# Blast Radius Analysis: Alberto Polak

## Executive Summary

This report analyzes the potential security impact (blast radius) of user **Alberto Polak** within the Azure infrastructure. The analysis was conducted using graph-based security tools to map all accessible resources and evaluate the potential damage if this user account were compromised.

### Key Findings

- **Total Exposed Resources**: 33 Azure Key Vaults
- **Permission Type**: Direct "has permissions to" relationships
- **Resource Type**: All targets are Microsoft Key Vault instances
- **Subscription**: ab48f397-fc82-4634-aa52-62dd91b3ebaa
- **Risk Level**: **HIGH** - Extensive access to sensitive cryptographic key storage

---

## Detailed Blast Radius

### Impact Overview

If Alberto Polak's account is compromised, an attacker would gain immediate access to **33 Azure Key Vaults** containing sensitive cryptographic keys, secrets, and certificates. This represents a significant security exposure across multiple resource groups and critical infrastructure components.

### Attack Path Analysis

All identified paths are **direct single-hop connections**:
- **Path Length**: 1 step (direct access)
- **Access Method**: "has permissions to" edge relationship
- **No Additional Hops Required**: Attacker gains immediate access upon account compromise

| **sentineldemos** | woodgrove-rg | Sentinel Demo Environment |
| **DCEDCRKeyVault** | woodgrove-rg | Data Collection Configuration |

**Risk Assessment**: Compromise of security monitoring vaults could allow attackers to disable detection mechanisms, hide malicious activity, and maintain persistent access.

### Certificate & TLS Infrastructure (High Priority)

| Asset Name | Resource Group | Risk Category |
|------------|---------------|---------------|
| **fw-cert-kv-eodl1fmPodQrU** | woodgrove-rg | Firewall Certificates |
| **fw-cert-kv-4FYAYX0P5xO3H** | woodgrove-rg | Firewall Certificates |
| **fw-cert-kv-7Ar5j8JJkPbB1** | woodgrove-rg | Firewall Certificates |
| **myTLSKeyVault** | woodgrove-rg | TLS Certificates |
| **wg-entra-tls-inspection** | woodgrove-rg | Entra TLS Inspection |

**Risk Assessment**: Access to certificate vaults enables man-in-the-middle attacks, service impersonation, and bypass of encrypted communications.

### AI & Machine Learning Infrastructure (Medium-High Priority)

| Asset Name | Resource Group | Risk Category |
|------------|---------------|---------------|
| **kv-aoaihub265060096545** | woodgrove-mdc-ai | Azure OpenAI Hub |
| **kv-wgaihub098811020122** | wg-ai-hub | AI Hub Keys |

**Risk Assessment**: AI infrastructure keys could expose proprietary models, training data, and API endpoints for AI services.

### Identity & Authentication Services (Critical Priority)

| Asset Name | Resource Group | Risk Category |
|------------|---------------|---------------|
| **wg-verifiedemployee** | woodgroveverifiedemployee | Employee Verification |
| **wgyubipreregkv** | woodgroveyubicopoc | YubiKey Pre-registration |
| **CoreId-kv-c2gq** | coreid-rg-0x2y | Core Identity System |
| **ModernWork-kv-xa1e** | modernwork-rg-0x2y | Modern Work Platform |

**Risk Assessment**: Identity vaults contain authentication secrets that could enable privilege escalation and unauthorized access to user accounts.

### Enterprise Applications & Services (Medium Priority)

| Asset Name | Resource Group | Risk Category |
|------------|---------------|---------------|
| **myaccountlinkedin** | appsvc_linux_centralus_basic | Application Service |
| **VmsParkcity** | woodgrove-alpine | VM Management |
| **parkcitySAP-KV** | woodgrove-alpine | SAP System Keys |
| **woodgrove-ksi-keyvault** | woodgrove-rg | KSI Integration |
| **MyKeyVault12** | woodgrove-rg | General Purpose Vault |
| **HubVNet-kv-l3sp** | hubvnet-rg-0x2y | Network Hub Keys |
| **mdtiworkbookm5xeucozid** | woodgrove-rg | MDTI Workbook |
| **payroll01** | woodgrove-sentinelgraph | Payroll System |
| **kv-ignite-adatum** | ignite-woodgroove | Event/Demo Vault |

**Risk Assessment**: These vaults support various business applications and could disrupt operations if compromised.

## Risk Metrics

### Blast Radius Severity: **CRITICAL**

- **Lateral Movement Potential**: Direct access to 33 Key Vaults with no intermediate steps
- **Data Exposure**: Secrets, certificates, and cryptographic keys across the entire infrastructure
- **Operational Impact**: Complete compromise could halt production systems, disable security controls, and enable persistent backdoor access
- **Compliance Impact**: Breach of key vaults could trigger regulatory reporting requirements (GDPR, SOC2, etc.)

### Vulnerability Indicators

- ❌ **No vulnerabilities detected in target nodes** (according to graph data)
- ⚠️ **Over-privileged Account**: Access to 33 Key Vaults indicates excessive permissions
- ⚠️ **Single Point of Failure**: One compromised account = full infrastructure exposure
- ⚠️ **No Segmentation**: Uniform access across dev, test, and production environments

---

## Recommendations

### Immediate Actions (Priority 1)

1. **Implement Least Privilege Access**
- Audit Alberto Polak's role requirements
- Revoke unnecessary Key Vault permissions
- Implement role-based access control (RBAC) with minimal required permissions

2. **Enable Enhanced Monitoring**
- Configure Azure Sentinel alerts for Key Vault access by this account
- Enable Azure AD Privileged Identity Management (PIM) for just-in-time access
- Set up anomaly detection for unusual access patterns

3. **Implement Multi-Factor Authentication (MFA)**
- Enforce phishing-resistant MFA (FIDO2, Windows Hello for Business)
- Require MFA for all Key Vault access operations
- Review and strengthen conditional access policies

### Short-term Actions (Priority 2)

4. **Segmentation and Access Boundaries**
- Separate production and non-production Key Vault access
- Create dedicated service principals for application access
- Implement network segmentation with Private Endpoints

5. **Key Rotation and Secrets Management**
- Implement automated key rotation policies
- Audit all keys/secrets stored in accessible vaults
- Migrate to managed identities where possible

6. **Audit and Compliance**
- Conduct full access review for all users with Key Vault permissions
- Document legitimate business justifications for access
- Implement quarterly access recertification

### Long-term Actions (Priority 3)

7. **Zero Trust Architecture**
- Implement identity-based access with continuous verification
- Deploy Azure Key Vault firewall rules
- Enable Key Vault soft delete and purge protection

8. **Security Posture Improvement**
- Implement break-glass emergency access procedures
- Create security playbooks for compromised account scenarios
- Conduct regular penetration testing focusing on high-privilege accounts

---

## Conclusion

Alberto Polak's account represents a **critical security risk** due to extensive access to 33 Azure Key Vaults across the infrastructure. The blast radius analysis reveals that a single account compromise could expose the entire organization's cryptographic keys, secrets, and certificates.

**Immediate remediation is strongly recommended** to reduce the attack surface and implement defense-in-depth security controls.
