In this video, Ed Liberman demonstrates how to configure and deploy a secure communication strategy using IPsec. IPSec: a framework that provides security on layer three of the OSI model. PPTP: an old VPN protocol that uses PPP and GRE, insecure and should not be used anymore. L2TP: a VPN protocol that tunnels layer two traffic, does not offer any encryption so should be used together with IPsec. Feb 17, 2017 · Go to System Preferences and choose Network. Click on the small “plus” button on the lower-left of the list of networks. In the popup that appears, Set Interface to VPN, set the VPN Type to IKEv2, and give the connection a name. In the Server and Remote ID field, enter the server’s domain name or IP address. Here until, all basic configuration required for an IPSec tunnel is completed. If one of the site has been off line for a while, for example, if Site A has been disconnected, on Site B you need to click Disable and then click Enable after Site A back on line in order to re-establish the IPSec tunnel.
IPSec which works at the network layer is a framework consisting of protocols and algorithms for protecting data through an un-trusted network such as the internet. IPSec provides data security in various ways such as encrypting and authenticating data, protection against masquerading and manipulation. IPSec is a complex framework consisting of many settings, which is why it provides a powerful and flexible set of security features that can be used.
If you want to setup a VPN with IPSec on your Android device, follow this step-by-step guide.

Under Core Infrastructure, go to Networking and click IPSec Connections. A list of the IPSec connections in the compartment that you're viewing is displayed. If you don’t see the one you're looking for, verify that you’re viewing the correct compartment (select from the list on the left side of the page).
Internet Protocol Security (IPSec) Tutorials Table of Contents. Lesson 01 - Internet Protocol Security (IPSec) - What is IPSec? Lesson 02 - Internet Protocol Security (IPSec) - Security Association (SA) Aug 24, 2005 · IPsec is a suite of protocols for securing network connections, but the details and many variations quickly become overwhelming. This is particularly the case when trying to interoperate between disparate systems, causing more than one engineer to just mindlessly turn the knobs when attempting to bring up a new connection. May 15, 2012 · IPSEC is implemented using the Internet Key Exchange (IKE) protocol developed by the Internet Engineering Task Force (IETF) for the mutual authentication and comparison of security parameters between systems or networks connecting to each other. The IPSEC connection process is split into two logical phases. The IPSec packet processing module extracts the “selector” from the packet and looks up the SPD for a policy. If the policy is “discard”, the packet is discarded. If the policy is “pass through”, the forwarding engine forwards the packet normally. If the policy is “IPSec”, the SPD entry should point to an SA in SAD. IPSec provides data confidentiality, data integrity, origin authentication, and anti-replay services. This makes is a popular choice to use across an insecure network, such as the internet. IPSec is independent of specific encryption algorithms.
