Full Barracuda support.
While traditional solutions usually detect network threats after they have breached the network by sending log notifications to the administrator, the Barracuda Advanced Threat Protection (ATP) implements full system emulation, providing 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 ATP 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 NextGen Firewall F-Series combines Deep Packet Inspection (DPI) and behavioral traffic analysis to reliably detect and classify thousands of applications and sub-applications, regardless of advanced obfuscation, port hopping techniques, or encryption. It allows the creation of dynamic policies and facilitates establishing and enforcing access and use policies for users and groups by application, application category, location, and time of day. Administrators can now:
The Barracuda NextGen Firewall F-Series 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 F-Series 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.
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. Administrators can thereby gain detailed insight into what a specific application was used for or if a user was trying to circumvent the corporate application usage policy.
In addition to the thousands of applications pre-loaded in Application Control, the Barracuda NextGen Firewall F-Series makes it easy for you to create your own application definitions tailored to your specific needs.To view a complete list of applications and sub-applications that are included under Application Control.
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 NextGen Firewall F-Series are fully user-identity aware by linking a user to one or several IP addresses. Any role assignments that result from identity communicated to the firewall by our health agents can be used within the firewall to facilitate role-based access control (RBAC). F-Series firewalls support authentication of users and enforcement of user-aware firewall rules, web security gateway 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.
The Barracuda NextGen Report Creator is a free tool that allows administrators to collect and consolidate traffic and application usage statistics from multiple Barracuda NextGen Firewall F-Series 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.
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 NextGen Firewall F-Series effectively functions as a generic TCP proxy, forwarding only legitimate TCP traffic to the inside of the network.
Additionally, the F-Series 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 NextGen Firewall F-Series 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.
The Intrusion Detection and Prevention System (IDS/IPS) of the F-Series 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:
Barracuda NextGen Firewall F-Series provides advanced attack and threat protection features such as:
As a result, the Barracuda NextGen Firewall F-Series 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 NextGen Firewall F-Series is constantly up-to-date. If the firewall unit is centrally managed, the updates are conveniently distributed by the Barracuda F-Series Control Centre.
The Malware Protection built into the Barracuda NextGen Firewall F-Series 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 F-Series 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.
A unique combination of next-generation security and adaptive WAN routing technology allows the Barracuda NextGen Firewall F-Series to dynamically assign available bandwidth, uplink, and routing information based not only on protocol, user, location, and content, but also on applications, application categories, and even web content categories. This keeps expensive, highly available lines free for business- and mission-critical applications, while significantly reducing response times and freeing up additional bandwidth.
The integrated revision control system increases auditing ease for the infrastructure and cuts overhead. Additionally, the revision control system for all changes provides compliance with governmental and company policy requirements. Comprehensive reporting makes bandwidth usage and all other security-related information visible, reportable, and easy to read.
Botnet and Spyware Protection guards against botnet infections by blocking access to malicious sites and servers, and detects potentially infected clients based on DNS Sinkholing technology. DNS Sinkholing blocks clients from accessing malicious domains by monitoring outbound DNS requests passing through the firewall. DNS requests to malicious domains are redirected to an internal sinkhole, thereby preventing data exfiltration and identifying the victim. Once an infected client is detected, it can be isolated automatically. An alert can also be created or reported by the Barracuda Report Creator.
