How to Manage Your SaaS Responsibilities and Risks
Introduction
If you run a business, you probably use one or more software-as-a-service (SaaS) solutions from different vendors. In this blog post, I want to explore the implications of this common practice for the shared responsibility model and the shared responsibility matrix that applies to the contract between your business or organization and the service provider.
Example of a SaaS Solution: Microsoft 365
Let’s take Microsoft 365 as an example of a SaaS solution. When someone from your business or organization signs up for this service, they agree to the Terms of Use or Terms of Service that Microsoft has set. This means that they are legally bound by the conditions and obligations that Microsoft has defined.
But what exactly are those conditions and obligations? And what are the responsibilities that you and Microsoft share when it comes to the security and performance of the service? To answer these questions, we need to look at the Shared Responsibility Model that Microsoft has published here.
Understanding the Shared Responsibility Model
This model shows how the responsibility for different aspects of the service varies depending on the type of cloud service model: SaaS, PaaS (Platform-as-a-Service), or IaaS (Infrastructure-as-a-Service). For this topic, we will focus only on the first column, SaaS. If we examine the items marked with “Responsibility always retained by the customer”, we can see that the customer is always responsible for the following:
- The information and data that they store and process using the service.
- The devices that they use to access the service.
- The accounts and identities that they create and manage for the service.
This means that you, as the customer, must ensure that your data is protected, your devices are secure, and your accounts and identities are properly configured and controlled. Microsoft, on the other hand, is responsible for most of the other aspects of the service, such as the physical infrastructure, the network, the operating system, the application, and the security measures. However, there is one area where you and Microsoft share some responsibility: the identity and directory infrastructure. This means that you must work with Microsoft to ensure that the authentication and authorization mechanisms for the service are aligned with your business needs and policies.
Implications for Your Business Decisions
So, what does all this mean for you, the customer, when you are making decisions related to who should provide Information Technology or Cybersecurity services for your business? For example, how many different SaaS applications does your vendor bundle together to provide their service for your business? Have you had a discussion with your vendor about who is responsible for what?
The reason this is important becomes evident when regulatory requirements begin to affect your business. For instance, if you are subject to the Payment Card Industry (PCI) Data Security Standard (DSS), Criminal Justice Information Services (CJIS) Security Policy, Gramm-Leach-Bliley Act (GLBA) or the California Consumer Privacy Act (CCPA), you need to know how your data is collected, stored, processed, and shared by the SaaS providers that you use. You also need to know how you can exercise your rights and obligations under these regulations, such as the right to access, rectify, erase, or port your data. You cannot simply assume that the SaaS provider will take care of everything for you. You need to understand the shared responsibility model and the shared responsibility matrix that apply to each SaaS solution that you use, and make sure that you comply with the terms and conditions that you have agreed to. Similarly, you cannot assume that your Managed Service Provider (MSP) or Cloud Service Provider (CSP) is taking care of these things either, unless you have explicitly agreed that they are “managing” your environment. Otherwise, the MSP or CSP is fulfilling the task of informing and consulting you, but not acting on your behalf. If you are being managed by an MSP or CSP, then there will be a shared responsibility between both parties, and you need to clarify the scope and extent of that responsibility.
