Azure Application Gateway WAF Rules Evaluation
In this short article I will give an example of how the evaluation of the "WAF Custom Rules" and "Managed Rules" of the "Azure Application Gateway" works.

Application Gateway WAF v2 Custom Rules
The Application Gateway WAF v2 has brought some new features compared to v1, including the ability to create "WAF Custom Rules". In this short article I would like to discuss these "Custom Rules" and show how you can successfully create them. I have added some hints to the article that are difficult or impossible to find in the Microsoft documentation.
Accelerate Azure VM network performance
You come across them more often than you would hope. Non-redundant infrastructure solutions based on a few virtual machines (VM). In this article, I'll go over some little tricks you can use to speed up network performance for your Azure VM in such a scenario.
Certificate-based Point to Site Azure VPN through Intune
As the business world becomes increasingly mobile, cloud services are becoming even more attractive. But what if, as is often the case, there are still dependencies on an enterprise network - on Azure, for example? The solution is obvious: a point-to-site VPN ensures communication for mobile workers. In this how-to post, I discuss how a certificate-based point-to-site VPN to an Azure VPN gateway can be automatically rolled out to mobile clients through Intune. I also discuss how certificates can be automatically issued and renewed by a Certificate Authority in combination with Intune.
ARM template deployment – Hub and Spoke with Bastion
With an Azure Resource Manager (ARM) template, you can create a specific infrastructure on Azure with the click of a button. The template defines the infrastructure as code and Azure is thereby told the target state of the resources. I have created such a template and published it via Github. The ARM template deployment includes a hub and spoke network topology with a central Azure bastion for secure access to VMs. This post shows you step by step how to use the template for yourself.
Use Azure Bastion with VNet peering
The Microsoft PaaS "Azure Bastion" is a popular service to make your Azure networks more secure. However, until now there was a drastic limit. Azure Bastion could only be used in the same VNet. VMs in a peered network could not be accessed via Bastion. This circumstance pushes up the costs, because with a hub-and-spoke topology you have to place a bastion in each VNet. But these times are over. Use Azure Bastion with VNet peering (since 05.11.2020 in preview).
Azure Bastion - Secure access to Azure VMs
The work forms "home office", "remote work" or even "work anywhere" are becoming increasingly important, especially in recent months. This change affects not only users, but also IT staff and system administrators. However, I am often confronted with mistrust and security concerns when dealing with such issues. This is where Azure Bastion comes into play. Bastion not only enables "work anywhere" for system administrators, but also provides increased security and secure access to your Azure VMs without the need for a VPN!
Azure Bastion Planning and Implementation
Azure Bastion is an Azure service that allows you to access your Azure VMs securely and centrally via the web portal. This allows you to enable your system administrators and system specialists to "work anywhere" without any security concerns. In this article I will not focus on the service itself, but rather on the steps necessary to plan and implement Azure Bastion.
