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

When Microsoft Office files are opened from trusted locations, all the content in the files is enabled and active. Users are not notified about any potential risks that might be contained in the files, such as unsigned macros, ActiveX controls, or links to content on the Internet.

The Windows Rights Management Add-on for Internet Explorer provides a way for users who do not use the 2013 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, representing the risk of documents being read by those without the rights and not intended to have access to the document.System AdministratorInformation Assurance Officer

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. This feature does not collect users' names, addresses, or any other identifying information except the IP address that is used to send the data.
By default, users have the opportunity to opt into participation in the CEIP the first time they run an Office application. If an organization has policies that govern the use of external resources such as the CEIP, allowing users to opt in to the program might cause them to violate these policies.System AdministratorInformation Assurance Officer

Discussion

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). If an organization has policies that govern the use of external resources such as the CEIP, allowing the use of the "Help Improve Proofing Tools" feature might cause them to violate these policies.System AdministratorInformation Assurance Officer

An XML expansion pack is the group of files that constitutes a Smart Document in Excel and Word. One or more components that provide the logic needed for a Smart Document are packaged 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, the locations of all files that make up the XML expansion pack are specified, as well as information that instructs Office 2013 how to set up the files for the Smart Document. The XML expansion pack can also contain information about how to set up other 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. Office applications can load an XML expansion pack manifest file with a Smart Document.System AdministratorInformation Assurance Officer

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 could mean 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 is not 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

Each record includes a description of the problem and a link to more information. Inventory and usage data is also tracked. This policy setting allows the data collection features in Office that are used by the Office Telemetry Dashboard and Office Telemetry Log to be turned on. If this policy setting is enabled, Office Telemetry Agent and Office applications will collect telemetry data, which includes Office application usage, most recently used Office documents (including file names) and solutions usage, compatibility issues, and critical errors that occur on the local computers. Office Telemetry Dashboard can be used to view this data remotely, and users can use Office Telemetry Log to view this data on their local computers. If this policy setting is disabled or not configured, the Office Telemetry Agent and Office applications do not generate or collect telemetry data.System AdministratorInformation Assurance Officer

Checks

Verify the policy value for User Configuration >> Administrative Templates >> Microsoft Office 2013 >> Telemetry Dashboard >> "Turn on telemetry data collection" is set to "Enabled".

Use the Windows Registry Editor to navigate to the following hive:
HKEY_Users

For every users profile hive under HKEY_Users, navigate to the following key:
\software\policies\Microsoft\office\15.0\osm

If the value “enablelogging” for user profile hive is REG_DWORD = 1, this is not a finding.
