practices/v/1.0.0'
)

print(response)

This script enables the AWS Foundational Security Best Practices standard for security assessments.

4. Set Up AWS Security Hub Using CloudFormation

You can also enable and configure AWS Security Hub via AWS CloudFormation. Below is an example CloudFormation template to enable Security Hub.

Step 1: CloudFormation Template to Enable Security Hub

AWSTemplateFormatVersion: '2010-09-09'
Resources:
  EnableSecurityHub:
    Type: 'AWS::SecurityHub::Hub'
    Properties:
      Tags:
        Name: 'SecurityHubSetup'

This CloudFormation template enables Security Hub in the AWS environment.

Step 2: Deploy CloudFormation Template Using AWS CLI

Once you have your CloudFormation template (securityhub-setup.yaml), you can deploy it using the following command:

aws cloudformation create-stack --stack-name EnableSecurityHubStack --template-body file://securityhub-setup.yaml

This will create a CloudFormation stack that enables AWS Security Hub.

5. Integrate Findings from Other AWS Services

Once you have enabled Security Hub, you can start aggregating findings from other services like AWS GuardDuty, AWS Macie, and AWS Inspector.

Step 1: Enable GuardDuty Findings in Security Hub

If you have Amazon GuardDuty enabled, you can automatically send findings from GuardDuty to Security Hub:

aws securityhub enable-import-findings-from-source --source-type "GuardDuty"

Step 2: Enable Macie Findings in Security Hub

If you are using Amazon Macie for sensitive data discovery, you can send Macie findings to Security Hub:

aws securityhub enable-import-findings-from-source --source-type "Macie"

6. View Security Hub Findings

Once everything is set up, you can view the security findings using the AWS Management Console or by querying Security Hub using AWS CLI or boto3.

For example, to list findings using AWS CLI:

aws securityhub get-findings

Or using boto3:

# Retrieve findings from Security Hub
response = client.get_findings()

# Print findings
for finding in response['Findings']:
    print(finding)

7. Enable Security Hub in Multiple Regions

If you want to enable AWS Security Hub across multiple regions, you need to manually enable it in each region or use automation scripts to deploy across your regions.

For example, with AWS CLI, you can set the --region flag for each region:

aws securityhub enable-security-hub --region us-west-2
aws securityhub enable-security-hub --region eu-west-1
