GCP Security Overview

Access to an GCP cloud instance can be controlled by 

• an external firewall,
• the operating system firewall of the instance,
• GCP ????

Connecting to the Cloud Instance

During the configuration of your instance you should have created a security group allowing at the minimum SSH access to the instance. If this has been done correctly, you can, for example, use SSH from the command-line or from a tool such as PuTTY to access the command-line of the user sshuser on the Charon-SSP instance.

Please note: the file permissions of the private key file must be set such that the file is only readable by the user (e.g., # chmod 400 <private-key-file>).

There are several ways to connect to your Charon-SSP cloud instance using this basic SSH protocol access. Some of them are described in the following sections below.
