Discussion

ActiveX controls can adversely affect a computer directly. In addition, malicious code can be used to compromise an ActiveX control and attack a computer. To indicate the safety of an ActiveX control, developers can denote them as Safe For Initialization (SFI). SFI indicates a control is safe to open and run, and it is not capable of causing a problem for any computer, regardless of whether it has persisted data values or not. If a control is not marked SFI, it is possible the control could adversely affect a computer—or it could mean the developers did not test the control in all situations and are not sure whether it might be compromised in the future. By default, if a control is marked SFI, the application loads the control in safe mode and uses persisted values (if any). If the control is not marked SFI, the application loads the control in unsafe mode with persisted values (if any), or uses the default (first-time initialization) settings. In both situations, the Message Bar informs users the controls have been disabled and prompts them to respond. System AdministratorInformation Assurance Officer

The blogging feature in Office products enables users to compose blog entries and post them to their blogs directly from Office, without using any additional software. By default, users can post blog entries to any compatible blogging service provider, including Windows Live Spaces, Blogger, a SharePoint or Community Server site, and others. If your organization has policies that govern the posting of blog entries, allowing users to access the blogging feature in Office might enable them to violate those policies.

The Windows Rights Management Add-on for Internet Explorer provides a way for users who do not use the 2010 Office release to view, but not alter, files with restricted permissions. By default, IRM-enabled files are saved in a format that cannot be viewed by using the Windows Rights Management Add-on. If this setting is enabled, an embedded rights-managed HTML version of the content is saved with each IRM-enabled file, which can be viewed in Internet Explorer using the add-on.

Having access to updates, add-ins, and patches on the Office Online Web site can help users ensure computers are up to date and equipped with the latest security patches. However, to ensure updates are tested and applied in a consistent manner, many organizations prefer to roll out updates using a centralized mechanism such as Microsoft Systems Center or Windows Server Update Services. By default, users are allowed to download updates, add-ins, and patches from the Office Online Web site to keep their Office applications running smoothly and securely. If your organization has policies that govern the use of external resources such as Office Online, allowing users to download updates might cause them to violate these policies.

Discussion

The Message Bar in Office applications is used to identify security issues, such as unsigned macros or potentially unsafe add-ins. When such issues are detected, the application disables the unsafe feature or content and displays the Message Bar at the top of the active window. The Message Bar informs the users about the nature of the security issue and, in some cases, provides the users with an option to enable the potentially unsafe feature or content, which could harm the user's computer. By default, if an Office application detects a security issue, the Message Bar is displayed. However, this configuration can be modified by users in the Trust Center.

When users choose to participate in the Customer Experience Improvement Program (CEIP), Office applications automatically send information to Microsoft about how the applications are used. This information is combined with other CEIP data to help Microsoft solve problems and to improve the products and features customers use most often.

The Help Improve Proofing Tools feature collects data about use of the Proofing Tools, such as additions to the custom dictionary, and sends it to Microsoft. After about six months, the feature stops sending data to Microsoft and deletes the data collection file from the user's computer. Although this feature does not intentionally collect personal information, some of the content sent could include items that were marked as spelling or grammar errors, such as proper names and account numbers. However, any numbers such as account numbers, street addresses, and phone numbers are converted to zeroes when the data is collected. Microsoft uses this information solely to improve the effectiveness of the Office Proofing Tools, not to identify users. By default, this feature is enabled, if users choose to participate in the Customer Experience Improvement Program (CEIP).

An XML expansion pack is the group of files that constitutes a Smart Document in Excel and Word. You package one or more components that provide the logic needed for a Smart Document by using an XML expansion pack. These components can include any type of file, including XML schemas, Extensible Stylesheet Language Transforms (XSLTs), dynamic-link libraries (DLLs), and image files, as well as additional XML files, HTML files, Word files, Excel files, and text files. The key component to building an XML expansion pack is creating an XML expansion pack manifest file. By creating this file, you specify the locations of all files that make up the XML expansion pack, as well as information that instructs 2007 Office how to set up the files for your Smart Document. The XML expansion pack can also contain information about how to set up some files, such as how to install and register a COM object required by the XML expansion pack. XML expansion packs can be used to initialize and load malicious code, which might affect the stability of a computer and lead to data loss.

ActiveX controls are Component Object Model (COM) objects and have unrestricted access to users' computers. ActiveX controls can access the local file system and change the registry settings of the operating system. If a malicious user repurposes an ActiveX control to take over a user's computer, the effect could be significant. To help improve security, ActiveX developers can mark controls as Safe For Initialization (SFI), which means that the developer states that the controls are safe to open and run and not capable of causing harm to any computers. If a control is not marked SFI, the control could adversely affect a computer—or it's possible the developers did not test the control in all situations and are not sure whether their control might be compromised at some future date. SFI controls run in safe mode, which limits their access to the computer. For example, a worksheet control can both read and write files when it is in unsafe mode, but perhaps only read from files when it is in safe mode. This functionality allows the control to be used in very powerful ways when safety wasn't important, but the control would still be safe for use in a Web page. If a control is not marked as SFI, it is marked Unsafe For Initialization (UFI), which means that it is capable of affecting a user's computer. If UFI ActiveX controls are loaded, they are always loaded in unsafe mode. System AdministratorInformation Assurance Officer

When saving documents as Web pages, Excel, PowerPoint, and Word can save vector–based graphics in Vector Markup Language (VML), which enables Internet Explorer to display them smoothly at any resolution. By default, when saving VML graphics, Office applications also save copies of the graphics in a standard raster file format (GIF or PNG) for use by browsers that cannot display VML. If the Rely on VML for displaying graphics in browsers check box in the Web Options dialog box is selected, applications will not save raster copies of VML graphics, which means those graphics will not display in non-Microsoft browsers.

Office files can save graphic files in Portable Network Graphics (PNG) format to improve the quality of the graphics when documents are saved as Web pages. The PNG graphic file format (.png) is used for a wide range of graphics, from small images (such as bullets and banners) to complex images (such as photographs), and can offer better image fidelity and smaller file sizes than some other formats. However, PNG graphics cannot be displayed by many earlier Web browsers, such as Microsoft Internet Explorer® version 5 or earlier. Office applications do not save graphics in the PNG format. To change this functionality, users can open the application's Options dialog box, click Advanced, click Web Options, and then select the Allow PNG as a graphics format check box. This setting can be used to guard against theoretical future zero-day attacks that might target PNG files. System AdministratorInformation Assurance OfficerECSC-1
