Restrict data access to necessary individuals or devices to reduce security risks.
- Third-Party Services
Verify encryption practices of cloud services before sharing sensitive data with clients or collaborators.
- Provider Security
Evaluate cloud providers based on security audits, data encryption policies, and access management practices.
Understanding Zero Trust Security
Zero Trust, coined in 2010, challenges the idea of trusting any network entity by default.
It requires verifying every access attempt checking, authorizing, and securing regardless of location.
This approach promotes minimal user privileges, strict security for web applications, and uses micro-segmentation to create secure zones in data centers and clouds, ensuring robust traffic control between them.
Types of Cloud Security
Cloud security solutions encompass various types to address evolving threats:

Data Loss Prevention (DLP) |
Safeguards sensitive data in the cloud through encryption and monitoring, preventing unauthorized access. |
These solutions are crucial for maintaining security and resilience in cloud-based systems, protecting against data breaches and enabling quick recovery from disruptions.
How Does Cloud Security Work?
Cloud security works by combining policies, processes, and technologies to protect data, ensure compliance, and manage privacy, access, and authentication for users and devices.
Cloud service providers (CSPs) use a shared responsibility model where both they and their customers have security duties. The CSP secures core infrastructure like servers and networks, while customers secure what operates “in” the cloud, such as applications and data.
Responsibilities vary based on the service model:
Infrastructure as a service (IaaS)
Customers secure data, applications, and user access; CSPs secure servers, storage, and network.
Platform as a service (PaaS)
Customers secure data and applications; CSPs secure servers, storage, network, and operating system.
Software as a service (SaaS)
Customers secure data and user access; CSPs secure servers, storage, network, operating system, and applications.
A new approach, shared fate, is emerging where CSPs provide more guidance and tools for secure cloud use, moving beyond traditional shared responsibility models.
