The Internet Engineering Task Force (IETF)'s IP Security Protocol (IPSec) working group is defining a set of specifications for cryptographically-based authentication, integrity, and confidentiality services at the IP datagram layer. IPSec is intended to be the future standard for secure communications on the Internet, but is already the de facto standard. The IPSec group's results comprise a basis for interoperably secured host-to-host pipes, encapsulated tunnels, and Virtual Private Networks (VPNs), thus providing protection for client protocols residing above the IP layer.

Bit is a binary digit; there is no full form of it.
To test the IPSec policies, use IPSec Monitor. IPSec Monitor (Ipsecmon.exe) provides information about which IPSec policy is active and whether a secure channel between computers is established.
IPSec is a set of IP extensions that provide security services, such as encryption,authentication, and data integrity. IPSec is typically used with a VPN.
There are two modes for IPSec. Transport mode and Tunnel mode. Transport mode is for securing end-to-end communication between two computers and tunnel mode is for securing gateway-to-gateway communication.

To have IPSec VPN two ports are essential - 500 and 50

IPsec Short for IP Security, is a set of protocols developed by the IETF to support secure exchange of packets at the IP layer. IPsec has been deployed widely to implement Virtual Private Networks (VPNs). IPsec supports two encryption modes: Transport and Tunnel. IPsec to work, the sending and receiving devices must share a public key.
IPsec (IP security) is a suite of protocols for securing Internet Protocol (IP) communications by authenticating and/or encrypting each IP packet in a data stream. IPsec also includes protocols for cryptographic key establishment.

IPSEC is a portmanteau of the words 'internet protocol security,' which is a framework of open standards, that allows very secure communication in a network.
