Question
Which protocol is most commonly used for securing remote
access to network devices?Solution
SSH provides a secure channel over an unsecured network for remote management of devices. Unlike Telnet, which transmits data in plaintext, SSH uses encryption to protect credentials and communication, ensuring confidentiality and integrity. SSH is widely used for securely managing servers, routers, and switches, offering authentication mechanisms and data encryption to prevent eavesdropping or attacks. ________________________________________ Why Other Options Are Incorrect? 1. Telnet: Lacks encryption, making it insecure for modern use. 2. FTP: Used for file transfers, not remote management. 3. SNMP: Designed for network monitoring, not direct device access. 4. ICMP: Used for diagnostics like ping, not device management.
