=======Secrets Management
Cross-Platform Security Solution with HashiCorp Vault
From Scattered Secrets to Centralized Security
🎯 The Challenge: Enterprise Secrets Management
Required to implement a centralized secrets management solution across AWS, Azure, and Google Cloud environments with automated rotation, audit logging, and compliance controls while eliminating hardcoded credentials and reducing security risks.
🚨 The Security Challenge
- Scattered Secrets: Credentials stored in code, config files, and environment variables
- Manual Rotation: No automated password rotation leading to stale credentials
- Compliance Gaps: No audit trails or access controls for sensitive data
- Multi-Cloud Complexity: Different secret stores across cloud providers
- Security Incidents: Risk of credential exposure and unauthorized access
🏗️ Centralized Secrets Management Architecture
Designed and implemented a comprehensive secrets management platform using HashiCorp Vault as the central engine with cloud-native integrations, automated rotation, and zero-trust security principles.
🔐 HashiCorp Vault
Central secrets engine with encryption and access control
☁️ AWS Secrets Manager
Native AWS integration and RDS credential rotation
🔑 Azure Key Vault
Azure-native secrets and certificate management
🛡️ Google Secret Manager
GCP-native secrets with IAM integration
⚙️ Terraform
Infrastructure as Code for consistent deployments
🔄 External Secrets
Kubernetes operator for automatic secret injection
📊 Audit Logging
Comprehensive access logging and compliance reporting
🤖 Cert-Manager
Automated certificate lifecycle management
🏗️ Secrets Management Components
- Central Vault: HashiCorp Vault cluster with high availability and disaster recovery
- Cloud Integration: Native secret stores for each cloud provider with centralized policies
- Kubernetes Integration: External Secrets Operator for seamless secret injection
- Certificate Management: Automated PKI with cert-manager and Let's Encrypt
