Misconfiguration is one of the most prevalent risks in serverless and container-based environments. Given the complex nature of container orchestration (e.g., Kubernetes), CI/CD pipelines, and ephemeral infrastructure, simple missteps—such as overly permissive roles or exposed ports—can lead to significant vulnerabilities.

These workloads require strict configuration management, automated scanning, and secure defaults to prevent breaches. Unlike traditional servers, containers and functions spin up and down rapidly, making traditional visibility tools insufficient.

This is discussed thoroughly inDomain 8: Virtualization and Containers, where the CCSK guidance identifies misconfiguration as a leading cause of cloud-native exploitation.

The Preparation phase focuses on setting up an incident response team and developing plans to handle incidents efficiently when they occur. Reference: [Security Guidance v5, Domain 11 - Incident Response]

In the Infrastructure as a Service (IaaS) shared responsibility model, the Cloud Service Provider (CSP) is typically responsible for securing the physical infrastructure, which includes the physical security of data centers, servers, networking hardware, and the physical security controls that protect them from unauthorized access or damage.

Encrypting data at rest is typically the responsibility of the consumer, though the CSP may offer tools to help with this. Managing application code is the responsibility of the consumer, as they control and deploy the applications on the infrastructure provided by the CSP. Configuring firewall rules is also the responsibility of the consumer, as they manage the configuration of the virtual network, including security rules like firewalls.

Zero Trust Network Access (ZTNA) enforces the principle of "never trust, always verify." Unlike traditional perimeter-based security, ZTNA continuously evaluates access requests using dynamic factors. These include:

User identity (authenticated via SSO or MFA)

Device posture (device compliance, health status)

Contextual information (time of access, location, behavior patterns)

This layered decision-making process ensures that access is tightly controlled and highly contextual, minimizing attack surfaces and mitigating lateral movement within networks.

ZTNA aligns with cloud-native security practices discussed inDomain 7: Infrastructure Security, emphasizing the transition from static access control lists to dynamic, identity-centric enforcement models.

A key aspect of cloud risk management is taking a structured approach to identify, assess, and address risks related to using cloud services. This includes evaluating potential risks such as security vulnerabilities, data privacy issues, service outages, and compliance challenges. Effective risk management helps organizations proactively mitigate potential threats, ensuring the cloud environment is secure, compliant, and resilient.

A structured approach for performance optimization of cloud services is more related to performance management, not risk management. A structured approach to establishing the different what/if scenarios for cloud vs on-premise decisions refers to decision-making scenarios, not the identification and management of risks. A structured approach to SWOT analysis) is a strategic planning tool that focuses on strengths, weaknesses, opportunities, and threats, but it is not specifically focused on cloud risk management.
