​
Event Information

  • The v1.compute.networks.insert event in GCP for Compute refers to the creation of a new network in the Compute Engine service.
  • This event indicates that a user or an automated process has initiated the creation of a new network within the GCP project.
  • The event can be used to track network creation activities and monitor the overall network infrastructure in GCP Compute Engine.

​
Examples

  • Unauthorized access: If security is impacted with v1.compute.networks.insert in GCP for Compute, it could potentially allow unauthorized users to create new networks, leading to a higher risk of unauthorized access to sensitive resources within the network.
  • Network misconfiguration: The use of v1.compute.networks.insert without proper security controls can result in misconfigured networks, such as incorrect firewall rules or suboptimal routing configurations, which can expose resources to security vulnerabilities.
  • Data exposure: Inadequate security measures while using v1.compute.networks.insert can result in data exposure, where sensitive information within the network is accessible to unauthorized parties, potentially leading to data breaches or privacy violations.

Remediation

​
Using Console

To remediate the issues mentioned in the previous response for GCP Compute using the GCP console, you can follow these step-by-step instructions:

  1. Enable VPC Flow Logs:

    • Go to the GCP Console and navigate to the VPC network page.
    • Select the VPC network where you want to enable flow logs.
    • Click on “Edit” at the top of the page.
    • Scroll down to the “Flow logs” section and click on “Enable flow logs”.
    • Configure the desired flow log settings, such as the filter, destination, and sampling rate.
    • Click on “Save” to enable VPC flow logs for the selected VPC network.

  2. Enable CloudTrail for GCP:

    • Go to the GCP Console and navigate to the CloudTrail page.
    • Click on “Create a new trail” to create a new CloudTrail configuration.
    • Provide a name for the trail and select the GCP project where you want to enable CloudTrail.
    • Choose the desired settings for the trail, such as the storage location, log file validation, and event selectors.
    • Click on “Create” to enable CloudTrail for the selected GCP project.

  3. Enable Security Center for GCP:

    • Go to the GCP Console and navigate to the Security Command Center page.
    • Click on “Enable Security Command Center” to enable Security Center for your GCP project.
    • Follow the on-screen instructions to set up Security Center, including enabling the necessary APIs and granting required permissions.
    • Once Security Center is enabled, you can access the Security Command Center dashboard to view and manage security findings and recommendations for your GCP resources.

Please note that the exact steps and options may vary slightly depending on the specific version of the GCP console and the user’s access permissions.

​
Using CLI

  1. Enable VPC Flow Logs for GCP Compute instances:

    • Use the gcloud compute instances update command to enable VPC Flow Logs for a specific instance: 
      gcloud compute instances update INSTANCE_NAME --enable-network-endpoint-logging

  2. Restrict SSH access to GCP Compute instances:

    • Use the gcloud compute firewall-rules update command to update the firewall rule for SSH access: 
      gcloud compute firewall-rules update FIREWALL_RULE_NAME --source-ranges=IP_RANGE --allow=tcp:22

  3. Implement disk encryption for GCP Compute instances:

    • Use the gcloud compute disks create command to create an encrypted disk: 
      gcloud compute disks create DISK_NAME --size=SIZE --type=DISK_TYPE --encryption-key=KEY_NAME

​
Using Python

To remediate the issues mentioned in the previous response for GCP Compute using Python, you can use the following approaches:

  1. Enforce strong password policies:

    • Use the Google Cloud Identity and Access Management (IAM) API to create a custom password policy for GCP Compute instances.
    • Write a Python script that utilizes the IAM API to enforce password complexity requirements, such as minimum length, special characters, and regular password rotation.

  2. Enable disk encryption:

    • Use the Google Cloud Key Management Service (KMS) API to create and manage encryption keys.
    • Write a Python script that utilizes the KMS API to enable disk encryption for GCP Compute instances. This script can be used to encrypt existing unencrypted disks or to ensure that new disks are automatically encrypted upon creation.

  3. Implement network security groups:

    • Use the Google Cloud Firewall API to create and manage network security groups for GCP Compute instances.

    • Write a Python script that utilizes the Firewall API to define and enforce network access rules, such as allowing only specific IP ranges or protocols to access the instances. This script can be used to create and update firewall rules for Compute instances.
