Ασφαλίστε την Azure MySQL και PostgreSQL με τη χρήση Service Endpoints

Ασφαλίστε την MySQL και την PostgreSQL με τη χρήση Service Endpoints Σε προηγούμενο post, Ασφάλισε την Azure SQL Database μέσα σε ένα VNET χρησιμοποιώντας service endpoints, είδαμε πως μπορούμε να χρησιμοποιήσουμε τα Service Endpoints του Azure Virtual Network για να ασφαλίσουμε μια Azure SQL για πρόσβαση μόνο από εσωτερικό δίκτυο.   Σήμερα, το Microsoft Azure, ανακοίνωσε την γενική διαθεσιμότητα του Service Endpoints για MySQL και PostgreSQL. Αυτό δίνει την δυνατότητα να κόψουμε όλη την Publ

Ασφάλισε την Azure SQL Database μέσα σε ένα VNET χρησιμοποιώντας service endpoints

Για πολλούς, ένα πρόβλημα στο να χρησιμοποιήσουν την Azure SQL, είναι η δημόσια πρόσβαση. Μετά τα τελευταία Azure updates μπορούμε να χρησιμοποιήσουμε τα service endpoints ώστε να ασφαλίσουμε την Azure SQL μέσα σε ένα VNET. Ας ξεκινήσουμε λοιπόν να βάλουμε την Azure SQL μέσα σε ένα VNET. Ανοίγουμε το Azure Portal και ξεκινάμε να δημιουργήσουμε ένα VNET. Στο τέλος της σελίδας δημιουργίας έχει προστεθεί μια νέα επιλογή που λέγετε service endpoints. Το ενεργοποιούμε και επιλέγουμε το Microsoft.Sql.

Validate Azure Resource Move with Postman

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 optio

Use Web Application Firewall (WAF) Rules with the Front Door to protect your app

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 poli

Use Service Endpoints to protect an Azure Storage Account inside an Azure Azure Virtual Network

Use Service Endpoints to protect an Azure Storage Account inside an Azure Azure Virtual Network As we have already saw at a previews post, we can use the Service Endpoints to protect an Azure SQL Server inside an Azure Virtual Network. Today we will see how we can protect a Storage Account. First we need to enable the Microsoft.Storage Service Endpoint to an existing Virtual Network or create a new Virtual Network and enable it.

Use Azure Security Center to protect your workloads

Use Azure Security Center to protect your workloads At this series of posts we will make a walk along the Azure Security Center, to see some common usage scenarios. Like how we can use it to protect from a Virtual Machine to a whole Data Center. To make it easier to understand we will start with a typical Azure IaaS scenario. A Virtual Machine with IIS role to act as Web Server. The steps to create the VM is out this post’s scope. I will simply describe the process. First we create a Windows Ser

The simplest is to open a Command Prompt and type: “telnet yourexchangeserver 25” and press Enter The Command Prompt will start the telnet client and try to connect to the mail […] The post Test Exchange mail submission using SMTP commands appeared first on Proxima's IT Corner.

Set Static Private IP to an Azure VM

First of all, the VM must be within a virtual network to be able to add a static Private IP address   There are two ways to set a static private IP. One is using the new Azure Portal "portal.azure.com" and one via PowerShell.   Using the new Portal, browse a VM, select settings and then IP addresses. There at the Private IP address you can select "Static" and add the IP address.   Using PowerShell, first connect to the Azure (details on this post), and use the following commands:   #Test

Serverless Computing | Check your expired public certificates

Connect two or more Azure Virtual Networks using one VPN Gateway Peering is a feature that allows to connect two or more virtual networks and act as one bigger network. At this post we will see how we can connect two Azure Virtual Networks, using peering and access the whole network using one VPN Gateway. We can connect Virtual Networks despite if they are in the same Subscription or not. I have created a diagram to help understand the topology. We have a Virtual Network with Site-2-Site VPN

Serverless Computing | Email Report Azure WAF Logs

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.

Securely scale your Web Apps with Azure Front Door

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

Secure your Azure SQL locally inside your vnet using service endpoints

Secure your Azure SQL locally inside your vnet using service endpoints For many companies, a throwback of using Azure SQL was the Public Access. After the latest Azure updates you can use the service endpoints to Secure your Azure SQL locally inside your vnet! For the time, the feature is available only at the West Central US, West US 2, and East US regions but soon more will follow. So, lets secure your Azure SQL locally inside your vnet!

Using this benefit you can save up to 40% on a Windows Azure VM cost using your own license with software assurance. You just need to have a Windows Server Standard or Datacenter license with Software Assurance, and it is not restricted to any specific licensing program, it is available to all licenses with Software Assurance.

Reserve external IP on Azure Cloud Service

When we create a VM on Azure, at the same time we create a Cloud Service. Later we can create more VMs on the same cloud service. Each cloud service has a unique Public IP. For as long the Cloud Service has at least one VS running this Public IP remains the same. If all VMs of a Cloud Service are off then the Public IP is released and next time the VM is powered on it will take a new Public IP.   Using PowerShell we can reserve a Public IP for as long as the Cloud Service exists, with or witho

Remove/Add Microsoft Antimalware Service from an Azure VM

Microsoft offers for free it’s antimalware service. When you create a new VM you have the option to enable it. This will install the System Center Endpoint Protection client to the VM managed by Azure. If you have added this but now you want to remove it and add some other antivirus/antimalware solution you cannot do it by just uninstalling the client from the VM. The client will auto re-insalled by Azure. There are two ways to completely uninstall the program and remove it from Azure. One is us
