In the Infrastructure as a Service (IaaS) model, the end-user customer has a greater degree of responsibility for security incidents because they are provided with the greatest level of control over the resources they are using. Unlike in Software as a Service (SaaS), where the service provider manages much of the security layer, end-users in IaaS environments are responsible for configuring, managing, and securing their own virtual machines, networking, and storage.

This means that the end-user customer must implement appropriate security measures, such as firewalls, access controls, and data encryption, in order to protect their applications and data. They are also responsible for compliance with relevant regulations and standards, and any vulnerabilities or incidents resulting from misconfigurations or failure to adopt proper security practices fall largely on their shoulders.

While the Cloud Service Provider does manage the underlying infrastructure and typically ensures the security of that infrastructure, the onus to secure data and workloads deployed within that infrastructure rests with the end-user customer.
