Build a practical Azure security lab with Terraform. The lab creates a small hub-spoke environment where an untrusted test client reaches a protected workload only through controlled network paths. Azure Firewall Basic sits in the hub, NSGs and route tables enforce segmentation, Key Vault stores generated secrets, Log Analytics collects diagnostics, and Azure Policy audits posture.

The design follows the same style as the Azure Landing Zone Lab: clear feature toggles, reusable modules, diagrams, wiki pages, CI checks, and hands-on validation steps.

> Cost note: Azure Firewall is the main cost driver. In West Europe, Azure Firewall Basic is roughly 0.40 USD/hour plus data processing, so a full month can be about 292 USD before other resources. Deploy it for practice, validate the scenario, then destroy the lab.

## Wiki-Style Knowledge Map

Use this repository like a compact security-lab encyclopedia: the root README is
the landing article, and the `wiki/` folder is the linked body of knowledge.

## Master Control Panel

The main toggles live in `terraform.tfvars.example` and `environments/lab.tfvars`.

```hcl
deploy_firewall                = true
firewall_sku_tier              = "Basic"
force_spoke_egress_to_firewall = false

enable_test_client_public_ip = true
deploy_bastion               = false

deploy_entra_test_users   = false
deploy_conditional_access = false
deploy_sentinel           = false
deploy_soc_content        = false
deploy_endpoint_telemetry = false
deploy_identity_domain    = false
deploy_sentinel_playbooks = false
deploy_defender_for_cloud = false
deploy_sentinel_defender_connectors = false

deploy_keyvault      = true
deploy_log_analytics = true
deploy_policy        = true
deploy_budget        = true
```

The default keeps the lab easy to access with a restricted public RDP rule on the test client. Set `admin_source_ip_cidr` to your own public IP with `/32`.

## Overview

This Terraform project creates a focused security lab, not a full enterprise landing zone. It is built to make security controls visible and testable without deploying a large stack.

### Core Components

- Hub VNet: central connectivity and Azure Firewall subnet.
- Test spoke: untrusted Windows test client with optional restricted public RDP.
- Protected spoke: Windows IIS web VM without public IP.
- Azure Firewall Basic: east-west routing, web allow rules, explicit admin-protocol deny example.
- NSGs: subnet-level allow and deny rules.
- Route tables: force test-to-protected and protected-to-test traffic through the firewall.
- Key Vault: generated Windows admin password and lab details.
- Log Analytics: firewall and Key Vault diagnostics.
- Azure Policy: audit-mode posture controls.
- Budget: subscription budget alerts through Owner contact role.

### Optional Components

| Component | Toggle | Default | Notes |
|---|---:|---:|---|
| Azure Bastion | `deploy_bastion` | `false` | Easier private access, but adds hourly cost. |
| Entra test users/groups | `deploy_entra_test_users` | `false` | Requires directory permissions and `entra_domain_name`. |
| Conditional Access | `deploy_conditional_access` | `false` | Report-only MFA policy, requires Entra ID P1/P2. |
| Microsoft Sentinel | `deploy_sentinel` | `false` | Useful for SOC labs, but ingestion can increase cost. |
| SOC content | `deploy_soc_content` | `false` | Sentinel detections, watchlists, workbook, and hunting queries. |
| Endpoint telemetry | `deploy_endpoint_telemetry` | `false` | Azure Monitor Agent for Windows events, Defender operational logs, and performance counters. |
| AD DS identity lab | `deploy_identity_domain` | `false` | Adds a domain controller and domain-joins lab VMs. |
| Sentinel playbooks | `deploy_sentinel_playbooks` | `false` | Adds automation rules and a Logic Apps incident playbook. |
| Defender for Cloud | `deploy_defender_for_cloud` | `false` | Requires licensing and can add cost. |
| Defender connectors | `deploy_sentinel_defender_connectors` | `false` | Requires Defender XDR/Sentinel tenant permissions. |
| Spoke default egress via firewall | `force_spoke_egress_to_firewall` | `false` | Keep false when using public RDP to avoid asymmetric routing. |

## Lab Scenarios

The wiki now includes a Microsoft Learn-style path with objectives, diagrams,
exact validation commands, expected results, troubleshooting, cleanup, and
product reference links. Start with [the wiki index](wiki/README.md), then use
[the final validation checklist](wiki/get-started/final-validation.md) before
sharing or pushing the lab. For a pre-commit proof pass, use the
[final-check runbook](wiki/runbooks/final-check.md) and the
[security test matrix](wiki/reference/security-test-matrix.md).

### Scenario 1: Firewall in the Middle

Objective: prove that private spoke-to-spoke traffic crosses Azure Firewall.

Expected result:

- `curl http://PROTECTED_PRIVATE_IP` succeeds from the test client.
- RDP or WinRM from test to protected fails.
- Firewall logs show allowed web flows and denied admin attempts.

### Scenario 2: Network Segmentation

Objective: understand how NSGs and UDRs work together.

Controls:

- Protected VM has no public IP.
- Protected NSG only allows HTTP/S from the test spoke.
- Route tables send private spoke traffic through the firewall when `deploy_firewall = true`.

### Scenario 3: Key Vault Secrets

Objective: store generated lab access material safely.

Secrets include:

- `windows-admin-password`
- `test-client-private-ip`
- `protected-web-private-ip`
- `protected-web-test-url`
- firewall IPs when deployed
- Entra test user passwords when enabled

### Scenario 4: Entra Test Identity

Objective: create disposable users and groups for identity/security practice.

Users:

- `sec-admin`
- `sec-analyst`
- `lab-user`
- `break-glass`

Groups:

- `security-admins`
- `security-analysts`
- `lab-users`
- `break-glass`

This scenario is disabled by default because it needs directory permissions and a verified domain.

### Scenario 5: Policy Posture

Objective: practice audit-mode governance without breaking the lab.

Policies audit:

- required `environment` tag
- allowed locations
- public IP creation
- storage accounts without HTTPS-only traffic

### Scenario 6: Detection Basics

Objective: inspect security telemetry in Log Analytics.

Included starter query:

```kusto
AzureDiagnostics
| where ResourceProvider == "MICROSOFT.NETWORK"
| where Category in ("AzureFirewallNetworkRule", "AZFWNetworkRule") or Category contains "Firewall"
| where msg_s has "Deny"
| take 50
```

### Scenario 7: SOC Training Platform

Objective: practice a full blue-team workflow with Sentinel incidents, endpoint
telemetry, identity events, workbooks, watchlists, automation, and benign attack
simulation.

Use the SOC profile:

```powershell
terraform plan -var-file="environments/soc.tfvars"
terraform apply -var-file="environments/soc.tfvars"
```

Then follow the [SOC training platform](wiki/scenarios/soc-training-platform.md),
[SOC attack simulation](wiki/runbooks/soc-attack-simulation.md), and
[SOC incident response](wiki/runbooks/soc-incident-response.md) runbooks.

| SOC training platform | `-var-file="environments/soc.tfvars"` | Adds Sentinel content, endpoint telemetry, AD DS, playbooks, and simulations |

## Quick Start

### Prerequisites

- Terraform `>= 1.9.0`
- Azure CLI
- An Azure subscription
- Contributor rights for the subscription or target scope
- Optional: Entra permissions if creating test users or Conditional Access

### 1. Configure Azure

```powershell
az login
az account set --subscription "<subscription-id>"
```

### 2. Configure the lab

Copy the example file:

```powershell
Copy-Item terraform.tfvars.example terraform.tfvars
```

Set your public IP:

```hcl
admin_source_ip_cidr = "YOUR_PUBLIC_IP/32"
```

### 3. Deploy

```powershell
terraform init
terraform plan -var-file="terraform.tfvars"
terraform apply -var-file="terraform.tfvars"
```

### 4. Get access details

```powershell
terraform output test_client
terraform output protected_web
terraform output -raw windows_admin_password
```

The Windows admin password is sensitive. You can also retrieve it from Key Vault when `deploy_keyvault = true`.

### 5. Destroy when done

```powershell
terraform destroy -var-file="terraform.tfvars"
```

## Validated Environment Runs

The default lab and SOC profile have both been applied, tested, and destroyed
from this workspace against the active Azure subscription.

### SOC Profile: July 7, 2026

| Check | Result |
|---|---|
| Toolchain | Terraform `1.12.0`, Azure CLI `2.83.0` |
| Static checks | `terraform fmt -check -recursive` passed; `terraform validate -no-color` passed |
| Profile | `environments/soc.tfvars` |
| Apply | Sentinel, SOC content, AMA endpoint telemetry, AD DS, playbooks, and simulations deployed after fixes |
| Runtime test | Domain controller ready; test and web VMs joined `corp.securitylab.local`; benign simulations ran |
| Telemetry | `AzureDiagnostics`, `WindowsEvent`, and `Heartbeat` records appeared in Log Analytics |
| Sentinel | Analytics rules, watchlists, workbook, automation rules, and Logic App playbook existed; firewall and Key Vault incidents were generated |
| Drift check | Final SOC plan returned detailed exit code `0` before destroy |
| Destroy | `126 destroyed`; all four lab resource groups returned `false`; Terraform state was empty |
| Caveats | `W3CIISLog` ingestion was not validated because the provider rejected the IIS file-log DCR source; Terratest must be run from `tests/` |

See the full [SOC environment test report](wiki/runbooks/soc-environment-test-report-2026-07-07.md)
for exact commands, findings, incidents, and fixes.

### Default Profile: June 7, 2026

| Check | Result |
|---|---|
| Toolchain | Terraform `1.12.0`, Azure CLI `2.83.0` |
| Static checks | `terraform fmt -check -recursive` passed; `terraform validate` passed |
| Plan | Initial Windows plan: `69 to add, 0 to change, 0 to destroy`; recovery plan after the hostname fix: `4 to add, 0 to change, 0 to destroy` |
| Apply | Shared lab resources were created first; recovery apply created the two Windows VMs and Custom Script Extensions |
| Runtime test | Protected IIS active; test client HTTP to protected private IP succeeded; TCP/3389 to protected VM returned `ADMIN_PORT_BLOCKED` |
| Telemetry | Log Analytics showed firewall `Allow` for `test-to-protected-web` and `Deny` for `deny-test-to-protected-admin` |
| Destroy | `69 destroyed`; all four default resource groups returned `false`; generated local state and plan files were removed |

See the full [environment test report](wiki/runbooks/environment-test-report-2026-06-07.md)
for exact commands, findings, and the Log Analytics REST workaround used for
this Azure CLI install.

## GitHub Actions

The repo includes `.github/workflows/terraform-checks.yml` for non-destructive
static checks:

- Terraform formatting
- Terraform backend-free init and validation
- TFLint
- Checkov
- Gitleaks

The workflow runs on pushes to `main`, pull requests, and manual dispatch. It
does not apply or destroy Azure resources.

No Azure credentials are required for the default checks. If you later add a
plan workflow, use GitHub Actions OIDC with Azure and remote Terraform state.

| Variable | Purpose |
|---|---|
| `ARM_CLIENT_ID` | App registration or managed identity client ID for optional Azure OIDC workflows |
| `ARM_TENANT_ID` | Entra tenant ID for optional Azure OIDC workflows |
| `ARM_SUBSCRIPTION_ID` | Azure subscription ID for optional Azure OIDC workflows |
| `DESTROY_CONFIRM` | Recommended explicit guard if a future manual destroy workflow is added |

The current backend is local for easy workstation use. Before shared CI
plan/apply/destroy usage, replace `backend.tf` with an Azure Storage backend so
pipeline state is durable.

## Configuration Options

Important variables:

| Variable | Default | Description |
|---|---:|---|
| `project` | `security` | Naming prefix |
| `environment` | `lab` | Environment label |
| `location` | `westeurope` | Azure region |
| `deploy_firewall` | `true` | Deploy Azure Firewall |
| `firewall_sku_tier` | `Basic` | Firewall SKU |
| `admin_source_ip_cidr` | `0.0.0.0/32` | Allowed RDP source |
| `enable_test_client_public_ip` | `true` | Public RDP path to test client |
| `deploy_bastion` | `false` | Optional private access |
| `deploy_entra_test_users` | `false` | Optional Entra users/groups |
| `deploy_conditional_access` | `false` | Optional report-only MFA policy |
| `deploy_sentinel` | `false` | Optional Sentinel onboarding |
| `deploy_soc_content` | `false` | Optional Sentinel SOC content |
| `deploy_endpoint_telemetry` | `false` | Optional AMA Windows event, Defender operational, and performance telemetry |
| `deploy_identity_domain` | `false` | Optional AD DS identity lab |
| `deploy_sentinel_playbooks` | `false` | Optional Sentinel automation and Logic App |
| `deploy_defender_for_cloud` | `false` | Optional Defender for Cloud server plan |
| `deploy_sentinel_defender_connectors` | `false` | Optional Defender connectors for Sentinel |
| `deploy_keyvault` | `true` | Store generated lab secrets |
| `deploy_log_analytics` | `true` | Enable central logs |

| `deploy_budget` | `true` | Enable budget alert |

## Testing the Lab

### Static Checks

```powershell
terraform fmt -check -recursive
terraform init -backend=false -input=false
terraform validate
```

Before `plan`, `apply`, or `destroy`, initialize the configured local backend:

```powershell
terraform init -input=false
```

Optional tools:

```powershell
tflint --init
tflint --recursive
checkov -d . --framework terraform
gitleaks detect --source . --redact
```

### Terraform Plan

```powershell
terraform plan -var-file="environments/lab.tfvars"
```

For the full SOC profile:

```powershell
terraform plan -var-file="environments/soc.tfvars"
```

Review that:

- Azure Firewall appears only when `deploy_firewall = true`.
- Protected VM has no public IP.
- Test and protected route tables point private spoke traffic at the firewall private IP.
- Entra users are skipped when `deploy_entra_test_users = false`.
- SOC plans include Sentinel content, AMA telemetry, AD DS, and playbooks only
  when the SOC toggles are enabled.

### Manual Connectivity

From the test client:

```powershell
Invoke-WebRequest -UseBasicParsing "http://PROTECTED_PRIVATE_IP"
Test-NetConnection PROTECTED_PRIVATE_IP -Port 3389
```

Expected:

- HTTP succeeds.
- RDP to protected fails.

### Terratest

Integration tests live in `tests/`.

```powershell
cd tests
go test ./...
```

Tests skip automatically when `ARM_SUBSCRIPTION_ID` is not set.

### SOC Evidence

After applying `environments/soc.tfvars`, use:

```powershell
terraform output identity_domain
terraform output soc_content
terraform output endpoint_telemetry
```

Then follow the [SOC attack simulation](wiki/runbooks/soc-attack-simulation.md)
and [SOC incident response](wiki/runbooks/soc-incident-response.md) runbooks.
Validated SOC telemetry includes `AzureDiagnostics`, `WindowsEvent`, and
`Heartbeat`; IIS `W3CIISLog` detection content is included, but file-log
ingestion still needs a supported collection path.

## Security Features

- Private protected workload with no public IP.
- Restricted public RDP to test client via `admin_source_ip_cidr`.
- NSG deny rules for administrative protocols.
- Firewall policy allow and deny examples.
- Key Vault secret storage for generated Windows admin password and lab values.
- Log Analytics diagnostics for firewall and Key Vault.
- Optional SOC profile with AMA endpoint telemetry, AD DS identity events,
  Sentinel detections, workbooks, watchlists, hunting queries, and playbooks.
- Optional Defender for Cloud and Defender XDR connector paths.
- Audit-mode Azure Policy assignments.
- Optional Entra test identity and report-only Conditional Access.
- Optional Sentinel onboarding.
- GitHub Actions validation, linting, secret scanning, and security scanning.

## Cost Estimation

Costs vary by region and usage. The largest default cost is Azure Firewall Basic.

| Resource | Default | Cost behavior |
|---|---:|---|
| Azure Firewall Basic | On | Roughly 0.40 USD/hour in West Europe plus data |
| 2 small Windows VMs | On | Low, but still billable while running |
| Log Analytics | On | Controlled by `log_analytics_daily_quota_gb` |
| Key Vault | On | Usually low for lab usage |
| Bastion | Off | Adds hourly cost when enabled |
| Sentinel | Off | Can add ingestion/analytics cost |
| SOC identity domain | Off | Adds one Windows Server domain controller when `soc.tfvars` is used |
| Defender for Cloud | Off | Can add plan and ingestion costs when licensed toggles are enabled |

Cost tips:

- Destroy the lab after practice.
- Keep `deploy_bastion = false` unless you need private access.
- Keep `deploy_sentinel = false` until you are ready for detection scenarios.
- Use `environments/soc.tfvars` for short SOC training windows, then destroy it.
- Use the budget alert as an early warning, not as a hard cost limit.
- Consider `deploy_firewall = false` when working only on docs, policy, or identity modules.

## Troubleshooting

### Cannot RDP to test client

- Confirm `enable_test_client_public_ip = true`.
- Confirm `admin_source_ip_cidr` is your current public IP with `/32`.
- Confirm the test client public IP from `terraform output test_client`.

### Public RDP breaks after forcing egress

If `force_spoke_egress_to_firewall = true`, public RDP return traffic can become asymmetric. Use Bastion/private access, or keep the default `false`.

### Protected web is not reachable

- Confirm the protected VM private IP from `terraform output protected_web`.
- Confirm route tables exist when `deploy_firewall = true`.
- Confirm firewall rules allow TCP 80/443 from `10.23.0.0/16` to `10.22.0.0/16`.
- Confirm Custom Script Extension completed on the protected VM.

### Entra user creation fails

- Set `deploy_entra_test_users = false` if you do not need identity scenarios.
- Set `entra_domain_name` to a verified tenant domain.
- Confirm the Terraform identity has permission to create users and groups.

### Conditional Access fails

Conditional Access requires Entra ID P1/P2 licensing and the right Graph permissions. It is disabled by default.

### Budget creation fails

Budget APIs can require subscription-level permissions. Set `deploy_budget = false` if your account cannot create budgets.

### SOC domain or telemetry fails

Check the [troubleshooting runbook](wiki/runbooks/troubleshooting.md) for the
domain readiness marker, firewall domain-service rules, AMA `WindowsEvent`
queries, Sentinel playbook permissions, and Defender licensing notes.
