Mapped every skill to NIST CSF 2.0 subcategory IDs (GV/ID/PR/DE/RS/RC functions) based on subdomain and content analysis. Restores 11 skills corrupted during prior rebase, re-enriching with ATLAS, D3FEND, NIST AI RMF, and CSF 2.0 fields. All 754 skills now carry structured mappings for all 5 security frameworks: - MITRE ATT&CK (in tags) - MITRE ATLAS v5.5 (atlas_techniques) - MITRE D3FEND v1.3 (d3fend_techniques) - NIST AI RMF 1.0 (nist_ai_rmf) - NIST CSF 2.0 (nist_csf)

# Analyzing Kubernetes Audit Logs
|
|
|
|
|
|
## When to Use
|
|
|
|
- When investigating security incidents that require analyzing kubernetes audit logs
|
|
- When building detection rules or threat hunting queries for this domain
|
|
- When SOC analysts need structured procedures for this analysis type
|
|
- When validating security monitoring coverage for related attack techniques
|
|
|
|
## Prerequisites
|
|
|
|
- Familiarity with container security concepts and tools
|
|
- Access to a test or lab environment for safe execution
|
|
- Python 3.8+ with required dependencies installed
|
|
- Appropriate authorization for any testing activities
|
|
|
|
## Instructions
|
|
|
|
Parse Kubernetes audit log files (JSON lines format) to detect security-relevant
|
|
events including unauthorized access, privilege escalation, and data exfiltration.
|
|
|
|
```python
|
|
import json
|
|
|
|
with open("/var/log/kubernetes/audit.log") as f:
|
|
for line in f:
|
|
event = json.loads(line)
|
|
verb = event.get("verb")
|
|
resource = event.get("objectRef", {}).get("resource")
|
|
user = event.get("user", {}).get("username")
|
|
if verb == "create" and resource == "pods/exec":
|
|
print(f"Pod exec by {user}")
|
|
```
|
|
|
|
Key events to detect:
|
|
1. pods/exec and pods/attach (shell into containers)
|
|
2. secrets access (get/list/watch)
|
|
3. clusterrolebindings creation (RBAC escalation)
|
|
4. Privileged pod creation
|
|
5. Anonymous or system:unauthenticated access
|
|
|
|
## Examples
|
|
|
|
```python
|
|
# Detect secret enumeration
|
|
if verb in ("get", "list") and resource == "secrets":
|
|
print(f"Secret access: {user} -> {event['objectRef'].get('name')}")
|
|
```
