Question-19. What are common compliance frameworks relevant to hybrid and multi-cloud security?
Answer-19: GDPR, HIPAA, PCI-DSS, SOC 2, and ISO 27001.
Question-20. How can organizations ensure data sovereignty in multi-cloud deployments?
Answer-20: By selecting cloud regions that comply with local regulations and applying data residency controls.
Question-21. What is cloud workload protection platform (CWPP)?
Answer-21: CWPPs provide security controls for workloads across on-premises and cloud environments.
Question-22. How do you protect against insider threats in hybrid cloud environments?
Answer-22: Through strict IAM policies, activity monitoring, anomaly detection, and least privilege access.
Question-23. What is micro-segmentation and why is it useful in hybrid clouds?
Answer-23: Micro-segmentation divides networks into granular zones to restrict access and reduce attack surfaces.
Question-24. How do hybrid clouds affect traditional perimeter-based security models?
Answer-24: They weaken perimeter defenses because resources are distributed, requiring more granular, identity-centric security.
Question-25. What role does multi-factor authentication (MFA) play in hybrid cloud security?
Answer-25: MFA adds an extra layer of security by requiring multiple forms of verification before access is granted.
Question-26. How can encryption key management be handled across multiple clouds?
Answer-26: By using centralized key management systems or cloud-agnostic Hardware Security Modules (HSMs).
Question-27. What are the risks of shadow IT in multi-cloud environments?
Answer-27: Shadow IT leads to unmanaged resources that are not secured or monitored, increasing security risks.
Question-28. How do you secure data in transit between private and public clouds?
Answer-28: By using VPNs, TLS encryption, or dedicated private links such as AWS Direct Connect or Azure ExpressRoute.
Question-29. What is Cloud Security Posture Management (CSPM)?
Answer-29: CSPM continuously monitors cloud environments for security risks and compliance violations.
Question-30. How do you implement threat intelligence sharing in hybrid clouds?
Answer-30: By integrating security tools with threat intelligence platforms and sharing indicators of compromise (IOCs).
Question-31. What is the importance of regular vulnerability assessments in multi-cloud?
Answer-31: They help identify and remediate security weaknesses before attackers can exploit them.
