# Best Practices: Proactive Cloud Attack Surface Management using Risk Context
## Overview
These practices focus on proactively managing and reducing the cloud attack surface by identifying "toxic combinations" of interconnected risks (e.g., network exposure, sensitive data, excessive permissions) that create critical attack paths, rather than focusing solely on standalone vulnerabilities.
## Key Recommendations
### Immediate Actions
1. **Identify Existing Toxic Combinations:** Immediately leverage existing security tools' context or visualizations to map resources with high-risk factors (e.g., public exposure, PII/sensitive data, critical vulnerabilities) to identify any immediate, high-severity attack paths.
2. **Prioritize Based on Context:** Shift immediate remediation focus from the sheer number of individual vulnerabilities to the small set of interconnected issues (toxic combinations) that represent immediate, exploitable paths to critical assets.
### Short-term Improvements (1-3 months)
1. **Deploy Agentless Visibility:** Implement an agentless cloud security solution to achieve comprehensive, full-stack visibility across all cloud assets (VMs, containers, serverless, AI services) without deployment overhead or blind spots inherent in agent-based scanning.
2. **Implement Security Graph Analysis:** Begin using capabilities that surface relationships between cloud components (Security Graph) to visualize and analyze attack paths, moving beyond isolated risk alerts.
3. **Define "Critical Issues":** Establish an internal definition for a "Critical Wiz Issue" equivalent: an issue combining High Likelihood of Compromise + Significant Business Impact, and set a measurable goal (e.g., reducing these to zero).
### Long-term Strategy (3+ months)
1. **Achieve "Zero Criticals" Goal:** Establish and track the program to eliminate all identified critical attack paths, leveraging the context provided by graph analysis for ruthless prioritization.
2. **Democratize Remediation:** Empower infrastructure owners and development teams with the contextualized, actionable remediation guidance derived from the security graph, shifting responsibility for fixing attack paths to the relevant builders.
3. **Integrate AI Service Security Monitoring:** Ensure comprehensive agentless visibility extends seamlessly to monitor security risks associated with cloud-native AI services and data pipelines (e.g., training data exposure, model access).
## Implementation Guidance
### For Small Organizations
- **Focus on Coverage:** Prioritize rapid adoption of agentless scanning to quickly gain 100% visibility across ephemeral and unmanaged resources, maximizing coverage with minimal overhead.
- **Manual Relationship Mapping (Initial Phase):** If graph technology is inaccessible, start manually charting known critical data stores and tracing their network paths/permissions outward to identify immediate exposure points.
### For Medium Organizations
- **Tool Evaluation:** Select and implement security posture management tools that natively support Security Graph capabilities to automatically contextualize risks.
- **Establish Remediation Workflow:** Formalize the process where context-rich findings are assigned directly to infrastructure or engineering teams based on asset ownership rather than solely to the central security team.
### For Large Enterprises
- **Automated Prioritization Pipeline:** Integrate Security Graph insights directly into the ticketing/workflow systems (e.g., JIRA) to enforce priority based on interconnected risk scores.
- **Comprehensive Asset Inventory:** Ensure the agentless solution maps all services, including those related to emerging technologies (e.g., specialized AI/ML services), to prevent gaps in path tracing.
- **KPI Tracking:** Measure success by the reduction in the number of high-context critical attack paths, not just the raw count of vulnerabilities.
## Configuration Examples
*Note: The source material emphasizes tool capabilities rather than specific vendor command-line configurations. The implementation guidance below reflects the *type* of configuration achieved.*
| Risk Factor | Toxic Combination Example | Required Configuration Outcome |
| :--- | :--- | :--- |
| **Data Sensitivity + Exposure** | Database containing sensitive customer PII is accessible via an internet-facing VM. | Configure Network Security Groups/Firewalls to block ingress to the database port from the public internet; restrict access only to required internal subnets. |
| **Vulnerability + Access** | Publicly exposed VM with a known critical vulnerability (CVE) allows lateral movement. | Immediately patch the VM or isolate it via micro-segmentation if patching is delayed, ensuring the attacker cannot pivot from this entry point. |
| **Data Exposure + Write Access** | Storage bucket containing data used for AI training models allows external write access due to misconfiguration. | Enforce strict Identity and Access Management (IAM) policies ensuring only necessary roles can modify the bucket contents to prevent data poisoning or unauthorized exfiltration. |
## Compliance Alignment
- **NIST Cybersecurity Framework (CSF):** Aligns strongly with **Identify (ID)** functions (Asset Management, Risk Assessment) by providing a contextual understanding of risk.
- **ISO/IEC 27001:** Supports **A.12.1.2 (Protection against malware)** and **A.14.2 (Secure Development and Acquisition)** by ensuring security controls consider the interconnected nature of cloud systems leading to potential breaches.
- **CIS Benchmarks:** Enforcement of context-driven remediation directly aids in achieving CIS Control effectiveness by hardening the most exposed and critical paths across public cloud configurations.
## Common Pitfalls to Avoid
- **Alert Fatigue:** Do not allow security teams to become paralyzed by alerts stemming from isolated vulnerabilities that do not form part of a critical attack path.
- **Agent Deployment Hurdles:** Avoid relying solely on agent-based tooling which can miss essential visibility into ephemeral, serverless, or developer-provisioned resources.
- **Ignoring Relationships:** Treating every identified vulnerability or misconfiguration as equally urgent; this wastes time that should be spent eliminating pathways to "crown jewels."
- **Lack of Ownership:** Failing to clearly communicate remediation tasks to the infrastructure or application owners best equipped to implement the fix once the attack path context is provided.
## Resources
- **Agentless Cloud Security Solutions:** Utilize solutions that offer full-stack visibility without requiring deployment agents for comprehensive coverage.
- **Security Graph Technology:** Investigate tools that utilize graph databases/models to illustrate relationships and trace attack paths rather than just inventorying assets.
- **"Zero Criticals" Methodology:** Adopt a process focused on ruthlessly prioritizing and eliminating high-context, exploitable attack paths to drive measurable security posture improvement.
