## 💡 Feature Explanations

### `Add-Result`

* **Purpose:** Centralizes audit findings
* **Example:**

```powershell
Add-Result "Firewall" "Public profile disabled" "Fail" "High" "Enable firewall"

```

* **Real-Life:** Aggregates all results in JSON/HTML report

### `Check-ASRAndExploitGuard`

* **Purpose:** Checks ASR rules
* **Example:** Detects missing ASR → Risk: High → Action: Enable recommended rules
* **Real-Life:** Prevents ransomware, malware, or malicious script execution

### `Check-MFAAndRemoteAdmin`

* **Purpose:** Ensures MFA for remote/admin accounts
* **Example:** MFA not enforced → Risk: High → Action: Enforce MFA
* **Real-Life:** Prevents stolen credentials attacks

*(Other functions similar logic: Disk scan, EDR, TLS, PowerShell logging…)*

## ⚠️ Caution & Notes

>[!caution]
> * Run **as Administrator** for complete audit
> * Test on non-production systems before deployment
> * Slack/Email notifications require configured credentials/webhooks
> * Some WMI/COM calls may return **“Not Applicable”** if restricted

## 📢 Slack/Teams Integration

* Optional notification to a team channel when audit completes
* Requires webhook URL in `Send-SlackNotification` function

```powershell
Send-SlackNotification -WebhookUrl "https://hooks.slack.com/services/XXX/XXX/XXX"

```
