Which two of the following provide protect against man-in-the-middle attacks? (Choose two.)
Click on the arrows to vote for the correct answerA. B. C. D. E.
The two options that provide protection against man-in-the-middle attacks are IPsec VPNs and Secure Sockets Layer (SSL).
IPsec VPNs provide protection against man-in-the-middle attacks by encrypting all traffic between two endpoints. This means that even if an attacker intercepts the traffic, they will not be able to read it because it is encrypted. Additionally, IPsec VPNs use authentication and key exchange protocols to ensure that only authorized parties can establish a connection.
SSL, also known as Transport Layer Security (TLS), provides protection against man-in-the-middle attacks by encrypting data in transit and providing server authentication. SSL uses a combination of symmetric and asymmetric encryption to secure the connection between the client and the server. When a client connects to a server using SSL, the server sends its SSL certificate to the client. The client then verifies that the certificate is valid and belongs to the intended server. Once the connection is established, all data sent between the client and server is encrypted and protected against interception.
TCP initial sequence number randomization is a technique used to prevent TCP session hijacking, which is a type of attack that allows an attacker to take control of a TCP session between two endpoints. This technique involves randomizing the initial sequence number used in TCP handshakes, which makes it more difficult for an attacker to predict and hijack the session. However, it does not directly protect against man-in-the-middle attacks.
TCP sliding-window checking is a technique used to prevent TCP session hijacking by checking the sequence and acknowledgment numbers in TCP packets to ensure they are valid. This technique can detect and prevent some types of session hijacking attacks, but it does not provide protection against man-in-the-middle attacks.
Network Address Translation (NAT) is a technique used to translate private IP addresses to public IP addresses for communication over the internet. While NAT can provide some level of security by hiding internal IP addresses from the internet, it does not directly protect against man-in-the-middle attacks.
