Series 1, Episode 4.3: Practical Steps to Establish a Zero Trust Framework for Hybrid Cloud Environments

Hybrid cloud environments are complex yet indispensable for any journey of digital transformation. But this complexity often opens doors to vulnerabilities.🌐🔒

For a strong zero trust framework in hybrid clouds, an organization needs to undertake a series of strategic steps specific to such dynamic landscapes –

🛠️1. Ecosystem-wide assessment
Begin by visualizing all things: cloud assets, users, data flows, and access paths. This is the foundation of knowing where risks are, and where Zero Trust policy needs to be applied.
·      Applications requiring the most stringent protection
·      Pathways between on-prem and cloud assets that could be vulnerable
·      Inconsistent configurations between multi-cloud providers

🛡️2. Implement Micro-Segmentation
Divide the infrastructure into smaller segments, isolating areas where only necessary access is permitted.
·      Restrict database access to only those application servers that need it.
·      Segment cloud workloads by risk level to avoid lateral movement
By limiting access, breaches can be limited in their spread

👁️3. Strengthen Identity Verification
Replace static, one-time authentications with dynamic, context-aware verification.
·      Use device posture, location, and behavioral patterns for risk assessment
·      Enforce step-up authentication for sensitive operations
For example, require biometric verification when accessing admin tools from an unknown device.

📊4. Ensure End-to-End Encryption
Encrypt data at all stages—in use, in transit, and at rest. This provides another layer of protection that intercepted data is still unreadable.
·      TLS between applications in transit
·      Hybrid cloud storage through disk encryption

🧠 5. AI-powered security
AI and automation must be applied to make security scalable and quick in response. Use tools that
·      Detect anomalous patterns, such as spikes in data or login attempts from a geographically dispersed location
·      Automate threat containment for example, isolating affected workloads in real time
AI proactively monitoring to prevent attacks before causing harm to critical systems

WHAT’S IN IT FOR YOU?
·      Compliance: No hefty fines for failing to have protected data
·      Attack Surface: Reduce entry points and layers of security
·      Operational Efficiency: Secure hybrid cloud without compromising performance.
