# Analyzing Azure Activity Logs for Threats


## Ne Zaman Kullanılır

- investigating yaparken security incidents that require analyzing azure activity logs for threats
- building yaparken Tespit rules or threat hunting queries for this domain
- SOC yaparken: analysts need structured procedures for this analysis type
- validating yaparken security monitoring coverage for related attack techniques

## Ön Gereksinimler

- Familiarity with security operations concepts and tools
- Erişim: a test or lab environment for safe execution
- Python 3.8+ with required dependencies installed
- Appropriate authorization for any testing activities

## Instructions

Use azure-monitor-query to execute KQL queries against Azure Log Analytics workspaces,
Tespit etme suspicious admin operations and sign-in anomalies.

```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="AzureActivity | where OperationNameValue has 'MICROSOFT.AUTHORIZATION/ROLEASSIGNMENTS/WRITE' | take 10",
    timespan=timedelta(hours=24),
)
```

Key Tespit queries:
1. Role assignment changes (privilege escalation)
2. Resource group and subscription modifications
3. Key vault secret access from new IPs
4. Network security group rule changes
5. Conditional access policy modifications

## Örnekler

```python
query = '''
AuditLogs
| where OperationName == "Add member to role"
| where TargetResources[0].modifiedProperties[0].newValue has "Global Administrator"
'''
```
