There are many applications which will implement authentication and encryption of network traffic through a separate third party program. However, the Microsoft operating system can also implement this natively through the configuration of IPSEC. In this article we will look at what IPSEC is and a simple example of implementation. What is IPSEC?
Two important protocols for the IPSec protocol suite Authentication (AH) protocol and Encapsulating Security payload (ESP) protocol Purpose of Authentication Header (AH) protocol
The layer IPSec exists at in the OSI model Network layer of the OSI model. The reason why IPSec is transparent at the transport, session, presentation and application layers of the OSI IPSec exists at the network layer of the OSI model. IPSec peer authentication
The only nodes aware of the presence of IPSec are the sender and the receiver, intermediate routers are not aware.
The reason why IPSec is transparent at the transport, session, presentation and application layers of the OSI. IPSec exists at the network layer of the OSI model. IPSec peer authentication. Verification of the identity of a peer computer using preshared keys, public keys, or kerberos protocol with active directory.
A one way cryptographic algorithm that takes an input message of arbitrary length to produce a fixed length digest and uses a secret key.
It encrypts the contents of IP packets.
Verification of the identity of a peer computer using preshared keys, public keys, or kerberos protocol with active directory.
Someone sits between two computers, actively monitoring, capturing and controlling the data transparently.
No, the AH protocol does not encrypt the data.
