# Infrastructure Security Fixes - Critical Issues Identified
|
||||
|
||||
## 🚨 CRITICAL SECURITY VULNERABILITIES
|
||||
|
||||
### **1. Environment Configuration Attack Surface - CRITICAL 🔴**
|
||||
|
||||
**Issue**: `.env.example` contains 300+ configuration variables with template secrets
|
||||
**Risk**: Massive attack surface, secret structure revelation, misconfiguration potential
|
||||
|
||||
**Current Problems**:
|
||||
```bash
|
||||
# Template secrets reveal structure
|
||||
ENCRYPTION_KEY=your-encryption-key-here
|
||||
HMAC_SECRET=your-hmac-secret-here
|
||||
BITCOIN_RPC_PASSWORD=your-bitcoin-rpc-password
|
||||
|
||||
# 300+ configuration variables in single file
|
||||
# No separation between dev/staging/prod
|
||||
# Multiple service credentials mixed together
|
||||
```
|
||||
|
||||
**Fix Required**:
|
||||
1. **Split environment configs** by service and environment
|
||||
2. **Remove template secrets** from examples
|
||||
3. **Use proper secret management** (AWS Secrets Manager, Kubernetes secrets)
|
||||
4. **Implement configuration validation**
|
||||
|
||||
### **2. Package Publishing Token Exposure - HIGH 🔴**
|
||||
|
||||
**Issue**: GitHub token used for package publishing without restrictions
|
||||
**Risk**: Token compromise could allow malicious package publishing
|
||||
|
||||
**Current Problem**:
|
||||
```yaml
|
||||
TWINE_PASSWORD: ${{ secrets.GITHUB_TOKEN }}
|
||||
NODE_AUTH_TOKEN: ${{ secrets.GITHUB_TOKEN }}
|
||||
# No manual approval required
|
||||
# Publishes on any tag push
|
||||
```
|
||||
|
||||
**Fix Required**:
|
||||
1. **Use dedicated publishing tokens** with minimal scope
|
||||
2. **Add manual approval** for production publishing
|
||||
3. **Restrict to specific tag patterns** (e.g., `v*.*.*`)
|
||||
4. **Implement package signing verification**
|
||||
|
||||
### **3. Helm Values Secret References - MEDIUM 🟡**
|
||||
|
||||
**Issue**: Some services lack explicit secret references
|
||||
**Risk**: Credentials might be hardcoded in container images
|
||||
|
||||
**Current Problems**:
|
||||
```yaml
|
||||
# Good example
|
||||
DATABASE_URL: secretRef:db-credentials
|
||||
|
||||
# Missing secret references for:
|
||||
# - API keys
|
||||
# - External service credentials
|
||||
# - Monitoring configurations
|
||||
```
|
||||
|
||||
**Fix Required**:
|
||||
1. **Audit all environment variables**
|
||||
2. **Add secret references** for all sensitive data
|
||||
3. **Implement secret validation** at deployment
|

## 🟢 POSITIVE SECURITY IMPLEMENTATIONS
|
||||
|
||||
### **4. Terraform Secrets Management - EXCELLENT ✅**
|
||||
|
||||
**Assessment**: Properly implemented AWS Secrets Manager integration
|
||||
|
||||
```hcl
|
||||
data "aws_secretsmanager_secret" "db_credentials" {
|
||||
name = "aitbc/${var.environment}/db-credentials"
|
||||
}
|
||||
```
|

|
||||
- ✅ Environment-specific secret paths
|
||||
- ✅ Proper data source usage
|
||||
- ✅ Kubernetes secret creation
|
||||
|
||||
### **5. CI/CD Security Scanning - EXCELLENT ✅**
|
||||

||||
**Assessment**: Comprehensive security scanning pipeline
|
||||
|
||||
**Features**:
|
||||
- ✅ Bandit security scans (Python)
|
||||
- ✅ CodeQL analysis (Python, JavaScript)
|
||||
- ✅ Dependency vulnerability scanning
|
||||
- ✅ Container security scanning (Trivy)
|
||||
- ✅ OSSF Scorecard
|
||||
- ✅ Daily scheduled scans
|
||||
- ✅ PR security comments
|
||||
|
||||
### **6. Kubernetes Security - EXCELLENT ✅**
|
||||
|
||||
**Assessment**: Production-grade Kubernetes security
|
||||
|
||||
**Features**:
|
||||
- ✅ Network policies enabled
|
||||
- ✅ Security contexts (non-root, read-only FS)
|
||||
- ✅ Pod anti-affinity across zones
|
||||
- ✅ Pod disruption budgets
|
||||
- ✅ TLS termination with Let's Encrypt
|
||||
- ✅ External managed services (RDS, ElastiCache)

## 🔧 IMMEDIATE FIX IMPLEMENTATION
|
||||
|
||||
### **Fix 1: Environment Configuration Restructuring**
|
||||
|
||||
Create separate environment configurations:
|
||||
|
||||
```bash
|
||||
# Structure to implement:
|
||||
config/
|
||||
├── environments/
|
||||
│ ├── development/
|
||||
│ │ ├── coordinator.env
|
||||
│ │ ├── wallet-daemon.env
|
||||
│ │ └── explorer.env
|
||||
│ ├── staging/
|
||||
│ │ ├── coordinator.env
|
||||
│ │ └── wallet-daemon.env
|
||||
│ └── production/
|
||||
│ ├── coordinator.env.template
|
||||
│ └── wallet-daemon.env.template
|
||||
└── security/
|
||||
├── secret-validation.yaml
|
||||
└── environment-audit.py
|
||||
```
|
||||
|
||||
### **Fix 2: Package Publishing Security**
|
||||
|
||||
Update publishing workflow:
|
||||
```yaml
|
||||
# Add manual approval
|
||||
on:
|
||||
push:
|
||||
tags:
|
||||
- 'v[0-9]+.[0-9]+.[0-9]+' # Strict version pattern
|
||||
|
||||
# Use dedicated tokens
|
||||
env:
|
||||
TWINE_USERNAME: ${{ secrets.PYPI_USERNAME }}
|
||||
TWINE_PASSWORD: ${{ secrets.PYPI_TOKEN }}
|
||||
NODE_AUTH_TOKEN: ${{ secrets.NPM_TOKEN }}
|
||||
|
||||
# Add approval step
|
||||
- name: Request manual approval
|
||||
if: github.ref == 'refs/heads/main'
|
||||
uses: trstringer/manual-approval@v1
|
||||
with:
|
||||
secret: ${{ github.TOKEN }}
|
||||
approvers: security-team, release-managers
|
||||
```
|
||||
|
||||
### **Fix 3: Helm Values Secret Audit**
|
||||
|
||||
Script to audit missing secret references:
|
||||
```python
|
||||
#!/usr/bin/env python3
|
||||
"""
|
||||
Audit Helm values for missing secret references
|
||||
"""
|
||||
|
||||
import yaml
|
||||
import re
|
||||
|
||||
def audit_helm_values(file_path):
|
||||
with open(file_path) as f:
|
||||
values = yaml.safe_load(f)
|
||||
|
||||
issues = []
|
||||
|
||||
def check_secrets(obj, path=""):
|
||||
if isinstance(obj, dict):
|
||||
for key, value in obj.items():
|
||||
current_path = f"{path}.{key}" if path else key
|
||||
if isinstance(value, str):
|
||||
# Check for potential secrets
|
||||
if any(keyword in value.lower() for keyword in
|
||||
['password', 'key', 'secret', 'token', 'credential']):
|
||||
if 'secretRef:' not in value:
|
||||
issues.append(f"Potential secret at {current_path}: {value}")
|
||||
check_secrets(value, current_path)
|
||||
elif isinstance(obj, list):
|
||||
for i, item in enumerate(obj):
|
||||
check_secrets(item, f"{path}[{i}]")
|
||||
|
||||
check_secrets(values)
|
||||
return issues
|
||||
|
||||
if __name__ == "__main__":
|
||||
issues = audit_helm_values("infra/helm/values/prod/values.yaml")
|
||||
for issue in issues:
|
||||
print(f"⚠️ {issue}")
|
||||
```
|
||||
