Question

Arrange the Site-To-Site IPSec steps below in the correct order:

The destination device decrypts the data and the session key
The sending device encapsulates the encrypted data with new headers
The sending device encrypts the original packet and the session key
The sending device sends the encrypted packet to the destination device.
a) 3, 2, 4, 1
b) 2, 3, 4, 1
c) 3, 1, 2, 4
d) 1, 3, 2, 4

Answer 1

In the context of Site-To-Site IPSec, the proper sequence for data encryption and transmission is to first encrypt the data, encapsulate it with headers, transmit it, and finally, have it decrypted by the recipient.

Step-by-step explanation:

In Site-To-Site IPSec, the correct order of steps involved in encrypting and transmitting data is as follows:

1. The sending device encrypts the original packet and the session key.
2. The sending device encapsulates the encrypted data with new headers.
3. The sending device sends the encrypted packet to the destination device.
4. The destination device decrypts the data and the session key.

Therefore, the correct sequence is option (a) which is 3, 2, 4, 1.
