Question-28. How do you protect sensitive data in a multi-tenant cloud environment?
Answer-28: Through encryption, isolation, and strict access controls.
Question-29. What are the risks of using default cloud configurations?
Answer-29: Defaults often lack strong security, leaving systems vulnerable.
Question-30. How can cloud security posture management (CSPM) tools help?
Answer-30: By continuously assessing and remediating cloud security risks.
Question-31. What is the importance of API security gateways?
Answer-31: They enforce security policies for API traffic and prevent attacks.
Question-32. How does micro-segmentation improve cloud security?
Answer-32: It isolates workloads to contain breaches and limit lateral movement.
Question-33. What are some common cloud security threats?
Answer-33: Data breaches, misconfigurations, DDoS attacks, insider threats, and insecure APIs.
Question-34. Why is securing cloud storage critical?
Answer-34: Because storage often holds sensitive and valuable data vulnerable to exposure.
Question-35. How does role-based access control (RBAC) work in cloud security?

Answer-38: Techniques to prevent unauthorized data transfer or leakage.
Question-39. Why is regular penetration testing important for cloud security?
Answer-39: It identifies vulnerabilities before attackers can exploit them.
Question-40. How can encryption be applied to data in transit?
Answer-40: Using protocols like TLS/SSL to secure data moving between clients and cloud services.
Question-41. What is the significance of zero trust architecture in cloud security?
Answer-41: It assumes no user or device is trusted by default and verifies everything continuously.
Question-42. How do you secure cloud-based email services?
Answer-42: By enabling MFA, anti-phishing tools, and strong spam filters.
Question-43. What is the purpose of security groups in AWS?
Answer-43: To act as virtual firewalls controlling traffic to instances.
