Introduction

In our previous blogs, we have discussed the AWS Shield. We are moving forward with the same discussion but with a different perspective. We shall be discussing the AWS Security Hub. Nevertheless, let's move to the topic.

AWS Security Hub

It provides a comprehensive view of your security state in AWS. It helps you to check your environment against the security industry standards. It collects the data from AWS accounts, services, and supported third-party partner products, enabling you to analyze your security trends and identify the highest priority security threats.

Working of Security Hub

AWS Security Hub works in the following ways

  1. Security Hub Console
  2. Security Hub API

When a user enables the Security Hub, It begins to consume, aggregate, organize and prioritize the results from AWS services that you have enabled. 

Security Hub also generates its findings by constantly running automated security checks based on AWS best practices and supported industry standards. 

Security Hub correlates and consolidates the findings across providers to help you to prioritize the most significant results. Users can create insights in Security Hub. Insight is a collection of conclusions merged when applying a Group by the filter. 

Terminology and concepts

  1. Account: An essential Amazon Web Services (AWS) account consists of the user's AWS resource. Users can sign in to an AWS account to enable the Security Hub. An account can invite another user to allow Security hub and become associated with that account.
     
  2.  Administrator Account: An account can become an administrator if it invites other accounts or becomes associated with it in Security Hub. When those accounts accept the invitation, they become account members, and the user asking them becomes their administrator account. An organization management account designates the account as the Security Hub administrator account. The Security Hub can enable any organization account as a member account.
     
  3. Aggregation Region: It is a region that allows you to view security results from multiple Regions in a single search. The aggregation Region can be the Region from which you view and handle effects.
     
  4. Archived Findings: The finding provider believes that the finding is no longer needed. The record state is separated from the workflow status.
     
  5. Control: Countermeasures are required for an information system or an organization to protect the confidentiality, integrity, and availability of its information which meets a set of defined security requirements.

Data Protection in AWS Security Hub

We recommend using AWS Identity and Access Management to secure AWS account credentials and create individual user accounts for data protection purposes (IAM). As a result, each user is only granted the permissions required to carry out their job duties. We also advise you to secure your data in the following ways:

  • With each account, use multi-factor authentication (MFA).
  • To communicate with AWS resources, use SSL/TLS. TLS 1.2 or later is recommended.
  • Configure AWS CloudTrail to log API and user activity.
  • Use AWS encryption solutions in conjunction with all AWS service default security controls.
  • Use advanced managed security services, such as Amazon Macie, to help discover and secure personal data stored in Amazon S3.

We strongly advise against entering confidential or sensitive information, such as email addresses, into tags or free-form fields like the Name field. This includes using the console, API, AWS CLI, or AWS SDKs to interact with Security Hub or other AWS services. Any information entered into tags, or free-form name fields may be used for billing or diagnostic logs. If you provide a URL to an external server, we highly suggest against including credentials in the URL to validate your request to that server.

Security Hub is a service that has multiple tenants. Security Hub encrypts data at rest and data in transit between component services to ensure data security.

AWS Identity and Access Management for AWS Security Hub

AWS Identity and Access Management(IAM) is an AWS service that helps an administrator secure the control access to AWS resources. The IAM administrator controls who will be authenticated and authorized to use Security Hub resources. 

Audience

Service user– If you use the Security Hub service to do your job, your administrator will provide you with the necessary credentials and permissions. You may require additional permissions as you use more Security Hub features to complete your tasks. Understanding how access is managed will assist you in requesting the appropriate authorizations from your administrator. 

Service administrator – You probably have full access to Security Hub if you are in charge of Security Hub resources at your company. It is your responsibility to decide which Security Hub features and help your employees have access. You must then submit requests to your IAM administrator to change your service users' permissions. Examine the information on this page to grasp the fundamental concepts of IAM. See How AWS Security Hub works with IAM for more details on how your company can use IAM with Security Hub.

IAM administrator – If you're an IAM administrator, you might be interested in learning more about writing policies to manage Security Hub access.

Authenticating with Identities

You must be signed in to AWS as the AWS account admin account, an IAM user, or assuming an IAM role. You can also sign in using your company's single sign-on authentication or Google or Facebook. In these cases, your administrator has already configured indicates a person using IAM roles. When you use credentials from another company to access AWS, you indirectly assume a role.

Frequently Asked Questions

What is a Security Hub, and how does it work?

Security Hub collects data from AWS accounts and services supported by third-party partner products. It helps the user analyze your security trends.
 

Why do the users need to enable AWS config?

Security Hub strongly recommends that the user must enable AWS Organizations. It manages your accounts and streamlines the process of managing member accounts.

What is centrally AWS Security Hub?

AWS Security Hub gives you a comprehensive view to manage the user's high-priority security alerts and compliance status across the AWS accounts.

Conclusions
