A secure cloud migration is crucial to minimize risks of breaches, loss of operations, and data leaks. A security-first approach involves ongoing monitoring and management of threats through automated policies, processes, and controls. This requires a combination of modern tools, techniques, and processes, including Cloud Security Posture Management (CSPM), Endpoint Detection and Response, key management and secrets management, policy-as-code, Logging and Security Information and Event Management (SIEM), security assurance and compliance, and penetration testing. By implementing these elements, organizations can build a solid security structure for their cloud deployment, improve their overall business agility, and protect their valuable assets from cyber attacks.
