Because of the lack of confidentiality inherent in the '''Layer 2 Networking Protocol''' ('''L2TP''') protocol, '''Internet Protocol Security''' ('''IPsec''') is often used to secure L2TP packets by providing confidentiality, authentication and integrity. The combination of these two protocols is generally known as '''L2TP over IPsec''' (or simply '''L2TP/IPsec'''). | Because of the lack of confidentiality inherent in the '''Layer 2 Networking Protocol''' ('''L2TP''') protocol, '''Internet Protocol Security''' ('''IPsec''') is often used to secure L2TP packets by providing confidentiality, authentication and integrity.
