SSH vs SSL/TLS: Key Differences Explained 🔐

In this video, we’ll break down the differences between SSH and SSL/TLS — two important technologies for securing communication in networking. Whether you’re a beginner or preparing for a certification like CCNA, Security+, or CEH, understanding these protocols is essential.

🔹 SSH (Secure Shell)
Purpose: Used for securely executing commands and managing servers remotely.

Port: Runs on port 22.

Authentication: Uses username and password (or key-based authentication) to establish a secure connection.

Technology Base: Works on network tunnels to encrypt and secure traffic.

Category: A remote protocol designed for server administration.

Goal: Reduce security threats during remote logins, such as password interception.

🔹 SSL/TLS (Secure Socket Layer / Transport Layer Security)
Purpose: Secures the communication between a server and a browser (or any client).

Port: Runs on port 443 (HTTPS).

Authentication: Uses X.509 digital certificates for server and client authentication.

Technology Base: Based on digital certificates for trust and encryption.

Category: A security protocol for protecting web traffic and personal data.

Goal: Ensure safe data transfer over the internet — preventing eavesdropping and tampering.


💡 In Simple Terms:
SSH is like a secure remote control for servers.

SSL/TLS is like a secure envelope for sending web data.
