Cisco Secure Firewall Cloud Native
Agile and elastic security at your fingertips
Overview:
The need for on-demand, scalable, and agile security services has grown tremendously with the "work from anywhere" culture and with the need for employees to access corporate applications from their personal devices. Organizations typically build scalable systems by acquiring individual components and then manually automating and orchestrating them with tools from different vendors. This approach creates complexity, making provisioning, management, and troubleshooting of scalable services difficult.
Cisco Secure Firewall Cloud Native provides a platform for deploying scalable and resilient security services using Kubernetes orchestration. It alleviates complexities associated with scalability, load balancing, and service availability. This allows SecOps teams to focus exclusively on security posture management and enforcement.
With Secure Firewall Cloud Native, you have flexibility to choose the performance you need for your organization. It offers agile and elastic security in public and private clouds. Its scalable and feature-rich VPN capability provides secure remote access for employees, partners, and suppliers and protects your workloads against increasingly complex threats with industry-leading security controls.
Product Overview
Secure Firewall Cloud Native provides a common framework to simplify management of security services and a platform that automatically scales and controls them. Customers can choose which services they want to provision, empowering teams with the ability to deploy and scale security based on need.
It uses Kubernetes to provide scalability and resiliency. Customers only need to configure the overall security service. Behind the scenes, Secure Firewall Cloud Native monitors the health and performance of each service, scaling up or down based on user-defined metrics. It customizes configurations for each instance of the service running at any given time, forwarding events and logs to user-configured sinks. Additionally, it offers automatic failure recovery capabilities.
Security policies are managed by Cisco Defense Orchestrator (CDO), a feature-rich software-as-a-service (SaaS) management application with a simple GUI, or using REST APIs. Secure Firewall Cloud Native provides extensive automation capabilities, including options to deploy it as infrastructure as code (IaC).
Secure Firewall Cloud Native is available on Amazon Web Services at release and will roll out on additional platforms soon.
Scalable VPN service using Secure Firewall Cloud Native
To deploy a scalable VPN service, customers deploy Secure Firewall Cloud Native with the included Cloud Native Firewall (CNFW) service.
The three main components that are deployed as part of the CNFW service include:
- Control plane pods: Control plane pods are responsible for configuration of the VPN service. They accept configuration from management applications or from REST APIs. These pods also validate and distribute the configuration to the Enforcement Points.
- Enforcement point pods: Enforcement point pods are responsible for the actual termination of VPN sessions and forwarding of traffic.
- Redirector pods: Redirector pods are responsible for smart load balancing of sessions across enforcement point pods based on real-time assessment of load on each enforcement point pod.
All components are automatically deployed when you install Secure Firewall Cloud Native. It is recommended that customers base their sizing decisions on the number of enforcement point pods they need deployed in the platform. This recommendation is based on expected peak VPN throughput and average VPN throughput. Do not be concerned if your initial estimates are not accurate, as the system is designed for high scalability and elasticity and estimates can always be adjusted with ease.
Resource utilization details for AWS
Each component is optimized to run on a specific type of instance on AWS. The table below lists the instance type details for each component.
| Component | Instance type |
|---|---|
| Control plane pod | m5.xlarge |
| Enforcement point pod | m5.xlarge |
| Redirector pod1 | m5.xlarge |
The installer takes care of deploying each component on the right instance type.
Performance metrics
VPN performance of Secure Firewall Cloud Native is equal to the sum of performance of each enforcement point pod. The system is highly elastic and adds or deletes enforcement point pods dynamically based on current performance requirements. The table below lists tested VPN performance of each enforcement point pod.
| Feature | Performance |
|---|---|
| IPsec VPN throughput (AES 450B UDP test)1 | 1.5 Gbps |
| IPsec VPN peers | 2000 |
| Cisco AnyConnect or clientless VPN user sessions | 2000 |
Based on performance per pod, one can set limits of scaling:
- Minimum number of enforcement point pods: this is the number of pods that are always provisioned.
- Maximum number of enforcement point pods: this is the maximum number of pods that can be provisioned at any point in time.
Secure Firewall Cloud Native monitors the load using specified VPN parameters and makes decisions dynamically to scale the number of pods within the specified range based on load.
Scalability of components
The table below shows the tested scalability limits of each component.
| Attribute | Scale |
|---|---|
| Maximum number of enforcement pods that can be deployed in one instance of Secure Firewall Cloud Native | 75* |
| Maximum number of enforcement pods that can be managed by one control plane pod | 75* |
Licensing for Secure Firewall Cloud Native
Services that run on Secure Firewall Cloud Native are licensed. Each service is licensed using Cisco Smart Licensing, based on the number of CPU cores assigned to the service.
For the CNFW service, customers must have four licenses available in their Cisco Smart Licensing Account for each enforcement point pod that is deployed.
Smart Software Licensing
Cisco Smart Software Licensing makes it easier to buy, deploy, track, and renew Cisco licenses. You will enjoy:
- Simplified purchase and activation of the virtual appliance.
- Easier license management and reporting of virtual appliances due to license pooling.
- utomatic license activation when the virtual appliance is provisioned.
Customers, select partners, and Cisco can view product entitlements and services in the Cisco Smart Software Manager. Configuration and activation are done with a single token. Secure Firewall Cloud Native will self-register with a Cisco server in the cloud, eliminating the need to register products with Product Activation Keys (PAKs). Instead of using PAKs or license files, Smart Software Licensing establishes a pool of software licenses or entitlements that can be used across your business. When a CNFW enforcement point pod is instantiated on a customer's premises, an entitlement for each CPU core is subtracted from the pool. When a licensed CNFW enforcement point pod is decommissioned, or when it is de-instantiated within the Smart Software Manager, its entitlement is added back to your pool.
With the Smart Software Manager, you can manage license deployments throughout your organization easily and quickly. You can also manage multiple products from Cisco that support Smart Software Licensing.
Cisco Secure Firewall Cloud Native uses Smart Software Licensing exclusively.
