Introduction:

One of the most important pillars of a well-architected AWS framework is security. To ensure the safety and integrity of your production environment, it’s critical to follow AWS security best practices, organized by service. This guide outlines 26 key practices to help prevent security issues and protect your infrastructure

AWS IAM Best Practices:

Avoid Full “*” Admin Privileges: IAM policies should never grant full administrative access.

Do Not Attach IAM Policies to Users:
Use groups and roles instead of attaching policies directly to IAM users.

Rotate Access Keys Every 90 Days:
Ensure regular key rotation for IAM users to minimize security risks.
Remove Root User Access Keys: Never create access keys for the root user.

Enable MFA for All IAM Users:
All users with console access should have MFA enabled for added security.

Enable Hardware MFA for the Root User:
Secure the root user account with hardware-based MFA.

Enforce Strong Password Policies:
Configure strong password policies for all IAM users.

Remove Unused IAM Credentials:
Regularly audit and remove inactive user credentials.

Amazon S3 Security Best Practices:

Enable S3 Block Public Access:
Prevent accidental public exposure by enabling this setting globally.

Enable Server-Side Encryption for Buckets:
Protect data at rest by enforcing encryption.

Enforce Block Public Access at the Bucket Level:
Make sure individual buckets also block public access.

AWS CloudTrail Best Practices:

Enable Multi-Region CloudTrail:
Track and log activities across multiple regions for comprehensive monitoring.

Enable Encryption at Rest:
Ensure that CloudTrail logs are encrypted for secure storage.

Enable Log File Validation:
Add an additional layer of integrity by validating CloudTrail log files.

AWS Config Best Practices:

Enable AWS Config:
Monitor your AWS resources continuously with AWS Config to track configuration changes.

Amazon EC2 Best Practices:

Encrypt EBS Volumes:
Ensure all attached EBS volumes are encrypted at rest.

Enable VPC Flow Logs:
Capture network flow logs for monitoring and security analysis.

Restrict VPC Default Security Group:
Do not allow unrestricted inbound or outbound traffic in the default security group.

Enable Default EBS Encryption:
Ensure encryption by default for new EBS volumes.

AWS DMS Best Practices:

Keep DMS Replication Instances Private:
Do not expose AWS Database Migration Service instances to the public.

Amazon EBS Best Practices:

Keep EBS Snapshots Private:
Ensure snapshots are private and not restorable by unauthorized entities.

Amazon OpenSearch Best Practices:

Enable Encryption for OpenSearch:
Encrypt Elasticsearch domains to protect data at rest.

Amazon SageMaker Best Practices:

Disable Direct Internet Access for Notebooks:
Isolate SageMaker notebook instances by disabling direct internet access.

AWS Lambda Best Practices:

Use Supported Runtimes:
Always use Lambda runtimes that are actively supported by AWS.

AWS KMS Best Practices:

Avoid Unintentional Key Deletion: Ensure that AWS KMS keys are properly managed to avoid accidental deletion.

Amazon GuardDuty Best Practices:

Enable GuardDuty: Leverage GuardDuty for continuous threat detection and monitoring in your AWS environment.

Conclusion:

Before you start building your AWS environment, ensure that it is secure, reliable, and well-architected by following these AWS security best practices. By adopting these recommendations, you can prevent unnecessary security incidents and protect your production environment from potential threats.
