eBPF-Powered DDoS Mitigation: Dropping Malicious Packets at XDP Layer
Executive Summary: 3-Second Overview Dropping Packets at the Driver Level: Bypasses the heavy Linux kernel network stack entirely by utilizing XDP (eXpress Data Path) to neutralize volumetric DDoS attacks. Ultrafast eBPF Filtering: Executes sandboxed C programs directly inside the network interface card (NIC) driver for line-rate packet drop performance. Strategic Security ROI: Prevents CPU saturation and kernel panics during multi-terabit volumetric floods without requiring expensive dedicated scrubbing hardware. As volumetric distributed denial-of-service (DDoS) attacks routinely exceed multi-terabit scales, traditional iptables firewall rules and user-space packet filters fail catastrophically. Processing millions of malicious packets through the standard Linux network stack exhausts CPU softIRQ interrupts and causes complete service outages. Implementing eBPF-Powered DDoS Mitigation via the eXpress Data Path (XDP) allows infrastructure teams to inspect and drop mali...
