# Search Attack Logs - IPS Signatures

Search for intrusion prevention system (IPS) attack logs and security threats.

> **✅ All code examples tested:** Verified against FortiAnalyzer v7.4.8, v7.6.4, v8.0.0.

## Overview

This example shows how to search IPS/IDS attack logs for detected security threats - useful for:
- Monitoring intrusion attempts and attacks
- Security incident investigation
- Threat analysis and pattern recognition
- Compliance reporting on security events
- SOC operations and threat hunting

This operation uses the **two-step asynchronous pattern**. See the [LogView Search Overview](../pilot/logview-search.md) for complete workflow details.

## Endpoint Details

**Method:** `POST`
**URL:** `/jsonrpc`
**API Path (Step 1):** `/logview/adom/{adom}/logsearch`
**API Path (Step 2):** `/logview/adom/{adom}/logsearch/{tid}`

##Step 1: Submit Search Request

### Key Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `adom` | `string` | Yes | ADOM name (e.g., "root") |
| `logtype` | `string` | Yes | Must be `"attack"` for IPS logs |
| `filter` | `string` | No | Optional filter expression |
| `time-range` | `object` | Yes | Time range for search |

### Filter Examples

**By Severity:**
```
severity=critical
severity=high
```

**By Attack Name:**
```
attack contains "SQL.Injection"
attack contains "XSS"
```

**By Source IP:**
```
srcip==10.0.1.100
```

**By Action:**
```
action=dropped
action=detected
```

## Use Cases

### Monitor Critical Attacks

```python
logs = search_attack_logs(
    session_id=session,
    adom="root",
    time_range={"last-n-hours": 24},
    filter_expr="severity=critical"
)
```

### Investigate Specific Attack Type

```python
logs = search_attack_logs(
    session_id=session,
    adom="root",
    time_range={"last-n-hours": 48},
    filter_expr='attack contains "SQL.Injection"'
)
```
