Tech Radar: eBPF Zero-Trust Security for AI Agents with Tetragon 1.4 Answer-First: Granting tool-execution permissions to AI Agents dramatically expands the attack surface for Remote Code Execution (RCE) via Prompt Injection. Cilium Tetragon 1.4 leverages eBPF probes inside the Linux kernel to intercept unauthorized syscalls, executing SIGKILL termination in under 15 microseconds before malicious payloads can exfiltrate sensitive data. 1. The Emerging Threat Vector: Autonomous Agent RCE In modern agentic architectures, autonomous agents are granted tool execution permissions across the host environment: ...

Tech Radar: NIST AI 600-1 & OWASP ASI01–ASI10 — Hardening Enterprise Agent Gateways in Kubernetes Answer-first: Deploying autonomous AI agent swarms into enterprise Kubernetes clusters demands a paradigm shift from Least Privilege to Least Agency. By unifying NIST AI 600-1 (the 12 GenAI Risk Categories across GOVERN/MAP/MEASURE/MANAGE) with the OWASP ASI Top 10 (2026 Agentic Security Standards), production architectures enforce a 4-tier defense: L7 Kubernetes Gateway API with CEL expressions for tool parameter sanitization, SPIFFE/SPIRE for ephemeral Non-Human Identity (NHI) mTLS attestation, and Cilium Tetragon eBPF for real-time Linux kernel syscall termination (SIGKILL < 15µs). ...

Production-grade Kubernetes Operator and eBPF kernel observability guide using Kubebuilder v4 and cilium/ebpf. Features C eBPF kernel probes (sys_execve, tcp_connect), zero-copy BPF ringbuffers (BPF_MAP_TYPE_RINGBUF), CRD controllers with status subresources, and deployment without privileged mode.

Building Custom Kubernetes Operators in Go with kubebuilder & Deep eBPF Kernel Observability using cilium/ebpf Answer-first: Building custom Kubernetes operators in Go with eBPF and Cilium enables kernel-level network packet filtering, zero-overhead observability tracing, and dynamic security policy enforcement. Implementing this architecture enforces sub-50ms P99 latency guarantees, zero-allocation memory pooling with Go 1.24 unique.Handle, and fault-tolerant Dapr 1.15 component orchestration for resilient production scaling. This design guarantees sub-50ms P99 latency bounds and zero-allocation memory pooling. ...
