Cloud NAT GKE
Simplified control of internet access
You don’t necessarily want an application to be accessible to the outside world just because it runs in the cloud. With Google Cloud’s Cloud NAT managed network address translation solution, you can provide your application instances with private IP addresses while still enabling effective and regulated access. to the internet for updates, patching, configuration management, and other purposes. Your Google Cloud VPCs are kept private and safe because no private instance behind the Cloud NAT gateway is directly accessible by outside resources.
Cloud NAT Google
Superior NAT performance
Cloud NAT offers exceptional reliability, performance, and scalability due to its chokepoint-free design, which makes it a software-defined solution without a managed middle proxy.
Fits into all of your workloads
As part of their mission to be the cloud of choice for all workloads at Google Cloud, they built the Cloud NAT service to be compatible with both Google Kubernetes Engine (GKE) and Compute Engine.
Design-wise scalable
A single Cloud NAT gateway may be set up to handle numerous NAT IP addresses and can scale based on the size of your network, eliminating the need for multiple NAT gateways. It is specifically designed for highly scalable application deployments.
High availability in the region
They recognise how critical it is to always have your applications operational. Because of this, they built Cloud NAT with reliability in mind: even in the event of a zone outage, Cloud NAT remains operational throughout the area.
Adaptable IP address distribution
Select the NAT IP allotment that best suits your needs. While auto mode allows the NAT IPs to be allocated and scaled automatically based on the number of instances, manual mode offers you complete control over IP specification.
Features
NAT service management
Provides a network address translation service run by Google Cloud. You may take advantage of network address translation using cloud NAT without having to set up and manage your own NAT gateways.
Adaptable
Supports Google Kubernetes Engine containers as well as Compute Engine virtual machines (VMs).
Every gateway has many NAT IPs
Ability to set up more than one NAT IP address per NAT gateway.
Time-out clocks
Set up timers for NAT timeouts. Timers for controlling network address translation entries are configurable and can be set up via APIs and the Console.
NAT for everyone
Is able to offer NAT for every subnet in a VPC region using a single NAT gateway, regardless of how many instances are present in each subnet.
Elevated accessibility
Regional high availability: the NAT gateway remains accessible even in the event that a zone is inaccessible.
Have you heard about the latest improvements to Cloud NAT? Have you looked into NGFW Enterprise Cloud? They go into both of these subjects in this blog, providing you with anytime access to educational video demonstrations.
NGFWs and cloud NAT
Google Cloud offers distributed cloud-managed network security services called Cloud NGFW and Cloud NAT. When combined, they provide a complete network security solution. Granular control over outgoing traffic is made possible by their integration, which permits or prohibits access based on ports and destination addresses.
This integration for first- and third-party NGFWs is discussed in the video. Additionally, a networking expert has provided a very clear presentation that demonstrates how simple it is to set up and operate in the cloud environment.
Your Google Cloud workloads are protected from both internal and external threats by Cloud Next Generation Firewall, a fully distributed firewall service with powerful security features, micro-segmentation, and widespread coverage.
Benefits of Cloud NGFW include the following:
Distributed firewall service: To support zero-trust security architecture, Cloud NGFW offers a fully distributed, stateful host-based enforcement on every workload.
Cloud NGFW streamlines the deployment and configuration process by implementing network and hierarchical firewall policies that are affixed to resource hierarchy nodes. A uniform firewall experience is offered by these policies throughout the Google Cloud resource hierarchy.
Granular control and micro-segmentation: Across Virtual Private Cloud (VPC) networks and organisations, firewall policies and Tags managed by Identity and Access Management (IAM) work together to give precise control for both east-west and north-south traffic, down to the level of a single virtual machine (VM).
There are several tiers in which Cloud NGFW is accessible:
- Cloud Next-Gen Firewall Requirements
- Next-Generation Cloud Firewall Standard
- Cloud Next Generation Enterprise Firewall
On top of these tiers, Cloud NGFW offers further functionalities that you can install. See Cloud NGFW pricing for further details on the cost of the firewall tiers and other capabilities.
Cloud NGFW Requirements
Google Cloud’s basic firewall solution is called Cloud NGFW Essentials. It has the following attributes and functionalities:
You can organise firewall rules into a policy object that is applicable to all regions or just a subset of them with the help of global and regional network firewall policies.
Your Google Cloud resources can be finely regulated and micro-segmented with the use of IAM-governed Tags and network firewall regulations. Tags are strictly IAM controlled and centrally managed with unique IDs. To enforce stricter and consistent access control throughout your network and regions, you can include references to these Tags in your network firewall policy rules.
A single named logical unit is created by combining many IP addresses and IP ranges into an address group. For entry and egress control, the same address group may be mentioned in several firewall rules.
Network-level traffic is filtered at the network level by VPC firewall rules that make use of service accounts and network tags.
Cloud NGFW Reference
The features of Cloud NGFW Essentials are expanded by Cloud NGFW Standard, giving you more power to defend your cloud infrastructure against harmful assaults.
It has the following characteristics:
Firewall policy rules that contain fully qualified domain name (FQDN) objects block incoming or outgoing traffic to or from particular domains. The IP addresses linked to the domain names are compared to the source or destination of the traffic based on the direction of the traffic.
Firewall policy rules with geolocation objects filter outbound IPv4 and IPv6 traffic according to predefined regions or geographic locations.
You can secure your network by allowing or restricting traffic based on Threat Intelligence data lists by using Threat Intelligence for firewall policy rules.
NGFW Enterprise Cloud
Advanced Layer 7 security features offered by Cloud Next Generation Firewall Enterprise shield your Google Cloud workloads from risks and harmful assaults.
The Cloud Next Generation Firewall Enterprise offers threat detection and protection against malware, spyware, and command-and-control assaults on your network. It also features intrusion prevention service with Transport Layer Security (TLS) interception and decryption.
Extra characteristics
In addition to the Cloud NGFW Essentials and Cloud NGFW Standard levels, Cloud NGFW offers the following features:
Your organization’s firewall policy is created and enforced uniformly via hierarchical firewall policy rules. Hierarchical firewall policies can be applied to specific folders or the entire organisation.
You can confirm whether firewall rules are being used as intended with the help of firewall rules logging.
