IPsec (Internet Protocol Security) is a robust protocol suite designed to provide secure, encrypted communication over IP networks. It operates at the network layer and offers comprehensive security services including authentication, integrity, and confidentiality for network communications. IPsec creates a secure tunnel between two network endpoints, encrypting all traffic passing through that tunnel, which makes it an essential technology for virtual private networks (VPNs) and secure remote access.

The protocol works by establishing secure connections through two primary modes: transport mode and tunnel mode. In tunnel mode, which is most commonly used for VPNs, entire IP packets are encapsulated and encrypted, allowing secure transmission across untrusted networks like the public internet. IPsec uses two key protocols - Authentication Header (AH) for packet integrity and Encapsulating Security Payload (ESP) for encryption and authentication.

In the Juniper Security, Associate (JN0-231) exam, IPsec is a critical topic that demonstrates a candidate's understanding of network security fundamentals. The exam syllabus specifically focuses on IPsec VPN concepts, emphasizing practical knowledge of tunnel establishment, traffic processing, and different VPN deployment scenarios.
