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

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.
