9 Introduction 1 This guide describes how to configure GroupShield version 5.3 for Lotus Domino on Microsoft Windows using McAfee epolicy Orchestrator versions and 3.0 management software. To use this guide effectively, you need to be familiar with the use of epolicy Orchestrator. For more information, see the epolicy Orchestrator Product Guide. The epolicy Orchestrator software provides a single point of control for all of your McAfee anti-virus products, from which to manage anti-virus policies and view reports of anti-virus events and virus activity in an enterprise environment. Using epolicy Orchestrator, you can configure GroupShield on the target servers across your network; you do not need to configure them individually from the GroupShield Configuration Properties window. This guide includes the following information: Installing GroupShield in the epolicy Orchestrator software repository. See Installing GroupShield in the software repository on page 12. Setting anti-virus policies on the target servers to configure the following GroupShield features: Administration Logging Notification of anti-virus activity and other events On-access scanning On-demand scanning Updating virus-definition (DAT) files Handling encrypted messages VSAPI Alerting Interaction with Alert Manager and epolicy Orchestrator Reports Viewing the GroupShield configuration from a remote server. Configuration Guide 9

10 Introduction NOTE This guide does not provide detailed information about installing or using epolicy Orchestrator software. That information is provided in the epolicy Orchestrator Product Guide. Pre-requisites for using epolicy Orchestrator Before epolicy Orchestrator software can configure GroupShield, the following steps are required: 1 Install GroupShield on a Lotus Domino server. For information about installing GroupShield on the Lotus Domino server, refer to the GroupShield Installation Guide. 2 Install GroupShield software in the epolicy Orchestrator software repository. See Installing GroupShield in the software repository on page Deploy an epolicy Orchestrator agent to the server where GroupShield is installed. Features that you can configure The following GroupShield features can be configured using epolicy Orchestrator. Feature Configuration On-Access scans Mailbox scans Content Scan Rules Configure scanning options, type of files to be scanned, type of action to be performed upon virus detection and blocking of the mail items. Whether to scan Database Reads and/or Database Writes. Apply blocking options: block by extension, filename, subject, number of attachments or file size. Configure scanning options, type of files to be scanned, type of action to be performed upon virus detection and blocking of the mail items. Apply blocking options: block by extension, filename, subject, number of attachments or file size.

Configure scanning options, types of files to scan, and action to perform upon virus detection. Type of Scan - Data Documents and/or Design Documents. Specify an AutoUpdate method (from the Internet, the GroupShield Update Database (GSD53_Update.nsf) or a remote location on your network) for updating the Virus-scanning engine. Configure user detail and path to the source. Specify an update method (from the Internet, the GroupShield Update Database (GSD53_Update.nsf) or a remote location on your network). Configure user detail and path to the source. Features not available through epolicy Orchestrator Some features cannot be implemented using epolicy Orchestrator, and must be accessed directly through GroupShield: View GroupShield's configuration summary page on the target server. However, you can find out about GroupShield's current configuration settings from the Properties tab. View quarantine and log databases from the target GroupShield servers. Execute an on-demand scan from the command line on the target GroupShield server. Install, upgrade, repair or remove GroupShield software on the target GroupShield server. Starting the epolicy Orchestrator console 1 Open the epolicy Orchestrator Console from the Start menu. The console uses standard Microsoft Management Console (MMC) features. 2 To connect to the epolicy Orchestrator server, click the Login icon and enter your user details. After the successful log-on, the console appears with the Console Root highlighted in the console tree. Configuration Guide 11

12 Introduction Installing GroupShield in the software repository What is the software repository? The software repository is the storehouse located on the epolicy Orchestrator server. The repository contains the McAfee anti-virus software products that the epolicy Orchestrator product manages. Software packages must first be placed in the repository before you can configure their anti-virus settings or schedule scans and updates. Adding the GroupShield software to the repository 1 Right-click Repository in the console tree and select Configure Repository from the menu to open the Configure Software Repository dialog box. 2 Select Add new software to be managed. Click Continue. 3 Navigate to the location that contains the file, GSD53.NAP. The file is available on the GroupShield CD within each language sub-folder of the MSI folder. If you are installing from a downloaded copy of GroupShield, it is in the TEMP folder within the system folder of your server. 4 Select the NAP file and click Open. The installation begins. When the files are successfully installed, a message confirms the installation. The console then reflects the new software as a node on the console tree. 5 If you intend to manage Outbreak Manager through epolicy Orchestrator, follow the same procedure, but use the Outbreak NAP file. 12 GroupShield version 5.3 for Lotus Domino on Microsoft Windows

13 Using the property pages to configure and apply policies Figure 1-1. epolicy Orchestrator Console showing GroupShield 5.3 for Lotus Domino installed Using the property pages to configure and apply policies The epolicy Orchestrator interface uses property pages that closely mimic features of the GroupShield interface. The epolicy Orchestrator issues policies to GroupShield servers, but it cannot validate that the requested resources are actually available on the target servers. To validate the requests from epolicy Orchestrator, you must access GroupShield properties using the MMC console on the relevant GroupShield server directly. To configure the settings from a property page: 1 Install GroupShield in the epolicy Orchestrator repository, if you have not already done so. 2 Install the epolicy Agent on the target GroupShield server if you have not already done so. See the epolicy Orchestrator Product Guide for details. 3 Register the GroupShield server with epolicy Orchestrator, if you have not already done so. Configuration Guide 13

14 Introduction 4 Select the GroupShield server or domain, for which you wish to set-up the policy by expanding the Directory sub-tree from the left pane of the epolicy Orchestrator console. Figure 1-2. Console tree directory NOTE To enforce policies successfully, configure epolicy Orchestrator on the physical nodes of the GroupShield server and not the virtual nodes. The Policies, Properties, and Tasks tabs appear in the right pane. 5 Click the Policies tab. 14 GroupShield version 5.3 for Lotus Domino on Microsoft Windows

15 Using the property pages to configure and apply policies 6 In the upper details pane, click next to GroupShield version 5.3 for Lotus Domino on Microsoft Windows to view the policies that can be configured. Figure 1-3. Policies page 7 Click one of the pages On-Access Settings, Mailbox Settings, Alert Settings or Content Scan Rules. The selected property page appears. It may have one or more tabs. For example: Figure 1-4. Typical property page Configuration Guide 15

16 Introduction 8 Deselect Inherit. (Inheritance is described in the epolicy Orchestrator Product Guide.) NOTE If you want to access the fields on this page, ensure that Inherit is deselected. 9 Configure the settings as required, then click Apply. The epolicy Orchestrator agent later collects these settings and applies them to the selected server. To enforce the changes immediately, send an agent wake-up call, which is described in the epolicy Orchestrator Product Guide. NOTE You must click Apply whenever you configure the settings. If you fail to do so your settings will be lost. 16 GroupShield version 5.3 for Lotus Domino on Microsoft Windows

17 Installing the epolicy Orchestrator agent Installing the epolicy Orchestrator agent To install the epolicy Orchestrator agent on the client GroupShield server, you need to establish a two-way trust relationship between the domains of epolicy Orchestrator server and the client GroupShield server. If you do not use full Windows trust relationships in your network, you need to have Full local administrative rights on the client GroupShield server. In other words, the Administrator account must belong to the local administrator group on all client computers. To install the epolicy Orchestrator agent: 1 Log on to the epolicy Orchestrator server. 2 In the console tree under epolicy Orchestrator and Directory, right-click the site or computer. Select Send Agent Install to open the following window. Figure 1-5. Send Agent Install window Configuration Guide 17

18 Introduction 3 To send the agent to the selected site or computer regardless of whether the agent already exists, deselect Only send agent to computers that currently have no agent. NOTE When you install the agent on the target GroupShield server for the first time, this option is not active. 4 Select the Level for this installation. If you are installing the agent on a single computer, Current selection only is already selected. 5 To hide the installation of the agent from the user, select Suppress Agent installation GUI. 6 Enter the Installation path. The default is <system_drive>\epoagent. You can click the arrow to select a recommended path for this field, or you can type a different path for this client. 7 To embed user credentials in the agent installation package, deselect Use epo server credentials, then enter User account and Password. 8 For more information about each field in the Send Agent Install user interface, click Help. Enforcing policies epolicy Orchestrator controls the enforcement of anti-virus policy centrally from the epolicy Orchestrator server by communicating with the agent on each GroupShield server. To examine the activity of the epolicy Orchestrator Agent service on a GroupShield server, go to the GroupShield server, and double-click the epolicy Orchestrator Agent icon or to open the epolicy Orchestrator Agent Monitor window. This window displays a log. Typical messages show how the current properties are collected, current policy is checked, and then enforced. 18 GroupShield version 5.3 for Lotus Domino on Microsoft Windows

New Content Scanning Rule Dialog 2 In the Rule description: section, enter a name in the text box for the new content scan rule. Do not include the string that you are scanning for in the name of the rule. This causes the rule to trigger itself and report upon itself. For example, if you want GroupShield to scan messages for the string Cheap Mortgages, do not call the rule Find_String Cheap Mortgages. 3 In the Options: section define the document areas that the content scan rule checks: Search for attachment named If you select this box, you must enter in the text box the name of the attachment that you want the rule to search for. The rule searches the attachment names of the Lotus Notes documents that it checks. If you want to search for a specific file name extension, specify the extension. You can use wildcard characters (such as *) for attachment name scanning. For example, jp* finds picture.jpg and picture.jpeg. Search in body text and / or and Search in Subject Line Use these checkboxes to define which part of the message you want the content scan rules to search. Configuration Guide 49

50 Setting Up Content Scan Rules If you select Search in body text and / or the rule searches the body text (message area) of the Lotus Notes documents that it checks, searching for the text string specified in the text box called, for the following phrase(s). If you select Search in subject line The rule searches the subject line (heading) of the Lotus Notes documents that it checks, searching for the text string specified in the text box called, for the following phrase(s). NOTE You cannot use wildcard characters when searching for text within body text, as the search will look for the actual characters (either * or? ). You must enter in the for the following phrase(s): text box, the text string that you want the rule to search for. Any of the above If the for the following phrase(s): text box contains multiple text strings (on separate lines in the text box), the content scan rule checks for the existence of any of the text strings in each document. All of the above If the for the following phrase(s): text box contains multiple text strings (on separate lines in the text box), the content scan rule checks for the existence of all of the text strings in each document. If it finds only some of the text strings, the rule does not register a match. NOTE Lotus Domino sometimes stores the file names of attachments within the body text of messages. This can result in a body text search finding the specified word within a file name. 4 Click OK to add the rule to the Defined rules: list. To remove an existing content scan rule: 1 Select the rule that you want to remove. 2 Click Remove. 50 GroupShield version 5.3 for Lotus Domino on Microsoft Windows
