When moving applications to the public cloud, security remains the primary concern. Who is responsible when there is a data leak or when the application is affected?
This is why cloud providers use a liability model shared. This means that the customer is responsible for the security IN the cloud, while the cloud provider is responsible for the security OF the cloud. In other words, companies are still responsible for the security of their application, including cloud-native ones that take advantage of serverless architecture. These applications are still vulnerable to XSS, data breaches, DDoS, etc.
