5. Cloud Application Security: Ensures the security of cloud-based applications and their underlying code.
6. Cloud Information Security and Data Management: Manages the security of information assets stored in the cloud.
7. Cloud Identity and Access Management: Controls access to cloud resources and ensures the authentication and authorization of users.
8. Cloud Security Incident Management: Provides guidance on incident response and recovery procedures.
9. Cloud Supply Chain Security: Manages security risks associated with third-party cloud services and vendors.
10. Cloud Security Assessment and Monitoring: Continuously monitors cloud infrastructure and applications for security vulnerabilities and threats.
11. Cloud Security Training and Awareness: Educates and trains employees on cloud security best practices.
12. Cloud Security Automation: Automates security tasks to improve efficiency and effectiveness.
13. Cloud Data Loss Prevention: Protects data from accidental or malicious deletion or unauthorized access.
14. Cloud Privacy: Ensures compliance with privacy regulations and protects personal data in the cloud.
