Cloud environments are misconfigured more often than they're attacked by sophisticated threats. With 55% of cloud breaches tracing back to misconfigurations, regular security assessments are essential for identifying gaps before attackers do.
The Cloud Security Challenge
Cloud security differs fundamentally from traditional security:
- 99% of cloud breaches result from preventable misconfigurations (Gartner)
- 55% of breaches trace back to misconfigurations, not sophisticated attacks
- 31% of APIs still lack HTTPS encryption
- Average cloud breach cost: $4.45 million
You secure your configurations. The cloud provider secures their infrastructure. Understanding this division is critical.
Shared Responsibility Model
📚 Cloud Shared Responsibility Model: Who secures what.
| Layer | You Secure | Provider Secures |
|---|---|---|
| Physical | - | Data centers, hardware |
| Network | Security groups, NACLs | Physical network |
| Compute | OS config, patching | Hypervisor, host OS |
| Identity | IAM policies, users | Identity infrastructure |
| Data | Encryption, access | Storage infrastructure |
| Application | Code, dependencies | Managed services |
The gap: Misconfigured security groups, overly permissive IAM policies, and public storage buckets are YOUR responsibility.

- Public exposure
- VPC/VNet architecture
- Egress controls
3. Data Protection
- Encryption at rest
- Encryption in transit
- Key management
- Data classification
- Backup security
4. Logging and Monitoring
- Audit logging enabled
- Log centralization
- Alerting configuration
- Retention policies
- Threat detection
5. Compliance
- CIS Benchmark alignment
- Framework compliance (NIST, ISO 27001)
- Industry regulations (HIPAA, PCI-DSS)
- Policy enforcement
Cloud Security Posture Management (CSPM)
📚 What Is CSPM?: Cloud Security Posture Management explained.
CSPM tools continuously monitor for misconfigurations:
What CSPM Does
- Continuous scanning across cloud environments
- Compliance checking against benchmarks and frameworks
- Risk prioritization based on exposure and impact
- Remediation guidance with automated fixes
- Multi-cloud visibility from a single console
CSPM Options
| Category | Options | Best For |
|---|---|---|
| Dedicated CSPM | Wiz, Orca, Prisma Cloud, Lacework | Multi-cloud, advanced features |
| AWS Native | Security Hub, GuardDuty, Config | AWS-only environments |
| Azure Native | Defender for Cloud, Security Center | Azure-only environments |
| GCP Native | Security Command Center | GCP-only environments |
When to Use CSPM vs Assessment
- CSPM: Continuous, automated, configuration-focused
- Assessment: Periodic, comprehensive, context-rich
- Best approach: Use both—CSPM for ongoing monitoring, assessments for deep analysis

Best Practices
Before Assessment
- Document your environment - Account structure, services used
- Identify stakeholders - Security, DevOps, compliance teams
- Define scope - Which accounts, regions, services
- Establish baseline - Current known issues
- Plan remediation resources - Who will fix findings
During Assessment
- Ensure access - Read-only permissions for assessors
- Stay engaged - Answer questions promptly
- Document exceptions - Known acceptable risks
- Track progress - Monitor assessment completion
After Assessment
- Prioritize ruthlessly - Focus on critical and high first
- Create tickets - Track remediation in your system
- Set deadlines - Assign owners and due dates
- Verify fixes - Rescan after remediation
- Communicate progress - Report to leadership
Conclusion
Cloud security assessment identifies misconfigurations before they become breaches:
- Assess regularly - At least annually, more for high-risk environments
- Combine approaches - CSPM for continuous, assessments for depth
- Cover all providers - AWS, Azure, GCP have different security models
- Act on findings - Assessment value comes from remediation
- Track progress - Measure improvement over time
The goal isn't a perfect score—it's continuous improvement. Each assessment should find fewer critical issues than the last. Build a culture of cloud security hygiene, and misconfigurations become rare rather than routine.
Your cloud is only as secure as your configurations. Regular assessment ensures those configurations protect rather than expose your data.
