    .SYNOPSIS
        Test Advanced Security compliance
    
    .DESCRIPTION
        Runs all compliance tests for Advanced Security hardening and returns
        a comprehensive report of the current security posture.
        
        Tests include:
        - RDP Security (NLA enforcement, SSL/TLS, disable status)
        - WDigest Protection (credential caching disabled)
        - Administrative Shares (disabled and removed)
        - Risky Firewall Ports (LLMNR, NetBIOS, UPnP/SSDP closed)
        - Risky Network Services (SSDPSRV, upnphost, lmhosts stopped)
        - Discovery Protocols (WS-Discovery, mDNS)
    
    .EXAMPLE
        Test-AdvancedSecurity
        Runs all compliance tests and displays results
