Shared Security Model

Introduction to the Shared Security Model

The Shared Security Modelg is a fundamental framework in cloud computing that delineates which security tasks fall to the provider and which remain with the customer. As cloud adoption accelerates—Gartner reported that 85% of enterprises will adopt a shared responsibility framework by 2024—clarity in security ownership becomes critical. Provider take charge of the underlying infrastructure, while customers focus on protecting their data, applications, and configurations within the cloud environment.

Core Principles of the Shared Security Model

At its heart, the Shared Security Model is split into two domains:

• Security of the cloud: The provider’s obligation to secure physical data centers, network architecture, servers, and virtualization layers.
• Security in the cloud: The customer’s responsibility to manage operating systems, applications, data, identity and access controls, and configuration settings.

To illustrate this separation:

Security Layer	Provider Responsibility	Customer Responsibility
Infrastructure	Physical data centers, hardware, network security	N/A
Virtualization	Hypervisor protection	N/A
Operating System	N/A	Patching and OS hardening
Applications	N/A	Secure configuration and updates
Data	N/A	Encryption, access management

Common Implementation in Cloud Service Models

Different service offerings shift the lines of responsibility:

• IaaS (e.g., AWS EC2): Providers secure hardware and virtualization; customers manage operating systems, applications, and data.
• PaaS (e.g., Google App Engine): Providers add runtime and middleware security; customers focus on their code and data.
• SaaS (e.g., GeeLark): Providers handle nearly all layers; customers concentrate on user access, data integrity, and compliance.

Security Challenges in Multi-Account Management

Managing multiple identities and sessions introduces risks such as cross-contamination of browser fingerprints, shared cookies, and credential exposure through phishing or keylogging. Traditional browsers struggle to maintain true isolation, making dedicated environments like GeeLark’s cloud phone platform essential for professional account managers.

GeeLark’s Implementation of the Shared Security Model

GeeLark covers all “security of the cloud” responsibilities:

• Hardware security—enterprise-grade servers in secured, audited data centers (SOC 2 Type II)
• Device virtualization—unique Android instances with genuine device fingerprints
• Network protection—end-to-end encryption and per-device proxy integration
• Isolation mechanisms—hardware-enforced separation between user environments

Each GeeLark device mimics a physical phone with its own IMEI, serial number, Android OS, and network stack. This approach avoids the detection risks common to browser-based antidetect solutions like Multilogin.

Customer Responsibilities When Using GeeLark

Customers manage “security in the cloud” by:

1. Credential security—using strong, unique passwords and enabling 2FA where offered
2. App management—keeping Android applications updated and securely configured
3. Access controls—defining user permissions for team collaboration
4. Data protection—encrypting sensitive files and regularly auditing access logs

Benefits of the Shared Security Model with GeeLark

1. Enhanced isolation—each account runs in a distinct Android environment
2. Reduced detection risk—hardware-backed device fingerprints resist emulator checks
3. Streamlined management—centralized control over multiple secure identities
4. Time efficiency—automated logins without sacrificing security

Conclusion

The Shared Security Model offers a clear division of security duties between providers and users. Through its unique cloud phone architecture, GeeLark secures infrastructure at the hardware level while empowering customers to protect their applications and data. Combining isolated Android environments with robust credential practices delivers end-to-end protection for professionals managing multiple accounts.

People Also Ask

What is a shared security model?

The shared security model is a framework in cloud computing that divides security responsibilities between the provider and the customer. The provider secures the underlying infrastructure—data centers, hardware, network and virtualization (“security of the cloud”). The customer secures their operating systems, applications, data, identity and access management, and configurations (“security in the cloud”). This clear separation of duties minimizes gaps and ensures robust protection across the entire cloud environment.

What is the shared security responsibility model of AWS?

In AWS’s shared security responsibility model, Amazon secures the “cloud” while you secure what’s “in the cloud.” AWS handles physical data centers, hardware, networking, hypervisors, and foundational services. You’re responsible for configuring and managing your operating systems, applications, data, network settings (such as security groups and ACLs), identity and access management, encryption, and patching. By clearly dividing duties—AWS providing infrastructure security and you controlling your workloads and configurations—you ensure comprehensive protection across your AWS environment.

What are the 4 cloud service models?

The four primary cloud service models are:

1. Infrastructure as a Service (IaaS): Virtualized compute, storage and networking resources you manage.
2. Platform as a Service (PaaS): Managed runtime and development tools for building and deploying apps.
3. Software as a Service (SaaS): Fully hosted applications accessed over the internet.
4. Functions as a Service (FaaS) or Serverless: Event-driven compute where individual functions run on demand without managing servers.
