Network Security Question in Checkpoint Firewall IPSec VPN and Encryption Method

Network Security Question in Checkpoint Firewall

Lecture 2 IPSec VPN and Encryption Method:
1. What is Authenticity, Confidentiality and Integrity? 

Authenticity: Verifies that the packet received is actually from the claimed sender. It verifies the authenticity of sender. Pre-shared Key, Digital Certificate are some methods that can be used for authentication. 

Confidentiality:Encrypts the message content through encryption so that data is not disclosed to unauthorized parties. Encryption algorithms include 

DES (Data Encryption Standard), 3DES (Triple-DES), AES (Advanced Encryption Standard)

Integrity: Ensure that the contents of the packet have not been altered in between by man-in-middle. Hash algorithm includes MD5, SHA.

2. What is Symmetric and Asymmetric Encryption?

Symmetric Encryption:  In symmetric encryption, a single key is used both to encrypt and decrypt traffic. It is also referred as shared key of shared secret encryption. Symmetric encryption algorithms include DES, 3DES, AE…
