Securing Cloud Data Across AWS, Azure, and GCP

Introduction

As enterprises rapidly migrate workloads to the cloud, securing sensitive data across platforms such as AWS, Microsoft Azure, and Google Cloud Platform (GCP) has become a critical priority. While cloud providers secure the underlying infrastructure, data protection remains the customer’s responsibility.

IBM Guardium Data Protection addresses this challenge by delivering centralized visibility, real-time threat detection, and automated compliance across cloud-hosted databases and storage services. It enables organizations to monitor, audit, and protect sensitive data wherever it resides.

☁️ Cloud Security Challenges

Modern cloud environments introduce unique data protection challenges:

1. Data Sprawl

Sensitive data is often distributed across multiple databases, regions, and services—making it difficult to track and secure.

2. Limited Visibility

Native cloud monitoring tools may lack deep inspection and user-level activity tracking for databases.

3. Compliance Complexity

Regulations such as GDPR, HIPAA, PCI DSS, and SOX impose strict requirements that vary across regions and industries.

4. Shared Responsibility Model

Cloud providers secure infrastructure, but customers must secure their data, access controls, and configurations.
