A security analyst is reviewing a VPN configuration. The VPN uses pre-shared keys for authentication and does not use certificates. The analyst is concerned about the risk of a man-in-the-middle attack. What is the best mitigation?

Replace pre-shared keys with certificate-based authentication

Use a static pre-shared key for all users

Which statement best describes how a proxy server handles client requests?

It forwards requests to the destination server and returns the response to the client

It modifies the client's IP address to match the server's IP address

It stores all client requests in a database for later analysis

It establishes a direct TCP connection between the client and server

What is a potential security risk associated with using an open proxy?

It automatically encrypts all traffic, making it difficult to monitor

It increases the speed of all connections, which can overwhelm the network

It requires users to authenticate, which can lead to credential theft

It can be used by attackers to hide their identity while launching attacks
