To handle significant traffic spikes and potentially malicious IPs, you can use Google Cloud Armor to configure rate-based bans. This approach allows you to automatically ban clients that exceed a predefined request rate, protecting your application from potential denial-of-service attacks.

Access Google Cloud Console: Log in to your Google Cloud Console.

Navigate to Google Cloud Armor: Go to the "Security" section and select "Google Cloud Armor".

Create Security Policy: Create a new security policy or edit an existing one. Add a new rule to the policy.

Configure Rate-Based Ban: Set the action to rate_based_ban. Define the rate limit (e.g., requests per second) and set the ban_duration_sec parameter to the desired time interval.

Apply the Policy: Apply the security policy to your backend service or load balancer.

Monitor and Adjust: Monitor the traffic patterns and adjust the rate limits and ban durations as necessary to balance security and availability.

To ensure end-user access is only allowed if the traffic originates from a specific known good CIDR and to utilize GCP's native SYN flood protection, you can use the following product:

VPC Firewall Rules: By configuring VPC firewall rules, you can control traffic to and from your instances based on IP address, protocol, and port. You can set rules to only allow traffic from a specific CIDR block, ensuring that only authorized traffic can reach your application.

Additionally, Google Cloud Platform provides built-in protections against SYN flood attacks, which are a type of DDoS attack. These protections are part of the underlying infrastructure and do not require additional configuration.

Using VPC firewall rules will help you comply with the internal requirement of allowing access only from a specific CIDR and provide the necessary SYN flood DDoS protection.

This PD and bucket data is encrypted using a Google-generated data encryption key (DEK) and key encryption key (KEK). The CMEK feature allows you to create, use, and revoke the key encryption key (KEK). Google still controls the data encryption key (DEK).

A security key is a physical device that you can use for two-step verification, providing an additional layer of security for your Google Account. Security keys can defend against phishing and man-in-the-middle attacks, making your login process more secure.

To prepare for migrating Google Cloud projects to a new organization node, it's crucial to ensure that the projects' current configurations and dependencies are appropriately managed. The two necessary preparation steps are:

Identify inherited Identity and Access Management (IAM) roles on projects to be migrated (C):

Projects inherit IAM roles from their parent resources. Identifying these roles is essential to understand the permissions and access levels that users have on the projects. This will help in ensuring that after migration, the appropriate roles and permissions are applied correctly.

Remove the specific migration projects from any VPC Service Controls perimeters and bridges (E):

VPC Service Controls provide security boundaries around your Google Cloud resources to mitigate data exfiltration risks. Before migrating the projects, they need to be removed from any existing VPC Service Controls perimeters and bridges to prevent any disruption in access or network communication. After migration, the projects can be added back to the necessary perimeters.
