Unravel the complexities of cloud security with our guide to the shared responsibility model. Learn who's responsible for what when it comes to SaaS applications, and discover how to safeguard your data.
Whether you’re an IT manager, security professional, or part of a small business team, understanding the security roles in cloud computing is crucial.
With 93% of enterprises now using public cloud services, knowing who is responsible for what is key to keeping your data safe.
This article is here to help IT and security teams get to grips with the essential roles and responsibilities in cloud computing, especially when it comes to SaaS applications. We'll break down the shared responsibility model and provide practical tips to help you enhance your business’ data security.
Let's dive in and see how you can stay secure in the cloud.
In essence, the shared responsibility model is all about knowing who’s responsible for what when it comes to securing data and applications in the cloud.
When you move your data and applications to the cloud, you’re not alone in keeping everything secure – both you and your cloud provider have roles to play.
Think of it this way: in a traditional on-premises IT setup, your IT team takes care of everything. They handle the physical security of your data centre, the hardware, networking, operating systems, and the applications running on them.
But when you shift to the cloud, the responsibilities get shared. The cloud provider takes care of securing the underlying cloud infrastructure, like the physical servers and networking gear. Meanwhile, you’re responsible for your data, applications, and any other assets you run in the cloud.
When diving into cloud computing, it’s helpful to know about the different service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Each model has its own set of responsibilities for both the provider and the user.
With IaaS, the provider takes care of the basic infrastructure—think servers, storage, and networking—along with physical security. You’re in charge of everything above that, like the operating systems and your data. It’s a flexible option, and the IaaS market, which was worth $130.08 billion in 2023, is expected to grow to a whopping $738.11 billion by 2032.
PaaS offers more than just infrastructure; the provider also manages the platform for your applications, including operating systems and databases. Your job is to handle the security of your apps and data. PaaS simplifies the development process, and its market is set to expand from $171.80 billion in 2024 to $386.90 billion by 2029.
With SaaS, the provider takes on almost all responsibilities—from the infrastructure to the software applications. You’ll mainly focus on configuring the software and managing user access. The SaaS market is booming, expected to reach $818.80 billion by 2029, highlighting its growing role in business.
Grasping these models helps you navigate your cloud responsibilities more effectively, keeping your cloud environment secure and running smoothly.
When it comes to SaaS applications, the shared responsibility model plays a crucial role in defining who handles what in terms of security. Let’s break it down:
For SaaS providers, the responsibility is quite extensive. They manage everything from the underlying infrastructure—servers, storage, and networks—to the application itself. This includes ensuring the security of the software, maintaining the operating environment, and handling data centre security. Essentially, they take care of most of the heavy lifting when it comes to security.
On your end as a SaaS user, your responsibilities primarily involve managing and securing your own data and access.
This includes configuring the software correctly, setting up proper user access controls, and ensuring that data encryption and protection measures are in place.
Although the provider handles most of the security, your vigilance in these areas is key to keeping your data safe.
User responsibilities might seem less extensive compared to what the provider handles, but they’re no less important. For instance, in the past year, 96.7% of organisations using SaaS applications experienced at least one security incident.
Clearly, users still need to remain proactive about data protection and access management. Your role in configuring and monitoring your SaaS applications can significantly impact your overall data security posture.
When it comes to cloud computing, there are several areas where both the provider and the user need to collaborate closely to ensure comprehensive security.
This shared responsibility model means that while the cloud provider handles the bulk of the infrastructure and application security, users also have vital roles to play.
One key area of overlap is security monitoring. Although cloud providers set up comprehensive monitoring systems for their infrastructure, it’s essential for users to keep an eye on their own data and applications.
This means being alert to any unusual activity or potential threats within their specific environment.
Compliance is another example where responsibilities are shared. While providers ensure their services comply with relevant standards and regulations, users must ensure that their own data usage and configurations also meet compliance requirements.
This often involves configuring settings to match regulatory needs and regularly reviewing policies to stay up to date.
Despite the clear division of tasks, there’s a common misconception. In fact, 69% of organisations mistakenly believe that cloud service providers are fully responsible for data protection, privacy, and compliance.
This misunderstanding can lead to gaps in security and compliance, so it’s important for you to know and fulfil your own responsibilities in the cloud environment.
Navigating the shared responsibility model can be tricky, with several key challenges that organisations need to address.
Understanding how to effectively manage cloud security involves a few key best practices that can make a big difference.
First and foremost, get to grips with your Service Level Agreements (SLAs) and the specific policies of your cloud provider.
These documents outline the security responsibilities of both parties, so knowing them inside out helps prevent misunderstandings and gaps in security coverage.
Data protection is another critical area. Ensure that you have robust measures in place for data security, such as encryption and access controls.
While your provider handles the underlying infrastructure, you are responsible for securing your own data.
To enhance data security, consider using third-party Data Loss Prevention (DLP) tools like Metomic, which can help safeguard sensitive information and manage data access more effectively.
Managing user credentials effectively is vital. This includes setting up strong authentication mechanisms and regularly reviewing access permissions.
A significant proportion of security incidents are linked to poor credential management (with 86% of data breaches involving stolen credentials), so it's crucial to handle this aspect with care.
Cloud providers frequently update their services, which can impact your security settings.
Keep an eye on these updates to ensure that any changes do not inadvertently create vulnerabilities. Regularly reviewing update notifications helps you stay ahead of potential security issues.
Finally, take advantage of tools designed to simplify and enhance cloud security management.
These can range from automated security monitoring to dashboards that provide a clear view of your cloud environment.
Using these tools can help you maintain a secure setup and quickly address any issues that arise.
