1.1 Overview

CHAPTER 1 15
Introduction
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 documen t s and distribu te 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 2000/2003 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
Flexible and Scalable
Anti-Virus Protection
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. In addition, it can filter out messages containing keywords that have been defined as disallowed.
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.
F-Secure Anti-Virus for Microsoft Exchange is installed on Microsoft Exchange 2000/2003 Server and it intercepts mail traveling through mailboxes and Public folders. Intercepted attachments and documents are sent to F-Secure Content Scanner Server, which returns disinfected files back to F-Secure Anti-Virus for Microsoft Exchange.
The two-component product architecture ensures that the anti-virus protection does not increase the load on the protected system and that the infected data is never stored on the production network. It also enables you to implement a server pool, so you can share the traffic load between multiple F-Secure Content Scanner Servers and have backup servers if the traffic to primary servers stops for some reason.
Alerting F-Secure Anti-Virus for Microsoft Exchange has extensive alerting
functions, which means that the system administrator can specify a recipient inside the company network to be notified about the infection found in the data content. Of course, the network administrator can be notified about the infection also.
CHAPTER 1 17
Introduction
Powerful and Always
Up-to-date
Virus and Spam
Outbreak Detection
Stand-alone and
Centralized
Administration Modes
F-Secure Anti-Virus for Microsoft Exchange uses the award-winning F-Secure Anti-Virus scanner to ensure the highe st possible detection rate and disinfection capability. The daily F-Secure Anti-Virus signature database updates provide F-Secure Anti-Virus for Microsof t Exchange an always up-to-date protection capability.
F-Secure Anti-Virus scanner consistently r anks at the top when compar ed to competing products. Our team of dedicated virus resea rchers 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 on a daily basis, to make sure our customers are receiving the highest quality service and protection.
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.
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 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,
18
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. With Web Console, you can configure F-Secure Anti-Virus for Microsoft Exchange settings, set up scheduled scans or run manual processes any time you want.
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 and lets you configure the security policies for all F-Secure components. 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.

Installation”, 27.
For very large, performance-critical installations, see
Performance-Critical Installation, 28.
For Microsoft Exchange Cluster Environments, see “Microsoft
Exchange Cluster Environment”, 30.
- DNS (53, UDP/TCP), HTTP (80)
- DNS (53, UDP/TCP), SMTP (25)
- DNS (53, UDP/TCP), 1433 (TCP), only with the dedicated SQL server

2.3.1 Minimum Installation

If the mail traffic is not very heavy, you can install F-Secure Content Scanner Server on the same machine that runs Microsoft Exchange Server. In this case, both F-Secure Content Scanner Server and F-Secure Anti-Virus for Microsoft Exchange will reside on the Microsoft Exchange Server.

You can administer F-Secure Anti-Virus for Microsoft Exchange and F-Secure Content Scanner Server by using the F-Secure Anti-Virus for Microsoft Exchange Web Console.

Alternatively, you can choose to install F-Secure Policy Manager to enable centralized administration of F-Secure Content Scanner Server and F-Secure Anti-Virus for Microsoft Exchan ge.

2.3.2 Medium to Large Installation

If the mail traffic is rather heavy, F-Secure Content Scanner Server should be installed on a dedicated machine. This minimizes the extr a load on the Microsoft Exchange Server.
You should install F-Secure Anti-V irus for Microsoft Exchange in centralized administration mode on each Microsoft Exchange Server.

2.3.3 Performance-Critical Installation

In very large, performance-critical installations you should use multiple F-Secure Content Scanner Server installations. Each F-Secure Content Scanner Server should be installed on a dedicated machine. F-Secure Anti-Virus for Microsoft Exchange can share the virus scanning load between multiple F-Secure Content Scanner Servers.

2.3.4 Microsoft Exchange Cluster Environment

F-Secure Anti-Virus for Microsoft Exchange can be installed on a Windows 2000 Advanced Server or Windows Server 2003 Enterprise Edition cluster. The product supports standard two-node Active-Passive and Active-Active clusters.
Microsoft Exchange need s to be properly configured and running in the cluster before installing F-Secure Anti-Virus for Microsoft Exchange.
F-Secure Anti-Virus for Microsoft Exchange needs to be installed separately on both cluster nodes. When installing in Microsoft Exchange cluster environment, the product must be installed in centrally managed mode, so that you can configure and manage the product with F-Secure Policy Manager. Changing the product settings with F-Secure Anti-Virus for Microsoft Exchange Web Console is not supported in cluster environments, but it can be used for some quarantine management functions.
The settings on both cluster nodes must be identical. To ensure this, place the servers as their own domain in the F-Secure Policy Manager Console and configure all the settings on the domain level, not on th e host level.
It is recommended to install a local F-Secure Content Scanner Server on both cluster nodes. However, if a remote F-Secure Content Scanner Server is used, the dedicated IP address of each cluster node must be visible to the remote F-Secure Content Scanner Server.
When installing the product, the setup program detects Microsoft Exchange Cluster automatically. The setup program also creates a cluster resource for the product automatically. The cluster resource makes it possible to use the product in the cluster, by giving the control of the resource to the cluster service. This and other resources together guarantee that the product works properly in the clu ster in ever y situa tion.
