IPSec
IPSec is basically a way to secure the data transfer between computers. IPSec is making data traffic between two nodes secure by making these things:
- Data Authentication
- Authentication – The packets can be spoofed and not sent from the place they seem they are sent. Data origin authentication can be provided with configuration of IPSec. IPSec will enable us to ensure that received packet from a trusted party is really originating from that party.
- Data integrity – IPSec can be configured to secure that the data packet are not changed when they are crossing the network.
- Anti-replay protection – IPSec is able to check that the packets received are not duplicates of previous data packets.
- Encryption
- IPSec is a technology that enables you to encrypt network data so that it cannot be captured and used by unauthorized persons.
