Understanding the core concepts, models, and challenges of securing cloud environments.
What is Cloud Security? Cloud Security encompasses the set of policies, controls, procedures, and technologies that work together to protect cloud-based systems, data, and infrastructure from threats.
Core Concepts
- Cloud Security Architecture: Designing secure cloud environments using principles like least privilege, defense in depth, and secure network segmentation (VPCs/VNets).
- Identity and Access Management (IAM): Managing user identities, roles, and permissions to control access to cloud resources securely.
- Data Encryption & Compliance: Protecting data at rest and in transit using encryption, managing keys, and adhering to relevant compliance standards (GDPR, HIPAA, etc.).
- Cloud Incident Response: Adapting traditional incident response processes for cloud environments, including log analysis, forensics, and automated response actions.
Fundamental Cheatsheets & Guides
Native cloud provider tools and third-party solutions for securing cloud environments.
Identity & Access Management (IAM)
AWS IAM
Manage user access and permissions securely for AWS services and resources.
Azure AD (Entra ID)
Microsoft's cloud-based identity and access management service (now part of Microsoft Entra).
Google Cloud IAM
Provides fine-grained access control and visibility for managing Google Cloud resources centrally.
Threat Detection & Monitoring
Amazon GuardDuty
Intelligent threat detection service that continuously monitors for malicious activity and unauthorized behavior in AWS.
Defender for Cloud
Unified infrastructure security management system (CSPM & CWPP) for Azure, on-premises, and multi-cloud resources.
Security Command Center
Centralized security and risk management platform for Google Cloud, providing visibility and control.
Prowler
Open source tool for AWS, Azure, GCP security assessment, auditing, hardening and incident response.
View RepoCompliance & Governance
CSA STAR Registry
Publicly accessible registry documenting the security and privacy controls provided by popular cloud computing offerings.
AWS Config
Service enabling assessment, auditing, and evaluation of the configurations of AWS resources.
Azure Policy
Helps enforce organizational standards and assess compliance at-scale for Azure resources.
Platforms offering labs and scenarios to practice cloud security skills.
Cloud Security Labs & Challenges
- Flaws.cloud / Flaws2.cloud: Series of levels involving exploiting AWS security misconfigurations.
- Hack The Box Cloud Labs: Offers dedicated cloud hacking challenges and labs.
- AWS Security Workshops: Hands-on labs often utilizing Security Hub and other AWS security services.
- CloudGoat: Rhino Security Labs' "Vulnerable by Design" AWS deployment tool.
Certification-Focused Labs
Many certification training providers offer hands-on labs as part of their courses.
- AWS Certified Security – Specialty: Look for official AWS training or third-party providers like A Cloud Guru, Whizlabs.
- Azure Security Engineer Associate (AZ-500): Utilize Microsoft Learn sandboxes and labs from training partners.
- Google Professional Cloud Security Engineer: Practice with Google Cloud Skills Boost (formerly Qwiklabs) and partner training.
Examples of how cloud security principles and tools are applied in practice.
Enterprise Cloud Security Posture
- Securing cloud workloads (VMs, containers, serverless functions) and applications deployed in the cloud.
- Implementing zero-trust security models where trust is never assumed, and verification is required from everyone trying to gain access.
- Utilizing CSPM tools to continuously monitor for misconfigurations and compliance violations.
Cloud Forensics & Incident Response
- Investigating security incidents and potential breaches occurring within cloud environments.
- Performing forensic analysis of cloud provider logs (e.g., AWS CloudTrail, Azure Monitor Logs, Google Cloud Logging) and activity data.
Cloud Compliance & Governance
- Ensuring cloud deployments meet industry and regulatory compliance standards (e.g., GDPR, HIPAA, SOC 2, PCI DSS).
- Automating the enforcement of security policies and configurations using Infrastructure as Code (IaC) and Policy as Code tools.
