Zero-Trust Remote Access & Identity-Aware ArchitectureRené Bon Ćirić
Eliminate vulnerable, slow, and brittle perimeter VPN appliances (OpenVPN, Cisco AnyConnect, Pulse Secure), prevent ransomware lateral movement across internal networks, and establish continuous identity-aware access control.
We design and implement a modern, enterprise-grade Zero-Trust Architecture based on Identity-Aware Proxies (IAP), WireGuard peer-to-peer mesh networks, and mutual TLS (mTLS) micro-segmentation running on hardened CentOS Stream 10. Remote developers and internal staff securely access corporate applications through standard web browsers backed by enterprise Multi-Factor Authentication (MFA), without exposing a single open ingress VPN port to the public internet.
Architecture & Safety Invariants
Eliminate Lateral Movement: Zero Trust enforces least-privilege access per application, preventing a compromised laptop from scanning internal networks.
Frictionless Browser-Based Access: Internal tools are accessible directly via web browsers authenticated via corporate SSO/MFA without clunky client software.
Stealth Public Perimeters: Zero open public-facing VPN listener ports; all inbound connections are authenticated and authorized cryptographically before reaching services.
Micro-Segmented Workload Isolation: Service-to-service traffic between servers and containers is strictly encrypted and verified via mTLS or WireGuard overlays.
Tangible Engineering Deliverables
Identity-Aware Proxy (IAP) Gateway: Caddy/Traefik reverse proxy deployment integrated with corporate OAuth2/OIDC (Google, Okta, Microsoft Entra ID) and cryptographic session token verification.
Kernel-Native WireGuard Mesh Overlay: High-performance peer-to-peer WireGuard network connecting servers, cloud instances, and management bastions with automated key rotation.
Workload Mutual TLS (mTLS) Infrastructure: Dedicated private Certificate Authority issuing client certificates for API services, database listeners, and admin interfaces.
Hardened Perimeter Firewall & SELinux Confinement: Restrictive firewalld rules binding services to localhost and WireGuard interfaces under SELinux Enforcing posture.
Access Governance Runbook & Decommissioning Guide: Step-by-step procedures for employee onboarding/offboarding, access audits, and legacy VPN retirement.
