Rule: EC2 Instances Should Be in a VPC
This rule emphasizes the need for EC2 instances to be configured within a Virtual Private Cloud (VPC).

| Severity | ✔ High |
Rule: EC2 instances should be in a VPC for HIPAA compliance.
Description:
The rule is to ensure that all EC2 instances within the infrastructure are deployed within a Virtual Private Cloud (VPC) to meet the requirements of the Health Insurance Portability and Accountability Act (HIPAA) compliance. HIPAA is a regulatory framework that mandates data security and privacy of sensitive healthcare information.
By placing EC2 instances within a VPC, organizations can apply additional security measures and control network traffic to protect sensitive data from unauthorized access or breaches. VPC provides isolated network spaces, enabling the segregation of different application tiers, and provides tools for enhanced network security configurations.
Troubleshooting Steps:
- 1.Validate if the EC2 instances are currently residing within a VPC.
- 2.Ensure that the VPC settings align with the requirements outlined in the HIPAA compliance standards.
- 3.If the EC2 instances are not within a VPC, follow the remediation steps below.
Remediation Steps:
- 1.Launch a new VPC or identify an existing VPC within the AWS account.
- 2.Create or adjust the subnet configuration within the VPC to meet the specific requirements of HIPAA compliance.
- 3.Assign security groups to the EC2 instances within the VPC to control inbound and outbound network traffic.
- 4.Ensure that the Network Access Control Lists (NACLs) are properly configured to restrict access to the EC2 instances.
- 5.Implement security measures such as encryption at rest and in transit to safeguard sensitive data.
- 6.Regularly monitor and review VPC logs and security group configurations to identify any potential vulnerabilities.
- 7.Validate the connectivity and accessibility of the EC2 instances within the VPC to ensure proper functionality.
- 8.Perform regular audits to ensure ongoing adherence to HIPAA compliance requirements.
