- Internet Protocol is a best effort,…connectionless protocol, which is used to connect networks…by routing and addressing each packet.…Back in 1998, we see this…Request For Comments: 2401…that provided a framework for what…we know of today as IPsec,…a security architecture for the Internet Protocol.…It has since been updated to RFC 4301, but it has…many of the same beginnings of the original RFC.…
IPsec is a framework for securing IP communications…and is designed to provide security…for IP version 4 and IP version 6.…IPsec can both encypt and authenticate…each IP packet of a session between hosts,…or networks, across the LAN and the internet.…IPsec can protect a much wider…range of applications than SSL,…and no special training is required when using IPsec.…
We can add IPsec to IP version 4…or IP version 6 by using additional headers.…If we take a look at our diagram…on security mechanisms and the TCP/IP stack,…we see that IPsec provides security at the network layer…and can protect the higher-layer protocols.…
