Logging In Through SSH
Introduction
Secure Shell (SSH) offers an approach to log into a remote device securely. By providing encryption
and strong authentication, it protects devices against attacks such as IP spoofing and plain text
password interception. The device supports SSH, and you can log in to the device through SSH to
remotely manage and maintain the device, as shown in
