What is CHAP primarily used for?

1. User identification and authentication

2. Data encryption and storage

3. Managing web traffic

4. Setting up firewalls

The correct answer is: User identification and authentication

CHAP, or Challenge-Handshake Authentication Protocol, is primarily used for user identification and authentication. It is a widely recognized authentication scheme utilized especially in point-to-point connections. The protocol functions by using a challenge-response mechanism, where the server sends a challenge to the client, and the client must respond with the correct information based on a shared secret, typically a password or cryptographic key. This method ensures that the password is never sent over the network, enhancing security by protecting sensitive information. The underlying goal of CHAP is to verify the identity of users or devices connecting to a network, ensuring that only authorized individuals have access to specific resources. This makes it particularly valuable in environments where secure access is crucial, such as in remote access scenarios. In contrast, the other options focus on different aspects of network and information security. Data encryption and storage relate to methods of securing data, while managing web traffic involves directing or optimizing data flows on the internet or within a private network. Setting up firewalls deals with configuring systems designed to protect networks from unauthorized access, rather than directly authenticating users.
