Cloud computing is incredibly powerful, while their motivations vary, businesses of all sizes, industries, and geographies are turning to cloud services. The cloud should be embraced but it does come with risks that require securing and constant monitoring.
Cloud security is of the utmost importance to ensure that your information isn’t getting into the wrong hands. This is especially true if the data stored needs to meet compliance levels.
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.
There are four main categories of cloud computing:
- Public cloud services, operated by a public cloud provider — These include software-as-a-service (SaaS), infrastructure-as-a-service (IaaS), and platform-as-a-service (PaaS).
- Private cloud services, operated by a public cloud provider — These services provide a computing environment dedicated to one customer, operated by a third party.
- Private cloud services, operated by internal staff — These services are an evolution of the traditional data center, where internal staff operates a virtual environment they control.
- Hybrid cloud services — Private and public cloud computing configurations can be combined, hosting workloads and data based on optimizing factors such as cost, security, operations, and access. The operation will involve internal staff, and optionally the public cloud provider.
Most cloud providers attempt to create a secure cloud for customers. Their business model hinges on preventing breaches and maintaining public and customer trust. Customers can weaken cybersecurity in the cloud with their configuration, sensitive data, and access policies.
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. Organisations 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.
