What type of security model do public clouds implement?

1. Private

2. Hybrid

3. Shared

4. Community

The correct answer is: Shared

Public clouds implement a shared security model, which means that the cloud provider and the customers share responsibilities for securing the data and applications in the cloud environment. In this model, the cloud provider is responsible for securing the infrastructure, including hardware, software, networking, and facilities. Meanwhile, the customers are responsible for securing their data, identities, applications, and operating systems. This shared security model is vital because it allows organizations to take advantage of the scalability and flexibility of public cloud services while maintaining a clear understanding of their security responsibilities. The division of responsibilities can often lead to a misconception about who is accountable for certain aspects of security, highlighting the need for organizations to understand and manage their own security requirements in conjunction with the cloud provider's protections. The other described models—private, hybrid, and community—do not align with the public cloud environment as they involve varying levels of resources and management concerns typically focused on individual organizations or specific groups rather than the open shared resources of a public cloud.
