Running Suricata against PCAPs offline and validating results via eve.json.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Suricata Offline Mode + EVE JSON

This skill covers running Suricata against PCAPs offline and validating results via `eve.json`.

## Run Suricata on a PCAP
Typical offline invocation:

```bash
suricata -c /root/suricata.yaml -S /root/local.rules -k none -r /root/sample.pcap -l /tmp/suri
```

Flags:
- `-r <pcap>`: replay a PCAP offline
- `-S <rules>`: load only the specified rules file
- `-l <dir>`: log directory (will contain `eve.json`)
- `-k none`: ignore checksum issues

## Inspect alerts in EVE JSON
Count alerts:

```bash
jq -r 'select(.event_type=="alert") | .alert.signature_id' /tmp/suri/eve.json | wc -l
```

See alert ids and messages:

```bash
jq -r 'select(.event_type=="alert") | [.alert.signature_id,.alert.signature] | @tsv' /tmp/suri/eve.json
```

## Practical tips
- Always check Suricata exits cleanly (no rule parse errors).
- Use a fresh `-l` directory per run to avoid mixing logs.
- Ensure your rule triggers only on the intended traffic by testing positive and negative PCAPs.

## Tight feedback loop (recommended)
When iterating on `/root/local.rules`, use this loop:

```bash
# 1) Validate rule syntax
suricata -T -c /root/suricata.yaml -S /root/local.rules

How to install

The exact contents, by fingerprint
mdr add benchflow-ai/benchflow/suricata-offline-evejson@sha256:5ef330a5329e945c

The line at the top of this page pins the label git:20260610.e2a435f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
