SSH, or Secure Shell, is a secure protocol for remotely accessing and managing networked devices, such as servers, routers, and other networked devices. It is designed to provide a secure channel for communication between two systems, such as a client and server, over an insecure network, such as the internet.
The SSH protocol provides a number of security features that help ensure the confidentiality, integrity, and authenticity of data transmitted between the client and server. These security features include:
Encryption: SSH uses encryption to protect the data transmitted between the client and server from being intercepted and read by unauthorized parties.
Authentication: SSH provides strong authentication mechanisms to ensure that the client and server are who they claim to be. This is done using public-key cryptography or password-based authentication.
Integrity: SSH uses digital signatures to ensure that data transmitted between the client and server has not been tampered with or altered during transmission.
SSH is widely used in the IT industry for managing servers and other networked devices, as it provides a secure way to access these systems remotely. It is also used for secure file transfer and other applications where secure communication is required.
