Cloud Security Alliance Updated CCSK Exam Questions and Answers by aras

The Detection and Analysis phase involves identifying incidents and determining their impact. It is crucial to validate events to understand if they constitute a security incident. Reference: [Security Guidance v5, Domain 11 - Incident Response]

Cascading log architecture enables centralized collection of logs from various sources, enhancing visibility and simplifying security monitoring in hybrid environments. Reference: [Security Guidance v5, Domain 6 - Security Monitoring]

Serverless functions are designed to run in isolated, ephemeral environments, meaning that each execution is independent and temporary. These functions are typically event-driven and executed on-demand, without the need for pre-allocated server resources. Once the function finishes executing, the environment is discarded, making it highly efficient and scalable. This architecture abstracts away infrastructure management, allowing developers to focus on the code itself.

A centralized bastion or transit network improves hybrid cloud security by:

Reducing cloud sprawl through a unified security control point.

Centralizing firewall, logging, and security monitoring for better threat detection and response.

Enforcing consistent security policies across different cloud platforms (AWS, Azure, on-premises data centers).

Minimizing unauthorized lateral movement within hybrid cloud environments.

This concept is extensively covered in:

CCSK v5 - Security Guidance v4.0, Domain 7 (Infrastructure Security)

Cloud Controls Matrix (CCM) - Network Security and Monitoring​.
