# Cloud Infrastructure Security Assessment: What to Measure and How to Fix It

A cloud infrastructure security assessment is a systematic evaluation of your cloud environment's security configuration against established best practices and your own security policy. The goal is a clear picture of your actual security posture - not the posture you assume you have based on your last configuration, but what's actually deployed and running right now.

This guide covers what to measure, how to measure it, and critically - what to do with the results.

## What a Security Assessment Should Cover

A comprehensive cloud infrastructure security assessment evaluates five layers:

| Layer | What's Assessed | Common Findings |
|---|---|---|
| Identity (IAM) | Permission scope, MFA, access keys | Overprivileged roles, root account usage, old access keys |
| Compute | Instance configurations, OS patching, security groups | Open ports, unpatched OS, public IPs |
| Network | VPC design, routing, firewall rules | Overly permissive security groups, public subnets |
| Storage | Encryption, access control, public access | Public S3 buckets, unencrypted EBS, S3 without logging |
| Logging & Monitoring | CloudTrail, GuardDuty, CloudWatch | Missing logging, GuardDuty disabled, no alerts |

## Running the Assessment

### Method 1: Manual Review

Qualified security engineers manually inspect configuration across each layer. This provides the deepest context and catches nuanced issues, but is time-intensive and can't be sustained continuously.

### Method 2: Automated CSPM Scanning

CSPM tools like Dedups.ai connect to your AWS account via IAM role and systematically evaluate configurations against hundreds of security checks. This is fast, comprehensive, and repeatable - and unlike manual review, it can run continuously.

### Method 3: Hybrid Approach

Automated continuous scanning catches the majority of misconfigurations continuously. Manual review supplements for high-risk areas, new services being adopted, and complex IAM configurations where context matters.

## Reading and Prioritizing Results

A typical initial assessment of a mid-sized AWS environment generates 50–500 findings. Addressing them all simultaneously isn't practical - you need a prioritization framework.

**Priority 1 - Fix immediately:**
- Public S3 buckets containing sensitive data
- Security groups with 0.0.0.0/0 on port 22 or 3389 (SSH/RDP)
- IAM users with administrative permissions and no MFA
- GuardDuty disabled in any region
- Resources with public IP access that should be private

**Priority 2 - Fix this sprint:**
- Unencrypted storage volumes
- Missing CloudTrail logging in any region
- Overly permissive IAM roles (not minimum privilege)
- S3 bucket logging disabled
- Security groups with unnecessarily broad access

**Priority 3 - Fix this quarter:**
- Tagging compliance gaps
- Older TLS versions in use
- Non-critical best practice deviations

## From Assessment to Remediation

Assessment findings that don't result in remediation are expensive documents of your risk, not actual security improvements. Building a remediation workflow is as important as the assessment itself.

Dedups.ai is designed around this principle. Every finding includes:
- **Context**: Why this is a risk and what the impact is
- **Remediation steps**: Exactly what change needs to be made
- **Blast radius**: What other resources might be affected
- **Routing**: The finding goes to the team responsible for the resource

The platform supports dry-run previews (see what will change before it changes), scheduled remediations (fix during your maintenance window), and evidence collection (timestamped record of what was fixed and when).

## Compliance Evidence From Your Assessment

For teams working toward SOC 2, ISO 27001, PCI-DSS, or HIPAA, your assessment process needs to generate compliance-ready evidence:

- **Scope**: Which systems were assessed
- **Methodology**: What checks were performed
- **Findings**: What was found and its severity
- **Remediation**: What was fixed and when
- **Residual risk**: What remains and why it's accepted

Dedups.ai generates this evidence trail automatically as part of the continuous assessment and remediation process, eliminating the last-minute documentation scramble before audits.

## Scheduling Ongoing Assessments

A one-time assessment is a point-in-time snapshot. Cloud environments change continuously - new resources are provisioned, configurations drift, new services are adopted. Continuous assessment means your security posture is measured in real-time, not quarterly.

Dedups.ai runs continuous assessments against your AWS environment, flagging new misconfigurations within hours of their creation - before they've been exploited.
