Security for Cloud
High-level security concerns like unauthorized data exposure and leaks, weak access controls, susceptibility to attacks, and availability disruptions affect traditional IT and cloud systems alike. Like any computing environment, cloud security involves maintaining adequate preventative protections.
What is Cloud Computing Security?
Cloud computing security refers to the technical discipline and processes that IT organizations use to secure their cloud-based infrastructure. Through a cloud service provider, IT organizations can outsource the management of every aspect of the technology stack, including networking, servers, storage, virtualization, operating systems, middleware, runtime, data, and applications. Cloud computing security includes the measures that IT organizations take to secure all of these components against cyber attacks, data theft, and other threats.
What makes cloud security different?
Traditional IT security has felt an immense evolution due to the shift to cloud-based computing. While cloud models allow for more convenience, always-on connectivity requires new considerations to keep them secure. Cloud security, as a modernized cybersecurity solution, stands out from legacy IT models in a few ways.
Cloud security differs based on the category of cloud computing being used. 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.
