Data exfiltration protection access controls
Microsoft Defender for Cloud Apps
Actions that would compromise the security of customer data must be detected and prevented.
For example, employees may be using an unapproved cloud application for storing sensitive corporate data or downloading a vast number of sensitive files for exfiltration. These actions can be prevented by Microsoft Defender for Cloud Apps.
Box 2: Microsoft Defender for Office 365
Block Microsoft Teams messages that contain potentially malicious content by using zero-hour auto purge (ZAP).
Zero-hour auto purge (ZAP) is a feature of Microsoft Defender for Office 365.

Bastion provides secure remote access.
It uses RDP/SSH session is over TLS on port 443.
Note: Azure Bastion is a service you deploy that lets you connect to a virtual machine using your browser and the Azure portal. The Azure Bastion service is a fully platform-managed PaaS service that you provision inside your virtual network. It provides secure and seamless RDP/SSH connectivity to your virtual machines directly from the Azure portal over TLS. When you connect via Azure Bastion, your virtual machines don't need a public IP address, agent, or special client software.
Lock down inbound traffic to your Azure Virtual Machines with Microsoft Defender for Cloud's just-in-time (JIT) virtual machine (VM) access feature. This reduces exposure to attacks while providing easy access when you need to connect to a VM.
Meets the requirement: Only provide permission to connect the virtual machines when required Reference:

When you create a communication compliance policy or a policy for retention, you can create or add an adaptive scope for your policy. A single policy can have one or many adaptive scopes.
An adaptive scope uses a query that you specify, so you can define the membership of users or groups included in that query. These dynamic queries run daily against the attributes or properties that you specify for the selected scope. You can use one or more adaptive scopes with a single policy.

Application deployments with GitOps (Flux v2) for AKS and Azure Arc-enabled Kubernetes GitOps on Azure Arc-enabled Kubernetes or Azure Kubernetes Service uses Flux, a popular open-source tool set. Flux provides support for common file sources (Git and Helm repositories, Buckets, Azure Blob Storage) and template types (YAML, Helm, and Kustomize).
Flux is deployed directly on the cluster, and each cluster's control plane is logically separated.
This makes it scale well to hundreds and thousands of clusters. Flux enables pure pull-based GitOps application deployments. No access to clusters is needed by the source repo or by any other cluster.
