# Configuring Suricata For Network Monitoring

## Overview

Cybersecurity skill for configuring suricata for network monitoring. Follows industry best practices and security standards.

## When to Use
**Trigger phrases:**
- "configuring suricata for network monitoring"
- "Deploys and configures Suricata IDS/IPS with Emerging Threats rulesets, EVE JSON"


- Deploying a high-performance IDS/IPS capable of multi-threaded packet processing for 10+ Gbps network links
- Monitoring network traffic with protocol-aware inspection for HTTP, TLS, DNS, SMB, and other protocols
- Generating structured EVE JSON logs for direct SIEM ingestion without custom parsers
- Running in inline (IPS) mode to actively block malicious traffic at network choke points
- Combining signature-based detection with protocol anomaly detection and file extraction

**Do not use** as a standalone security solution without complementary controls, for encrypted traffic inspection without TLS decryption capabilities, or on systems with insufficient CPU/memory for the expected traffic volume.


## When NOT to Use

- When you lack proper authorization for testing
- For production systems without change management
- When the task requires legal or compliance expertise beyond technical scope


## Prerequisites

- Suricata 7.0+ installed from PPA or source (`suricata --build-info`)
- Network interface on a span port, tap, or inline bridge for traffic capture
- AF_PACKET or DPDK support for high-performance packet capture
- Emerging Threats Open or Pro ruleset subscription (or Snort Talos rules via oinkcode)
- suricata-update tool for automated rule management
- Elasticsearch/Kibana or Splunk for log analysis and visualization

## Workflow

```python
# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs(text: str) -> dict:
    return {k: re.findall(v, text) for k, v in IOC_PATTERNS.items()}
```

1. **Define Objectives** — Clarify the goals and scope for suricata.
2. **Gather Resources** — Collect tools, data, and access needed for suricata.
3. **Execute Process** — Carry out suricata operations methodically.
4. **Verify Quality** — Check results against acceptance criteria.
5. **Document Outcomes** — Record findings, decisions, and next steps.

## Tools

- **network monitoring** — Primary tool for this skill
- **Analysis Platform** — Data processing and visualization
- **Collaboration Tools** — Team coordination and knowledge sharing


## Process

1. **Design** — Define interface, identify patterns, plan implementation
1. **Implement** — Write code following existing conventions, add tests
1. **Verify** — Run tests, check integration, validate behavior

## Verification

- [ ] All suricata procedures executed completely and documented
- [ ] Findings validated against multiple data sources
- [ ] False positives identified and filtered
- [ ] Results documented with evidence and timestamps
- [ ] Recommendations provided with risk-based prioritization

## Anti-Rationalization Table

| Rationalization | Reality |
|---|---|
| "We are too small to be targeted" | Automated attacks target everyone. Size does not matter. |
| "Security slows us down" | A breach slows you down 100x more. Build security in from the start. |
| "We will fix it after launch" | Vulnerabilities in production are exploited within hours. Fix before deploy. |
