# Infrastructure protection
<a name="infrastructure-protection"></a>

 Infrastructure protection for hybrid networking involves securing all networking resources from your on-premises deployment to the cloud. Enforcing boundary protection, monitoring points of ingress and egress, and comprehensive logging, monitoring, and alerting are all essential to an effective information security plan. 


| HNSEC04: How do you implement network isolation in hybrid environments? | 
| --- | 
|   | 

 Hybrid network architecture creates complex challenges for resource isolation as security boundaries span both on-premises and cloud environments. Organizations must maintain effective separation between security domains while preventing security incidents from propagating across network boundaries, particularly for sensitive workloads requiring stringent protection.
