One of the best practices for securing sensitive data in SaaS applications is to control the access and usage of data based on the device type. Managed devices are those that are enrolled and monitored by the organization’s IT department, and have security policies and controls applied to them. Unmanaged devices are those that are not under the organization’s control, such as personal laptops or mobile phones. Allowing downloads to managed devices but blocking them from unmanaged devices prevents data leakage and unauthorized access to sensitive data. This can be achieved by using a cloud access security broker (CASB) solution, such as Prisma SaaS from Palo Alto Networks, which can enforce granular policies based on device posture, user identity, and data sensitivity 12. References: 1: Securing SaaS applications on the cloud is a critical aspect of protecting sensitive data and maintaining the trust of customers. By implementing best practices, such as enhanced authentication, data encryption, Break Glass, and oversight, organizations can mitigate the security risks associated with SaaS applications2: Prisma SaaS - Palo Alto Networks

XDR (Extended Detection and Response) uses machine learning (ML) to detect threats by identifying patterns and anomalies. XDR ingests data from multiple sources — including endpoints, networks, servers, and cloud workloads — to provide a unified and correlated view of threats across the environment.

page 211 "Consolidating servers within trust levels: Organizations often consolidate servers within the same trust level into a single virtual computing environment: ... ... ... This virtual systems capability enables a single physical device to be used to simultaneously meet the unique requirements of multiple VMs or groups of VMs. Control and protection of inter-host traffic with physical network security appliances that are properly positioned and configured is the primary security focus."

Examples of serverless environments include Amazon Lambda and Azure Functions. Many PaaS offerings, such as Pivotal Cloud Foundry, also are effectively serverless even if they have not historically been marketed as such. Although serverless may appear to lack the container-specific, cloud native attribute, containers are extensively used in the underlying implementations, even if those implementations are not exposed to end users directly.
