- [Instructor] When the developers of network technology…created the TCP/IP protocol suite, they honestly…didn't pay too much attention to security.…Now, to be fair, when they developed those standards…in the 1970s, security really wasn't an issue.…This has created a dilemma for cyber security professionals…ever since.…We have a set of protocols that we rely upon every day…that were designed without security in mind,…and we now need to retrofit them to add on…security capabilities.…
The internet protocol security, or IPSec framework,…is a set of protocols designed to add security…capabilities to TCP/IP networking.…Unlike TLS, IPSec reaches deep into the protocol stack…and provides security for the entire payload…of encrypted communications.…IPSec uses two protocols to protect information.…The encapsulating security payload, or ESP protocol,…provides both confidentiality and integrity protection…for the payloads of packets.…
The authentication headers, or AH protocol,…uses an integrity check value to provide tamper-proofing…
