New Blog | Monitoring traffic flows in Azure Firewall using Virtual Network Flow Logs

By Gustavo Modena

 

Azure Firewall is a managed service designed to protect your Azure Virtual Network resources, providing advanced threat protection and advanced logs and metrics that are essential tools for monitoring and managing your network security. By leveraging both logs and metrics, you can ensure the overall health and efficiency of your firewall, maintain an audit trail of configuration changes, and comply with security and auditing requirements.

 

In this blog post we will show you a different approach to enhance the monitoring experience of Azure Firewall by using Virtual Network Flow Logs and Traffic Analytics. This combination provides a comprehensive view of traffic flows within your network, offering deeper insights for analysis and investigation, helping to identify traffic deviation that may indicate a security issue and identify applications that are consuming Azure Firewall the most.

 

What are Virtual Network Flow Logs and Traffic Analytics?

Both Virtual Network Flow logs and Traffic Analytics are features of Azure Network Watcher that collects information about network traffic and enriches raw flow logs to provide insights into network traffic patterns, including source and destination IP addresses ports protocols and the volume of traffic. To learn more about both features, check out the product documentation.
