2. What are Azure Active Directory Conditional Access policies, and how do they enhance security?

Azure Active Directory Conditional Access policies define access rules for Azure AD resources, enhancing security by requiring specific conditions before granting access. Key components include:

• Conditions: Criteria like user membership, IP location, and device state that must be met for policy application.
• Controls: Actions such as requiring MFA or blocking access when conditions are met.
• Assignments: Specifies who the policy applies to, like users or groups.

These policies ensure only authorized users and devices access sensitive resources, reducing unauthorized access risks.

3. Describe the process of setting up Azure Key Vault and its use cases.

Azure Key Vault securely stores and manages sensitive information like secrets, keys, and certificates. To set it up:

• Create an Azure Key Vault instance.
• Define access policies for control.
• Add secrets, keys, and certificates.
• Integrate with applications to securely retrieve stored data.

Use cases include secret management, key management, certificate management, and access control.

4. Write an ARM template snippet to create a storage account with secure transfer required.

To create a storage account with secure transfer required using an ARM template, set the supportsHttpsTrafficOnly property to true. This ensures data transfer over HTTPS, enhancing security.

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "resources": [

    "location": {
      "type": "string"
    }
  }
}

5. Explain the difference between Role-Based Access Control (RBAC) and Azure AD Privileged Identity Management (PIM).

Role-Based Access Control (RBAC) provides fine-grained access management of Azure resources, assigning roles to users, groups, and applications. It ensures users have only necessary permissions. Azure AD Privileged Identity Management (PIM) manages and monitors access to important resources, offering just-in-time privileged access and features like access reviews and activity logging.

6. How would you set up logging and monitoring for an Azure SQL Database to detect potential security threats?

To set up logging and monitoring for an Azure SQL Database:

• Azure Monitor: Collects and analyzes telemetry from environments.
• Azure Security Center: Provides security management and threat protection.
• Azure SQL Auditing: Tracks database events and writes to an audit log.
• Advanced Threat Protection: Detects unusual and potentially harmful access attempts.

Steps include enabling diagnostic settings, configuring auditing, setting up alerts, and enabling Advanced Threat Protection.

7. Describe the steps to configure Azure Sentinel for threat detection and response.

To configure Azure Sentinel for threat detection and response:

1. Create an Azure Sentinel Workspace: Establish a central hub for threat activities.
2. Connect Data Sources: Integrate various data sources for security data collection.
3. Set Up Analytics Rules: Configure rules to detect suspicious activities.
4. Create Workbooks: Visualize and monitor collected data.
5. Configure Incident Response: Set up automated response actions.
6. Monitor and Investigate Incidents: Regularly monitor and investigate incidents.

8. How does Azure Private Link enhance security for PaaS services?

Azure Private Link enhances security for PaaS services by providing private connectivity from a virtual network to Azure services, keeping traffic off the public internet. Benefits include:

• Data Protection: Minimizes risk of data exfiltration.
• Compliance: Ensures data remains within a trusted network.
• Reduced Latency: Improves performance by avoiding the public internet.
• Access Control: Manages who can access services.

9. Write a Terraform script to deploy an Azure Kubernetes Service (AKS) cluster with network policies enabled.

To deploy an Azure Kubernetes Service (AKS) cluster with network policies enabled using Terraform:

provider "azurerm" {
  features {}
}

resource "azurerm_resource_group" "aks_rg" {
  name     = "aks-resource-group"
  location = "East US"
}

resource "azurerm_kubernetes_cluster" "aks_cluster" {
  name                = "aks-cluster"
  location            = azurerm_resource_group.aks_rg.location
  resource_group_name = azurerm_resource_group.aks_rg.name
  dns_prefix          = "aksdns"

  default_node_pool {
    name       = "default"
    node_count = 1
    vm_size    = "Standard_DS2_v2"
  }

  network_profile {
    network_plugin = "azure"
    network_policy = "azure"
  }

  identity {
    type = "SystemAssigned"
  }
}

output "kube_config" {
  value = azurerm_kubernetes_cluster.aks_cluster.kube_config_raw
  sensitive = true
