Description
What is it?
Cloud Infrastructure Vulnerability Assessment (Cloud Infra VA) is a process of identifying and evaluating security weaknesses or vulnerabilities within your cloud-based infrastructure. This includes virtual machines, containers, storage buckets, network configurations, and any other resources deployed in your cloud environment (AWS, Azure, GCP, etc.). The goal is to proactively find and remediate potential security risks that could be exploited by malicious actors to gain unauthorized access, steal data, or disrupt operations.
Technical Data
How to do it? | |
---|---|
Define the Scope | Clearly identify which cloud resources and services are included in the assessment. |
Consider factors like criticality, sensitivity of data, and potential impact of a breach. | |
Gather Information | Collect details about your cloud infrastructure, including configurations, network topology, access controls, and security policies. Leverage cloud provider tools and APIs for automated data gathering. |
Automated Scanning | Employ cloud security posture management (CSPM) tools or vulnerability scanners specifically designed for cloud environments. These tools often: |
Check for Misconfigurations | Identify insecure settings like open ports, overly permissive access controls, or unencrypted data storage. |
Scan for Vulnerabilities | Search for known vulnerabilities in operating systems, software components, and cloud services based on vulnerability databases. |
Assess Compliance | Check if your cloud infrastructure adheres to industry standards and regulatory requirements (e.g., CIS Benchmarks, PCI DSS, HIPAA). |
Manual Review | Supplement automated scans with manual reviews by security experts to identify configuration drift, logic flaws, or other vulnerabilities that automated tools might miss. |
Analyze Results | Carefully review the scan results and manual findings. Understand the severity and potential impact of each vulnerability. |
Prioritize Remediation | Based on the criticality of vulnerabilities, prioritize which ones to address first. |
Remediate | Take necessary actions to fix the identified vulnerabilities: |
Apply Patches | Update operating systems, software components, and cloud services to their latest secure versions. |
Reconfigure | Correct misconfigurations in access controls, network settings, and storage permissions. |
Apply Security Best Practices | Implement cloud provider-specific security recommendations and industry best practices. |
Software Used | |
Cloud Security Posture Management (CSPM) Tools | |
Prisma Cloud | Offers comprehensive cloud security and compliance capabilities. |
CloudGuard | Provides cloud security posture management and threat detection. |
Orca Security | Agentless cloud security platform with a focus on visibility and vulnerability management. |
Lacework | Delivers cloud security analytics and threat detection. |
Cloud-Native Vulnerability Scanners | |

Azure Security Center | Offers built-in vulnerability scanning for Azure resources. |
Google Cloud Security Command Center | Provides vulnerability scanning and threat detection for Google Cloud resources. |
Other Tools | |
Nessus | A popular vulnerability scanner that can be adapted for cloud environments. |
OpenVAS | An open-source vulnerability scanner that can be used for cloud infrastructure assessments. |
Cloud-Specific Tools | Several cloud providers offer additional tools for security and compliance assessments (e.g., AWS Config, Azure Advisor). |
Standards for Testing | |
CIS Benchmarks | Provide detailed security configuration guidelines for various cloud platforms and services. |
NIST Cybersecurity Framework | Offers a comprehensive framework for managing and reducing cybersecurity risk. |
Cloud Security Alliance (CSA) Cloud Controls Matrix (CCM) | Defines a set of security controls for cloud environments. |
Industry-Specific Standards | PCI DSS, HIPAA, GDPR, etc., may have specific requirements for cloud security. |
Key Points | |
Cloud-Specific Risks | Cloud environments have unique security challenges, such as misconfigurations, shared responsibility models, and dynamic infrastructure changes. |
Continuous Monitoring | Cloud environments change rapidly, so continuous vulnerability assessment and monitoring are crucial. |
Automation | Leverage automation wherever possible to streamline assessments and keep up with the dynamic nature of cloud environments. |
Shared Responsibility | Understand the shared responsibility model between you and your cloud provider for security. |
