Traditional remote access protection approaches (VPN, firewalls) are insufficient against modern threats such as distributed denial-of-service (DDoS), man-in-the-middle (MITM) attacks and insider threats. This study identifies five key architectural approaches to securing remote access and analyzes them in terms of security, implementation cost, management complexity and scalability. An integrated three-layer architecture is proposed that combines access control mechanisms (Zero Trust/SDP), dynamic network reconfiguration (Moving Target Defense) and client-side application protection (anti-tampering, antidebug). The results indicate that coordinating these mechanisms via a unified control loop improves the resilience of remote access to corporate hosting services while enabling phased adoption.
