Understanding Public Cloud Security Challenges

Belgian organizations leveraging AWS, Azure, or Google Cloud Platform face unique security challenges that differ fundamentally from traditional on-premises infrastructure security. The shared responsibility model divides security obligations between cloud providers and customers, with providers securing the underlying infrastructure while customers remain responsible for securing their data, applications, identities, and configurations. This division frequently creates confusion, leading to security gaps when organizations assume providers handle aspects that remain customer responsibilities.
Cloud environments’ dynamic nature presents additional challenges. Resources can be provisioned rapidly through self-service portals, infrastructure-as-code deployments, or automated scaling mechanisms. This agility enables business innovation but creates security visibility challenges as shadow IT proliferates and misconfigurations multiply. Belgian enterprises must implement systematic security assessment and monitoring capabilities that keep pace with cloud environment changes.
The complexity of cloud platforms compounds security challenges. AWS alone offers hundreds of services, each with distinct security configurations, access controls, and monitoring requirements. Azure and Google Cloud Platform present similar complexity. Belgian organizations typically use multiple cloud platforms—adopting multi-cloud strategies to avoid vendor lock-in, leverage best-of-breed services, or support acquired companies’ existing infrastructure—further multiplying security management complexity.
Vulnerabilities

Common Cloud Security Vulnerabilities Across AWS, Azure, and GCP

Public cloud security assessments consistently uncover similar vulnerability patterns across all major platforms. Understanding these common security issues helps Belgian organizations recognize risks and implement effective preventive measures.

Storage Misconfigurations

Publicly accessible storage buckets represent one of the most prevalent and dangerous cloud security vulnerabilities. AWS S3 buckets, Azure Blob Storage containers, and Google Cloud Storage buckets misconfigured to allow public access have caused numerous high-profile data breaches. Assessments identify storage resources with overly permissive access controls, missing encryption configurations, inadequate logging, and lack of versioning for ransomware protection. For Belgian companies storing customer data, financial records, or intellectual property in cloud storage, proper access controls are fundamental.

Identity and Access Management Weaknesses

Excessive permissions and poor identity governance create significant security risks across cloud platforms. Common issues include overly broad IAM policies granting unnecessary permissions, long-lived access keys creating credential compromise risks, lack of multi-factor authentication for privileged accounts, excessive use of root or administrator accounts, and inadequate separation of duties. Assessments evaluate IAM configurations across AWS IAM, Azure Active Directory, and Google Cloud IAM, identifying privilege escalation paths and access control weaknesses.

Network Security Gaps

Improperly configured network controls expose cloud resources to unauthorized access. Vulnerabilities include security groups or firewall rules allowing unrestricted inbound access, missing network segmentation between environments, lack of private connectivity for sensitive services, exposed management interfaces, and inadequate logging of network traffic. Belgian organizations must implement defense-in-depth network security aligned with data sensitivity and compliance requirements.

Encryption Deficiencies

Inadequate encryption leaves data vulnerable to unauthorized access. Common issues include unencrypted storage volumes and databases, lack of encryption in transit, poor key management practices, use of default encryption keys instead of customer-managed keys, and missing encryption for backup data. Assessments identify encryption gaps across compute, storage, and database services. For Belgian enterprises subject to GDPR encryption requirements, systematic encryption implementation is essential.

Logging and Monitoring Gaps

Insufficient visibility into cloud environments prevents detecting security incidents and investigating breaches. Vulnerabilities include disabled or incomplete logging across cloud services, inadequate log retention violating compliance requirements, lack of centralized log aggregation, missing security monitoring and alerting, and insufficient integration with Security Operations Centers. Belgian organizations required to detect incidents within 72 hours under GDPR must implement comprehensive cloud monitoring.

Compliance Violations

Cloud resources frequently violate regulatory and internal compliance requirements. Issues include resources deployed in unapproved geographic regions violating data residency requirements, missing compliance tags for resource tracking, lack of required backup configurations, inadequate patch management for virtual machines, and missing security baseline implementations. Assessments identify compliance violations across platforms, enabling remediation before regulatory audits.

Container and Serverless Security Issues

Organizations adopting modern cloud-native architectures face additional security challenges. Vulnerabilities include container images with known vulnerabilities, excessive permissions for serverless functions, missing runtime protection for containers, inadequate secrets management, and lack of supply chain security for third-party components. Belgian companies embracing containerization and serverless computing must extend security assessments to these modern workloads.

Resource Sprawl and Shadow IT

Unmanaged cloud resource proliferation creates security blind spots. Assessments discover forgotten development environments, orphaned resources no longer serving business purposes, shadow IT deployments bypassing security review, and excessive spending on unused resources. Systematic inventory and governance prevent security gaps from unmanaged infrastructure.

Cloud Management

Cloud Security Posture Management (CSPM) Explained

  • Cloud Security Posture Management represents an evolution beyond periodic security assessments, providing continuous monitoring and automated remediation of cloud security risks. CSPM solutions integrate with AWS, Azure, and Google Cloud Platform through APIs, continuously scanning cloud configurations against security best practices, compliance frameworks, and organizational policies.
  • CSPM platforms deliver several critical capabilities for Belgian enterprises. They provide real-time visibility into security posture across multi-cloud environments, automatically detect misconfigurations as resources are created or modified, assess compliance against frameworks including ISO 27001, CIS benchmarks, and GDPR requirements, prioritize risks based on severity and exploitability, and enable automated remediation of common security issues. For organizations managing complex multi-cloud environments, CSPM solutions provide centralized security visibility and control that manual processes cannot achieve.
  • Leading CSPM platforms include cloud-native solutions like AWS Security Hub, Azure Security Center, and Google Cloud Security Command Center, as well as third-party platforms like Palo Alto Prisma Cloud, Wiz, and Orca Security offering unified multi-cloud visibility. Belgian organizations should evaluate CSPM solutions based on multi-cloud support requirements, compliance framework coverage, integration capabilities, and automation features.
Methodology

Comprehensive Cloud Security Assessment Methodology

Systematic cloud security assessments follow structured methodologies ensuring thorough coverage across cloud platforms. Belgian organizations should implement repeatable assessment processes that can be executed regularly to maintain visibility into evolving cloud environments.

This includes identifying compute instances, storage resources, databases, networking components, serverless functions, container clusters, and identity resources. For Belgian enterprises with distributed cloud adoption across business units, complete asset discovery often reveals shadow IT and forgotten resources creating security risks.

Identity and Access Management Review

Detailed examination of IAM configurations identifies excessive permissions and access control weaknesses. Assessors analyze IAM policies and role assignments, review service account and application permissions, identify overly privileged access, evaluate multi-factor authentication enforcement, assess privileged access management, and analyze cross-account or cross-tenant access patterns. Strong identity governance prevents unauthorized access and limits breach impact.

Network Security Architecture Assessment

Evaluating network configurations identifies exposure risks and segmentation gaps. Assessments review security group and firewall rules, analyze network segmentation and isolation, evaluate public exposure of resources, assess VPN and private connectivity, review load balancer and API gateway security, and analyze network flow logs. Belgian organizations must implement network security aligned with data classification and threat models.

Data Protection and Encryption Analysis

Systematic evaluation of data security controls identifies encryption gaps and data exposure risks. Assessors identify unencrypted storage and databases, review encryption in transit configurations, evaluate key management practices, assess backup and disaster recovery security, analyze data classification implementation, and identify data residency compliance issues. For Belgian companies handling personal data under GDPR, comprehensive data protection is mandatory.

Compute Security Review

Examining compute resources identifies vulnerable systems and configuration weaknesses. Assessments evaluate virtual machine security baselines, analyze patch management implementation, review container security configurations, assess serverless function permissions, identify outdated or vulnerable operating systems, and evaluate endpoint protection deployment. Secure compute foundations prevent exploitation of application and system vulnerabilities.

Logging, Monitoring, and Incident Response Evaluation

Analyzing security visibility capabilities identifies detection gaps and response deficiencies. Assessors review logging configurations across services, evaluate log retention and compliance, assess security monitoring and alerting, analyze SIEM integration, evaluate incident response procedures, and identify visibility gaps. Belgian organizations must detect and respond to security incidents rapidly to meet regulatory obligations.

Compliance and Governance Assessment

Evaluating compliance controls ensures regulatory requirements are met. Assessments review compliance with GDPR requirements including data residency, analyze adherence to industry frameworks like ISO 27001, evaluate resource tagging and cost allocation, assess backup and disaster recovery compliance, review security baseline implementation, and identify governance gaps. Belgian enterprises in regulated industries require documented compliance aligned with sector-specific requirements.

Security Improvements

Implementing Cloud Security Improvements

Identifying vulnerabilities provides value only when followed by systematic remediation. Belgian organizations should implement structured improvement programs addressing assessment findings across cloud platforms.

Identity Security Hardening

Strengthening cloud identity security prevents unauthorized access. Belgian companies should implement least privilege access across all platforms, enforce multi-factor authentication for all cloud accounts, eliminate long-lived access keys replacing with temporary credentials, implement just-in-time privileged access, regularly review and remove excessive permissions, and deploy privileged access workstations for cloud administration. Strong identity controls form the foundation of cloud security.

Network Segmentation and Micro-segmentation

Implementing defense-in-depth network security limits lateral movement and blast radius. Organizations should segment production from non-production environments, isolate sensitive workloads in dedicated networks, implement zero-trust network architectures, restrict public exposure to necessary services only, deploy web application firewalls protecting internet-facing applications, and implement network flow monitoring. Proper segmentation contains breaches and limits damage potential.

Encryption and Key Management

Comprehensive encryption protects data confidentiality across cloud platforms. Belgian enterprises should enable encryption at rest for all storage and databases, implement encryption in transit using TLS protocols, deploy customer-managed encryption keys for sensitive data, implement proper key rotation procedures, encrypt backup data and snapshots, and document encryption practices for compliance. Systematic encryption implementation demonstrates GDPR compliance and protects against unauthorized data access.

Security Monitoring and SIEM Integration

Implementing comprehensive monitoring enables rapid threat detection. Organizations should enable detailed logging across cloud services, implement centralized log aggregation and analysis, integrate cloud logs with Security Information and Event Management platforms, configure security alerts for suspicious activities, deploy cloud-native security monitoring tools, and establish security operations procedures. For Belgian companies required to detect breaches rapidly, robust monitoring is essential.

Automated Compliance and Remediation

Leveraging automation accelerates security operations and maintains compliance. Belgian companies should implement infrastructure-as-code with security testing, deploy CSPM solutions for continuous monitoring, configure automated remediation for common misconfigurations, implement policy-as-code enforcing security baselines, establish guardrails preventing risky deployments, and automate compliance reporting. Automation scales security operations across growing cloud environments.

Backup and Disaster Recovery

Implementing resilient backup strategies protects against ransomware and data loss. Organizations should configure automated backups for critical data, implement immutable backups preventing ransomware encryption, store backups in separate accounts or regions, regularly test recovery procedures, document disaster recovery runbooks, and establish recovery time objectives. Independent backups provide insurance against destructive attacks and accidental deletion.

Security Measures

CSPM Implementation Best Practices

Custom policies may be necessary for internal security requirements or Belgian regulatory obligations not covered by standard frameworks.

Risk Prioritization

CSPM solutions typically identify thousands of potential security issues across cloud environments. Belgian organizations should configure risk scoring aligned with organizational priorities, contextualizing findings based on data sensitivity, environment criticality, and exploitability. Prioritized remediation focuses resources on issues posing greatest actual risk rather than treating all findings equally.

Automated Remediation with Guardrails

While automated remediation accelerates security operations, organizations should implement carefully to avoid operational disruptions. Belgian companies should begin with monitoring and alerting, gradually enabling automated remediation for low-risk issues, implement approval workflows for high-impact changes, and maintain manual review for production environment modifications. Balanced automation improves security without compromising stability.

Integration with DevOps Workflows

Shifting security left by integrating CSPM with development pipelines prevents security issues before production deployment. Organizations should implement infrastructure-as-code scanning, integrate security checks in CI/CD pipelines, provide developer feedback on security issues, establish security gates preventing risky deployments, and foster collaboration between security and development teams. DevSecOps integration embeds security throughout cloud lifecycle.
