Key Features: BYOD (Bring Your Own Device), Secure Remote Access, Network Access Control, Mobile Portal

Features:

Advanced Threat Detection

While traditional solutions usually detect network threats after they have breached the network, by sending log notifications to the administrator, the Barracuda Advanced Threat Detection (ATD) implements full system emulation, which provides deep visibility into malware behavior. Files are checked against a cryptographic hash database that is constantly updated. In case the file is unknown, it is emulated in a virtual sandbox where malicious behavior can be discovered.

The Barracuda ATD offers Administrators granular, file-type-based control including automatic quarantine and blacklisting features to maintain the highest level of protection for an organization's network.

The Barracuda Advanced Threat Detection is an optional subscription.

Application Control 2.0

The Barracuda CloudGen Firewall provides a powerful and extremely reliable detection and classification of more than 1,200 applications and sub-applications by combining Deep Packet Inspection (DPI) and behavioral traffic analysis – no matter if the protocols are using advanced obfuscation, port hopping techniques, or encryption. It allows the creation of dynamic application policies and facilitates establishing and enforcing acceptable access and use policies for users and groups by application, application category, location, and time of day. Administrators can now:

• Block unwanted applications for certain users or groups
• Control and throttle acceptable traffic
• Preserve bandwidth and speed-up business-critical applications to ensure business continuity
• Enable or disable specific application sub-functions (e.g., Facebook Chat, YouTube Postings, or MSN file transfers)
• Intercept SSL-encrypted application traffic

The Barracuda CloudGen Firewall features advanced application-based routing path selection and Quality of Service (QoS) capabilities. These provide additional business value in addition to security by significantly improving network quality and availability, as well as reducing direct line cost due to bandwidth saved.

For rich reporting and drill-down capabilities, the Barracuda CloudGen Firewall comes with real-time and historical application visibility that shows application traffic on the corporate network, thus providing a basis for deciding which connections should be given bandwidth prioritization, crucial for QoS optimization for business-critical applications. Furthermore, it allows adjusting and refining the corporate application use policies.

Deep Application Context

The deep application context analysis allows for deeper inspection of the application data stream by continually evaluating the actual intention of applications and the respective users. By this means administrators can gain detailed insight into what a specific application was used for or if a user was trying to circumvent the corporate application usage policy.

Personalized Application Control

On top of the 1,400+ applications that are delivered out of the box and constantly updated, the Barracuda CloudGen Firewall provides a way to easily create user-defined application definitions for best-in-class application control customized and tailored to an organization's specific needs.

User Identity Awareness

Different network users may need different bandwidth-use rules. Most often, access to certain network resources is limited to certain users or user groups. Preferential allocation of more bandwidth to certain users or user groups and a limitation of available bandwidth for others is a common requirement. It requires the network device to know what user an IP actually belongs to. Barracuda CloudGen Firewalls are fully user-identity aware by linking a user to one or several IP addresses. Any role assignments that result from identity and device posture checks communicated to the firewall by our health agents can be used within the firewall to facilitate role-based access control (RBAC). Barracuda CloudGen Firewalls support authentication of users and enforcement of user-aware firewall rules, web filter settings, and Application Control 2.0 using Active Directory, NTLM, MS CHAP, RADIUS, RSA SecurID, LDAP/LDAPS, TACACS+, as well as authentication with x.509 certificates.

Reporting

The Barracuda NG Report Creator is a free tool that allows administrators to collect and consolidate traffic and application usage statistics from multiple Barracuda CloudGen Firewall units and to create easy-to-read reports in pdf format. Report tasks can be scheduled at various times during the day or week and distributed automatically via email. Besides predefined out-of-the-box reports such as Top Applications, Top Blocked URL Categories and Websites, Top Users by Bandwidth, as well as activity reports for specific users, the reporting engine provides customizable granular reports on user activity, activities during last day/week/month, etc.

For auditing reasons IP addresses can be anonymized.

Intrusion Detection and Prevention

The Barracuda CloudGen Firewall Intrusion Detection and Prevention System (IDS/IPS) strongly enhances network security by providing complete and comprehensive real-time network protection against a broad range of network threats, vulnerabilities, exploits, and exposures in operating systems, applications, and databases preventing network attacks such as:

• SQL injections and arbitrary code executions
• Access control attempts and privilege escalations
• Cross-Site Scripting and buffer overflows
• Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks
• Directory traversal and probing and scanning attempts
• Backdoor attacks, Trojans, rootkits, viruses, worms, and spyware

By providing advanced attack and threat protection features such as stream segmentation and packet anomaly protection, TCP split handshake protection, IP and RPC defragmentation, FTP evasion protection, as well as URL and HTML decoding, the Barracuda CloudGen Firewall is able to identify and block advanced evasion attempts and obfuscation techniques that are used by attackers to circumvent and trick traditional intrusion prevention systems.

As part of the Barracuda Energize Updates subscription, automatic signature updates are delivered on a regular schedule or on an emergency basis to ensure that the Barracuda CloudGen Firewall is constantly up-to-date. If the firewall unit is centrally managed, the pattern updates are conveniently distributed by the Barracuda NextGen Control Center.

Denial of Service (DoS) and Distributed Denial of Service (DDoS) Protection

In today’s world of omnipresent botnets, one of the main tasks of perimeter protection is to ensure ongoing availability of the network for legitimate requests and to detect and repel malicious denial of service attacks. With TCP SYN Flood Protection, the Barracuda CloudGen Firewall effectively functions as a generic TCP proxy, forwarding only legitimate TCP traffic to the inside of the network. Additionally, the Barracuda CloudGen Firewall allows the definition of a rate limit that is applied to the maximum number of sessions per source address to be handled by the firewall. Packets arriving at a rate faster than allowed will simply be dropped. In a massive DDoS attack, the attackers may simply aim for saturating the link by transmitting vast numbers of UDP packets. The integrated environmental monitoring feature of the Barracuda CloudGen Firewall diagnoses such conditions by link and target address monitoring. Once the response of a remote target address to regular ICMP probing fails, the system can be configured to activate different routes and uplinks (for example backup line, ISDN, xDSL). Using this feature, traffic will be unimpeded across unaffected lines and crucial site-to-site and site-to-Internet connectivity remains operational.

Web Filtering

The Barracuda Web Filter enables highly granular, real-time visibility into online activity, broken down by individual users and applications, letting administrators create and enforce effective Internet content and access policies. It protects user productivity, blocks malware downloads and other web-based threats, and enables compliance by blocking access to unwanted websites and servers, providing an important additional layer of security alongside application control.

Malware Protection

Barracuda Malware Protection shields the internal network from malicious content by scanning web content (HTTP and HTTPs), email (SMTP, POP3), and file transfers (FTP) via two fully integrated antivirus engines. Malware protection is based on regular signature updates as well as advanced heuristics to detect malware or other potentially unwanted programs even before signatures are available. Barracuda Malware Protection covers viruses, worms, trojans, malicious java applets, and programs using known exploits on PDF, picture and office documents, macro viruses, and many more, even when using stealth or morphing techniques for obfuscation.

Application-Based Link Selection

The combination of next-generation security and adaptive WAN routing allows the Barracuda CloudGen Firewall to dynamically assign available bandwidth for several links not only based on protocol, user, location, and content, but also based on applications, application categories and web filter categories. This keeps expensive, highly available lines free for business and mission-critical applications, while significantly reducing response times and freeing up additional bandwidth.

Traffic Shaping and Quality of Service

Limited network resources make bandwidth prioritization a necessity. The Barracuda CloudGen Firewall provides strong Quality of Service (QoS) that lets the administrator apply quality aspects and service guarantees to selected traffic flows within the WAN. QoS is often used to prioritize the network traffic of applications that are critical and must not be affected by the network traffic of other applications. The Barracuda CloudGen Firewall provides a large set of QoS techniques, such as traffic shaping, traffic prioritization, and bandwidth partitioning, which assigns a bandwidth limit to certain types of traffic. To select traffic for different priority classes, the available real-time traffic analysis can be used to identify whether network traffic was sent by business-critical applications or by potentially unwanted applications.

Failover and Link Balancing

To ensure the best and most cost-efficient connectivity, the Barracuda CloudGen Firewall provides a wide range of built-in uplink options such as unlimited leased lines, up to four xDSL uplinks, etc. By eliminating the need to purchase additional devices for link balancing, security conscious customers will have access to a WAN connection that never goes down, even if one or two of the existing WAN uplinks are severed. Further, traffic intelligence mechanisms make sure the next defined uplink is activated on the fly and all traffic is rerouted to make full use of the remaining lines. In the event that backup lines provide less bandwidth, intelligent traffic shaping automatically prioritizes business-critical applications, networks, or distinct endpoints.

WAN Optimization

The Barracuda CloudGen Firewall can significantly enhance the WAN performance of distributed network environments by improving availability, performance, and response time of business-critical applications by lowering throughput and transmission delays, affecting time-sensitive decisions and enterprise profitability. The next-generation networking concept of the Barracuda CloudGen Firewall provides a set of powerful features to efficiently reduce and offset the negative effects of high line latencies and response times. By implementing enterprise-grade WAN acceleration features such as data deduplication, traffic compression, and protocol optimization, the Barracuda CloudGen Firewall can significantly improve site-to-site WAN traffic and increase productivity by accelerating the delivery of business applications - at no extra charge. WAN traffic can be effectively compressed up to 95 percent, significantly reducing the bandwidth needed at remote locations while increasing network responsiveness.

Microsoft Azure

Besides VMware, KVM, and XenServer, the Barracuda CloudGen Firewall is fully compatible for use in Windows Azure for establishing site-to-site and/or client-to-site connections to Azure and creating a DMZ in Azure to implement an additional high-security layer.

Barracuda Malware Protection covers viruses, worms, trojans, malicious java applets, and programs using known exploits on PDF, pictures and office documents, macro viruses, and many more, even when using stealth or morphing techniques for obfuscation.

Advanced Threat Detection
Barracuda Advanced Threat Detection (ATD) uses next-generation sandbox technology powered by full-system emulation to catch not only persistent threats and zero-day exploits, but also advanced malware designed to evade detection. Files are forwarded to a cloud-based sandbox environment, where they are executed and analyzed to identify suspicious and malicious behavior.

Barracuda ensures flexible and simple deployment with your existing network infrastructure—no additional hardware is required since resource intensive sandboxing is offloaded to the cloud. The cloud database is continuously updated by all Barracuda CloudGen Firewalls with enabled ATD and, thereby, speed up the processing of already known files.

The administrator has full policy control over how PDF documents, Microsoft Office Files, EXEs/MSIs/DLLs, Android APKs, compressed files and archives are emulated and delivered to the client. Based on identified malware activity, infected users can be automatically quarantined preventing the malware from spreading within the network.

Customizable, on-demand analysis reports for any emulated file provide full insight and details on malicious activities, file behavior, system-registry entries, evasion and obfuscation techniques. This also enables network activities such as establishing encrypted connections to Botnet Command and Control Centers for increased security posture to evade scaled Botnet attacks.

Web Filtering
The web filtering options for the Barracuda CloudGen Firewall options enable highly granular, real-time visibility into online activity, broken down by individual users and applications, letting administrators create and enforce effective Internet content and access policies.

Barracuda CloudGen Firewall features advanced application-based routing path selection and Quality of Service (QoS) capabilities. These provide additional business value in addition to security by significantly improving network quality and availability, as well as reducing direct line cost due to bandwidth saved.

For rich reporting and drill-down capabilities, Barracuda CloudGen Firewall comes with real-time and historical application visibility that shows application traffic on the corporate network, thus providing a basis for deciding which connections should be given bandwidth prioritization, crucial to QoS optimization for business-critical applications. Furthermore, it allows adjusting and refining the corporate application use policies.

Personalized Application Control
On top of the 1,400+ applications that are delivered out of the box and constantly updated, Barracuda CloudGen Firewall provides a way to easily create user-defined application definitions for best-in-class application control customized and tailored to an organization's specific needs.

Application-Based Provider Selection
The combination of next-generation security and adaptive WAN routing allows Barracuda CloudGen Firewall to dynamically assign available bandwidth for several links not only based on protocol, user, location, and content, but also based on applications, application categories, and web filter categories. This keeps expensive, highly available lines free for business and missioncritical applications, while significantly reducing response times and freeing up additional bandwidth.

Deep Application Context
The deep application context analysis allows for deeper inspection of the application data stream by continually evaluating the actual intention of applications and the respective users. By this means administrators can gain detailed insight into what a specific application was used for or if a user was trying to circumvent the corporate application usage policy.

User Identity Awareness & Control
Barracuda CloudGen Firewall supports authentication of users and enforcement of user-aware firewall rules, web filter settings, and application control by seamlessly integrating with

• Microsoft and Citrix terminal service environments
• Microsoft Active Directory
• NTLM
• RADIUS
• RSA SecurID
• LDAP/LDAPS
• TACACS+
• and more...
  
  

Application Risk and Usage Report
The Application Usage and Risk Report is a predefined report type in the Barracuda Report Creator tool providing automated reports and risk analysis based on the network traffic that is traversing the network. It provides an overview on how effective the currently deployed technologies are in detecting and enforcing the corporate application usage policies and gives recommendations what should be taken into account when redefining these policies. For collecting the traffic required for this report, Barracuda offers two different approaches:

• Layer2 Bridging
• SPAN Port / Port Mirroring

In either way, collecting the traffic has no impact on the firewall performance at all. The report creation can be started manually (on-demand) or scheduled (including automated email distribution). And - of course - this report is fully customizable to comply with possible branding requirements.

Cloud Enablement & WAN Virtualization

Today's corporate networks are being transformed by the proliferation of mobile devices and the increasing adoption of SaaS offerings like Microsoft's Office 365 and moving corporate services to private or public clouds.

The net result of this is increased dispersion or fragmentation of corporate network into multiple dislocated segments and a massively increased attack surface. In this scenario a firewall solution is needed that can be deployed to multiple locations on the network with the corresponding next-generation deep inspection features to mitigate attacks. The introduction of, e.g., Office 365 all of a sudden creates a need for direct internet break outs at multiple branch office locations. Thus multiple enforcement points need to be created. Business critical internal traffic running across the WAN links must be protected against outages as well as quality of service impairments due to aggressive but less important network activities on the same physical infrastructure.

Multiple Barracuda CloudGen Firewalls deployed to multiple physical and cloud locations allow an organization to span a highly performant and secure logical application delivery network (ADN) on top of the physical and virtualized infrastructure components. In conjunction with our leading central management concepts both the initial implementation and subsequent life cycle management tasks around the AND can be accomplished a surprisingly low total cost.

The key feature here is that full next-gen deep inspection can be combined with smart policy based adaptive traffic management. Policy based means that applicable QoS settings (bandwidth guarantees, priorities), network path selection, e.g., MPLS vs VPN, and/or privacy requirements can be based on the application or the person/groups causing the traffic. Adaptive means that failover policies can be defined that make sure that in case of unavailability of a particular path available alternative paths can be utilized. This feature allows for improved fault tolerance against outages as well for cost optimization strategies where multiple carriers/ISPs are combined to get the required bandwidth at an optimum price point.

Public cloud offerings like Amazon EC2 and Microsoft Azure are a new and increasingly attractive way to lower cost around IT operations. The business lines profit from a faster-timeto- market, good compute elasticity and an easy option to achieve global service availability quickly. There are challenges too. Replication typical on-premises DC concepts in these environments is impossible without a cloud compatible firewall product.

The Barracuda CloudGen Firewall is ideal for securing and compartmentalizing these public cloud environments – connecting on-premises networks to the cloud and connecting logically separated components within the cloud data centers.

Application-Based Provider Selection
But before an organization can benefit of the cloud, it is mandatory to get to the cloud!

As mentioned earlier, Barracuda CloudGen Firewall includes information on application, application categories, as well as web filter categories into its link selection policy. Such link policies can force for instance business critical traffic to use T1 lines whereas uncritical bulk traffic is routed via less expensive lines.

Traffic Shaping and Quality of Service
Limited network resources make bandwidth prioritization a necessity. Barracuda CloudGen Firewall provides strong Quality of Service (QoS) that lets the administrator apply quality aspects and service guarantees to selected traffic flows within the WAN. QoS is often used to prioritize the network traffic of applications that are critical and must not be affected by the network traffic of other applications. Barracuda CloudGen Firewall provides a large set of QoS techniques, such as traffic shaping, on-the-fly traffic prioritization, and bandwidth partitioning, which assigns a bandwidth limit to certain types of traffic. To select traffic for different priority classes, the available real-time traffic analysis can be used to identify whether network traffic was sent by business-critical applications or by potentially unwanted applications.

Failover and Link Balancing
To ensure the best and most cost-efficient connectivity, Barracuda CloudGen Firewall provides a wide range of built-in uplink options such as unlimited leased lines, up to four uplinks, etc. By eliminating the need to purchase additional devices for link balancing, security conscious customers will have access to a WAN connection that never goes down, even if one or two of the existing WAN uplinks are severed. Further, traffic intelligence mechanisms make sure the next defined uplink is activated on the fly and all traffic is rerouted to make full use of the remaining lines. In the event that backup lines provide less bandwidth, intelligent traffic shaping automatically prioritizes businesscritical applications, networks, or distinct endpoints.

Dynamic Mesh VPN
Simply by defining which deployments may create dynamic site-to-site VPN connections and, thereby, ensure business and communication continuity via low latency VPN connections.

WAN Optimization
Barracuda CloudGen Firewall can significantly enhance the WAN performance of distributed network environments by improving availability, performance, and response time of businesscritical applications by lowering throughput and transmission delays, affecting time-sensitive decisions and enterprise profitability. The next-generation networking concept of Barracuda CloudGen Firewall provides a set of powerful features to efficiently reduce and offset the negative effects of high line latencies and response times.

The Barracuda Network Access Client, when used with a Barracuda NG Firewall, provides centrally managed Network Access Control (NAC) and an advanced personal firewall. This allows enforcement of minimum Windows client security prerequisites before being allowed access to the network or access to a quarantine network. Security posture can be specified according to available Windows patch level, availability of antivirus and/or anti-spyware, and user ID. Access restrictions are enforced locally on the client by the centrally managed personal Windows firewall as well as at the gateway. Using existing Barracuda NG Firewall appliances, Barracuda Networks offers a ready-to-use Network Access Control framework without expensive investments into the basic network infrastructure. All Barracuda Network Access Clients as well as all Barracuda CloudGen Firewall units acting as policy servers can be administered, monitored, and reviewed via the Barracuda NextGen Control Center.

TINA - Barracuda's VPN Protocol
Due to the limitations that come with standard IPsec connections Barracuda Networks created several powerful extensions to standard IPsec tunnel management. This core of the Barracuda NG VPN engine is called TINA (Transport Independent Network Architecture).

The TINA protocol allows to use TCP, UDP, ESP, and IPsec protocols for high speed VPN connections which improves the VPN connectivity substantially by adding:

• Endpoint-to-Endpoint (not network-to-network) connectivity
• NAT friendliness
• Multiple physical transport paths for a logical tunnel
• Multiple tunnels in between two locations
• HTTPS and SOCKS4/5 proxy compatibility
• Dynamic Address Support
• Tunnel heartbeat monitoring

Central Management across the Enterprise

To centralize management across many different firewalls and remote access users, the Barracuda NextGen Control Center enables administrators to manage and configure security, content, traffic management, and network access policies from a single interface. Template-based configuration and globally available security objects enable efficient configuration across thousands of locations.

The Barracuda NextGen Control Center helps significantly reduce the cost associated with security management while providing extra functionality both centrally and locally at the managed gateway. Software patches and version upgrades are centrally controlled from within the management console and deployment can be applied to all managed devices.

Highly customizable administrative roles can be defined to delegate administrative capabilities for specific departments or locations.

Scalable Deployment
Managing the security issues in a widely distributed enterprise network can be painful and extremely time consuming. Managing a system may take only 15 minutes per day. But having 20 firewall systems in place results in five hours per day – just to manage the existing system. With Barracuda NextGen Control Center, managing mulitple Barracuda CloudGen Firewalls takes the same amount of time as managing one.

• Create pre-configured templates for easy-rollout.
• Have all information about the enterprise security deployment available in real time.
• Create reports of either one or all Barracuda CloudGen Firewalls.

Lifecycle Management
Scalable Barracuda CloudGen Firewalls offer companies sustainable investment protection. Energize Updates automatically provide the latest firmware and threat definitions to keep the appliance up to date. With a maintained Instant Replacement subscription, organizations receive a new appliance with the latest specs every four years.
