# Blast Radius Report: Alberto Polak

## Executive Summary

This report analyzes the blast radius of **Alberto Polak**, identifying all entities that could be impacted if this user account is compromised. The analysis reveals that Alberto Polak has direct permissions to **33 Azure Key Vaults** across multiple resource groups, representing a significant security exposure.

**Key Findings:**
- **Total Entities at Risk:** 33 Azure Key Vaults
- **Path Distance:** All entities are directly accessible (1-hop)
- **Edge Type:** "has permissions to" for all resources
- **Known Vulnerabilities:** None detected across all entities
- **Criticality Score:** 0 (baseline) for all entities

---

## Risk Classification Methodology

Entities are ranked based on the following risk factors:
1. **Production Environment Indicators** - Resources with "prod" naming
2. **Critical Workload Indicators** - Services like AI, MDC (Microsoft Defender for Cloud), Sentinel
3. **Firewall & Security Infrastructure** - Resources with "fw-cert" or security-related naming
4. **Core Identity & Authentication** - Resources related to identity management
5. **General Production Resources** - Other production or sensitive workloads
6. **Development & Testing Resources** - Lower-risk dev/test environments

- **Lateral Movement Risk:** Direct access to all resources (no chaining required)

---

## Security Recommendations

### Immediate Actions (Priority 1)

1. **Review and Audit Permissions**
- Conduct immediate audit of Alberto Polak's access requirements
- Remove permissions to Key Vaults not required for current role
- Implement least privilege access model

2. **Enable Multi-Factor Authentication (MFA)**
- Enforce MFA for this high-privilege account
- Consider implementing phishing-resistant MFA (FIDO2/Windows Hello)

3. **Implement Conditional Access**
- Restrict access to trusted devices only
- Implement location-based access policies
- Require compliant device state

### Short-term Actions (Priority 2)

4. **Segregate Production and Non-Production Access**
- Create separate accounts for production vs. development access
- Implement Just-In-Time (JIT) access for production Key Vaults
- Use Azure PIM (Privileged Identity Management) for elevation

5. **Enhanced Monitoring**
- Enable Azure Key Vault logging for all accessed vaults
- Configure alerts for unusual access patterns
- Implement Microsoft Sentinel detection rules for this account

6. **Break Glass Account Review**
- If this is a break-glass account, ensure proper controls are in place
- Rotate credentials regularly
- Implement secure credential storage

### Long-term Actions (Priority 3)

7. **Implement Service Principals**
- Migrate automation tasks to service principals with limited scope
- Reduce dependency on user accounts for system operations

8. **Regular Access Reviews**
- Implement quarterly access certification process
- Automated deprovisioning for unused permissions
- Track permission usage analytics

9. **Zero Trust Architecture**
- Implement continuous verification for all access requests
- Move towards workload identity federation where possible
- Implement network microsegmentation

---

## Conclusion

Alberto Polak represents a **significant security risk** with direct permissions to 33 Azure Key Vaults spanning production, security infrastructure, AI services, and identity management systems. The broad scope of access creates a large blast radius where a single compromised credential could impact:

- Production services and deployments
- Security monitoring and defense systems
- Identity and authentication infrastructure
- AI and modern workplace applications
- Financial and HR systems (payroll)

**Risk Score:** HIGH - Immediate attention required

The principle of least privilege should be applied urgently to reduce this blast radius. Consider implementing role-based access control (RBAC), Just-In-Time access, and proper segregation between production and non-production environments.
