Securing Remote Access with SSH and Public Key Authentication

SDNTECH: Networking, Cloud, and IoT

In this episode, our hosts explore SSH (Secure Shell), a protocol to establish secure connections between computers. We discuss the importance of SSH in modern networking, where secure remote access and file transfers are crucial. It dives into the fundamental concepts of public key cryptography, including RSA and ECDSA algorithms, and discusses their strengths and weaknesses. It explores how SSH leverages public key pairs for passwordless authentication, providing a more secure alternative to traditional password-based logins. It concludes by explaining how PAM (Pluggable Authentication Modules) can be used for identity access management and authorization, ensuring a more controlled and secure environment.
