Cloud Native Security encompasses a comprehensive approach to protecting containerized environments and microservices architectures. The 4Cs of Cloud Native Security framework provides a structured methodology for implementing security across multiple layers, starting from the cloud infrastructure foundation and extending through to application code. Cloud providers and infrastructure security form the foundational layer, requiring organizations to understand shared responsibility models and leverage provider-native security tools. Controls and frameworks establish standardized security policies and compliance requirements, while isolation techniques such as network...

Topic 1 : Overview of Cloud Native Security
Q1
In a Kubernetes environment, what kind of Admission Controller can modify resource manifests when applied to the Kubernetes API to fix misconfigurations automatically?
Topic Content
Kubernetes Cluster Component Security encompasses the protection and hardening of all critical infrastructure elements within a Kubernetes environment. This includes securing the API Server, which serves as the central control point for cluster operations, along with the Controller Manager and Scheduler that manage cluster state and workload distribution. The Kubelet agent running on each node must be secured to prevent unauthorized container execution, while the Container Runtime requires proper isolation and access controls. Additional critical components include KubeProxy for network...

Topic 2 : Kubernetes Cluster Component Security
Q2
In order to reduce the attack surface of the Scheduler, which default parameter should be set to false?
Topic Content
Kubernetes Security Fundamentals encompasses Pod Security Standards which define baseline and restricted security policies for pod configurations, and Pod Security Admissions that enforce these standards at the cluster level. Authentication mechanisms verify user and service account identities through certificates, tokens, and external providers, while Authorization frameworks like RBAC determine what authenticated users can access and modify. Secrets management provides secure storage and retrieval of sensitive data such as passwords and API keys within the cluster. Isolation and Segmentation strategies create...

Kubernetes Threat Model encompasses the critical security vulnerabilities and attack vectors that organizations must understand to protect their containerized environments. This includes analyzing trust boundaries and data flow patterns within Kubernetes clusters to identify where unauthorized access might occur, understanding persistence mechanisms that attackers use to maintain long-term access to compromised systems, and recognizing denial of service attacks that can disrupt cluster availability. Additionally, it covers the risks of malicious code execution and compromised applications running within containers, threats posed...

Platform Security encompasses the foundational mechanisms and practices required to protect containerized environments and cloud-native infrastructure. Supply Chain Security ensures that all software components and dependencies are verified and trusted from source to deployment, preventing unauthorized or compromised code from entering the system. Image Repository management involves securing container images through proper storage, access controls, and vulnerability scanning to maintain the integrity of deployable artifacts. Observability provides visibility into system behavior, security events, and anomalies through comprehensive logging, monitoring, and...

Compliance and Security Frameworks encompass the essential structures and methodologies organizations implement to protect their assets and maintain regulatory adherence. Compliance Frameworks establish the foundational standards and requirements that organizations must follow to meet legal, regulatory, and industry-specific obligations, ensuring consistent security practices across all operations. Threat Modelling Frameworks provide systematic approaches to identify, analyze, and prioritize potential security risks and vulnerabilities within systems and applications before they can be exploited. Supply Chain Compliance addresses the security and regulatory requirements...
