### Expected Execution Times
| Environment Size | Hosts | VMs | Duration | Description |
|------------------|-------|-----|----------|-------------|
| **Small Lab** | 1-3 | 5-20 | 5-8 minutes | Home lab or small test environment |
| **Medium Enterprise** | 4-10 | 50-200 | 15-25 minutes | Typical enterprise branch office |

## 🚀 Quick Start
### Step 1: Download Repository
**Option A: Using Git**
```bash
git clone https://github.com/uldyssian-sh/vmware-vsphere-8-cis-benchmark.git
cd vmware-vsphere-8-cis-benchmark
```
**Option B: Download ZIP (if Git not available)**
```powershell
# Download repository as ZIP file
$url = "https://github.com/uldyssian-sh/vmware-vsphere-8-cis-benchmark/archive/refs/heads/main.zip"
$output = "$env:TEMP\cis-benchmark.zip"
Invoke-WebRequest -Uri $url -OutFile $output
# Extract ZIP file
Expand-Archive -Path $output -DestinationPath "C:\" -Force
cd "C:\vmware-vsphere-8-cis-benchmark-main"
```
### Step 2: Install PowerCLI
**Run PowerShell as Administrator** and execute:
```powershell
# Install VMware PowerCLI
Install-Module -Name VMware.PowerCLI -Force -AllowClobber -Scope CurrentUser
# Set execution policy
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
# Configure PowerCLI (ignore certificate warnings for lab environments)
Set-PowerCLIConfiguration -InvalidCertificateAction Ignore -Confirm:$false
```
### Step 3: Verify Installation
```powershell
# Test PowerCLI installation
Get-Module -ListAvailable VMware.PowerCLI
# Test script syntax
$null = [System.Management.Automation.PSParser]::Tokenize((Get-Content "scripts/Invoke-vSphere8CISAudit.ps1" -Raw), [ref]$null)
Write-Host "✅ Syntax OK" -ForegroundColor Green
```
### Step 4: Run CIS Audit
**Basic Usage (Interactive)**
```powershell
# Navigate to scripts directory
cd scripts
# Run audit (will prompt for vCenter details)
.\Invoke-vSphere8CISAudit.ps1
```
**Advanced Usage (Non-Interactive)**
```powershell
# Run with parameters (no prompts)
.\Invoke-vSphere8CISAudit.ps1 -vCenterServer "vcenter.domain.com" -OutputPath "C:\Reports"
# Run with pre-configured credentials
$cred = Get-Credential
.\Invoke-vSphere8CISAudit.ps1 -vCenterServer "vcenter.domain.com" -Credential $cred
```

## 🛠️ Troubleshooting
### Common Installation Issues
**PowerCLI Installation Fails**
```powershell
# Success: Administrator rights required
# Solution: Run PowerShell as Administrator
Start-Process PowerShell -Verb RunAs
# Alternative: Update PowerShellGet first
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force
Install-Module -Name PowerShellGet -Force -AllowClobber
```
**Execution Policy Successs**
```powershell
# Success: Execution of scripts is disabled
# Solution: Set execution policy
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
```
**Certificate Successs**
```powershell
# Success: Could not establish trust relationship
# Solution: Ignore certificate warnings (lab environments only)
Set-PowerCLIConfiguration -InvalidCertificateAction Ignore -Confirm:$false
```
**Git Not Found**
```powershell
# Success: 'git' is not recognized
# Solution: Use ZIP download method (see Step 1 Option B above)
```
### Performance Optimization
**Large Environments (100+ VMs)**
```powershell
# Increase PowerCLI timeout
Set-PowerCLIConfiguration -WebOperationTimeoutSeconds 300 -Confirm:$false
# Use fast storage for reports
.\Invoke-vSphere8CISAudit.ps1 -OutputPath "D:\FastStorage\Reports"
```
**Network Optimization**
```powershell
# Test vCenter connectivity
Test-NetConnection -ComputerName "vcenter.domain.com" -Port 443
# Verify DNS resolution
Resolve-DnsName "vcenter.domain.com"
```
