Making Zero Trust Work

In this insightful presentation, Rahul Jadhav from AccuKnox delves into the practical challenges and solutions involved in implementing and maintaining Zero Trust security in modern cloud-native environments. Titled “Making Zero Trust Work”, the talk highlights how organizations can achieve a strong security posture using the AccuKnox Cloud-Native Application Protection Platform (CNAPP), which supports a multi-layered Zero Trust approach.

Zero Trust is a journey, not a destination. Reaching a Zero Trust state—where only known, specific behaviors are permitted and all else is denied—is only half the battle. Maintaining that state over time requires ongoing effort, particularly in dynamic environments like Kubernetes, where applications and infrastructure change rapidly. Rahul outlines the two critical elements necessary for effective Zero Trust: policy engines that enforce least-permissive access, and operational frameworks that detect and adapt to changes in real-time.

Drawing from NIST’s Zero Trust Architecture principles, the video explores key enforcement dimensions in a cloud-native context. These include:

• Network and API access
• System behavior (processes, file access, capabilities)
• Data access to sensitive information

AccuKnox has developed a powerful suite of tools to manage these dimensions effectively. KubeArmor, for instance, allows administrators to define fine-grained policies specifying which processes are allowed, what files can be accessed, and which network destinations are permitted. KTLs ensures secure communication by validating TLS configurations across Kubernetes services. AccuKnox’s KIM tool helps manage Kubernetes identities and entitlements, contributing to a robust identity-first security model.

Yet technology alone isn’t enough. Rahul emphasizes that the depth of policy enforcement must be balanced against operational resilience. Too strict a policy can result in fragility, where even minor application updates cause failures. AccuKnox addresses this challenge by identifying optimal policy depth—deep enough for security, but flexible enough to accommodate change.

A major focus is the policy lifecycle and user experience. AccuKnox enables organizations to deploy policies in “audit” or “dry run” mode before enforcing them fully. This allows for safe testing of changes, reducing the risk of application downtime. Granular control is provided, with the ability to apply audit or deny modes at the level of files, processes, or network behavior—across namespaces or individual workloads.

Another unique aspect of the AccuKnox solution is its tight integration with CI/CD pipelines. By detecting behavioral deviations early in the development process—such as new processes, endpoints, or network activity—developers and DevOps teams are alerted about potential Zero Trust violations before the code reaches production. This “shift-left” approach ensures that security is embedded early and evolves with the application.

Rahul also addresses a common pitfall: reliance on post-attack mitigation. Traditional solutions react after malicious code executes, which is too late in scenarios like ransomware attacks. In contrast, AccuKnox supports inline mitigation, which blocks unauthorized behavior at runtime before it can cause harm. Powered by security primitives like eBPF and Linux Security Modules (LSMs), the platform ensures enforcement without relying on vulnerable mechanisms like time-to-check/time-to-use.

The video concludes by emphasizing the importance of periodic Zero Trust efficacy evaluations. By enabling collaboration between red and blue teams and providing measurable insights into security control effectiveness, organizations can validate and enhance their Zero Trust posture over time.

Ultimately, “Making Zero Trust Work” is a practical guide for security teams navigating the complexities of Zero Trust in modern environments. AccuKnox’s CNAPP framework offers the tools and methodologies needed to secure cloud-native applications with confidence, adaptability, and precision.
