# Elasticsearch Recon Ingestion Scripts (ERIS)
> A utility for ingesting various large scale reconnaissance data logs into Elasticsearch

## Prerequisites
- [python](https://www.python.org/)
    - [elasticsearch](https://pypi.org/project/elasticsearch/) *(`pip install elasticsearch`)*

###### Performance arguments

###### Ingestion arguments
| Argument    | Description              |
|-------------|--------------------------|
| `--certs`   | Index Certstream records |
| `--httpx`   | Index HTTPX records      |
| `--masscan` | Index Masscan records    |
| `--massdns` | Index massdns records    |
| `--zone`    | Index zone DNS records   |

This ingestion suite will use the built in node sniffer, so by connecting to a single node, you can load balance across the entire cluster.
It is good to know how much nodes you have in the cluster to determine how to fine tune the arguments for the best performance, based on your environment.

## GeoIP Pipeline
Create & add a geoip pipeline and use the following in your index mappings:

```json
"geoip": {
    "city_name": "City",
    "continent_name": "Continent",
    "country_iso_code": "CC",
    "country_name": "Country",
    "location": {
        "lat": 0.0000,
        "lon": 0.0000
    },
    "region_iso_code": "RR",
    "region_name": "Region"
}
```

## Changelog
- Added ingestion script for certificate transparency logs in real time using websockets.
- `--dry-run` removed as this nears production level
- Implemented [async elasticsearch](https://elasticsearch-py.readthedocs.io/en/latest/async.html) into the codebase & refactored some of the logic to accomadate.
- The `--watch` feature now uses a FIFO to do live ingestion.
- Isolated eris.py into it's own file and seperated the ingestion agents into their own modules.

## Roadmap
- Fix issue with `ingest_certs.py` and not needing to pass a file to it
- WHOIS database ingestion scripts
- Dynamically update the batch metrics when the sniffer adds or removes nodes
