Getting Started with Azure Portal
The best way to learn about the navigating the Azure Portal is by trying it to solve something for us.
As an example and to get familiar with the Azure Portal, let's create a Ubuntu based Virtual Machine
Create a Resource Group
From the burger menu, select Resource Groups and create a new resource group. You can also use the same resource group that you created in the previous chapter for Azure Cloud shell.
All the services we use can be made to operate within a resource group. This makes it easier to delete the objects all at once instead of independently removing them.
Creating an Ubuntu based Virtual Machine
Creating a new virtual machine in Azure Portal is all about doing the following
Choose the base operating system for the virtual machine (VM)
Choose under which resource group will the VM run
Fill in the values
for region where the VM should spin up
select a VM size
add a user and SSH key for access
open a port to allow SSH access
Once the VM is created, use the provided information to login
The first step is to start by clicking on resource groups
In this example, Resource Group name is bapazure. Please use the Resource Group name that you have created.
Click on add and type Ubuntu Server 18.04 LTS
Click the Create button at the bottom
Creating a Virtual machine by filling a form
Fill information about the resource group name in project details
Fill in instance details
Select a VM size by clicking on Change Size. Select B1s for now.
SSH key details. Read the public key from the student VM by cat ~/.ssh/id_rsa.pub
Inbound port information
Configuration validated
Deployment is underway
Deployed
Connecting to our newly setup virtual machine
Once VM is up, SSH to it
SSH information we need to for connecting. Step 4 is what you need. Your private key is already added to ssh agent on the student machine. Use the command without the -i flag else to follow the screen, the private key is the ~/.ssh/id_rsa file on the student machine.
A complete Ubuntu Server setup on the internet for our use in less than 5 minutes
Additional Exercise
As an exercise to continue practising after the training, attempt to do the following
Configure the Azure Virtual Machine's firewall to allow SSH access only from the attacker machine
Make a copy of the private key from the student machine's
~/.ssh/id_rsafolder or add a new public key to the Azure virtual machineVerify that the Azure Virtual Machine firewall allows access as per the rules you have defined
