Cloud & Infrastructure Security

I specialize in designing, implementing, and hardening cloud-native infrastructure with a focus on security, scalability, and automation. My work spans multi-cloud environments (AWS & GCP), where I apply principles like defense-in-depth, least privilege, and separation of duties through infrastructure as code (IaC), automated guardrails, and policy-driven enforcement.

My strategy revolves around building platforms that are secure by design — embedding controls at every layer: identity, network, workload, data, and runtime. I ensure that misconfigurations are minimized, blast radius is controlled, and human access is tightly governed using PoLP and Zero Trust principles.

🔧 Tools & Technologies

Cloud: AWS (VPC, EKS, IAM, GuardDuty, KMS, Security Hub), GCP (GKE, IAM, Cloud Logging, SCC, Chronicle)
IaC: Terraform, CloudFormation, Sentinel Policies, OPA Gatekeeper
Security Controls: IAM Conditions, SCPs, Organizational Policies, RBAC, PodSecurityStandards
Monitoring & Observability: CloudTrail, CloudWatch, Prometheus, ELK Stack, Chronicle SIEM

📌 Real-World Implementation

In a recent enterprise-grade engagement, I led the secure infrastructure design for a microservices-based application on AWS EKS. The goal was to build a resilient Zero Trust architecture that passed compliance audits (SOC2, ISO 27001) and supported rapid CI/CD releases without compromising posture.

Network Segmentation: VPCs with dedicated private subnets, isolated NAT gateways, and granular route tables
IAM Enforcement: Scoped IAM policies using Terraform, IRSA for Kubernetes, and session-bound temporary credentials
Runtime Hardening: PodSecurityPolicies (PSP), OPA Gatekeeper admission controls, and namespace-level RBAC
Policy as Code: Terraform Sentinel for mandatory tagging, encryption, and logging checks across environments
Centralized Logging: Unified GKE/EKS logging via CloudWatch + Chronicle SIEM, mapped to MITRE ATT&CK
Separation of Duties: Workload access roles separated from infrastructure roles with strict IAM boundary policies

🧠 Strategic Approach

My approach to cloud security is proactive and codified. I believe security must be built into the CI/CD lifecycle—not retrofitted. This includes:

Shifting left through pre-deployment policy validation and unit testing of Terraform plans
Using OPA and Sentinel to enforce compliance gates before merge
Implementing runtime protection (Falco, auditd) post-deployment for defense-in-depth
Auto-remediating drift and misconfig using tools like AWS Config Rules and GCP Policy Controller

📈 Outcomes & Impact

✅ Reduced misconfiguration risk by 70% across environments via codified controls
✅ Cut incident response time by 45% using centralized logging + threat detection
✅ Delivered compliant infrastructure for ISO 27001, SOC2, GDPR with audit-ready controls
✅ Accelerated developer velocity by enabling secure, self-service infrastructure pipelines
