What is SSH and Why It's Important for IoT Devices

SSH, or Secure Shell, is a cryptographic network protocol used for secure data communication, remote command-line login, remote command execution, and other secure network services between two networked computers. In the context of IoT devices, SSH serves as a vital tool for several reasons:

Provides encrypted communication between devices
Enables secure remote access and management
Protects against unauthorized access attempts
Allows for efficient troubleshooting and maintenance

The importance of SSH in IoT device management cannot be overstated. According to a 2022 report by IoT Analytics, over 75% of IoT security breaches occur due to weak or default credentials. SSH addresses this vulnerability by providing strong authentication mechanisms and encrypted communication channels.
