Access to Google Cloud Virtual Machine through SSH
- Establishing a secure remote connection to your virtual machine (VM) instance in Google Cloud Platform (GCP) is a crucial step after provisioning it.
- SSH is a cryptographic network protocol that is the de facto standard for secure remote login and command execution on Unix-like operating systems.
- SSH provides a secure encrypted channel over an unsecured network, preventing potential eavesdropping, packet sniffing or man-in-the-middle attacks that could compromise login credentials or sensitive data.
- Before initiating an SSH connection to a VM instance on GCP, make sure to configure and set up SSH on your local machine.
- The ssh-keygen utility allows generating cryptographic key pairs consisting of a public and private key to establish a secure SSH connection.
- Private keys must always remain secured and never be shared, while public keys are used to access the VM.
- To enable more secure and reliable authentication mechanisms when accessing your VM instance on GCP, disabling password authentication is recommended.
- SSH key pairs provide better audit trails and monitoring capabilities, making them a better option to use rather than passwords to access remote servers.
- Enforcing key-based authentication eliminates the risk of users setting weak or easily-guessable passwords, which is a common vulnerability.
- By enforcing key-based authentication and disabling password logins, one significantly enhances the security of your SSH server and remote access to virtual machines, which aligns to industry practices for secure system administration.
