What is Securing a multi-account AWS environment?

Securing a multi-account AWS environment is a critical aspect of cloud engineering services as it helps ensure the safety and privacy of the data and resources hosted on AWS. A multi-account environment refers to the use of multiple AWS accounts to isolate different environments, such as development, testing, and production, to reduce the risk of accidental resource modification or deletion.

Securing a multi-account AWS environment involves implementing various security controls, such as:

• Identity and Access Management (IAM) – Implementing IAM best practices, such as the principle of least privilege, to limit access to AWS resources to only authorized users and services.

• Network Security – Implementing network security controls such as security groups, network ACLs, and VPCs to control the ingress and egress traffic between resources and the internet.

• Encryption – Using encryption for data at rest and in transit, and implementing AWS Key Management Service (KMS) to manage encryption keys.

• Monitoring and Logging – Implementing a centralized logging and monitoring solution to track and identify any unusual activities and events.

• Security Automation – Using AWS security automation tools such as AWS Config, AWS Security Hub, and AWS GuardDuty to detect and remediate security threats in real-time.

• Compliance – Ensuring that the AWS environment is compliant with industry-specific regulations and standards such as HIPAA, PCI-DSS, and GDPR.

By implementing these security controls, a multi-account AWS environment can be better protected against security threats and data breaches, enabling cloud engineering services to operate in a secure and reliable manner.

Problem Statement

As a cloud services provider, the top 3 inquiries from large enterprises with workloads running on AWS are:

• How can I secure my multi-account AWS environment?
• How can we make sure that all accounts are complying with compliance and auditing requirements?
• How can we complete this quickly, all at once, rather than in pieces?

Even though large organisations with numerous AWS accounts have guidelines for new AWS implementations, managing and monitoring all the accounts at once is inefficient, time-consuming, and prone to security risks.

Solution

AWS Control Tower is the best solution to provision, manage, govern, and secure a multi-AWS account environment, even though there are more traditional methods of securing AWS environments using AWS IAM, Service Catalog, Config, and AWS Organizations.

Using pre-approved account configurations, Control Tower’s Account factory automates the provisioning of new AWS accounts. A landing zone that is based on best-practices blueprints is automatically created by the control tower, and guardrails are used to enable governance. The landing zone is a multi-account baseline with sound architecture that adheres to the AWS well-architected framework. Guardrails put governance regulations for operations, compliance, and security into effect.

Organizations can use Control Tower to:

• Easily create well-designed multi-account environments; and provide federated access using AWS SSO.
• Use VPC to implement network configurations.
• Create workflows for creating accounts using AWS Service Catalog
• Ensure adherence to guardrails-set rules.
• Detect security vulnerabilities automatically.

Benefits

• Beneficial for continuously growing enterprises, where there will be new additions to AWS accounts progressively.
• Helpful for large businesses with a diverse mix of engineering, operations, and development teams
• Gives a step-by-step process to customise the build and automate the creation of an AWS Landing Zone
• Prevents the use of resources in a manner inconsistent with the organization’s policies.
• Guardrails are a high-level rule in Control Tower’s AWS Config rules and helps detecting non-conformance with previously provisioned resources.
• Provides a dashboard for quick access to provisioned accounts and reports on the detective and preventive guardrails that are activated on your accounts.
• Compliance Reports detailing any resources that violate policies that have been enabled by guardrails.

In conclusion, securing a multi-account AWS environment is crucial for ensuring the confidentiality, integrity, and availability of your organization’s data and resources. By implementing proper security measures such as access controls, monitoring, and automation, you can significantly reduce the risk of security breaches and data loss.
