Although many companies are fully aware of the benefits of cloud services, many have slowed down or even halted their implementation due to poor planning and insufficient analysis of the security problems associated with the cloud. On the other hand, cloud providers often cannot clearly determine the level of protection offered, so potential customers do not know who should implement basic security measures. This is why this white paper identifies security measures that must be considered before deploying cloud services.
Security allows you to control the risks associated with this technology, while using its advantages. Here, cloud security also describes the steps necessary to logically and securely promote your adoption of cloud services.
The path to secure cloud adoption. Define your business strategy The cloud delivers business continuity with lower design and deployment costs, and provides many business benefits. However, not only offering a one-stop solution, but also developing tips for the safe deployment of clouds.
Business criticality: Think about intellectual capital, formulas, patents, plans, industry secrets, and other important information for your business. Confidential information: among them personal or financial data (bank account number, card number, etc.). also new risks, in addition to those that it has in common with traditional IT systems.
Before considering the cloud, it is important to understand your business strategy and your expectations for this technology. How do you plan to integrate it with other IT services? What will be the added value for your business? Also evaluate the value and criticality level of the data, services and applications that you plan to host in the cloud. And most importantly, determine your acceptable level of risk for these resources. Obviously, before developing a strategy, companies must carefully consider the business reasons that motivate them to move to the cloud.
Creating a global roadmap requires, first of all, a good understanding of these reasons. In order to intelligently choose which services to deploy in the cloud, IT departments must maintain and align with the strategic vision and goals of the enterprise. This step will also allow you to start defining the basic security measures expected from your cloud service provider (CSP) and any additional controls necessary to meet your business requirements. 2. Select the resources to migrate to the cloud. Knowing and understanding what IT resources your company plans to transfer to the cloud, you can determine the impact of inaccessibility, loss, theft and leakage of these resources. resources at your bid. This step is therefore crucial. Companies must evaluate information or a process to determine its value and importance. They can then protect it with appropriate security measures. Organizations need to understand the business criticality of the processes and applications that they plan to migrate to the cloud. In other words, they need to find out how problems accessing these processes and applications will hurt deals. It is also important to consider the interdependencies between business processes.
Cloud service and deployment models. Given the diversity of cloud service and deployment models, organizations must carefully consider the advantages and disadvantages of each. Then they will be able to outline a plan for their adoption of cloud services.
Cloud Services Models. There are three models here, each of which requires a different level of participation from the CSP: – Infrastructure as a Service (IaaS) IaaS provides a complete IT infrastructure as a service. Users are paid based on the computing power consumed over time. The service includes applications, equipment, storage, etc.
Relatively simple and economical to set up, this model can be extended to all your computing resources, depending on the needs of your business. Platforms as a Service (PaaS) PaaS provides the infrastructure and platforms on which cloud users deploy their own applications. This allows organizations to develop applications using the resources of an external cloud provider. Key: reducing application development costs and their easier allocation for specific projects. Software as a Service (SaaS) SaaS consists of deploying an application through an external application service provider. As a result, organizations may include the purchase of these applications for their operating costs, rather than their capital costs for equipment, OS licenses and applications, and other storage systems and data centers.
