# Suricata High-Performance Network IDS/IPS

Configures Suricata IDS/IPS engine: multi-threaded packet capture (AF_PACKET, DPDK), Emerging Threats rule updates via suricata-update, eve.json alert output, and inline IPS drop actions.

## When to Invoke
Invoke this skill whenever you need to:
- configure suricata ids
- update suricata rules
- parse eve.json suricata

## Execution SOP & Rules
1. Configure suricata.yaml specifying interface name and af-packet capture settings.
2. Update threat detection signatures using suricata-update.
3. Enable eve-log JSON output format for seamless SIEM integration.
4. Operate in IPS mode (NFQ or inline AF_PACKET) to actively drop malicious traffic.

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
