analyzing-kubernetes-audit-logs
Parses Kubernetes API server audit logs (JSON lines) to detect exec-into-pod, secret access, RBAC modifications, privileged pod creation, and anonymous API access. Builds threat detection rules from audit event patterns. Use when investigating Kubernetes cluster compromise or building k8s-specific SIEM detection rules.

Analyzing Kubernetes Audit Logs
Instructions
Parse Kubernetes audit log files (JSON lines format) to detect security-relevant events including unauthorized access, privilege escalation, and data exfiltration.
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:
- pods/exec and pods/attach (shell into containers)
- secrets access (get/list/watch)
- clusterrolebindings creation (RBAC escalation)
- Privileged pod creation
- Anonymous or system:unauthenticated access
Examples
# Detect secret enumeration
if verb in ("get", "list") and resource == "secrets":
print(f"Secret access: {user} -> {event['objectRef'].get('name')}")

mapping-mitre-attack-techniques
Maps observed adversary behaviors, security alerts, and detection rules to MITRE ATT&CK techniques and sub-techniques to quantify detection coverage and guide control prioritization. Use when building an ATT&CK-based coverage heatmap, tagging SIEM alerts with technique IDs, aligning security controls to adversary playbooks, or reporting threat exposure to executives. Activates for requests involving ATT&CK Navigator, Sigma rules, MITRE D3FEND, or coverage gap analysis.
