Event Information

  1. The v1.compute.targetHttpsProxies.insert event in GCP for Compute refers to the creation of a target HTTPS proxy.
  2. This event occurs when a user or an automated process initiates the creation of a target HTTPS proxy in the GCP Compute Engine.
  3. Target HTTPS proxies are used to load balance HTTPS traffic to backend services, allowing secure communication between clients and the services running in the Compute Engine.

​
Examples

  1. Unauthorized access: If security is impacted with v1.compute.targetHttpsProxies.insert in GCP for Compute, it could potentially allow unauthorized users to insert or modify target HTTPS proxies. This could lead to unauthorized access to sensitive data or resources within the GCP environment.

  2. Data breaches: A security impact with v1.compute.targetHttpsProxies.insert in GCP for Compute could result in data breaches. Attackers could exploit vulnerabilities in the target HTTPS proxies, gaining access to sensitive information transmitted over HTTPS connections. This could include personally identifiable information (PII), financial data, or other confidential data.

  3. Service disruption: If security is compromised with v1.compute.targetHttpsProxies.insert in GCP for Compute, it could lead to service disruptions. Attackers could manipulate or disrupt the target HTTPS proxies, causing downtime or degraded performance for applications or services relying on those proxies. This could result in financial losses, reputational damage, and customer dissatisfaction.

Remediation

​
Using Console

  1. Enable VPC Flow Logs:
  • Go to the GCP Console and navigate to the VPC network page.
  • Select the VPC network where the GCP Compute instances are located.
  • Click on “Edit” to modify the VPC network settings.
  • Scroll down to the “Flow logs” section and click on “Enable flow logs”.
  • Configure the flow logs settings, such as the destination bucket and filter criteria.
  • Click on “Save” to enable VPC flow logs for the selected VPC network.
  1. Implement Network Security Groups:
  • Go to the GCP Console and navigate to the VPC network page.
  • Select the VPC network where the GCP Compute instances are located.
  • Click on “Firewall rules” to manage the network security groups.
  • Click on “Create Firewall Rule” to create a new rule.
  • Configure the rule with the appropriate source and destination IP ranges, protocols, and ports.
  • Specify the action to be taken for the traffic matching the rule (allow or deny).
  • Click on “Create” to create the firewall rule.
  1. Enable Cloud Security Command Center:
  • Go to the GCP Console and navigate to the Security Command Center page.
  • Click on “Enable Security Command Center” if it is not already enabled.
  • Once enabled, navigate to the “Findings” page to view the security findings.
  • Review the findings related to the GCP Compute instances and take appropriate actions to remediate them.
  • Follow the recommendations provided by the Security Command Center to address the security issues.
  • Regularly monitor the Security Command Center for new findings and take necessary actions to maintain the security of the GCP Compute instances.

​
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 passwords:

    • Use the Google Cloud Identity and Access Management (IAM) API to create a custom role with the necessary permissions to manage user accounts.
    • Write a Python script that utilizes the IAM API to enforce strong password policies for GCP Compute instances.
    • The script should iterate through all the instances and update the passwords for each user account, ensuring they meet the required complexity criteria.

  2. Enable disk encryption:

    • Use the Google Cloud Key Management Service (KMS) API to create a key ring and a key for encrypting the disks.
    • Write a Python script that utilizes the KMS API to enable disk encryption for GCP Compute instances.
    • The script should iterate through all the instances and enable disk encryption by attaching the appropriate encryption key to each instance’s disks.

  3. Implement network security groups:

    • Use the Google Cloud Firewall API to create network security groups (firewall rules) to restrict inbound and outbound traffic.
    • Write a Python script that utilizes the Firewall API to implement network security groups for GCP Compute instances.
    • The script should define the necessary firewall rules and associate them with the instances, ensuring that only the required ports and protocols are allowed.

Please note that the provided scripts are just high-level examples, and you may need to modify them based on your specific requirements and environment setup.
