Abstract

The article addresses the problem of building a scalable Network Security Architecture for mission-critical workloads in connected-car and automotive enterprise environments. Relevance follows from the growth of externally exposed application surfaces, distributed identities, and high-availability requirements under continuous adversarial pressure. Novelty lies in an architecture-level synthesis that connects Web Application Firewall (WAF), Intrusion Prevention System (IPS), Network Access Control (NAC), Zero-Trust policy enforcement, Privileged Access Management (PAM), Data Access Control (DAC), SIEM-driven visibility, and DDoS Mitigation into a single evidence-producing security fabric. The work aims to derive an implementable reference design that scales across multi-cloud workloads while remaining auditable and operationally sustainable. The approach relies on analytical comparison and structured source review, combining maturity-model guidance with recent research on WAF intelligence, cloud intrusion detection and prevention, DDoS defense systems, and security automation for detection/response symmetry. The closing part outlines measurable outcome categories for uptime, compliance, risk reduction, and cost efficiency. The article targets security architects, SRE teams, and cloud platform engineers.

Keywords: Network Security Architecture, Web Application Firewall, Intrusion Prevention System, Network Access Control.
