 ### Azure resources
 
-One layer of security lies with the Azure resources that your Microsoft Connected Cache nodes communicate with. You should ensure that your organization’s Azure tenant is using role-based access control (RBAC) to apply policies that enforce least-privilege access to the Connected Cache Azure resources you provision. Only trusted individuals should have the ability to perform create, read, update, and delete (CRUD) operations on your organization’s MCC Azure resources and cache nodes.

 You can learn more about the principles of Azure resource security by referring to the [Azure identity management and access control security best practices](/azure/security/fundamentals/identity-management-best-practices) and the [Microsoft cloud security benchmark (MCSB) documentation for Identity management](/security/benchmark/azure/mcsb-identity-management).
 
 ### Local network
 
-Another layer of security lies with your organization’s local network. It's recommended that your organization adopts a Zero Trust approach to network security so that your organizational data is protected even if an attacker breaches your network perimeter.

 One best practice is to utilize a firewall on your organization's network. When using a network firewall, you should configure it to allow communication between your Connected Cache nodes and the [Microsoft and CDN endpoints](delivery-optimization-endpoints.md) used to install Connected Cache and download Microsoft content.
