What´s New in Version 7.1.0

Traffic Intelligence SD-WAN Features

SD-WAN is a technology deployed at the edge of the network to connect remote, on-premises, and cloud networks easily and cost effectively to form a Wide Area Network (WAN). SD-WAN provides better application availability by reducing or even eliminating the need for expensive MPLS lines by partially or completely replacing them with multiple cheaper broadband Internet connections. The SD-WAN Traffic Intelligence features enable the NextGen Firewall F to utilize multiple uplinks for encrypted WAN communication and to apply traffic prioritization, compression, and optimization policies. Routing decisions based on the continuously monitored performance of each WAN connection ensures that the traffic is always using the optimal transport based on your business requirements, thereby eliminating the need for manual routing decisions. The following Traffic Intelligence SD-WAN features are available:

  • Dynamic Bandwidth and Latency Detection
  • Performance-Based Transport Selection
  • Adaptive Bandwidth Protection
  • Adaptive Session Balancing

For more information, see Traffic Intelligence.

Dynamic Bandwidth and Latency Detection for Traffic Intelligence

ti_probing.png

Traffic Intelligence has been enhanced by several new features based on Dynamic Bandwidth and Latency Detection. This allows the firewall to determine the actual bandwidth for UDP transports available for a VPN transport through monitoring, active probing, and passive probing.

For more information, see Traffic Intelligence.

Performance-Based Transport Selection for Traffic Intelligence

Performance-Based Transport Selection selects the optimal transport based on the policy selected in the TI settings of the custom connection object. The VPN transport can be selected to optimize for latency, inbound, outbound, or combined bandwidth.

For more information, see Traffic Intelligence  and  How to Configure Performance-Based Transport Selection for VPN Tunnels with Traffic Intelligence.

Adaptive Bandwidth Protection for Traffic Intelligence

Adaptive Bandwidth Protection ensures that traffic in the NoDelay (VoIP) QoS band is always prioritized over standard traffic. The firewall uses the link quality metrics gathered by Dynamic Bandwidth and Latency Detection to adjust traffic shaping to always fully utilize the available bandwidth. It is recommended to combine Adaptive Balancing on the VPN transport with consolidated shaping in order to shape the VPN traffic in a two-step process with Adaptive Shaping on the VPN transport and Consolidated Shaping on the VPN traffic a whole. Adaptive Shaping uses a simplified internal shaping tree that reserves 30% for NoDelay traffic and 70% for standard traffic.

For more information, see Traffic Intelligence and How to Configure Adaptive Bandwidth Protection for VPN Tunnels with Traffic Intelligence.

Adaptive Session Balancing for Traffic Intelligence

Adaptive Session Balancing distributes VPN traffic over multiple transports and uses link-quality metrics collected by Dynamic Bandwidth and Latency Detection for both the initial balancing and to rebalance sessions with a lifetime of over 5 seconds.

For more information, see Traffic Intelligence and How to Configure Session Balancing for VPN Tunnels with Traffic Intelligence.

Traffic Duplication for Traffic Intelligence

Traffic duplication copies packets and simultaneously sends them through the selected primary and secondary transports. Both traffic streams are combined again at the other end of the VPN tunnel. Use Traffic Duplication for applications requiring instant failover without a single dropped packet in case a VPN transport goes down. Since traffic is duplicated, both transports must have the same bandwidth and latency.

For more information, see Traffic Intelligence and How to Configure Traffic Duplication for VPN Tunnels with Traffic Intelligence.

Named Networks

named_networks_01.png

Named Networks provide firewalls with structured network information that usually correlates with the company structure while preserving its human-readable names for users. The usage of Named Networks makes the most sense when they are used in the Global, Range, or Cluster Firewall object in the NextGen Control Center. Named Networks can be used solely for firewall ruleset evaluation, or for both ruleset evaluation and visualization.

For more information, see Named Networks.

Wildcard Network Objects

Wildcard network objects are network objects that include a network mask containing information regarding which parts of the IP address is to be evaluated. Wildcard network objects can be used to describe IP addresses that cannot be covered by network objects using subnets masks.

For more information, see How to Create Wildcard Network Objects.

NextGen Firewall Auto Scaling Cluster in AWS

aws_autoscale_cluster_plain.png

A NextGen Firewall Auto Scaling Cluster scales with demand to create a cost-effective, robust solution for securing and connecting to highly dynamic or cyclical applications running in AWS. The firewall cluster is tightly integrated with AWS services and APIs and can be deployed either to integrate with existing resources in an AWS region, or as part of an auto scaling application. The firewall cluster is highly available and scalable over multiple AWS Availability Zones, without any single point of failure such as additional management or worker node instances.

For more information, see Implementation Guide - NextGen Firewall in AWS and  AWS Reference Architecture - NextGen Firewall Auto Scaling Cluster.

NextGen Firewall Cold Standby Cluster in AWS

cold_standby_01.png

For deployments that require a low-cost solution, the NextGen Firewall Cold Standby Cluster is an auto scaling cluster with a maximum size of one. If the instance fails, it is automatically replaced within minutes. The firewall configuration is securely stored and synchronized through AWS backend services. Replacing the Elastic Load Balancer used in the NextGen Auto Scaling Cluster with a floating Elastic IP allows the use of both TCP- and UDP-based services on the firewall. The default template uses hourly PAYG licensing, but can be modified to use pool licenses for Control Center-managed instances.

Log File Streaming and Custom Metrics for AWS CloudWatch

The NextGen Firewall F can now stream log data to AWS CloudWatch. All selected log files are streamed via syslog streaming to be analyzed in CloudWatch. CloudWatch also collects a set of custom metrics from each firewall instance to be used for reporting and as data points for Auto Scaling policies.

For more information, see How to Configure Log Streaming to AWS CloudWatch.

Log File Streaming to Azure OMS

The NextGen Firewall F can now stream log data to Microsoft OMS in Azure. All selected log files are streamed via syslog streaming to Azure OMS, where they are stored, analyzed, and/or processed.

For more information, see How to Configure Azure OMS Log Streaming.

Web Interface

web_ui.png

Web interface is an alternative configuration management tool to NextGen Admin that enables you to manage the following stand-alone hardware appliances by using a modern web browser: F18, F80, F180, F280, F380, and F400. When using the web interface for firewall configuration management, NextGen Admin can only be used in monitor mode. Switching configuration management to NextGen Admin automatically disables the web interface.

For more information, see Web Interface.

Link Protection for Mail Security in the Firewall

virus_scanning_mail_traffic_atp-01.png.png

Sharing content with other users has become common on the web. As URLs are exchanged using emails, the risk of using incorrectly typed links can lead to fraudulent websites or unknown domains that can harm users. Link Protection protects users from such fraudulent links inside plain-text and HTML emails. In case a URL link is detected inside of an email, the URL link is checked and rewritten in case it is regarded to be fraudulent.

For more information, see Mail Security in the Firewall, and  How to Configure Link Protection for Mail Security in the Firewall.

SSL VPN Access Control Policies

auth_01.png

Access control policies with multi-factor authentication and multi-policy authentication provide granular control over access to resources by qualifying users based on groups they belong to, the technology they use, and how they authenticate.

For more information, see How to Configure Access Control Policies for Multi-Factor and Multi-Policy Authentication.

SSL VPN Google Authenticator Support

auth_02.png

Google Authenticator provides a way of authenticating by using Time-Based One-Time Passwords (TOPT) generated by an app on a mobile device for iOS and Android. On system level, authenticating requires an authentication scheme; on user level, users are required to enroll their device for authentication.

For more information, see How to configure Access Control Policies for Google Authentication and  Enroll your Mobile Device for use Google Authenticator Authentication.

SCADA Protocol Support

In industrial fields, components like sensors and actuators send and receive information as part of industrial processes. The information is transmitted as network data to supervisory control systems for acquisition and management (SCADA). The flow of network data relates to a wide family of protocols, the most common of which are handled by the Barracuda NextGen Firewall.

For more information, see Application Control and  How to Configure Application Rules Matching SCADA Protocols .

SMTP Authentication Support for Email Notifications

Email notifications sent by the Virus Scanner or ATP services can now use SMTP servers with SMTP authentication.

For more information, see How to Configure the System Email Notification Address.

Soft Network Activation for VLANs

Activating changes to the VLAN network configurations is now possible with a soft network activation. Since the network subsystem is not restarted during a soft activation, active connections continue uninterrupted.

For more information, see How to Activate Network Changes.

IPv6 Dynamic WAN Connections

The F-Series Firewall can use both stateless and stateful autoconfiguration with prefix delegation to receive IPv6 addresses from an IPv6 ISP.

For more information, see IPv6.

CudaLaunch 2.3.0

CudaLaunch for iOS now uses the TINA VPN protocol and no longer uses the built-in iOS VPN client. CudaLaunch 2.3.0 also added support for multi-factor authentication.

For more information, see CudaLaunch.

New Hardware Model F82 + F800C

F82_Front.png

F800c-CCC-Front.png

Barracuda released two new appliance models: F82A and F800C. F800 Revision C provides increased port density while F82A model DSLA supports AnnexA (using RJ11 an SFP) and model DSLB supports AnnexB/J (using RJ45 and SFP).
