Application Security in the Cloud Questions and Answers for Viva

Answer-1: Application security in the cloud refers to the measures and practices used to protect cloud-hosted applications from vulnerabilities, attacks, and data breaches.

Answer-2: Cloud environments are accessible over the internet and shared resources, making applications vulnerable to attacks if not properly secured.

Answer-3: Common threats include data breaches, insecure APIs, misconfigurations, injection attacks, and account hijacking.

Answer-4: It defines the security responsibilities between the cloud provider and the customer; providers secure the infrastructure while customers secure their applications and data.

Answer-5: By using authentication, authorization, rate limiting, input validation, and encryption of API traffic.

Answer-6: IAM manages user identities and access permissions, ensuring only authorized users can access cloud resources.

Answer-7: Identify assets, potential threats, vulnerabilities, and design mitigations specific to the cloud architecture.

Answer-8: Encryption protects data at rest and in transit, preventing unauthorized access even if data is intercepted or compromised.

Answer-9: Use managed secrets stores, avoid hardcoding secrets, rotate secrets regularly, and restrict access.

Answer-10: A WAF filters and monitors HTTP traffic to protect cloud applications from common web attacks like SQL injection and cross-site scripting.

Answer-11: Cloud-native security integrates security into the development pipeline and infrastructure automation with a focus on scalability and agility.

Answer-12: Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), and Software Composition Analysis (SCA).

Answer-13: It involves securing container images, runtime, and orchestration platforms to prevent container-specific vulnerabilities.

Answer-14: By using cloud provider DDoS protection services, rate limiting, and traffic filtering.

Answer-15: Zero trust means never trusting any request by default, continuously verifying identities and enforcing least privilege.

Answer-16: By integrating automated security testing and vulnerability scanning into the CI/CD process.

Answer-17: Logging helps detect unauthorized activities, and monitoring enables quick response to security incidents.

Answer-18: Challenges include inconsistent security policies, complex access management, and increased attack surface.

Answer-19: IaC can introduce security risks if misconfigured but also improves security by enabling automated, consistent deployments.

Answer-20: Serverless apps require securing function permissions, environment variables, and monitoring for abnormal function behaviors.

Answer-21: Regular patching fixes vulnerabilities in application components and underlying platforms.

Answer-22: By regularly scanning for vulnerabilities, using trusted sources, and applying updates promptly.

Answer-23: XSS is an injection attack; prevention includes input validation, output encoding, and using security headers.

Answer-24: Encrypt data, implement strong access controls, and regularly audit data access.

Answer-25: It means granting users and services only the minimum access necessary to perform their tasks.

Answer-26: CSPM tools continuously monitor cloud environments for misconfigurations and compliance violations.

Answer-27: Segmentation limits lateral movement in case of a breach, containing the damage.

Answer-28: By following secure coding guidelines, conducting code reviews, and integrating security testing.

Answer-29: It is a documented process to detect, respond to, and recover from security breaches affecting cloud apps.

Answer-30: Using cloud-managed Key Management Services (KMS) and limiting access to keys.

Answer-31: Misconfiguration can lead to data exposure or loss, as cloud storage might be publicly accessible.

Answer-32: Use parameterized queries, ORM frameworks, and input validation.

Answer-33: MFA adds an additional authentication layer, reducing the risk of compromised credentials.

Answer-34: By enforcing mutual TLS, using API gateways, and applying fine-grained access control.

Answer-35: Authentication verifies user identity; authorization determines what resources the user can access.

Answer-36: It protects containerized applications by managing secure deployment, scaling, and communication.

Answer-37: They offer services like WAFs, IAM, encryption, security monitoring, and compliance certifications.

Answer-38: RASP embeds security controls inside an application to detect and block attacks in real-time.

Answer-39: By providing insights into emerging threats and enabling proactive defenses.

Answer-40: Compliance ensures that applications meet regulatory security requirements to protect sensitive data.

Answer-41: By integrating security practices into development and operations workflows from the start.

Answer-42: Risks include outdated libraries, vulnerabilities, and lack of proper maintenance.

Answer-43: They automate security tasks, provide better integration, and scale with cloud environments.

Answer-44: Implement strong authentication, validate inputs, encrypt traffic, and monitor API usage.

Answer-45: By monitoring user activities, implementing role-based access, and enforcing least privilege.

Answer-46: It identifies security weaknesses early to enable quick remediation.

Answer-47: DLP prevents sensitive data leaks by monitoring and controlling data flows.

Answer-48: Legacy apps might lack modern security features and require re-architecting for cloud security.

Answer-49: It detects vulnerabilities and malware before deployment to production.

Answer-50: Limit permissions, validate inputs, encrypt environment variables, and monitor function execution.
