4 4 Desktop Internet Security s Desktop Requirements for Running Centricity Business Web Applications Following are desktop requirements for Centricity Business 4.3 and later: Display requirements: A 1024x768 or larger display area On Windows XP and Windows 7, the Windows Classic Theme and Windows XP Theme (Styles) are supported. 256 or more colors Microsoft Internet Explorer 6.0 SP1 or higher; the highest version currently supported is 8.0. Microsoft.NET Common Language Runtime (CLR) version 2.0 (higher versions may be used; consult the appropriate System Environment Specifications document for details).

5 Desktop Internet Security s 5 Internet Security s for Running Centricity Business Web Applications on the Desktop Centricity Business applications work with only minimal setup changes within Internet Security. We recommend changing Internet Security default settings only when non-default settings provide significant benefits. If, however, you are running other web-based applications that require special settings, you need a more sophisticated approach to managing security on the desktop than that outlined in this document. Security settings in the security zone used to access the Centricity Framework server (and application servers if there are any) are the settings that matter. Microsoft Default s Before you apply any of the recommended changes listed below, force default settings by clicking the Default button for each security zone (Internet, Local intranet, or ), and for Advanced, then Apply and OK. Internet security rarely, if ever, has all of the default settings, even when delivered directly from Microsoft. Internet Security s The following table describes the recommended security settings. settings that differ from Microsoft default settings are highlighted in red. To review/modify Internet Security s go to Control Panel/Internet Options/Security Tab.

9 Desktop Internet Security s 9 IE 7.0 Usage and Limitations IE 8.0 The Web Client supports IE7 with the following exceptions: 1. Centricity Business does not support being used in conjunction with active use of multiple IE7 Tabs. It does not require that tabs be disabled in IE7 settings, just that users understand that if the IE7 browser session is to be used with Centricity Business, there should be no concurrent usage of multiple tabs in that session. You may wish to disable Tabs to avoid issues. To do this, access Control Panel/Internet options, select Tabs, then s, and uncheck Tabbed Browsing. 2. Centricity Business does not support ensuring proper display and navigation in conjunction with using the IE7 Page Zoom feature. 3. Centricity Business does not support IE7 installed on Windows Server 2003 SP1 environments that are used as the Framework Server (that is, within the Application Server Tier).

13 Desktop Internet Security s 13 IE 8.0 Usage and Limitations 1. IE 8.0 Compatibility Mode is not required and does not need to be turned on. Under Tools, Compatibility View should not be checked. 2. If you are using Centricity Business Reporter, Cognos must be at version 8.4 to be compatible with IE 8.0. Additionally, The Cognos URL must be added to the Sites for the and Local intranet zones. The XSS filter Security Internet Option (found under Scripting) must be disabled for the and Local intranet zones (see table above). 3. All limitations listed under IE 7.0 Usage and Limitations apply to IE 8.0 as well. Downloading Signed ActiveX Controls A user must have local Admin rights to download and install ActiveX. The Prompt setting for the Download Signed ActiveX Controls property causes a dialog box to be presented to the user when a component must be downloaded, unless Previous component(s) signed by the same digital certificate have already been downloaded, and The check box Always trust content from IDX Systems Corporation is checked. The setting for this property allows download and installation of ActiveX without the user having to confirm the download every time. This setting does not matter on a locked-down desktop that receives updates from either Active Directory or the Desktop Components install kit.

14 14 Desktop Internet Security s Additional Security Recommendations General Recommendations Centricity Business recommends that you: Include your Centricity Framework server(s) in the zone. Use Fully Qualified Domain Names to refer to your servers. Using a Shortcut to Launch Centricity Business If you are accessing Centricity Business products using the Internet Explorer browser, use a target like "C:\Program Files\Internet Explorer\iexplore.exe" to define a shortcut to launch Centricity Business. This ensures that a new iexplorer.exe process is started, and thus gives the new window completely clean context. If you are accessing Centricity Business products using smart client, you use the desktop shortcut created during smart client deployment for access. Google Toolbar Plug-in for Internet Explorer, other Pop-up Blockers The Google Toolbar has a pop-up blocker. Centricity Business web applications use pop-ups. Therefore, to ensure that the applications operate properly, enable ( whitelist ) pop-ups from the Centricity Framework server(s). Any other application that blocks pop-ups within the browser must be configured to allow pop-ups from the Centricity Framework server(s). Pop-up blocking should be disabled with IE7 and IE8 (Tools/Pop-up blocking; uncheck). Using Trusted Sites List to Manage Security () By default, URLs with no domain (for example, use the Local intranet zone security (simple domain name) URLs with domain (for example, use the Internet zone security (Fully Qualified Domain Name) URLs can be added to the Sites list for each zone to change default behavior. We recommend that you configure your systems so that Centricity Business is secured by running in the zone. To do this, set security in this zone correctly, then add the URL of your Centricity Framework server (or Content switch) to the list.

15 Desktop Internet Security s 15 Simple and Fully Qualified DNS names are independent; therefore both addresses, as well as the enumerated IP address, must be listed to cover all possible references. Various wild cards are allowed; for example, you can add *://*.yourorg.yourtld and *:// to the list to allow both http and https. Simple domain names cannot be wildcarded. For more details, see documentation for the Group Policy editor (gpedit.msc) included with each version of Internet Explorer. Using Group Policy Objects to Manage Security s Configuring.Net CLR Programmatically Microsoft s Technet provides articles on managing configuration with Group Policies. Policy settings for controlling URL Actions are available in both the Computer Configuration and the User Configuration nodes of Group Policy Object Editor, in Administrative Templates\Windows Components\Internet Explorer\Internet Control Panel\Security Page..NET CLR should be configured using code similar to that provided in the sample Dotnet2.0_trust.bat file included in the desktop components kit.
