Empower Your Cloud Security

Architecting Strong Defenses for Your Digital Horizon

What is cloud security architecture?

Cloud security architecture is the umbrella term used to describe all hardware, software and infrastructure that protects the cloud environment and its components, such as data, workloads, containers, virtual machines and APIs.

The cloud security architecture provides documentation for how the organization will:

Define security principles, rules, procedures and governance for all cloud services and applications from development through runtime

Properly configure activities and operations within the cloud to maintain optimal security

Define identity and access management (IAM) rights for all cloud users

Secure data, applications and other assets

Connect cloud security practices, tools and technologies with the broader enterprise architecture and enterprise security strategy

The cloud security architecture is a core component of every cloud security strategy, which protects everything within a cloud environment, including the cloud infrastructure, cloud data, and cloud applications.

Why is cloud security architecture important?

When migrating to the cloud, security can be an afterthought for many organizations. This leaves the organization open to risks and threats specific to the cloud environment that are not protected by traditional on-premise security measures and tools.

While many organizations have deployed a series of point solutions to improve security in the cloud, this patchwork approach can significantly limit visibility, which makes it difficult to achieve a strong security posture.

Organizations that have migrated to the cloud or are in the process of doing so must develop a comprehensive security strategy custom built for the cloud that integrates with the overarching enterprise security strategy and solutions.

4 key elements of cloud security architecture

The cloud security architecture consists of all hardware, software and infrastructure to maintain security in the cloud environment. Four key elements of the cloud security architecture are:

1. Cloud security posture management (CSPM): Focuses on security of cloud APIs, preventing misconfigurations and integrations into the CI/CD pipeline.

2. Cloud Workload Protection Platform (CWPP): Oversees runtime protection and continuous vulnerability management of cloud containers.

3. Cloud Access Security Broker (CASB): Works to improve visibility across endpoints that includes who is accessing data and how it is being used.

4. Cloud application security: Application-level policies, tools, technologies, and rules to maintain visibility into all cloud computing activity and protect cloud-based applications throughout the development lifecycle.

Cloud security architecture and the shared responsibility model

According to the Shared Responsibility Model, security and compliance is a shared responsibility between the customer and the cloud provider. The cloud service providers (CSP)—such as Amazon AWS, Microsoft Azure, and Google GCP—must monitor and respond to security threats related to the cloud’s underlying infrastructure. Meanwhile, the end users, including individuals and companies, are responsible for protecting the data and other assets they store in a public, hybrid, and multi-cloud environment.

Unfortunately, this point can be misunderstood, leading to the assumption that cloud workloads are fully protected by the cloud provider. This results in users unknowingly running workloads in a public cloud that are not fully protected, meaning adversaries can target the operating system and the applications to obtain access. Even securely configured workloads can become a target at runtime, as they are vulnerable to zero-day exploits.

For organizations that use a cloud-based model or are transitioning to the cloud, it is important to develop and deploy a comprehensive security strategy that is specifically designed to protect and defend cloud-based assets.

Cloud security architectures by service models

There are three main cloud service models, all of which are subject to the shared responsibility model.

> Software as a service (SaaS): SaaS is a software delivery model wherein the vendor centrally hosts an application in the cloud that can be used by a subscriber.

> Platform as a service (PaaS): PaaS is a platform delivery model that can be purchased and used to develop, run and manage applications. In the cloud platform model, the vendor provides both the hardware and software generally used by application developers; the service provider is also responsible for security of the platform and its infrastructure.

> Infrastructure as a service (IaaS): IaaS is an infrastructure delivery model wherein a vendor provides a wide range of compute resources such as virtualized servers, storage and network equipment over the internet. In this model, the business is responsible for maintaining security of anything they own or install on the infrastructure, such as the operating systems, applications, and middleware.

3 security principles for a cloud architecture

Maintaining a secure cloud architecture is based on three security principles: accessibility, integrity and availability.

1. Accessibility: Ensuring cloud-based services, data and other assets are accessible only to authorized, authenticated users and devices

2. Integrity: Ensuring the system and applications function consistently and efficiently

3. Availability: Ensuring the system is available to users, including employees and customers, and protected from service-related attacks, such as Denial of Service (DoS) or Distributed Denial of Service (DDoS) attacks

Unraveling Complexities and Providing Clarity on Cloud Security Architecture

How is security maintained in cloud architecture?

Encryption is a different kind of cloud computing security. Your data should be encrypted both in transit and at rest. Another sort of security in cloud computing involves recurring security assessments and the fixing of any flaws.

How can you design security architecture in cloud explain?

Protection at Every Layer. Components are managed centrally. Design with Redundancy & Resilience. Scalability and Elasticity. Storage that is suitable for deployments. Notifications & Alerts. Automation, Standardization, and Centralization

What are cloud security models?

Depending on the kind of cloud service?IaaS (Infrastructure as a Service), PaaS (Platform as a Service), or SaaS?the cloud security architecture paradigm varies (Software as a Service). Below, we discuss several security factors for each device.

What is security architecture?

Security architecture is a comprehensive security design that takes into account both the requirements and the hazards present in a certain situation or environment. Additionally, it details where and when to implement security controls. In general, the design process is repeatable.

What is cloud security principles?

the rules for cloud security. the protection of data while it is in transit. Principle 2: Resilience and asset protection. Principle 3: Keep consumers apart. Principle 4: Framework for governance

What is the architecture of cloud computing?

The way technological elements come together to create a cloud, where resources are pooled through virtualization technology and shared over a network, is known as cloud architecture. The elements of a cloud architecture are as follows: an entrance platform (the client or device used to access the cloud)

What are the types of security architecture?

Five basic groups of security services are taken into account by the Security Architecture of the OSI Reference Model (ISO 7498-2): authentication, access control, confidentiality, integrity, and non-repudiation.
