12 Defense Layers: Barracuda
Networks multilayered approach to email security provides
the most comprehensive protection available, and optimizes
the processing of each email to maximize performance and
process millions of messages per day. Behind the
industry-leading initiatives of Predictive Sender Profiling
and Barracuda Real-Time Protection are 12 explicit defense
layers including: Denial of Service and Security Protection,
Rate Controls, IP Reputation Analysis, Sender
Authentication, Recipient Verification, Virus Protection,
Policy (user-specified rules), Fingerprint Analysis, Intent
Analysis, Image Analysis, Bayesian Analysis, and a Spam
Rules Scoring engine. Learn More…
Barracuda Reputation and Intent Analysis: While the
standalone value of reputation data is diminishing, it
remains an important baseline for sender profiling. For
reputation analysis, the Barracuda Spam Firewall leverages
data on both the network addresses used to send email as
well as the domain names embedded in the Web links of emails
gathered by Barracuda Central, an advanced technology
operations center where engineers continually monitor the
Internet for trends in spam and virus attacks. Combining
both the IP and reputation data enables Barracuda Networks
to implement countermeasures to mitigate all spam and virus
threats. Learn More…
Predictive Sender Profiling: Relying solely on reputation
analysis is no longer enough to efficiently prevent today’s
sophisticated spam attacks. The industry-leading Predictive
Sender Profiling probes deeper into sent email to identify
bad sender behavior and block identity obfuscation
techniques, despite a sender’s lack of prior spamming
history. As the next generation of anti-spam technology,
Predictive Sender Profiling reinforces the superior 95
percent spam accuracy rate of the Barracuda Spam Firewall.

Barracuda Real-Time Protection: Barracuda Real-Time
Protection is a set of advanced technologies that enables
Barracuda Spam Firewalls to immediately block the latest
virus, spyware, and other malware attacks as they emerge.
These capabilities provide industry-leading response times
to email-borne threats by adding a third layer of antivirus
protection to the Barracuda Spam Firewall.

Triple Layer Antivirus Protection: The Barracuda Spam
Firewall scans all email messages and all incoming files for
viruses using three powerful layers of virus scanning
technology and automatically decompresses archives for
complete virus protection. Barracuda Networks triple-layer
virus blocking includes powerful open source and proprietary
virus definitions and Barracuda Real-Time Protection. Virus
scanning takes precedence over all other mail scanning
techniques, and it is applied even when mail passes through
the connection management layers. As such, even email coming
from “whitelisted” IP addresses or senders, or addressed to
whitelisted recipients, are still scanned for viruses and
blocked if a virus is detected.

Image Spam Protection: Image spam, which generally embeds
text inside images with the intent of hiding content from
traditional spam filters, represents approximately one-third
of all traffic on the Internet. The Barracuda Spam Firewall
was the first major email security product to include image
analysis techniques to effectively protect against new image
spam variants. Learn More…
PDF Spam Protection: In late June 2007, spammers engaged
in new spam campaigns in which they embedded messages within
PDF documents. By using PDF files that require the use of
document viewing applications, such as Adobe Reader,
spammers attempted to bypass text and image scanning engines
in email security products. Because these PDF attacks
utilized existing botnets to generate similar traffic
patterns on the Internet as more traditional spam attacks,
both Barracuda Reputation and Fingerprint Analysis
techniques enabled the Barracuda Spam Firewall to block a
significant portion of PDF spam very early in the message
scanning process. Learn More…
Mail Transport and Policy: The Barracuda Spam Firewall
features a robust Message Transport Agent (MTA) capable of
handling high SMTP connection and mail delivery volumes. For
inbound protection, the MTA includes a number of built-in
protections, including rate controls, IP reputation
analysis, sender authentication, and recipient verification,
which allow rejection of SMTP connections before actually
receiving any messages itself.

Clustering: The Barracuda Spam Firewall supports
clustering of multiple nodes for both redundancy and to
increase total system capacity. For centralized management,
Barracuda Spam Firewalls share configuration and policy
across the cluster, and administrators can change policy or
access any message received across the cluster from any
individual node. For redundancy of quarantine mail storage,
all quarantined messages are stored in at least two nodes in
the cluster – ensuring that messages are always available in
the event that one node becomes unavailable. Barracuda Spam
Firewall clusters can span geographies to facilitate
redundancy across sites. Learn More…
Spyware Protection: The Barracuda Web Filter provides
complete spyware, virus, and malware protection for your
network gateway. The Barracuda Web Filter blocks drive-by
installs or downloads as well as any installation from known
spyware Web sites. It also attacks existing spyware
installations by detecting any spyware access to the
Internet, notifying the administrator and facilitating its
removal through the Barracuda Spyware Removal Tool.

Application Blocking: The Barracuda Web Filter is a
complete content filtering and application blocking solution
designed to enforce acceptable Internet usage policies by
blocking access to objectionable content and unauthorized
Internet applications. Through the ability to easily block
or allow Internet applications, administrators have the
power to better secure the network perimeter, limit
bandwidth usage and eliminate unwanted communications.

flexible content filtering enforcement options for easy
administrative management for organizations that desire to
block, warn or monitor users’ access to inappropriate, high
risk, productivity-inhibiting and/or bandwidth-intensive Web
sites. The Barracuda Web Filter includes an extensive list
of 58 Web site categories that are updated regularly by
Barracuda Central via Barracuda Energize Updates.
