Security Hub overview in AWS - Mini Project: Build & Apply

Security Hub overview

📖 Scenario: You are working as a cloud security analyst. Your manager wants you to set up AWS Security Hub to get a centralized view of security alerts and compliance status across multiple AWS accounts.This will help your team quickly identify and respond to security issues.

🎯 Goal: Set up a basic AWS Security Hub configuration using Infrastructure as Code (IaC) to enable Security Hub in a single AWS account.You will create the initial resource, configure a setting, and finalize the Security Hub setup.

📋 What You'll Learn

Create a resource block to enable AWS Security Hub

Add a configuration variable to specify the region

Use the main configuration block to enable Security Hub with default standards

Complete the configuration with the required final attribute to activate Security Hub

💡 Why This Matters

🌍 Real World

Security Hub helps organizations monitor and improve their cloud security posture by aggregating security alerts and compliance checks in one place.

💼 Career

Cloud security engineers and architects use Security Hub to maintain compliance and quickly respond to security threats across AWS environments.

1

Create Security Hub resource block

Create a Terraform resource block called aws_securityhub_account to enable Security Hub in your AWS account.

AWS

# Your code here

Hint

This resource enables Security Hub in your AWS account.

2

Add region variable

Add a Terraform variable called region with default value us-east-1 to specify the AWS region for Security Hub.

AWS

resource "aws_securityhub_account" "main" {
}

# Your code here

Hint

Variables help you configure your infrastructure flexibly.

3

Enable Security Hub with default standards

Inside the aws_securityhub_account resource block, add the depends_on attribute with an empty list and enable the default standards by adding the standards_subscription block with standards_arn set to arn:aws:securityhub:::ruleset/cis-aws-foundations-benchmark/v/1.2.0.

AWS

resource "aws_securityhub_account" "main" {
  # Your code here
}

variable "region" {
  type    = string
  default = "us-east-1"
}

Hint

This enables the CIS AWS Foundations Benchmark standard in Security Hub.

4

Finalize Security Hub activation

Add the enable_default_standards attribute set to true inside the aws_securityhub_account resource block to activate Security Hub with default standards.

AWS

resource "aws_securityhub_account" "main" {
  depends_on = []

  standards_subscription {
    standards_arn = "arn:aws:securityhub:::ruleset/cis-aws-foundations-benchmark/v/1.2.0"
  }
  # Your code here
}

variable "region" {
  type    = string
  default = "us-east-1"
}

Hint

This final step activates Security Hub with the default security standards.

Practice

1. What is the main purpose of AWS Security Hub?

easy

A. To manage user permissions

B. To create virtual machines

C. To show all your security alerts in one place

D. To store large amounts of data

Solution

1. Step 1: Understand Security Hub's role

   AWS Security Hub collects and shows security alerts from different services.

2. Step 2: Compare options with Security Hub's function

   Only To show all your security alerts in one place describes showing security alerts in one place, which matches Security Hub's purpose.

3. Final Answer:

   To show all your security alerts in one place -> Option C

4. Quick Check:

   Security Hub = central alert view [OK]

Hint: Security Hub centralizes security alerts [OK]

Common Mistakes:

• Confusing Security Hub with storage services
• Thinking Security Hub manages users
• Assuming it creates virtual machines

2. Which command is used to enable AWS Security Hub in your account?

easy

A. aws securityhub enable-security-hub

B. aws ec2 start-instances

C. aws s3 create-bucket

D. aws iam create-user

Solution

1. Step 1: Identify the command for enabling Security Hub

   The command to enable Security Hub is specific and includes 'securityhub' and 'enable-security-hub'.

2. Step 2: Eliminate unrelated commands

   Other options relate to EC2, S3, and IAM, which are unrelated to enabling Security Hub.

3. Final Answer:

   aws securityhub enable-security-hub -> Option A

4. Quick Check:

   Enable Security Hub = aws securityhub enable-security-hub [OK]

Hint: Enable Security Hub with aws securityhub enable-security-hub [OK]

Common Mistakes:

• Using EC2 or S3 commands by mistake
• Confusing IAM user creation with enabling Security Hub
• Missing the 'securityhub' part in the command

3. After enabling Security Hub, what will you see when you open the Security Hub console?

medium

A. A list of all your security findings from multiple AWS services

B. A dashboard showing your EC2 instance statuses

C. A list of your S3 buckets and their contents

D. A user management panel

Solution

1. Step 1: Understand what Security Hub displays

   Security Hub shows security findings collected from various AWS services in one place.

2. Step 2: Match options with Security Hub's display

   Only A list of all your security findings from multiple AWS services describes a list of security findings, which is what Security Hub shows.

3. Final Answer:

   A list of all your security findings from multiple AWS services -> Option A

4. Quick Check:

   Security Hub console = security findings list [OK]

Hint: Security Hub console shows security findings [OK]

Common Mistakes:

• Confusing Security Hub with EC2 or S3 consoles
• Expecting user management features in Security Hub
• Thinking it shows bucket contents

4. You enabled Security Hub but do not see any findings. What could be the reason?

medium

A. Security Hub is disabled automatically after enabling

B. No integrated AWS services are sending security data to Security Hub

C. You need to create an S3 bucket first

D. Security Hub only works in specific AWS regions

Solution

1. Step 1: Check data sources for Security Hub

   Security Hub shows findings only if integrated services send data to it.

2. Step 2: Evaluate other options

   Security Hub does not disable itself automatically; no S3 bucket is needed; it works in many regions but not limited to one.

3. Final Answer:

   No integrated AWS services are sending security data to Security Hub -> Option B

4. Quick Check:

   No findings = no data sent [OK]

Hint: Check if services send data to Security Hub [OK]

Common Mistakes:

• Assuming Security Hub disables itself
• Thinking S3 bucket is required
• Believing Security Hub is region-limited

5. You want to improve your cloud security by automatically aggregating findings from multiple AWS accounts into one Security Hub dashboard. What should you do?

hard

A. Manually copy findings from each account to a central S3 bucket

B. Create IAM users in each account and share credentials

C. Use EC2 instances to collect and forward security data

D. Enable Security Hub in the master account and invite member accounts to send findings

Solution

1. Step 1: Understand Security Hub multi-account setup

   Security Hub supports a master-member model where a master account aggregates findings from member accounts.

2. Step 2: Evaluate other options for aggregation

   Creating IAM users or manual copying is inefficient and insecure; EC2 instances are not used for this aggregation.

3. Final Answer:

   Enable Security Hub in the master account and invite member accounts to send findings -> Option D

4. Quick Check:

   Multi-account aggregation = master invites members [OK]

Hint: Use master account to aggregate member findings [OK]

Common Mistakes:

• Trying manual copying of findings
• Using IAM users instead of Security Hub invitations
• Relying on EC2 instances for aggregation
