The Internet Protocol Security, or IPsec, framework is a set of protocols designed to add security capabilities to TCP/IP. In this video, learn how IPsec reaches deep into the protocol stack and provides security for the entire payload of encrypted communications. This includes the use of the Encapsulating Security Payload, or ESP, and Authentication Headers, or AH, protocols.
- [Narrator] 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 1970's, 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 everyday…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…
