Several security risks of cloud computing services

The resolution of security issues is a key factor to determine whether cloud services can be recognized by users. Cloud security is also one of the main obstacles to the current cloud computing applications. In addition to system faults that may cause large-scale computing resources, cloud computing security risks also include the lack of unified security standards, applicable regulations, and user privacy protection, data sovereignty, migration, transmission, security, disaster recovery, and other issues.

Cloud security can be divided into two categories in nature: user data privacy protection, and security for traditional internet and hardware devices.

In terms of data privacy protection, when user information is stored in your computer, anyone who needs this information must be allowed. hacker intrusion triggers the law. However, when user information is stored on the cloud, there is no clear law that cloud service providers or other official organizations cannot view this information. What kind of punishment will these privacy leaks be incurred.

 

 

Is graph cloud secure?

With the gradual improvement of IT Laws and Regulations, cloud computing users can treat cloud service providers as banks to cooperate with each other with confidence. They dare to save money in banks and store data in cloud service providers.

In terms of technical security, multi-tenant security issues are the first.Different users are isolated from each other to avoid mutual influence. In the cloud era, some technologies need to be used to prevent users from intentionally or unconsciously "connecting to the door ".

Second, the use of third-party platforms brings security risks.Not all vendors that provide cloud services have their own data centers. Once a third-party cloud platform is rented, the administrator privilege of the service provider exists.

Third, service continuity issues.Traditional Internet services also have single point of failure (spof). Therefore, dual-Machine backup is required: The master server stops service, and the slave server starts and provides normal services in a short time.

In the traditional mode, a group of services stop only affects their own businesses and users. However, in the cloud environment, the services of cloud service providers are terminated, and the services of cloud service providers are not affected by one user, it is a large user, and the scope may be very large.

Cloud security technology can consider how to improve applications in the following dimensions.

First, data security:In the cloud environment, user data is directly computed and stored on the cloud. The ownership of data is separated from the management right, leading to data security issues in the cloud environment. Currently, cloud data security protection technologies include enhanced encryption technology, key management, data isolation, and data residue.

Second, virtualization security:Virtualization Technology enhances the scalability of infrastructure, software platforms, and business systems, and gradually lacks traditional physical security boundaries, in the past, the security domain/security boundary-based protection mechanism was difficult to meet the multi-tenant application mode in a virtualized environment. users' information security, data isolation, and other issues become more urgent in the shared physical resource environment.

Due to the introduction of virtualization technology, the cloud environment involves two problems: virtualization software security and virtual server security. The security problem brought about by virtualization is only just getting started. The security mechanism in the virtual environment is still quite different from the security measures in the traditional physical environment. Therefore, users who want to migrate to a cloud computing environment need to have a detailed understanding of the security responsibilities of users and cloud service providers. A secure cloud computing environment needs to be jointly maintained by users and cloud service providers.

Third, terminal security:With the development of cloud computing, cloud terminals have emerged. Currently, terminal security protection can be implemented in four aspects: terminal security infrastructure, terminal hardware chip trusted technology, operating system security mechanism, and terminal application security update mechanism.

Fourth, application security:The flexibility, openness, and public availability of the cloud environment pose a great challenge to application security. When deploying applications, cloud service providers should fully consider possible security risks. Users who use cloud services should be aware of security and take necessary measures to ensure the security of cloud terminals. For example, you can use encryption technology to ensure the confidentiality of applications that process sensitive data and servers. Cloud users should establish a regular update mechanism to promptly patch or update applications using cloud services.

Summary: The Development of China's cloud computing industry must carry out in-depth research on data migration, backup, encryption, and location control to ensure the ease of use, availability, stability, and security of cloud services. Security issues include constantly improving cloud computing laws and regulations to enhance users' confidence in using cloud computing. In addition to technical issues, user self-protection awareness must also be strengthened. Although there are various security measures to protect the data, and even more comprehensive laws and regulations will be introduced in the future, the final data security remains largely in the hands of users.
