Cloud Security is the shared responsibility between cloud service providers (CSPs) and their customers to secure data, applications, and infrastructure within the cloud. The Shared Responsibility Model outlines the responsibilities of each party, based on the type of cloud service: software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS).

Protecting Data In the Cloud

Data in the cloud should be protected by encryption at rest and in transit to prevent attackers from reading or intercepting it. Encryption is the most basic step, but it should be complemented with other data protection tools such as multifactor authentication (MFA), microsegmentation, vulnerability assessment, and security monitoring.

Compliance and Legal Issues

Cloud computing is a great option for organizations that need to store large amounts of data or comply with regulations. For example, the European Union’s GDPR imposes new data privacy laws on companies that store personal information.

Multitenancy and Data Isolation

As data is moved to the cloud, it’s important to segment and isolate resources, such as instances, containers, applications, and full systems. By separating the data from other tenants and ensuring that data is isolated, organizations can better secure their cloud environment while still maintaining flexibility to access their data as needed.

Identity and Access Management

Managing cloud access is challenging due to the different types of cloud environments, the use of default and embedded credentials, and the complexity of cloud service provider (CSP) policies. Organizations can benefit from a comprehensive Cloud Identity and Access Management (CIAM) solution that provides visibility and control across a wide range of cloud environments, including on-premise, public, and private cloud.
