Server-Side Encryption
Server-Side Encryption (SSE) is a security method where data is encrypted at rest on the server or storage system, typically using keys managed by the service provider. It protects sensitive information stored in databases, cloud storage, or file systems from unauthorized access if physical or logical security is breached. SSE is commonly implemented in cloud services like AWS S3, Azure Blob Storage, or Google Cloud Storage to automatically encrypt data as it's written.
Developers should use SSE when storing sensitive data in cloud environments or on-premises servers to meet compliance requirements (e.g., GDPR, HIPAA) and enhance data security without client-side modifications. It's essential for applications handling financial records, personal identifiable information (PII), or healthcare data, as it provides a transparent encryption layer that requires minimal code changes compared to client-side encryption.
