5.4.5.IPSEC
“
IPSEC(internet protocol security) is a open standard frame structure to keep the communication security in internet by the
method of encryption.
In computing, Internet Protocol Security (IPsec) is a network protocol suite that authenticates and encrypts the packets of data
sent over a network. IPsec includes protocols for establishing mutual authentication between agents at the beginning of the session
and negotiation of cryptographic keys for use during the session. IPsec can protect data flows between a pair of hosts (host-to-host),
between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). Internet
Protocol security (IPsec) uses cryptographic security services to protect communications over Internet Protocol (IP) networks. IPsec
supports network-level peer authentication, data-origin authentication, data integrity, data confidentiality (encryption), and replay
protection.
IPsec is an end-to-end security scheme operating in the Internet Layer of the Internet Protocol Suite, while some other Internet
security systems in widespread use, such as Transport Layer Security (TLS) and Secure Shell (SSH), operate in the upper layers at the
Transport Layer (TLS) and the Application layer (SSH). Hence, only IPsec protects all application traffic over an IP network. IPsec can
automatically secure applications at the IP layer.
