Implementing VPC Network Security Best Practices

• To make the VPC Network the major focus must be on to minimize attack surface and maximize resource protection.

Least privilege access

Configure least privilege by assigning security groups the minimum inbound and outbound traffic permissions necessary for their specific function. Avoid using “0.0.0.0/0” as a destination address range. use IAM roles to manage access to your VPC resources. Give only the necessary permissions to users and services, following the principle of least privilege. Regularly audit and update IAM roles as personnel and project requirements changes.

Network Segmentation

Use private subnets for resources which does not require internet access. Use NAT gateways for controlled outbound traffic. This technique isolates critical resources. Assign specific IP address ranges to each subnet based on the intended purpose of the resources within, which will help to minimize the attack surface.

Firewall Rules

Create your own firewall rules to control incoming and outgoing traffic to and from your VPC. Use the principle of least privilege, only allowing necessary traffic. Regularly check and update firewall rules as your network grows. Setup monitoring and logging features in the network for better management.

A VPC or Virtual Private Cloud allows you to secure your virtual networking environment including IP addresses, subnets, and network gateways. VPC allows users to create a virtually protected environment for their virtual instances on the Cloud platform and have complete access to the environment. VPC provides users the facility to place and manage necessary resources in a virtual protected environment of the cloud provider like Google Cloud Platform(GCP). We as a user can create, customize, and delete VPC networks in GCP. In this article, we will be exploring how we can create a VPC network in the Google Cloud Platform.
