  1. Azure Virtual Network Gateway provides the ability to connect to your Azure Virtual Network with Azure Client VPN (SSL) connections using your Azure AD or hybrid identity, with Multi Factor Authentication (MFA) and your Conditional Access policies. We can have an Enterprise grade SSL VPN, with Active Directory authentication and Single Sign on (SSO) from your corporate laptops and apply all your conditional access policies, like MFA, Compliance devices, trused locations, etc. How to create the VPN Gateway Go to your Virtual Network’s subnets and create a Gateway subnet by clickin
  2. Compliance Report using Azure Policy Azure Policy is a powerful tool for Azure Governance. With Azure Policy we can define rules for all Azure Subscriptions the we manage. We can use this rules for simple limitation actions, like permitting only specific VM Series and Sizes that can be created and also more complex rule sets that helps you standardize the whole Azure deployment. At my previous posts, we learned How to limit the Azure VM Sizes and How to enforce tags for resources creation At the current post we will learn how to use Azure Policy to have a compliance report for our dep

  6. At the previous post we created an Azure Front Door to scale our web apps across Azure Regions and also publish them only through the Front Door’s URL. At this post we will create Web Application Firewall (WAF) rules, to protect our web apps. To add WAF functionality to the Front Door we need first to create WAF rules and then attach them to the Front Door Create the WAF Rule From the Azure Marketplace search for WAF and create a Web Application Firewall At the “Create a WAF policy” wizard select “Global WAF (Front Door) for policy, provide the subscription and resource group, g
  7. Securely scale your Web Apps with Azure Front Door There is a big buzz out there about Azure Front Door. Is it a Load Balancer? A CDN? A Traffic Manager? A Web Application Firewall ? A Reverse Proxy? An Application Gateway? So, what is Azure Front Door? Azure Front Door actually is all the above and more. It is a global service, that routes web traffic based on performance and availability. A Layer 7 multi-region load balancer with Web Application Firewall (WAF) capabilities, DDoS protection & CDN. Azure Front Door is the entry point, the edge, of all Microsoft’s WAN. All Microsoft serv
  8. <h1 style="text-align: justify;">Azure Portal | Playing with Disk Snapshot</h1> <p style="text-align: justify;">Disk Snapshot is a powerful tool to manage Azure VMs. It’s simple to create and can help the administrators in various tasks. It’s a fast and efficient way to have a crash-consistent Disk of a Virtual Machine, before performing tasks, updates, configuration changes, application installations, etc. Of course the last line of defence is the Azure Backup, but using the Snapshot you don’t need to wait the whole Backup / Restore times. With snapshots there are two main o

  17. Validate Azure Resource Move with Postman At this post we will see how easily we can move azure resources to new resource groups or subscriptions and how we can validate if the azure resources are eligible to move without initiate the move. Move Azure Resources to new resource groups or subscriptions Azure Resource Manager allow you to easily move resources to new resource groups or subscriptions. It is a pretty simple process. From the Azure Portal, open a Resource Group, and from the top options click Move. You can select if you want to move to another resource group or subscription. On the
  18. Azure VM CMD & PowerShell from the Portal Today I was trying to troubleshoot an Azure VM. This VM is behind a Network Virtual Appliance (NVA) and at the subnet it has User Defined Routes (UDR) that routes the traffic to the NVA. We was troubleshooting the NVA and it was not possible to connect with RDP to the VM. Serial Console This is an excellent scenario to use the Serial Console. From the Azure Portal, portal.azure.com, navigate to the Azure VMs blade, scroll down to the Support + Troubleshooting section and select “Serial Console” The Serial Console will initialise and after a while
  19. Azure Policy | Limit the Azure VM Sizes Azure Governance This post, Azure Policy, is the first of a series of posts about Azure Governance. The idea is to explain through examples and how-to-guides, the tools that Microsoft Azure provides to help the administrators to enforce rules to all subscriptions. Some examples of those rules are, to help the organizations to stay compliant with their corporate standards, to standardize the resources creation and management, to manage the permissions and access controls, etc. Azure Policy Azure Policy is a powerful tool for Azure Governance.

  21. Azure Web Application Firewall (WAF) is a function of the Azure Application Gateway that detects and prevents exploits and attacks to a web application. Using a WAF we add an additional security layer in front of our application. To have a sneak peak at the most common web application attacks, take a look at the OWASP Top 10 Most Critical Web Application Security Risks . At my previous posts we have seen how to Protect your Web App using Azure Application Gateway Web Application Firewall and Use Log Analytics to Query the WAF Logs and email those logs to the Admins. At this post I want to shar
  22. At this post, we will create a Logic App that will query the Log Analytics workspace for the WAF logs of the last 24 hours and send the results in an email, using a free SendGrid account. A Web Application Firewall protects your application from common web vulnerabilities. Azure provides enterprise grade Web Application Firewall through the Application Gateway.

  24. Working as a Cloud Consultant, Administrator, Architect, many companies will provide you guest (Azure AD B2B) access to their subscription. After completing the Admins of the subscriptions, many times, forget to remove this accesses and as a result you still have access to resources with no reason and also the list of your available subscriptions grows making it difficult to choose the right subscription to work. In this post we will walk through the steps of removing your account from those subscriptions. Since this is an identity matter, you need to login to the https://account.activedirecto
