IPSec

The IPSec (IP Security) protocol suite, based on modern cryptographic technologies, provides security services like encryption
and authentication at the IP network layer. It secures the whole network traffic providing guaranteed security for any application
using the network. It can be used to create private secured tunnels between two hosts, two security gateways, or a host and a
security gateway. Up to three tunnels can be active at any given time. Beyond three active tunnels can be saved, but they will
not be active.
IPSec provides encryption and authentication services at the IP level of the protocol stack. IPSec can protect any traffic carried
over IP.
IPSec provides the following services:
●
Authentication only
●
Encryption only
●
Authentication and encryption
Transmitting and receiving data securely over an unprotected network involves deciding on the type of IPSec service, as
mentioned above, required for the connection, establishing a secure connection by a key exchange process and transferring
data using that connection.
The key exchange process is done in one of two ways:
1. Manual Keying where the authentication and encryption keys are provided manually on both sides of the connection.
2. Auto Keying using IKEv2 Protocol where the authentication and encryption keys are generated on either side of the
connection and exchanged by different methods.
