CHAPTER 1 9
Introduction
1.1 Overview
Malicious code, such as computer viruses, is one of the main threats for
companies today. In the past, malicious code spread mainly via disks and
the most common viruses were the ones that infected disk boot sectors.
When users began to use office applications with macro capabilities -
such as Microsoft Office - to write documents and distribute them via mail
and groupware servers, macro viruses started spreading rapidly.
After the millennium, the most common spreading mechanism has been
the e-mail. Today about 90% of viruses arrive via e-mail. E-mails provide
a very fast and efficient way for viruses to spread themselves without any
user intervention and that is why e-mail worm outbreaks, like Sober,
Netsky and Bagle, have caused a lot of damage around the world.
F-Secure Anti-Virus Mail Server and Gateway products are designed to
protect your company's mail and groupware servers and to shield the
company network from any malicious code that travels in HTTP or SMTP
traffic. In addition, they protect your company network against spam. The
protection can be implemented on the gateway level to screen all
incoming and outgoing e-mail (SMTP), web surfing (HTTP and
FTP-over-HTTP) and file transfer (FTP) traffic. Furthermore, it can be
implemented on the mail server level so that it does not only protect
inbound and outbound traffic but also internal mail traffic and public
sources, such as public folders on Microsoft Exchange servers.
Providing the protection already on the gateway level has plenty of
advantages. The protection is easy and fast to set up and install,
compared to rolling out antivirus protection on hundreds or thousands of
workstations. The protection is also invisible to the end users which
ensures that the system cannot be by-passed and makes it easy to
maintain. Of course, protecting the gateway level alone is not enough to
provide a complete antivirus solution; file server and workstation level
protection is needed, also.
Why clean 1000 workstations when you can clean one attachment at the
gateway level?

1.2 How F-Secure Anti-Virus for Microsoft Exchange
Works
F-Secure Anti-Virus for Microsoft Exchange is designed to detect and
disinfect viruses and other malicious code from e-mail transmissions
through Microsoft Exchange Server. Scanning is done in real time as the
mail passes through Microsoft Exchange Server. On-demand scanning of
user mailboxes and public folders is also available.
Scanning
Attachments and
Message Bodies
F-Secure Anti-Virus for Microsoft Exchange scans attachments and
message bodies for malicious code. It can also be instructed to remove
particular attachments according to the file name or the file extension.
If the intercepted mail contains malicious code, F-Secure Anti-Virus for
Microsoft Exchange can be configured to disinfect or drop the content.
Any malicious code found during the scan process can be placed in the
Quarantine, where it can be further examined. Stripped attachments can
also be placed in the Quarantine for further examination.
Flexible and Scalable
Anti-Virus Protection
F-Secure Anti-Virus for Microsoft Exchange is installed on Microsoft
Exchange Server and it intercepts mail traveling to and from mailboxes
and public folders. The messages and documents are scanned with the
scanning component, F-Secure Content Scanner Server, which also
disinfects the infected messages.
Alerting F-Secure Anti-Virus for Microsoft Exchange has extensive alerting
functions, which means that the system administrator can specify a
recipient, such as the network administrator, to be notified about the
infection found in the data content.
Powerful and Always
Up-to-date
F-Secure Anti-Virus for Microsoft Exchange uses the award-winning
F-Secure Anti-Virus techniques and scanning engines to ensure the
highest possible detection rate and disinfection capability. The F-Secure
Anti-Virus definition databases are updated typically multiple times a day
and they provide F-Secure Anti-Virus for Microsoft Exchange an always
up-to-date protection capability.
CHAPTER 1 11
Introduction
F-Secure Anti-Virus scanner consistently ranks at the top when compared
to competing products. Our team of dedicated virus researchers is on call
24-hours a day responding to new and emerging threats. In fact,
F-Secure is one of the only companies to release tested virus definition
updates continuously, to make sure our customers are receiving the
highest quality service and protection.
Virus and Spam
Outbreak Detection
Massive spam and virus outbreaks consist of millions of messages which
share at least one identifiable pattern that can be used to distinguish the
outbreak. Any message that contains one or more of these patterns can
be assumed to be a part of the same spam or virus outbreak.
F-Secure Anti-Virus for Microsoft Exchange can identify these patterns
from the message envelope, headers and body, in any language,
message format and encoding type. It can detect spam messages and
new viruses during the first minutes of the outbreak.
Stand-alone and
Centralized
Administration Modes
F-Secure Anti-Virus for Microsoft Exchange can be installed either in
stand-alone or centrally administered mode. Depending on how it has
been installed, F-Secure Anti-Virus for Microsoft Exchange is managed
either with the F-Secure Anti-Virus for Microsoft Exchange Web Console
or F-Secure Policy Manager.
Scalability and
Reliability
F-Secure Policy Manager provides a scalable way to manage the security
of multiple applications on multiple operating systems, from one central
location. F-Secure Policy Manager is comprised of two components,
F-Secure Policy Manager Console and F-Secure Policy Manager Server,
which are used to administer applications. They are seamlessly
integrated with the F-Secure Management Agents that handle all
management functions on local hosts.
Easy to
Administer
If F-Secure Anti-Virus for Microsoft Exchange is installed in stand-alone
mode it can be managed with the web-based user interface.
If F-Secure Anti-Virus for Microsoft Exchange has been installed in
centrally administered configuration, it is managed with F-Secure Policy
Manager. With its graphical user interface, F-Secure Policy Manager
Console provides a centralized view of the domains and hosts in your
network, lets you configure the security policies for all F-Secure
12
components and set up scheduled scans and run manual scanning
operations. F-Secure Policy Manager receives status information from
F-Secure Anti-Virus for Microsoft Exchange.
F-Secure Policy Manager Server is the server side component that
handles communication between F-Secure Anti-Virus for Microsoft
Exchange and F-Secure Policy Manager Console. It exchanges security
policies, software updates, status information, statistics, alerts, and other
information between F-Secure Policy Manager Console and all managed
systems.
Figure 1-1 (1) E-mail arrives from the Internet to F-Secure Anti-Virus for Microsoft
Exchange, which (2) filters malicious content from mails and attachments, and (3)
delivers cleaned files forward.
