"Linux FreeS/WAN is an implementation of IPSEC & IKE for Linux."
"IPSEC is Internet Protocol SECurity. It uses strong cryptography to provide both authentication and encryption services. Authentication ensures that packets are from the right sender and have not been altered in transit. Encryption prevents unauthorised reading of packet contents.
"These services allow you to build secure tunnels through untrusted networks."
