} - Polymorphic Malware: Modern threats change their code or communication patterns frequently to evade static signatures.
- Encrypted Traffic: With over 90% of web traffic now encrypted (TLS 1.3), traditional deep packet inspection (DPI) requires resource-heavy decryption proxies that introduce latency and privacy concerns.
- Zero-Day Vulnerabilities: By definition, a signature cannot exist for a threat that has never been seen before.
- Resource Exhaustion: Running thousands of signatures against gigabits of traffic at the edge (e.g., on a Raspberry Pi or an industrial gateway) is computationally impossible for legacy engines. - Identity Context: Who is the user or what is the device type (e.g., a Siemens PLC vs. a MacBook)?
- Behavioral Baseline: What are the typical entropy, frequency, and payload characteristics of this flow?
- Threat Intelligence: Real-time feeds from the global HookProbe ecosystem.
- Structural Analysis: Using graph-based modeling to detect lateral movement patterns. - Data Pod: Localized storage of high-fidelity telemetry.
- Detection Pod (NAPSE): The AI-native IDS/IPS engine.
- Response Pod (AEGIS): The autonomous defense mechanism that executes policy synthesis.
- Intelligence Pod: Connects to global threat feeds and the open-source HookProbe community. - Hardware Selection: For small environments, a Raspberry Pi 4 or an Intel NUC is sufficient. For enterprise edge, use any x86-64 server with XDP-compatible NICs.
- Installation: Deploy the HookProbe agent, which includes the NAPSE engine and the Neural-Kernel.
- Learning Phase: Allow NAPSE to observe network traffic for 24-48 hours to build its behavioral baseline.
- Policy Synthesis: Enable AEGIS to allow the system to automatically generate and apply eBPF filters based on NAPSE's detections.
