云计算的主要威胁(云计算中的数据安全主要包括)

The main risks of supply chain cloud computing include the following aspects:
1. Data security risk: Since cloud computing is based on the public Internet for data transmission and storage, data security The question is a critical one. Enterprises need to take appropriate security measures to ensure that sensitive data is not accessed or tampered with by unauthorized personnel, and to avoid security issues such as hacker attacks and virus infections.
2. Supplier stability risk: Enterprises must pay attention to their stability and credibility when choosing cloud computing suppliers. If the supplier encounters technical failures, service interruptions, bankruptcy and other problems, it will have an impact on the company's operations.
3. System reliability risk: The cloud computing platform needs to ensure stable system operation and maintain good response speed and technical performance during peak periods. If the system is unreliable and has frequent failures, it will affect the operational efficiency of the enterprise.
4. Risk of increased costs: Using a cloud computing platform requires paying certain fees, including usage fees, maintenance fees, etc. Enterprises must conduct a cost-benefit analysis to ensure that cloud computing can bring substantial benefits to the enterprise.
5. Legal compliance risks: The use of cloud computing platforms must comply with relevant laws and regulations to avoid legal issues such as infringement of intellectual property rights and data security. Businesses must ensure that they comply with relevant legal requirements when using cloud computing platforms.
The above points are the main risks of supply chain cloud computing. Enterprises need to pay attention to and take corresponding measures to reduce risks when using cloud computing platforms.

The existing problems of cloud computing applications mainly include the following points:
1. Virtualization security issues: If the physical host is damaged , the virtual server it manages may be compromised due to communication with the physical host. If the physical host and the virtual machine do not communicate, the virtual machine may escape. If the virtual network on the physical host is compromised, the virtual machine will also be compromised due to the communication between the physical host and the virtual machine, and the scenario where one virtual machine monitors another virtual machine.
2. Security issues in data sets: User data storage, processing, network transmission, etc. are all related to cloud computing systems, including how to effectively store data to avoid data loss or damage, and how to apply multi-tenant applications Perform data isolation, how to avoid data services being blocked, etc.
3. Cloud platform availability issues: Users’ data and business applications are in a problem system where the cloud platform is attacked, and its business processes will depend on cloud platform service continuity, SLA and IT processes, and security policies. , event processing and analysis, etc. pose challenges. In addition, when a system failure occurs, how to ensure the rapid recovery of user data has also become an important issue.
4. The problem of attacks on cloud platforms: Due to the high concentration of users and information resources, cloud computing platforms are easy to become targets of hacker attacks. The consequences and destructiveness caused by this denial of service will be obvious. Exceeding the traditional enterprise network application environment.
5. Legal risks: Cloud computing has weak application areas and high information mobility. Information services or user data may be distributed in different regions or even different countries. There are legal differences and differences in government information security supervision and other aspects. Disputes; at the same time, the judicial evidence collection problems that may be caused by the blurring of physical boundaries between users caused by technologies such as virtualization cannot be ignored.

A big problem facing cloud computing is security.
The development of cloud computing allows data and information to be stored in remote data centers instead of local devices, which brings many new security challenges. First, data security and privacy protection have become an important issue. Cloud computing service providers must ensure that data stored in the cloud is not accessed or misused by unauthorized third parties. In addition, since data is transmitted in the cloud, security during data transmission also needs to be guaranteed to prevent data from being intercepted or tampered with.
Secondly, the multi-tenant feature in the cloud computing environment also brings new security issues. Different users share the same set of infrastructure and resources. Without effective isolation measures, data leaks or attacks may occur. Therefore, cloud computing service providers need to take effective measures to isolate different tenants and ensure their data security.
Furthermore, virtualization technology is one of the core technologies of cloud computing, but the virtualization environment may also cause new security issues. Virtualization software may have vulnerabilities that may be exploited maliciously, posing a threat to the security of the virtualization environment.
In summary, security issues are an important issue faced by cloud computing, and effective measures need to be taken to ensure the security of the cloud computing environment. For example, strengthen data encryption and transmission security, implement strict access control policies, conduct regular security audits and vulnerability patching, etc.
