Certified Incident Handler (CIH) Practice Ecam

What is a responsibility of cloud customers for protecting their applications in a PaaS environment during a security incident?

1. Backing Up Data

2. Responsible for Applications and Their Security

3. Monitoring Network Traffic

4. Patching Operating Systems

The correct answer is: Responsible for Applications and Their Security

In a Platform as a Service (PaaS) environment, the shared responsibility model delineates the roles of the cloud provider and the customer regarding security. While the cloud provider manages the underlying infrastructure, the customer is responsible for managing and securing their applications hosted on that platform. This includes ensuring that applications are coded securely, maintaining access controls, performing vulnerability assessments, and implementing necessary safeguards against potential threats. By taking responsibility for applications and their security, customers also need to understand their unique application environments and the specific security implications that come with them. This responsibility empowers cloud customers to effectively respond to security incidents through proper risk management strategies tailored to their business needs. This proactive approach is crucial in minimizing damage during a security incident, maintaining application performance, and protecting sensitive data that the application may process. In contrast, while backing up data, monitoring network traffic, and patching operating systems are important practices, they fall more under responsibilities that involve operational procedures rather than specific accountability for application security in a PaaS framework.
