Secure DevOps Pipelines for Continuous Compliance in Oracle– Cassandra Hybrid Systems

Hybrid data platforms that pair Oracle RDBMS with Apache Cassandra deliver both ACID guarantees and internet-scale availability, yet they complicate security and regulatory compliance. We present a DevSecOps pipeline that enforces continuous compliance across application code, database schema/DDL, infrastructure, and runtime posture. Our framework integrates policy-as-code, secure SDLC gates (SAST/DAST/IAST), IaC scanning, database migration controls for Oracle and Cassandra, secrets governance, drift detection, and runtime conformance checks. In a reference deployment, we reduced mean time to remediation (MTTR) of policy violations by 61%, prevented non-compliant schema changes pre-production, and achieved near-real-time evidence collection for audits. We discuss threat models, controls mapping (ISO/IEC 27001:2022, SOC 2, NIST SP 800-53 Rev.5, PCI DSS 4.0, GDPR, HIPAA, CIS Benchmarks), and trade-offs between speed and assurance.
