Cloud Security Architecture Guide

Ultimate Guide to Cloud Security Architecture

A cloud security architecture combines platform security layers, structures, tools, Software, instructions, and best practices available in the security solution. Cloud security generally means protecting applications, data, and infrastructure from breaches. It applies to all cloud environments like public cloud, private cloud, and hybrid cloud. In this article, we will explore cloud security architecture. 

Key elements of a cloud security architecture

The following are the key elements that one should consider while deploying cloud security architecture: 

  • Entry Level Security 
  • Centralized management of components  
  • Alerts & Notifications  
  • Centralization, Standardization & Automation 
  • Redundant & resilient design 
  • Dedicated storage for deployments   
  • Resiliency & scalability  

Cloud Security Architectures - Shared Responsibility

The service model of an organization decides which type of cloud security architecture should be appropriate for that organization. The different types of service models include IaaS (Infrastructure as a Service), SaaS (Software as a Service), and PaaS (Platform as a Service). Let’s find out the responsibilities of these service types in detail: 

IaaS Shared Responsibility

In this service model, the business purchases infrastructure from the cloud provider and then install it in their applications, middleware, and system. Microsoft Azure is the perfect example of an IaaS. It is usually responsible for the security of all the infrastructures of the organization. 

SaaS Shared responsibility

In this service model, the company purchases cloud-based applications from a provider. Office 365 and Salesforce are the best examples of this service model. It is specifically responsible for the security of elements associated with the Software like customer network security, identity management, etc. 

PaaS Shared Responsibility

In this service model, the company purchases a cloud platform from a cloud provider. They use the platform to develop, run and manage different applications without developing or managing. Amazon Web Services is the right example for this type of service model. It is responsible for application configuration, deployment, and permissions security. 

Next steps 

While developing a cloud security architecture, you should understand the shared responsibilities of different service models for designing the best approaches per your organization’s needs. For this, you can consider working with a skilled cloud security vendor compared to trying to build it on your own.
