# API Reference: Building Cloud SIEM with Sentinel
|
|
|
|
## azure-monitor-query (KQL Queries)
|
|
|
|
```python
|
|
from azure.identity import DefaultAzureCredential
|
|
from azure.monitor.query import LogsQueryClient
|
|
from datetime import timedelta
|
|
|
|
credential = DefaultAzureCredential()
|
|
client = LogsQueryClient(credential)
|
|
|
|
response = client.query_workspace(
|
|
workspace_id="WORKSPACE_ID",
|
|
query="SigninLogs | where ResultType == 0 | take 10",
|
|
timespan=timedelta(hours=24),
|
|
)
|
|
for table in response.tables:
|
|
for row in table.rows:
|
|
print(row)
|
|
```
|
|
|
|
## azure-mgmt-securityinsight
|
|
|
|
```python
|
|
from azure.mgmt.securityinsight import SecurityInsights
|
|
|
|
client = SecurityInsights(credential, subscription_id)
|
|
|
|
# List analytics rules
|
|
for rule in client.alert_rules.list(rg, workspace):
|
|
print(rule.display_name, rule.severity)
|
|
|
|
# List incidents
|
|
for incident in client.incidents.list(rg, workspace):
|
|
print(incident.title, incident.severity)
|
|
```
|
|
|
|
## Key KQL Patterns for Sentinel
|
|
|
|
```kql
|
|
// Impossible travel
|
|
SigninLogs | where ResultType == 0
|
|
| extend Distance = geo_distance_2points(...)
|
|
|
|
// AWS credential abuse
|
|
AWSCloudTrail | where EventName == "AssumeRole"
|
|
| summarize dcount(SourceIpAddress) by UserIdentityArn
|
|
|
|
// Threat intelligence matching
|
|
let TI = ThreatIntelligenceIndicator | distinct NetworkIP;
|
|
CommonSecurityLog | where DestinationIP in (TI)
|
|
```
|
|
|
|
## Sentinel Data Connectors
|
|
|
|
| Connector | Data Table |
|
|
|-----------|-----------|
|
|
| Azure AD | `SigninLogs`, `AuditLogs` |
|
|
| AWS CloudTrail | `AWSCloudTrail` |
|
|
| Microsoft 365 | `OfficeActivity` |
|
|
| Defender for Cloud | `SecurityAlert` |
|
|
| Syslog | `Syslog` |
|
|
| CEF | `CommonSecurityLog` |
|
|
