Abstract
With the rapid development of information technology, cloud computing, as a new computing mode and service mode, has penetrated into all walks of life and become a key force to promote digital transformation. With its efficient, flexible and scalable characteristics, cloud computing provides convenient computing resources and services for enterprises and individuals. However, with the widespread popularization of cloud computing applications, its security problems are becoming increasingly prominent. Frequent security incidents such as data leakage, identity theft and malicious attacks pose serious threats to users' privacy and the security of enterprise assets. Therefore, how to effectively address the security challenges in the cloud computing environment and ensure the security and integrity of user data has become an urgent problem to be solved. This paper deeply discusses the security problems of cloud computing technology in practical application, including data leakage and loss, identity theft and fraud, insecure interface and API, malicious attack and denial of service, etc. In view of these problems, this paper puts forward corresponding protection countermeasures, including strengthening data protection and backup, strengthening authentication and access control, optimizing security interface and API management, and developing strategies to defend against malicious attacks and service interruption. Through theoretical analysis and practical verification, this paper provides a systematic and scientific solution for the security protection in the cloud computing environment, which helps to improve the security and reliability of cloud computing technology, and promote the wide application and development of cloud computing technology.
