# Fortigate AI ML Inspection Agent
|
|
|
|
Local FortiGate log and policy inspection agent. It parses FortiGate syslog/JSONL logs, audits FortiOS policy exports, highlights UTM events, and can quarantine malicious source IPs through the FortiGate API when explicitly enabled.
|
|
|
|
Autoblocking is dry-run by default. The tool will not block RFC1918, loopback, multicast, link-local, reserved, or allowlisted addresses unless you change the code.
|
|
|
|
## Quick Start
|
|
|
|
```bash
|
|
python -m venv .venv
|
|
source .venv/bin/activate
|
|
pip install -e .
|
|
```
|
|
|
|
Analyze local logs:
|
|
|
|
```bash
|
|
fgai analyze-logs --logs logs/fg_syslog.jsonl
|
|
```
|
|
|
|
Test FortiGate API access:
|
|
|
|
```bash
|
|
export FORTIGATE_HOST=192.0.2.10
|
|
export FORTIGATE_API_TOKEN='...'
|
|
export FORTIGATE_VERIFY_TLS=false
|
|
fgai test-connection
|
|
fgai fetch-policies --output exports/policies.json
|
|
```
|
|
|
|
Audit a FortiGate policy export:
|
|
|
|
```bash
|
|
fgai audit-policies --config exports/fortigate.conf
|
|
```
|
|
|
|
Find block candidates without changing the firewall:
|
|
|
|
```bash
|
|
fgai suggest-blocks --logs logs/fg_syslog.jsonl
|
|
```
|
|
|
|
Execute guarded quarantine actions:
|
|
|
|
```bash
|
|
export FORTIGATE_HOST=192.0.2.10
|
|
export FORTIGATE_API_TOKEN='...'
|
|
fgai suggest-blocks --logs logs/fg_syslog.jsonl --execute --expiry-minutes 60
|
|
```
|
|
|
|
Optional local LLM summary through Ollama:
|
|
|
|
```bash
|
|
ollama pull llama3.3
|
|
fgai analyze-logs --logs logs/fg_syslog.jsonl --llm
|
|
```
|
|
|
|
## FortiGate Inputs
|
|
|
|
For logs, configure FortiGate syslog to write into a local file such as `logs/fg_syslog.jsonl`. The parser supports common key/value syslog lines and JSONL.
|
|
|
|
For policies, export a FortiOS config backup and pass it to `audit-policies`.
|
|
|
|
Example FortiGate syslog target, run on the FortiGate CLI and replace the server IP with this machine:
|
|
|
|
```text
|
|
config log syslogd setting
|
|
set status enable
|
|
set server "192.0.2.50"
|
|
set port 514
|
|
set mode udp
|
|
set format default
|
|
end
|
|
```
|
|
|
|
## Environment
|
|
|
|
- `FORTIGATE_HOST`: firewall hostname or IP.
|
|
- `FORTIGATE_API_TOKEN`: REST API token.
|
|
- `FORTIGATE_VERIFY_TLS`: `true` or `false`, defaults to `true`.
|
|
- `FGAI_ALLOWLIST`: comma-separated IPs/CIDRs never to block.
|
|
- `OLLAMA_HOST`: defaults to `http://127.0.0.1:11434`.
|
|
- `OLLAMA_MODEL`: defaults to `llama3.3`.
|
|
|
|
## Safety Model
|
|
|
|
The agent separates detection from enforcement:
|
|
|
|
- UTM events are scored from FortiGate logs (`ips`, `virus`, `anomaly`, `ddos`, `webfilter`, `app-ctrl`, `waf`, `dns`).
|
|
- Source IPs must be globally routable and outside the allowlist.
|
|
- Blocking requires `--execute`.
|
|
- The FortiGate API call is limited to the quarantine/banned user monitor endpoint.
