IPSec digitally signs the contents of the entire packet including payload using an Authentication Header thereby providing protection against replay attacks, spoofing, and tampering.

While the authentication header protects data from tampering, it will not stop anyone from seeing it. Encapsulating Security Payload ESP — This protocol encrypts the payload of a data packet and provides authentication, replay proofing, and integrity checking. In this case, data contents IP payload are protected, but anyone looking at the network traffic can see network traffic patterns.

In transport mode, the responsibility to perform any cryptographic operations like encryption etc. In tunnel mode, cryptographic operations like encryption etc. AWS Account. AWS Cloud Watch. AWS GuardDuty. Direct Connect. Tunnel mode is a method of creating Virtual Private Networks. When devices, applications, and network entities exchange data packets, there are opportunities for bad actors to intercept or alter them before they reach their destination.

Hackers can also create fraudulent data packets to pass malware to your devices. An Authentication Header helps the network verify where a packet came from and whether the transmission has been modified.

While Authentication Headers verify the identity of the sender and receiver and detect altered packets, Encapsulating Security Payloads adds encryption and another layer of authentication. In tunnel mode, however, ESP encapsulates the entire data packet and attaches a new header on the outside. While transport mode only secures the data being transmitted, tunnel mode creates an encrypted connection between two network entities.

Other devices on the network remain insecure, as do other applications. IPsec secures all data from all devices in a network and enables them to communicate securely with devices and applications on another network. EMnify is a world-class IoT communication platform.
