Aprenda AZure - Undercode Testing

The article discusses IT infrastructure services, Azure, cloud computing, and device management. Below are key details and practical steps to enhance your Azure and IT security skills.

You Should Know:

1. Basic Azure CLI Commands

To manage Azure resources efficiently, use the following commands:

 Login to Azure 
az login

List all subscriptions 
az account list --output table

Set a default subscription 
az account set --subscription "Your-Subscription-Name"

Create a resource group 
az group create --name MyResourceGroup --location eastus

2. Securing Azure Resources

Enable Multi-Factor Authentication (MFA) for Azure AD users:

 Install Azure AD module (PowerShell) 
Install-Module -Name AzureAD

Connect to Azure AD 
Connect-AzureAD

Enable MFA for a user 
Set-MsolUser -UserPrincipalName [email protected] -StrongAuthenticationRequirements @{}

3. Windows Device Management with PowerShell

Use PowerShell to manage devices in an IT environment:

 Get system information 
Get-ComputerInfo

Check installed software 
Get-WmiObject -Class Win32_Product | Select-Object Name, Version

Enable Windows Defender 
Set-MpPreference -DisableRealtimeMonitoring $false

4. Linux Security Commands

For securing Linux servers in an IT infrastructure:

 Check open ports 
ss -tulnp

Update system packages 
sudo apt update && sudo apt upgrade -y

Check logged-in users 
who

Enable firewall (UFW) 
sudo ufw enable 
sudo ufw allow 22/tcp  Allow SSH

5. Cloud Security Best Practices

Enable Logging in Azure:

az monitor diagnostic-settings create --resource /subscriptions/xxx/resourceGroups/MyGroup/providers/Microsoft.Compute/virtualMachines/MyVM --name MyDiagnosticSetting --workspace /subscriptions/xxx/resourcegroups/MyGroup/providers/microsoft.operationalinsights/workspaces/MyWorkspace --logs '[{"category": "Security", "enabled": true}]'

Use Key Vault for Secrets:

az keyvault create --name MyKeyVault --resource-group MyResourceGroup --location eastus

What Undercode Say

Mastering Azure and IT infrastructure requires hands-on practice with CLI, PowerShell, and Linux commands. Automate security policies, enforce MFA, and monitor logs to prevent breaches. Cloud management is critical for modern IT roles, so keep learning through labs and real-world implementations.
