Data Encryption, Masking, and PII Protection in AWS Data Lakes

In modern data architectures, securing sensitive information and maintaining regulatory compliance is a critical priority. This course provides a clear, step-by-step pathway to understanding how to protect Personally Identifiable Information (PII) and implement robust encryption strategies within the AWS ecosystem. You will transition from learning foundational security concepts to managing secure data flows across complex cloud environments. Through clear written explanations and structured architectural walkthroughs, you will learn how to design end-to-end data security policies. The course begins with core definitions of encryption and compliance standards, then guides you through configuring customer-managed keys, automating data classification, and masking sensitive fields to prevent unauthorized access. What you'll learn: - Understand the fundamentals of PII classification, data masking, and compliance requirements. - Configure AWS KMS with customer-managed keys for secure cross-account data sharing. - Implement server-side encryption strategies across S3 storage and Redshift data warehouses. - Automate the discovery and classification of sensitive data using Amazon Macie. - Enforce granular, column-level access controls and data masking policies using Lake Formation. - Apply modern zero-trust security principles to cloud-based data lake architectures. This text-based course is structured to build your confidence from the ground up, starting with essential security terminology before moving into practical configuration steps for S3, Glue, and Redshift. It is designed specifically for beginners, cloud practitioners, and data professionals who want to secure their cloud infrastructure without needing prior security engineering experience.
