Syswarden とは？

SysWarden is an ultra-lightweight Host-based Security Orchestrator for Linux. Acting as a powerful alternative to eBPF/XDP, it drops malicious packets directly at the hardware level (Layer 2/3) to prevent CPU overhead By fusing Data-Shield IPv4 blocklists, CINS Army, Blocklist.de, GeoIP, ASN tracking, a dynamic L7 WAF (Fail2ban), and a strict Zero-Trust Catch-All policy, it neutralizes 97% of internet noise with a near-zero memory footprint.
