What is the purpose of using SSH to connect to a router?

• A. To allow unencrypted access to the router
• B. To provide a secure remote connection to the router command line interface
• C. To manage local connections only
• D. To encrypt only file transfers

Answer: (B)

The purpose of using SSH (Secure Shell) to connect to a router is to provide a secure remote connection to the router command line interface. SSH is designed to secure data as it travels over the network by encrypting the session. This makes it much more difficult for unauthorized users to intercept and understand any transmitted information, such as login credentials or configuration details. In contrast, using unencrypted connections can expose sensitive data to eavesdropping attacks, making remote management insecure. Additionally, while SSH can indeed handle file transfers securely through protocols like SFTP, its primary functionality is to enable safe command line access for administration purposes over potentially insecure networks. This secure approach is essential in protecting network devices against unauthorized access and ensuring that configuration changes and administrative tasks are carried out in a secure manner.
