How to securely migrate and maintain cloud services

In more and more cases, CIOs (Chief Information Officer) and CSO (Chief Security Officer) are assigned the tasks for migrating their core businesses to the cloud, at least these problems are headaches and challenges for security practitioners. It is a challenge to quickly form a set of security specifications that can be followed. Another problem arises: although most enterprises are already using network security specifications, these specifications are developed by traditional third-party security vendors for traditional security, there are often some that are not really suitable for cloud services. However, cloud maintenance is different from traditional third-party solutions. For example, the seller is responsible for cloud security control. Generally, security experts only need to manage and maintain key security control. For example, an enterprise, as a PaaS (platform as a service) cloud service provider, is generally responsible for the security of applications. PaaS cloud service providers will be responsible for supporting applications of fixed platforms and infrastructure. It is essential to clearly outline who is responsible for which component requirements to provide the required security levels and be flexible enough to adapt to these different service models. First, you need to establish a framework: To build cloud security, you need to create a rule to review, approve, and manage cloud service providers. Here is an example of an enterprise: to develop such a framework, we need to collect business, technical, and security requirements with relevant personnel. Then it analyzes the detailed issues related to the data storage and processing by the cloud service provider. After you fully understand this, you can use existing enterprise security policies and standards to add additional content to match the cloud computing environment. The premise requires that the policies should be flexible enough to cope with emergencies. Once the policies are fully compliant with the Cloud Security Framework, you need to discuss how to effectively implement them at an enterprise meeting. The importance of the Framework should be communicated during the meeting, it also discusses how enterprises can adjust existing security policies to the cloud framework. Once the framework is adopted by enterprises, not only the IT department, but all business departments of the enterprise can use the business, and eventually all the business platforms of the enterprise are migrated to the cloud, this framework can unify the operational specifications of all employees to ensure the security and stability of enterprise data in the cloud. Security Management of cloud services: in addition to the application cloud security framework, enterprise IT personnel should also immediately review the security of cloud service providers and test whether the services of cloud computing providers are reliable, if there is a similar service interruption or employee usage problem, it can be solved in a timely manner. Security engineers also need to track problems in their work in a timely manner. Although enterprises use cloud services to store and process large volumes of file data, cloud services are always unstable, it is essential to synchronize data to the local machine in a timely manner and manage the data. The best solution to this problem is to work with cloud service providers to develop a program for review, approval, and management. This solution requires the cloud service provider to allow our enterprise's security personnel to have in-depth access to the technical processes of the cloud service provider, so as to modify the cloud security framework for the provider's business. In the process of using cloud services, employees can collect comments and questions about the service, or collect opinions through the form of a questionnaire, and coordinate and communicate with cloud service providers through the summarized information, on the one hand, it can solve the needs of enterprises, and on the other hand, it can improve the user experience of the cloud service provider products. During use, employees are collected in a timely manner on the cloud security framework, and service operation vulnerabilities are handled to avoid leakage of sensitive enterprise data. By leveraging your knowledge and existing technologies, as a security professional, you can quickly respond to any business needs, at the same time, the risks from core applications to the cloud environment are minimized. This solution not only enables us to review the Stability of cloud providers in a timely manner, but also provides an application to manage our own cloud services, so that our enterprise's data can still be protected locally on the cloud.
