Unpacking the Shared Responsibility Model
In SaaS environments, the shared responsibility model is based on a crucial set of guidelines that both service providers and users must follow.
Let’s explore how the model works.
- Infrastructure and Uptime:
SaaS providers are responsible for maintaining the infrastructure’s backbone, encompassing hardware, networking, and seamless service uptime.
- Physical Security:
The guardianship of physical data centers and enforcing security measures fall under their purview, including access controls, surveillance, and disaster recovery protocols.
- Platform Security:
Providers stand as sentinels of platform security, tasked with fortifying application layers, managing patches, and conducting vulnerability evaluations.
- Content and Data Management:
From its inception to modification and potential removal, the users govern user access, permissions, and content administration.
- Configuration and Settings:
The onus of configuring the application’s security parameters rests with users, covering multi-factor authentication, robust passwords, and settings.
Confirming compliance while respecting industry-specific regulations becomes the end users’ responsibility. They also facilitate user training to avert potential security breaches.
A company that encountered data loss due to misconceptions about the Shared Responsibility Model is Capital One.
In 2019, the Capital One data breach had far-reaching consequences, impacting more than 100 million customers across the United States and Canada. This breach emerged from a misconfigured firewall within the company’s cloud infrastructure, granting a hacker access to sensitive customer data stored on Amazon Web Services (AWS).
The breach originated from exploiting a firewall vulnerability, enabling unauthorized access to the AWS metadata service, which provided the hacker with credentials to access the cloud-based data.
The Capital One data breach is a stark illustration of how misunderstandings of the Shared Responsibility Model can lead to data breaches.
Cloud service providers, like AWS, employ this model to define provider and customer security roles. In this framework, the provider is responsible for securing the cloud infrastructure, while the customer is accountable for safeguarding the data and applications stored within the cloud.
In the Capital One case, the misconfigured firewall fell under the customer’s domain, whereas the vulnerability within the firewall was the provider’s responsibility.
