Zero trust network access (ZTNA), a security model where no user is inherently trusted, has emerged as a crucial strategy for enterprise access control and security. ZTNA is driven by the growing use of SaaS / cloud applications, the rise in work-from-anywhere and increasingly evasive cyberthreats. Central to zero-trust and ZTNA is the concept of continuous adaptive trust, which uses real-time identity and context to authenticate and manage user sessions. Continuous adaptive trust requires fine-grained data points from across the network, which in turn hinge on advanced traffic filtering tools capable of processing infinite user sessions, while handling application complexities and stricter encryption, obfuscation and anonymization.
This whitepaper discusses current visibility gaps and challenges faced by ZTNA vendors. It introduces next-gen deep packet inspection (DPI) and illustrates how ipoque’s cutting-edge DPI engines, R&S®PACE 2 and R&S®vPACE, combine advanced traffic detection techniques such as behavioral, statistical and heuristic analysis, and encrypted traffic intelligence (ETI) alongside metadata extraction to reliably and accurately classify traffic by application, protocol and service type. It illustrates how DPI insights feed into ZTNA’s dynamic access rules and security policies, taking into account different user privileges, resource risk profiles and data sensitivity.
Why read this whitepaper
Discover how next-gen DPI reinforces a comprehensive zero-trust execution by enabling least privilege access (LPA) and microsegmentation, and how it supports various mechanisms such as multi-factor authentication and monitoring of BYOD / unmanaged devices. Learn how it strengthens ZTNA security by detecting anomalous, suspicious and malicious traffic patterns in real-time. Find out how granular traffic logs from DPI power next-gen ZTNA solutions in terms of performance and AI-based automation, and how it supports forward features such as API identification and DEM. This paper also illustrates several ZTNA use cases, namely Secure Service Edge (SSE), IIoT-based smart manufacturing and private 5G campus networks, and how DPI greatly enhances ZTNA’s effectiveness and efficiency.
