NorthStar Security Architecture & Engineering

Ten projects. One coherent enterprise-security story.

The NorthStar portfolio moves from secure foundations to identity, detection, delivery controls and architecture. Each project links to its public evidence and documentation.

01 · NETWORK SECURITY

Azure Network Security Lab — VNet Segmentation & NSG Troubleshooting

Designed segmented Azure networking, implemented subnet-level NSG controls, analysed effective rules and documented repeatable Bicep and Azure CLI deployment planning.

02 · IDENTITY & ACCESS

Enterprise IAM & Zero Trust Architecture

Extended an implemented Entra identity lab into a hybrid AD/Entra architecture for a fictional 5,500-person enterprise, covering JML/IGA, federation, privileged access and workload identities. Includes ten design decisions, a threat model and sixteen acceptance scenarios; enterprise deployment tests remain pending.

03 · SECURITY OPERATIONS & AUTOMATION

SOC Automation Lab — Sentinel Detection, Approval-Gated SOAR & Incident Response

Tuned WAF detection from 30 days of telemetry, remediated 455 legacy incidents, automated approval workflows for Medium and High incidents, and deployed a least-privilege managed-identity Logic App response playbook with ten live configuration checks.

04 · CLOUD FOUNDATION

Secure Azure Landing Zone — Segmented Infrastructure & WAF

Built a Terraform-managed Azure landing zone with segmented networking, Application Gateway WAF, App Service, Key Vault, managed identities and Sentinel detection.

07 · HYBRID CLOUD ARCHITECTURE

Hybrid Enterprise Cloud Architecture — Connectivity, DNS & Migration

Designed on-premises-to-Azure connectivity, hub/spoke routing, hybrid DNS, AD/Entra dependencies, private access, and migration/recovery. Includes eight design decisions and fourteen acceptance tests; deployment validation remains pending.

08 · APPLICATION SECURITY

Application & API Security — ZAP, Gateway Controls & CI Retesting

Built an isolated Juice Shop/ZAP pipeline in GitHub Actions. Validated CSP/CORS gateway controls with baseline and retest scans covering 95 URLs each, Chromium compatibility checks, and a selected-control regression gate. Dependency and inline-style findings remain documented.

09 · AWS CLOUD GOVERNANCE

AWS Secure Landing Zone — Multi-Account Governance & Controls

Implemented a governed AWS multi-account foundation with Organizations, Control Tower, dedicated Security and Log Archive accounts, centralized AWS Config and organization-wide CloudTrail. Validated inherited workload configuration recording, S3 public-write prevention, log-file validation, Terraform validation and CI.

10 · KUBERNETES SECURITY

NorthStar Secure Kubernetes Platform — AKS, Workload Identity & Runtime Guardrails

Built a Terraform-managed AKS security foundation with Azure RBAC, restricted API access, workload identity, Key Vault CSI secrets, Cilium network policy and Azure Policy. Validated secret retrieval, privileged-container denial, DNS access and blocked external egress.

Recent Verified Implementations

Operational security engineering backed by live validation.

These implementations extend the NorthStar Security Operations project with repeatable validation, evidence-driven detection tuning and approval-gated response automation.

VALIDATION AUTOMATION · VERIFIED

Azure & Microsoft Sentinel Operational State Validation

Built a policy-driven PowerShell validator that performs ten live Azure and Sentinel configuration checks, detects drift, produces sanitized JSON evidence and runs through GitHub Actions using passwordless OIDC.

SENTINEL SOAR · VERIFIED

Sentinel Operating Model & Approval-Gated SOAR

Analyzed 30 days of WAF telemetry, replaced a noisy match-all detection with a high-confidence rule, remediated 455 legacy incidents and deployed approval-gated automation with a least-privilege managed-identity Logic App.

Engineering approach

Controls have to make operational and business sense.

The portfolio distinguishes lab-validated work from target-state architecture. That boundary is deliberate: credible evidence beats inflated claims.

Design for least privilege

Identity, access and network choices start by reducing unnecessary pathways and excessive permissions.

Instrument and investigate

Controls are paired with telemetry, detection logic, investigation evidence and repeatable incident records.

Make delivery repeatable

Infrastructure-as-code, policy enforcement and documentation reduce drift and make technical handoff stronger.

Professional focus

Enterprise infrastructure experience, built toward modern cloud security.

My background includes Citrix remote access, Active Directory, VPN, Windows infrastructure, virtual desktop platforms, IAM/RBAC, security operations and incident troubleshooting. NorthStar shows how that enterprise foundation transfers into Azure security work.
