Description Azure Virtual Network deployment provides enhanced security and isolation for your Azure Cache for Redis, as well as subnets, access control policies, and other features to further restrict access.When an Azure Cache for Redis instance is configured with a virtual network, it is not publicly addressable and can only be accessed from virtual machines and applications within the virtual network.

DisplayName: Azure Cache for Redis should reside within a virtual network
Description: Deploying Azure Cache for Redis within a Virtual Network (VNet) enhances security by providing isolation and restricting access.
This setup ensures that the cache instance is not publicly addressable and can only be accessed from within the VNet.
This includes access from virtual machines and applications.
Without this configuration, the cache instance could be exposed to potential threats and unauthorized access.
Therefore, for optimal security, we recommend housing Azure Cache for Redis within a VNet .

Remediation description: Injection into your custom Virtual Network/Subnet can only be done at cache creation time, so take these steps to mitigate: 1. Create and configure a new VNet-injected cache into your custom subnet for the Azure Cache for Redis. 2. Either embed your client application into the same virtual network or allow access for your client application to communicate with the cache instance within your subnet using NSG rules. Follow the guidance here: https://aka.ms/redis/vnet-faq 3. If necessary, export the data from your instance and import it into the new Azure Cache for Redis instance. Learn more about the import/export feature here: https://aka.ms/redis/import-export.

Azure_Security_Benchmark_v2.0 NS-2 Azure_Security_Benchmark_v2.0_NS-2 Azure Security Benchmark NS-2 Network Security Connect private networks together Customer Use Azure ExpressRoute or Azure virtual private network (VPN) to create private connections between Azure datacenters and on-premises infrastructure in a colocation environment. ExpressRoute connections do not go over the public internet , and they offer more reliability, faster speeds, and lower latencies than typical internet connections. For point-to-site VPN and site-to-site VPN, you can connect on-premises devices or networks to a virtual network using any combination of these VPN options and Azure ExpressRoute. To connect two or more virtual networks in Azure together, use virtual network peering or Private Link. Network traffic between peered virtual networks is private and is kept on the Azure backbone network.
