Which protocol would be used to provide security for employees that access systems remotely from home?Question 48Select one:SCPSSHWPATelnet

Step 1: Break Down the Problem

To determine which protocol provides security for remote access, we will evaluate the options given: SCP, SSH, WPA, and Telnet.

Step 2: Relevant Concepts

1. SCP (Secure Copy Protocol): Used for secure file transfer over a network.
2. SSH (Secure Shell): A protocol used to securely access and manage devices over a network.
3. WPA (Wi-Fi Protected Access): A security protocol for wireless networks, not specifically for remote access to systems.
4. Telnet: An unencrypted protocol used for remote access, which does not provide security.

Step 3: Analysis and Detail

• SCP operates over SSH and does secure file transfers, but it does not provide a comprehensive remote access solution.
• SSH provides encrypted communication and secure access to remote systems, making it suitable for employees needing secure connections from home.
• WPA secures wireless communication but is not relevant to remote system access.
• Telnet is insecure since it does not encrypt communications, making it vulnerable to interception.

Step 4: Verify and Summarize

Among the protocols evaluated, SSH stands out as the best choice for providing secure remote access for employees. SCP, while also secure, is more focused on file transfer. WPA deals with wireless security. Telnet should not be used due to its lack of security.

Final Answer

SSH (Secure Shell) is the correct protocol to provide security for employees accessing systems remotely from home.
