What is SSH?
Definition and Functionality
SSH, or Secure Shell, is a cryptographic network protocol designed to provide secure communication over an unsecured network. It allows users to remotely manage and operate network devices securely. SSH encrypts all data transmitted between the client and server, ensuring confidentiality and integrity.
Key Features of SSH
- Encryption: All data is encrypted, preventing unauthorized access.
- Authentication: Users must authenticate themselves before accessing the system.
- Integrity: Ensures that data has not been tampered with during transmission.
SSH is widely used in various industries, from IT and telecommunications to finance and healthcare, to ensure secure communication and data transfer.
