SSCP: Systems Security Certified Practitioner

PPTP transports PPP and can use EAP as a PPP authentication method; Microsoft documents EAP support for PPTP VPN connections, including smart-card technologies. PPTP is not derived from L2TP: the PPTP specification identifies L2TP as a protocol then being defined for PPP tunneling, establishing that L2TP was not PPTP’s source protocol.
