Jun 14, 2018 · Internet Protocol Security or IPSec is a network security protocol for authenticating and encrypting the data packets sent over an IPv4 network. IPSec protocol works at layer-3 or OSI model and protects data packets transmitted over a network between two entities such as network to network, host to host, and host to the network.
Five Steps of IPSec Revisited :: Chapter 9: Cisco IOS Five Steps of IPSec Revisited. This section discusses the individual steps required for a successful IPSec data exchange in greater detail. While IPSec incorporates many component technologies and offers multiple encryption options, the basic operation can be broken down into the following five main steps.

NAT-T encapsulates the Quick Mode (IPsec Phase 2) exchange inside UDP 4500 as well. After Quick Mode completes data that gets encrypted on the IPsec Security Association is encapsulated inside UDP port 4500 as well, thus providing a port to be used in the PAT device for translation. To visualize how this works and how the IP packet is encapsulated: Understanding VPN IPSec Tunnel Mode and IPSec Transport This means IPSec wraps the original packet, encrypts it, adds a new IP header and sends it to the other side of the VPN tunnel (IPSec peer). Tunnel mode is most commonly used between gateways (Cisco routers or ASA firewalls), or at an end-station to a gateway, the gateway acting as a … IPSec Support IPSec works by using a symmetric key for validation and encryption. Symmetric key algorithms use the same shared secret key for encoding and decoding data on both sides of the IPSec flow. The Oracle Communications Session Border Controller 's IPSec feature supports the following encryption algorithms: What is IPSEC and how it works – Linux Hint
