HIPAA compliant cloud backup with Amazon S3 and Iperius Backup



Introduction

In the healthcare sector, protecting patient data is essential. The Health Insurance Portability and Accountability Act ( HIPAA ) standard defines the requirements for the security and privacy of protected health information (PHI). Consequently, those who perform a backup of medical data in the cloud must ensure that the backup is HIPAA compliant – that is, compliant with HIPAA rules in terms of confidentiality, integrity and availability of the data. Amazon S3, the AWS cloud storage service, can be configured to meet these compliance requirements, especially if you operate in the context of AWS HIPAA Eligible Services . In this article we will see how Amazon S3 can be used for a HIPAA compliant cloud backup , illustrating the necessary configurations (such as encryption, logging, access control, versioning, Object Lock, etc.) and why Iperius Backup represents an excellent solution to implement this type of cloud backup in a secure and efficient way.

Amazon S3 and HIPAA Compliance

Amazon S3 is listed as a HIPAA eligible AWS service , which means that it can be used to store protected health information (PHI) as long as appropriate security measures are in place and the AWS shared responsibility model is followed . First, an organization subject to HIPAA must sign the Business Associate Agreement (BAA) with AWS, which is required for AWS to act as a “Business Associate” and manage PHI in a manner compliant with HIPAA rules. It should be noted that compliance is a joint responsibility: AWS guarantees the security of the cloud infrastructure (data centers, hardware, certifications), while it is up to the user to configure and use the services (such as S3) in a compliant manner (application security, access management, encryption configurations, etc.). Below, we list the main configurations and best practices for making an Amazon S3 bucket HIPAA compliant:

  • Business Associate Agreement (BAA) – As mentioned, before uploading health data to AWS, you are required to enter into a BAA with Amazon. This contractual agreement ensures that AWS takes appropriate measures to safeguard your PHI and defines the limits on how AWS can use and disclose your PHI. Only after you have activated an AWS “HIPAA eligible” account (with a signed BAA) can you use S3 for sensitive data in compliance with the regulations.
  • Encryption at Rest and in Transit – HIPAA requires you to implement “all reasonable measures” to protect sensitive data both at rest and in transit . On Amazon S3, you must enable encryption of objects at rest, for example, using server-side encryption (SSE) with AWS-managed keys (SSE-S3) or with the AWS Key Management Service (SSE-KMS). Additionally, you can use client-side encryption to encrypt files before uploading. At the same time, you must ensure that all transfers are made over secure HTTPS/TLS connections , so that data is encrypted in transit. This ensures that you meet HIPAA requirements for protecting data both in cloud storage and during upload/download.
  • Access Control and Private Buckets – A core tenet of HIPAA is the principle of least privilege : only authorized personnel with operational needs should be able to access healthcare data. It is important to configure access to the S3 bucket in a granular manner via IAM policies, granting permissions only to strictly necessary users and services. All other access should be denied. In particular, you should block public access to the bucket (Amazon S3 provides settings to block any ACLs or public policies) and ensure that no objects with PHI are exposed publicly. Additionally, it is recommended not to include sensitive information in bucket names or file/metadata, as these may not be encrypted by the normal S3 encryption mechanisms.
  • Auditing and Activity Logging – HIPAA requires that you keep a record of data access and actions performed on it (an audit trail). In AWS, it is best practice to enable AWS CloudTrail with S3 Event Logging to record all API calls and object accesses in the bucket. CloudTrail lets you know who accessed what data and when, providing a complete log of PHI activity. Additionally, enabling S3 Server Access Logging (bucket access logs) provides detailed logs of every request made to the bucket, including who made the request, when, what action was taken, and the outcome. These logs should be periodically reviewed for anomalous or unauthorized access, in line with HIPAA auditing rules.
  • Versioning and Deletion Protection (Object Lock) – To ensure data integrity and availability, we recommend enabling Versioning on your S3 bucket. Versioning allows you to retain copies of each version of your objects as they are modified or deleted, making it possible to recover data that has been accidentally overwritten or deleted. For compliance and enhanced protection, Amazon S3 also offers the Object Lock feature, which allows you to set an immutability policy (WORM: Write Once Read Many) on your objects. With Object Lock enabled, backup files cannot be deleted or modified for a defined period of time, even by full administrators. This is especially useful for preventing accidental or malicious deletions (e.g. ransomware attacks) and for meeting regulatory requirements that require data to be kept intact for a certain period of time. Note: To use Object Lock on S3, your bucket must have versioning permanently enabled (once Object Lock is enabled, versioning cannot be disabled).
  • Replication and Disaster Recovery – Finally, HIPAA also requires that you ensure the availability of your healthcare data in the event of a disaster or failure. In addition to maintaining off-site backups, you should leverage the capabilities of Amazon S3 to improve resiliency. One strategy is to set up Cross-Region Replication (CRR) of your bucket, which keeps a synchronized copy of your data in another AWS Region, ensuring that you can access your backups even if an entire AWS Region fails. In parallel, you should have a disaster recovery plan that includes procedures for restoring from S3 backups in disaster scenarios. With the combination of versioning, geographic replication, and durable storage of S3, you can meet HIPAA requirements for business continuity and data availability.

How to make a HIPAA compliant cloud backup to S3 with Iperius Backup

Configuring Amazon S3 correctly is essential, but you also need reliable backup software that leverages these configurations and adds additional layers of security. Iperius Backup is an ideal solution for implementing a HIPAA compliant cloud backup to Amazon S3, thanks to its numerous data protection features. Below we highlight the main reasons why Iperius makes it easy to create a HIPAA compliant backup to AWS S3:

  • End-to-end encryption (TLS and AES 256-bit) – Iperius ensures that data travels and remains encrypted. The software uses secure HTTPS/TLS connections for transfer to Amazon S3, preventing interceptions while sending data. In addition, Iperius supports client-side AES 256-bit encryption : files are compressed in ZIP format and encrypted locally before uploading, ensuring that data in the cloud is already protected by a private key (readable only by those who have the password/encryption set). These features allow you to meet the encryption requirements set by HIPAA without complications. In addition, by using a standard ZIP format, Iperius ensures that data is always recoverable.
  • S3 Versioning Support – Iperius Backup integrates seamlessly with Amazon S3 versioning functionality. If the destination bucket has versioning enabled , each backup performed with Iperius will benefit from the automatic maintenance of previous file versions. In practice, even if a backup file is overwritten by a new execution, S3 will retain the previous version (invisible to the user except through recovery tools) allowing a roll-back if necessary. Iperius does not interfere with this mechanism, indeed it allows the administrator to maintain multiple restore points over time without risk of losing historical data.

  • Immutable backups with Object Lock – One of the most advanced features of Iperius is the ability to create immutable backups using Amazon S3 Object Lock. Iperius natively supports the retention and lock mode settings on uploaded objects: it is therefore possible to configure WORM (Write Once Read Many) cloud backup software easily and automatically. When creating the backup job, the user can enable Object Lock and define an immutable retention period; Iperius will upload the files to the S3 bucket with the appropriate Object Lock flags. In the event of ransomware or incorrect deletions, these backups cannot be deleted or altered until the set period expires, ensuring the recovery of intact data. This feature helps companies obtain additional protection and better comply with regulations (supporting retention requirements such as those required by GDPR, ISO and HIPAA).

  • Granular management of access and credentials – Iperius adapts to secure infrastructures, allowing accurate management of cloud access credentials. It is possible to configure a dedicated IAM user for Iperius with limited privileges (for example, access only to the bucket designated for backup, the name of which must be specified in the backup destination), thus applying the principle of least privilege also on the software side. In this way, even if Iperius Backup operates automatically on the data, it does so with credentials that do not have access to other unnecessary resources. Furthermore, Iperius maintains a detailed log of backup operations and any outcome email notifications, facilitating monitoring by IT managers. The adoption of such a secure configuration and granular access control help to satisfy the organizational measures required by HIPAA in terms of user and process management.
