SSH & Remote Access: Securely Manage Any Server, Anywhere

SSH (Secure Shell) is the standard protocol for secure remote access to servers and network devices. It provides encrypted communication, authentication, and data transfer capabilities. Every system administrator uses SSH daily to manage servers, transfer files, and create secure tunnels.

• Universal Tool: Used to manage virtually every server worldwide
• Security Foundation: Encrypted, authenticated remote access
• Daily Use: Most-used tool by system administrators
• Cloud Essential: Primary access method for cloud instances

• System Administrators: Master your primary remote access tool
• Developers: Access development and production servers
• DevOps Engineers: Automate with SSH-based tools
• Cloud Engineers: Access and manage cloud instances

• SSH key generation and management
• SSH configuration and hardening
• Port forwarding and tunneling
• SCP and SFTP file transfers
• SSH agent forwarding
• ProxyJump and bastion hosts
• Multiplexing and connection reuse

1. Basics: Connecting, password vs key authentication
2. Key Management: Generation, deployment, agent
3. Configuration: ~/.ssh/config optimization
4. Tunneling: Local, remote, and dynamic forwarding
5. Advanced: Bastion hosts, multiplexing, automation

SSH proficiency is expected in every server administration, DevOps, and cloud engineering role. It is a fundamental skill that enhances productivity in all IT positions.
