    .SYNOPSIS
        Apply Advanced Security hardening based on selected profile
    
    .DESCRIPTION
        Applies advanced security hardening settings beyond Microsoft Security Baseline.
        
        Features 3 profiles:
        - Balanced: Safe defaults for home users and workstations
        - Enterprise: Conservative approach with domain-safety checks
        - Maximum: Maximum hardening for air-gapped/high-security environments
        
        Features implemented (v2.2.0):
        - RDP NLA enforcement + optional complete disable
        - WDigest credential protection
        - Administrative shares disable (domain-aware)
        - Risky firewall ports closure (LLMNR, NetBIOS, UPnP/SSDP)
        - Risky network services stop
        - Legacy TLS 1.0/1.1 disable
        - WPAD auto-discovery disable
        - PowerShell v2 removal
    
    .PARAMETER SecurityProfile
        Security profile to apply:
        - Balanced: Safe for home users and workstations (default)
        - Enterprise: Safe for corporate environments
        - Maximum: Maximum hardening for air-gapped systems
    
    .PARAMETER DisableRDP
        Completely disable Remote Desktop Protocol (bypasses interactive prompt for Home profile, AirGapped always disables)
    
    .PARAMETER Force
        Force operations that are normally skipped (e.g., admin shares on domain-joined systems)
    
    .PARAMETER WhatIf
        Show what would be changed without actually applying changes
    
    .PARAMETER SkipBackup
        Skip backup creation (NOT RECOMMENDED!)
    
    .PARAMETER DryRun
        Preview changes without applying them (alias for WhatIf)
    
    .EXAMPLE
        Invoke-AdvancedSecurity -SecurityProfile Balanced
        Applies safe hardening for home users
    
    .EXAMPLE
        Invoke-AdvancedSecurity -SecurityProfile Enterprise -WhatIf
        Preview changes for enterprise environment
    
    .EXAMPLE
        Invoke-AdvancedSecurity -SecurityProfile Maximum -DisableRDP -Force
        Maximum hardening with RDP disable for air-gapped system
