Comprehensive Web Filtering

Layered Approach: Barracuda multilayered approach to web filtering includes a variety of technologies to regulate web usage and protect against malware. The Barracuda Web Filter gives administrators granular control to manage bandwidth usage, visits to websites, and use of Internet applications to enforce corporate Internet usage policy. Several layers of defense protect against all forms of harmful traffic between internal clients and the Internet, including HTTP, HTTPS, FTP, and application protocols. The measures include: IP-based policy controls, spyware protocol detection and blocking, user authentication, application protocol blocking, URL filtering, user/group-based policy controls, early detection and deep content inspection for virus checking, file type blocking, spyware download blocking, and desktop spyware protection.

Barracuda Central: All Barracuda Networks products are supported by Barracuda Central, a 24×7 advanced security operations center that works continuously to monitor and block the latest Internet threats. Barracuda Central collects email, URLs, and other data from tens of thousands of collection points located in more than 80 countries. In addition, Barracuda Central gets data contributions from more than 150,000 collection points and analyzes the data collected to develop defenses, rules, and signatures to defend your network. As new threats emerge, Barracuda Central is quick to respond to early outbreaks and delivers the latest definitions through Barracuda Energize Updates. These updates require zero administration and ensure that the Barracuda Web Filter provides comprehensive and accurate protection against the latest Internet threats.

Barracuda Central monitors data 24×7 from more than 150,000 Barracuda Networks products in over 80 countries and 17 languages. As new threats emerge, Barracuda Central quickly responds to outbreaks and delivers the latest definitions through automatic Barracuda Energize Updates.

Content Filtering:
Recreational web browsing adversely impacts employee productivity and exposes the network to malware threats. With Barracuda Web Filter, administrators can create policies that control user access to websites using multiple methods, including URL content categories, URL by domain or pattern, and file type blocking. Administrators can choose to block, allow, warn, or monitor access to these domains based on corporate policies.

Application Filtering:

The Barracuda Web Filter provides extremely granular control over Web 2.0 sites and applications, which allows administrators to limit access based on activity type within the same portal. For example, an organization may want to use Facebook or Twitter for viral marketing campaigns but prevent employees from playing games on Facebook or leaking confidential information through Twitter. In addition, administrators can configure the Barracuda Web Filter to archive outbound social media communications, like Facebook posts, tweets, and web-based email, to a message archive solution like the Barracuda Message Archiver. These messages can be searched to comply with HR or litigation requests. This level of functionality allows organizations to provide mission-critical access to Web 2.0 sites while restricting time and bandwidth wasting actions and applications.

Gateway Malware Protection:
The Barracuda Web Application Filter’s spyware protection engine blocks access to blacklisted sites in the extensive, up to date Barracuda Central Database. It also unpacks and examines individual files within 17 different types of archives for viruses and spyware. It can be configured to block password-protected archives that may contain harmful payloads. And, it scans inbound traffic for spyware, adware, trojans, and viruses.

Integrated Desktop Spyware Protection:
From inside the network, the Barracuda Web Filter identifies and blocks communications from infected systems to the Internet. By monitoring traffic at Layer 4, the Barracuda Web Filter detects and blocks outbound spyware activity across all protocols and ports. Once an infected machine is identified, the Barracuda Web Filter intercepts web browsing sessions and presents the user with the Barracuda Spyware Removal Tool in the form of an ActiveX control. The Barracuda Web Filter provides complete security, without the need to install client software on each workstation, by integrating powerful gateway and desktop spyware protection strategies.

Transparent User Authentication:
The Barracuda Web Filter integrates with popular LDAP servers including Microsoft Active Directory, Novell eDirectory, and IBM Lotus Domino Directory. It transparently authenticates workers using their Windows credentials over NTLM or Kerberos when IP-based authentication is not feasible. This is useful in terminal services, Network Address Translation (NAT), or other thin client environments such as Citrix, where multiple clients share one IP address.

Policy Management:
A powerful policy engine supports granular policies by user, group, IP address ranges, or time. The Barracuda Web Filter allows custom creation of allow and block lists, specification of URL patterns, and restriction of Internet downloads based on MIME type, e.g., executables, streaming media, or videos. Administrators can control Internet access from specific client machines or external servers based on source or destination IP address and ports. In addition, exception rules can be created to override global policies and further refine Internet access policy.

SSL Visibility:
The combination of SSL Filtering and SSL Inspection lets customers filter SSL (HTTPS) websites subject to the same filtering rules and policies applied to HTTP traffic. With SSL Filtering, the Barracuda Web Filter monitors Domain Name System (DNS) traffic generated by HTTPS requests and stores an internal database that maps IP addresses to domain names. Using this database, the Barracuda Web Filter can apply policies based on the IP addresses without actually decrypting the traffic to identify domain names. Also, if users require more of granular control, SSL Inspection would decrypt and scan user HTTPS web requests, enabling malware detection and web policy enforcement. It does this by acting as a secure intermediary between user HTTPS web requests and the destination web server (i.e., Facebook, YouTube). After processing, this HTTPS traffic will be re-encrypted on the fly by the Barracuda Web Filter and routed to the destination web server.

Remote Filtering
The Barracuda Web Filter extends protection beyond the network perimeter with the Barracuda Web Security Agent (WSA) and the Barracuda Safe Browser (BSB). The WSA is a tamper-proof client software for off-network Windows and Mac OS X computers, while the BSB is a fully-functional mobile browser for iOS-based devices. In both cases, web traffic from remote clients is filtered through a central Barracuda Web Filter to apply the same web policies to users on and off the network. Both the WSA and the BSB can be centrally configured from the administrator interface. Together, these powerful solutions let organizations implement a consistent web policy across local and distributed workforces without purchasing additional tools.
