# CAST AI Security Basics
## Overview
Secure your CAST AI integration: API key management, RBAC least-privilege, Kvisor runtime security agent, and network policy configuration.
## Prerequisites
- CAST AI agent installed on cluster
- Cluster admin access for RBAC configuration
- Secrets manager (AWS Secrets Manager, Vault, etc.)
## Instructions
### Step 1: API Key Management
```bash
# Use separate keys per environment
# console.cast.ai > API > API Access Keys
# Development: Read-Only key (monitoring only)
# Staging: Full Access key with limited cluster scope
# Production: Full Access key, rotated every 90 days
# Store in secrets manager, never in code
aws secretsmanager create-secret \
--name "castai/prod/api-key" \
--secret-string "${CASTAI_API_KEY}"
# Rotate key procedure:
# 1. Generate new key in console
# 2. Update secrets manager
# 3. Restart CAST AI agent pods to pick up new key
# 4. Verify agent reconnects
# 5. Revoke old key in console
```
### Step 2: RBAC Least-Privilege Review
```bash
# Audit CAST AI ClusterRoles
kubectl get clusterroles -l app.kubernetes.io/managed-by=castai -o yaml
# The CAST AI agent needs these minimum permissions:
# - get/list/watch: pods, nodes, events, namespaces, replicasets
# - get: persistentvolumes, storageclasses
# The cluster controller additionally needs:
# - create/delete: nodes (for autoscaling)
# - patch: pods/eviction (for evictor)
# Check for overly broad permissions
kubectl auth can-i --list --as=system:serviceaccount:castai-agent:castai-agent
```
### Step 3: Enable Kvisor Security Agent
```bash
# Kvisor scans for CVEs, misconfigurations, and runtime threats
helm upgrade --install castai-kvisor castai-helm/castai-kvisor \
-n castai-agent \
--set castai.apiKey="${CASTAI_API_KEY}" \
--set castai.clusterID="${CASTAI_CLUSTER_ID}" \
--set controller.extraArgs.image-scan-enabled=true \
--set controller.extraArgs.kube-bench-enabled=true
# Verify Kvisor is running
kubectl get pods -n castai-agent -l app.kubernetes.io/name=castai-kvisor
```
### Step 4: Network Policies
```yaml
# Restrict CAST AI agent egress to only api.cast.ai
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
name: castai-agent-egress
namespace: castai-agent
spec:
podSelector:
matchLabels:
app.kubernetes.io/name: castai-agent
policyTypes:
- Egress
egress:
- to:
- ipBlock:
cidr: 0.0.0.0/0 # api.cast.ai resolves dynamically
ports:
- protocol: TCP
port: 443
- to: # Allow DNS
- namespaceSelector: {}
ports:
- protocol: UDP
port: 53
```
### Step 5: Security Checklist
- [ ] API keys stored in secrets manager, not Helm values files
- [ ] Separate keys per environment (dev/staging/prod)
- [ ] Read-only keys for monitoring-only clusters
- [ ] Key rotation scheduled every 90 days
- [ ] Kvisor enabled for image scanning and CIS benchmarks
- [ ] CAST AI namespace has network policies
- [ ] Agent RBAC reviewed and minimized
- [ ] Helm values files in `.gitignore`
- [ ] Audit logs enabled in CAST AI console
## Error Handling
| Issue | Detection | Mitigation |
|-------|-----------|------------|
| API key in git history | `git log -S "CASTAI"` | Rotate key immediately |
| Agent has cluster-admin | `kubectl auth can-i --list` | Apply scoped ClusterRole |
| Kvisor high resource use | `kubectl top pods -n castai-agent` | Adjust scan intervals |
| Network policy blocks agent | Agent goes offline | Allow egress to 443 |
