Suricata IDS Deployment on ARM Architecture
Traditional Intrusion Detection Systems (IDS) are heavy and resource-intensive. This project demonstrates deploying Suricata on a Raspberry Pi 5 to create a formidable, edge-computing security node.
Architecture & Setup
The system is configured to monitor all traffic traversing the local gateway. We compiled Suricata from source to optimize for the ARM64 architecture, disabling unnecessary modules to preserve RAM.
Custom Rulesets
We didn't just use Emerging Threats (ET) open rules. I wrote custom PCRE (Perl Compatible Regular Expressions) to detect anomalous IoT telemetry specific to my local network, catching unencrypted MQTT packets instantly.
Verified Outcome
The node monitored live gateway traffic on the home lab and flagged the simulated attacks its rules were tuned for.
