1.1 Administering F-Secure Anti-Virus for Microsoft

Exchange

F-Secure Anti-Virus for Microsoft Exchange can be used either in the

stand-alone mode or in the centrally administered mode, based on your

selections during the installation and the initial setup.

Centralized

Administration

Mode

In the centralized administration mode, you can administer F-Secure

Anti-Virus for Microsoft Exchange with F-Secure Policy Manager.

You can use the F-Secure Anti-Virus for Microsoft Exchange Web

Console to start and stop F-Secure Anti-Virus for Microsoft Exchange,

check its current status and to connect to F-Secure Web Club for support.

In centrally managed installations, F-Secure Anti-Virus for Microsoft

Exchange Web Console cannot be used for configuring the system or

scanning settings, but you can manage the quarantined content with it.

Stand-alone

Mode

You can use F-Secure Anti-Virus for Microsoft Exchange Web Console to

administer the product; monitor the status, modify settings, manage the

quarantine and to start and stop the product if necessary.

CHAPTER 1 13

Using F-Secure Anti-Virus for Microsoft Exchange

1.2 Using Web Console

You can open F-Secure Anti-Virus for Microsoft Exchange Web Console

in any of the following ways:

 Go to Windows Start menu > Programs > F-Secure Anti-Virus for

Microsoft Exchange > F-Secure Anti-Virus for Microsoft

Exchange Web Console

 Enter the address of F-Secure Anti-Virus for Microsoft Exchange

and the port number in your web browser. Note that the protocol

used is https. For example: 

https://127.0.0.1:25023

When the Web Console login page opens, enter your user name and the

password and click Log In. Note that you must have administrator rights

to the host where F-Secure Anti-Virus for Microsoft Exchange Web

Console is installed.

1.2.1 Logging in for the First Time

Before you log in the F-Secure Anti-Virus for Microsoft Exchange Web

Console for the first time, check that javascript and cookies are enabled in

the browser you use.

Microsoft Internet Explorer users:

The address of the F-Secure Anti-Virus for Microsoft Exchange

Web Console, https://127.0.0.1:25023/

, should be added to the

Trusted sites in Internet Explorer Security Options to ensure that

log back in to the F-Secure Anti-Virus for Microsoft Exchange Web

Console.

8. When the login page opens, log in to Web Console with your user

name and the password.

Web Console and select the variables you want to change from the left

pane. For detailed explanations of all variables, see “Administration with

Web Console”, 103.

16

1.2.3 Checking the Product Status

You can check the overall product status on the Home page of F-Secure

Anti-Virus for Microsoft Exchange Web Console. Summary and Services

tabs in the Home page displays an overview of each component status

and most important statistics of the installed F-Secure Anti-Virus for

Microsoft Exchange components. From the Home page you can also

open the product logs and proceed to configure the product components.

1.3 Using F-Secure Policy Manager Console

In the centralized administration mode, you can administer F-Secure

Anti-Virus for Microsoft Exchange with F-Secure Policy Manager. To open

F-Secure Policy Manager Console, select Windows Start menu >

Programs > F-Secure Policy Manager Console.

When the Policy Manager Console opens, go to the Advanced Mode user

interface by selecting View > Advanced Mode.

F-Secure Policy Manager Console is used to create policies for F-Secure

Anti-Virus for Microsoft Exchange installations that are running on

selected hosts or groups of hosts.

For detailed information on installing and using F-Secure Policy Manager

console, see the F-Secure Policy Manager Administrator’s Guide.

1.3.1 Modifying Settings and Viewing Statistics in Centrally

Administered Mode

To change F-Secure Anti-Virus for Microsoft Exchange settings in the

centrally administered mode, follow these instructions:

1. Select F-Secure Anti-Virus for Microsoft Exchange from the

Properties pane.

2. Make sure the Policy tab is selected and assign values to variables

under the Settings branch.

CHAPTER 1 17

Using F-Secure Anti-Virus for Microsoft Exchange

3. Modify settings by assigning new values to the basic leaf node

variables (marked by the leaf icons) shown in the Policy tab of the

Properties pane. For detailed explanations of all variables, see

“F-Secure Anti-Virus for Microsoft Exchange Settings”, 20

Initially, every variable has a default value, which is displayed in gray.

Select the variable from the Properties pane and enter the new value

in the Editor pane to change it. You can either type the new value or

select it from a list box.

Click Clear to revert to the default value or Undo to cancel the most

recent change that has not been distributed.

4. After you have modified settings and cretated a new policy, it must be

distributed to hosts. Choose Distribute from the File menu.

5. After distributing the policy, you have to wait for F-Secure Anti-Virus

for Microsoft Exchange to poll the new policy file. Alternatively, click

Poll the server now in the Server Properties page in F-Secure

Anti-Virus for Microsoft Exchange Web Console.

To view statistics, select the Status tab of the Properties pane. Statistics

are updated periodically and can be reset by choosing Reset Statistics on

the Policy tab of the Properties pane. For more information, see

“F-Secure Anti-Virus for Microsoft Exchange Statistics”, 80.

Settings that are configured during the installation and the

initial setup require that you select the Final check box from the

Product View pane. For more information, see “Changing

Settings That Have Been Modified During Installation or

Upgrade”, 18.

For testing purposes you may also want to change the polling

intervals. To do that, select the domain in F-Secure Policy

Manager console and set the Incoming Packages Polling

Interval and Outgoing Packages Update Interval variables to

30-45 seconds. The variables are located under each of the

two trees in the F-Secure Management Agent / Settings /

Communications branch. Note that since the default polling

interval is 10 minutes, it might take up to 10 minutes for the

new setting to take effect.

18

To manage the quarantined content, use F-Secure Anti-Virus for Microsoft

Exchange Web Console. For more information, see “Quarantine

Management”, 211.

Changing Settings That Have Been Modified During Installation

or Upgrade

If you want to change a setting that has been modified locally during

installation or upgrade, you need to mark the setting as Final in the

restriction editor. The settings descriptions in this manual indicate the

settings for which you need to use the Final restriction. You can also

check in F-Secure Policy Manager Console whether you need to use the

Final restriction for a setting. Do the following:

1. Select the Policy tab and then select the setting you want to check.

2. Select the Status tab to see if the setting has been modified locally.

 If the setting is not shown in grayed font in the Status view, then

the product uses the setting from the base policy and therefore

the Final restriction is not needed.

 If the setting is shown in normal black font, then the setting has

been modified locally. You must mark the setting as Final when

you change it.
