IPSec: Internet Protocol Security

IPSec (Internet Protocol Security) is a suite of protocols used to secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPSec includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to use during the session. It provides robust security and is often used in Virtual Private Networks (VPNs).

Key Components of IPSec

Authentication Header (AH): Provides data origin authentication and data integrity protection. It ensures that the packet hasn't been tampered with and confirms the sender's identity.
Encapsulating Security Payload (ESP): Provides confidentiality, data origin authentication, connectionless integrity, anti-replay service, and limited traffic flow confidentiality. ESP can be used alone or in combination with AH.
Security Associations (SAs): A simplex (one-way) connection that affords security services to the traffic carried by it. Security associations are the foundation of IPSec, defining the security parameters and keys used for secure communication.
Internet Key Exchange (IKE): A protocol used to set up a security association (SA) in the IPsec protocol suite. IKE builds upon the Oakley key-exchange protocol and uses X.509 certificates for authentication. There are two versions of IKE: IKEv1 and IKEv2, with IKEv2 being more streamlined and efficient.
