Ultimately, while both environments rely on a shared responsibility model, managed services usually offer more integrated security features, whereas self-managed environments require more proactive security management and expertise from the organizations themselves.

Shared Responsibilities in Cloud Security

What are the responsibilities of cloud providers and customers in cloud security?

The responsibilities in cloud security are clearly delineated by the Shared Responsibility Model, which emphasizes the collaborative nature of security management between cloud service providers (CSPs) and their customers.

For cloud providers, they are tasked primarily with securing the underlying infrastructure. This includes the physical data centers, network, and cloud service operation itself, ensuring that maintained services are both available and secure. Providers implement various security measures such as data encryption, firewalls, and identity management to protect their infrastructure.

Conversely, customers must focus on securing their applications and data. This includes managing user access, implementing strong authentication protocols, and protecting data both during transmission and when stored (data at rest). The specific responsibilities can shift depending on the cloud service model being utilized:

• SaaS (Software as a Service): The provider is generally responsible for most security obligations.
• PaaS (Platform as a Service): Shared responsibilities, with the provider managing the underlying hardware and operating system, while customers handle their applications.
• IaaS (Infrastructure as a Service): Customers carry a significant portion of the security load since they manage their own systems hosted on the provider's infrastructure.

Notably, a high percentage of cloud security failures can be traced back to customer mismanagement, underscoring the importance of adhering to the shared responsibilities outlined in this model.

Challenges and Best Practices in Cloud Security for IT
