Eccouncil Exam ICS-SCADA Topic 2 Question 7 Discussion

Actual exam question for Eccouncil's ICS/SCADA Cyber Security exam
Question #: 7
Topic #: 2
[All ICS/SCADA Cyber Security Questions]

A Virtual Private Network (VPN) requires how many Security Associations?

Show Suggested Answer Hide Answer
Suggested Answer: D

A Virtual Private Network (VPN) typically requires two Security Associations (SAs) for a secure communication session. One SA is used for inbound traffic, and the other for outbound traffic.

In the context of IPsec, which is often used to secure VPN connections, these two SAs facilitate the bidirectional secure exchange of packets in a VPN tunnel.

Each SA uniquely defines how traffic should be securely processed, including the encryption and authentication mechanisms. This ensures that data sent in one direction is handled independently from data sent in the opposite direction, maintaining the integrity and confidentiality of both communication streams.

I'm just hoping the real answer isn't 5 - that would be a total VPN-nightmare!

2 security associations, no doubt about it. Unless you're running a VPN through a lemon, then it's probably 3.

I disagree, I believe the answer is D) 2 because VPN requires two Security Associations for communication.

Hmm, I thought it was 3 but now I'm second-guessing myself. This VPN stuff can get a bit complex.

I'm pretty sure it's 2 security associations, that's the most basic setup for a VPN.
