Cloud security involves the procedures and technology that secure cloud computing environments against both external and insider cybersecurity threats. Cloud computing, which is the delivery of information technology services over the internet, has become a must for businesses and governments seeking to accelerate innovation and collaboration. Cloud security and security management best practices designed to prevent unauthorized access are required to keep data and applications in the cloud secure from current and emerging cybersecurity threats.

Cloud computing categoriesCloud security differs based on the category of cloud computing being used. There are four main categories of cloud computing:
When using a cloud computing service provided by a public cloud provider, data and applications are hosted with a third party, which marks a fundamental difference between cloud computing and traditional IT, where most data was held within a self-controlled network. Understanding your security responsibility is the first step to building a cloud security strategy.

Their business model hinges on preventing breaches and maintaining public and customer trust. Cloud providers can attempt to avoid cloud security issues with the service they provide, but can’t control how customers use the service, what data they add to it, and who has access. Customers can weaken cybersecurity in cloud with their configuration, sensitive data, and access policies. In each public cloud service type, the cloud provider and cloud customer share different levels of responsibility for security. By service type, these are:
Within all types of public cloud services, customers are responsible for securing their data and controlling who can access that data. Data security in cloud computing is fundamental to successfully adopting and gaining the benefits of the cloud. Organizations considering popular SaaS offerings like Microsoft Office 365 or Salesforce need to plan for how they will fulfill their shared responsibility to protect data in the cloud. Those considering IaaS offerings like Amazon Web Services (AWS) or Microsoft Azure need a more comprehensive plan that starts with data, but also covers cloud app security, operating systems, and virtual network traffic—each of which can also introduce potential for data security issues. Cloud security challengesSince data in the public cloud is being stored by a third party and accessed over the internet, several challenges arise in the ability to maintain a secure cloud. These are:
Cloud security solutionsOrganizations seeking cloud security solutions should consider the following criteria to solve the primary cloud security challenges of visibility and control over cloud data.
Which of the following should you consider before using a cloud service for work?SecurityOf course, security is always an aspect to consider when talking about cloud computing. Service providers promise that they can be more secure than physical data centers. Protection of expertise and assets is a key requirement. Cloud applications need to protect data being transferred over the net.
