network security groups
3 TopicsNetwork Monitoring
Hi, I recently applied Network Security Groups on Virtual Networks (NSG). Now my question is, is it possible to monitor / record the network traffic? For example, I've configured many rules on the NSG, now a application on a Server won't work and my first guess is the NSG is blocking the communication. How do I see now which port the application is using so I can set a new rule to the NSG? I know when you already know the port you can check it in Network Watcher "IP flow verify and NSG diagnostics" as a whatif state. Traffic Analytics isn't the right answer too or am I seeing it wrong? Vnet Flow Logs should be the right thing. I configured it, applied traffic analytics and a account storage. Applied it for testing on a nic but I don't see anything practical for my use? The only thing Iwish is to see live or logged the traffic if the NSG blocked anything and troubleshoot.249Views0likes4CommentsAzure NSG insecure inbound/Outbound access rules
Hello all, my Azure subscription has security groups that allow unrestricted inbound or outbound access on port and protocol combinations. Allowing unrestricted inbound/ingress or outbound/egress access can increase opportunities for malicious activity such as hacking, loss of data, and brute-force attacks or Denial of Service (DoS) attacks. How can I configure the allowed ports by assigning a policy to my subscription. Is there a built-in policy for that?4.1KViews2likes2CommentsAzure network rules - statefull firewall
Hello Team, There are so many different types of network rules in Azure. For example those defined for cloud services: https://msdn.microsoft.com/en-us/library/azure/gg557551.aspx Or network security groups for VM traffic. Are any of those statefull firewalls ? Do we track TCP sessions ? And accept return traffic by default ? For example inbound security rules in NSG: it looks like returning traffic is accepted by default ? Assuming it's matching corresponding session (so we need to track TCP sessions). Are we statefull then ? Thanks,Solved1.3KViews0likes1Comment
