# API Reference: Analyzing Kubernetes Audit Logs
|
|
|
|
## Audit Log Format (JSON Lines)
|
|
|
|
```json
|
|
{
|
|
"kind": "Event",
|
|
"apiVersion": "audit.k8s.io/v1",
|
|
"level": "RequestResponse",
|
|
"verb": "create",
|
|
"user": {"username": "admin", "groups": ["system:masters"]},
|
|
"sourceIPs": ["10.0.0.5"],
|
|
"objectRef": {
|
|
"resource": "pods",
|
|
"subresource": "exec",
|
|
"namespace": "default",
|
|
"name": "web-pod"
|
|
},
|
|
"responseStatus": {"code": 200},
|
|
"requestReceivedTimestamp": "2025-03-15T14:00:00Z"
|
|
}
|
|
```
|
|
|
|
## Security-Critical Audit Events
|
|
|
|
| Event | objectRef | Severity |
|
|
|-------|-----------|----------|
|
|
| Pod exec | `resource: pods, subresource: exec` | HIGH |
|
|
| Secret access | `resource: secrets, verb: get/list` | HIGH |
|
|
| RBAC change | `resource: clusterrolebindings` | CRITICAL |
|
|
| Privileged pod | `requestObject.spec.containers[].securityContext.privileged` | CRITICAL |
|
|
| Anonymous access | `user.username: system:anonymous` | CRITICAL |
|
|
|
|
## Audit Policy Levels
|
|
|
|
| Level | Captures |
|
|
|-------|----------|
|
|
| None | No logging |
|
|
| Metadata | Timestamp, user, verb, resource |
|
|
| Request | Metadata + request body |
|
|
| RequestResponse | Request + response body |
|
|
|
|
## Python Parsing
|
|
|
|
```python
|
|
import json
|
|
with open("audit.log") as f:
|
|
for line in f:
|
|
event = json.loads(line)
|
|
print(event["verb"], event["objectRef"]["resource"])
|
|
```
