Implementing IPSec Tunnels: Exam Answer
Question
You are designing a connectivity solution between on-premises infrastructure and Amazon VPC.
Your server's on-premises will be communicating with your VPC instances.
You will be establishing IPSec tunnels over the internet.
You will be using VPN gateways and terminating the IPsec tunnels on AWS-supported customer gateways.
Which of the following objectives would you achieve by implementing an IPSec tunnel as outlined above? Choose 4 answers from the options below.

A. B. C. D. E. F.Answer - C, D, E and F.
Option C is correct.
Data that is transmitted through the IPSec tunnel is encrypted.
Option D is correct as it protects data in transit over the internet.
Option E is correct.
Peer identity authentication between VPN gateway and customer gateway is required for implementing VPN IPSec tunnel.
Option F is correct.
Integrity of data transmitted over the internet is also possible via IPSec tunnel.
IPSec is a widely adopted protocol that can be used to provide end-to-end protection for data.
Options A and B are invalid because there is no complete guarantee of fully end-to-end date protection or identity authentication using IPSec.

A. Fully End-to-end protection of data in transit: The IPSec tunnel establishes a secure and encrypted communication channel between the on-premises infrastructure and the VPC instances. This ensures that all data transmitted between these two environments is protected from interception and eavesdropping by third parties.
B. Fully End-to-end Identity authentication: The VPN gateways at both ends of the IPSec tunnel authenticate each other's identities using digital certificates or pre-shared keys. This ensures that only authorized devices can establish the tunnel and communicate over it, providing end-to-end identity authentication.
C. Data encryption across the Internet: The IPSec tunnel encrypts all data transmitted between the on-premises infrastructure and the VPC instances. This ensures that the data cannot be read or tampered with by unauthorized parties while it is in transit over the Internet.
D. Protection of data in transit over the Internet: The IPSec tunnel provides protection against various types of attacks that can compromise the confidentiality and integrity of data in transit over the Internet, such as man-in-the-middle attacks, packet sniffing, and packet injection.
E. Peer identity authentication between VPN gateway and customer gateway: The VPN gateways authenticate each other's identities before establishing the IPSec tunnel. This ensures that only authorized devices can communicate over the tunnel and provides peer identity authentication between the VPN gateway and the customer gateway.
F. Data integrity protection across the Internet: The IPSec tunnel ensures that the data transmitted between the on-premises infrastructure and the VPC instances cannot be tampered with or modified in transit. The data integrity protection is achieved by using cryptographic hash functions to generate message digests, which are then used to verify that the received data is the same as the transmitted data.
In summary, by implementing an IPSec tunnel as outlined above, you can achieve fully end-to-end protection of data in transit, identity authentication, data encryption and integrity protection across the Internet, and peer identity authentication between the VPN gateway and the customer gateway.
