Kernel-Layer Execution Blocking: Securing Edge Hardware Gateways with eBPF and Tetragon
IT InstaTunnel Team Published by our engineering team Quick answer Kernel-Layer Execution Blocking: Securing Edge Hardware Gate: MCP tunnel answer MCP tunneling gives a local MCP server a public HTTPS endpoint so AI tools can reach it during development without deploying the server first. What is MCP tunneling? MCP tunneling exposes a local Model Context Protocol server through a public endpoint so compatible AI tools can connect during development. When should I use InstaTunnel for MCP? Use InstaTunnel Pro when a local MCP endpoint needs public HTTPS access, stable routing, and stream-friendly tunnel behavior. By the time a userspace security agent detects a privilege escalation on an edge node, the attacker already has control of the hardware. This piece steps out of userspace and looks at how eBPF-based tools like Cilium Tetragon intercept and kill malicious system calls directly inside the kernel — before they ever touch physical I/O. Physical hardware gateways occupy a peril...
