Puppet Server Securing SSH

Securing SSH using Puppet server module. Learn how to write puppet module to secure Linux servers configured as puppet agents. Benefits of learning puppet in Linux administration. How to centrally manage a critical service like ssh using puppet module.

The SSH protocol (also referred to as Secure Shell) is a method for secure remote login from one computer to another. It provides several alternative options for strong authentication, and it protects the communications security and integrity with strong encryption. It is a secure alternative to the non-protected login protocols (such as telnet, rlogin) and insecure file transfer methods (such as FTP).

What Is SSH Protocol Used for?

The protocol is used in corporate networks for:

  1. Providing secure access for users and automated processes
  2. Interactive and automated file transfers
  3. Issuing remote commands
  4. Managing network infrastructure and other mission-critical system components.

How Does SSH Protocol Work?

how ssh worksThe protocol works in the client-server model, which means that the connection is established by the SSH client connecting to the SSH server. The SSH client drives the connection setup process and uses public key cryptography to verify the identity of the SSH server. After the setup phase the SSH protocol uses strong symmetric encryption and hashing algorithms to ensure the privacy and integrity of the data that is exchanged between the client and server.
