Understanding IoT and SSH
The Internet of Things (IoT) refers to the network of physical devices connected to the internet, enabling them to collect, share, and analyze data. These devices include everything from home appliances to industrial sensors. SSH, or Secure Shell, is a cryptographic network protocol used for secure data communication, remote command-line login, and command execution.
IoT devices often require remote access for configuration and maintenance, and this is where SSH plays a crucial role. By establishing a secure connection, SSH ensures that data transmitted between the user's device and the IoT device remains confidential and tamper-proof. Understanding the synergy between IoT and SSH is essential for optimizing device management and security.
