Discussion

The Uniform Resource Locator (URL) standard allows user authentication to be included in URL strings in the form http://username:[email protected] A malicious user might use this URL syntax to create a hyperlink that appears to open a legitimate Web site but actually opens a deceptive (spoofed) Web site. For example, the URL http://[email protected] appears to open http://www.wingtiptoys.com but actually opens http://example.com. To protect users from such attacks, Internet Explorer usually blocks any URLs using this syntax. This functionality can be controlled separately for instances of Internet Explorer spawned by Office applications (for example, if a user clicks a link in an Office document or selects a menu option that loads a Web page). If user names and passwords in URLs are allowed, users could be diverted to dangerous Web pages, which could pose a security risk. System AdministratorInformation Assurance Officer

Internet Explorer performs a number of safety checks before initializing an ActiveX control. It will not initialize a control if the kill bit for the control is set in the registry, or if the security settings for the zone in which the control is located do not allow it to be initialized. This functionality can be controlled separately for instances of Internet Explorer spawned by Office applications (for example, if a user clicks a link in an Office document or selects a menu option that loads a Web page). A security risk could occur if potentially dangerous controls are allowed to load. Information Assurance OfficerSystem Administrator

Typically, when Internet Explorer loads a Web page from a Universal Naming Convention (UNC) share that contains a Mark of the Web (MOTW) comment, indicating the page was saved from a site on the Internet, Internet Explorer runs the page in the Internet security zone instead of the less restrictive Local Intranet security zone. This functionality can be controlled separately for instances of Internet Explorer spawned by Office applications (for example, if a user clicks a link in an Office document or selects a menu option that loads a Web page). If Internet Explorer does not evaluate the page for a MOTW, potentially dangerous code could be allowed to run.Information Assurance OfficerSystem Administrator

When an Office Open XML document (Word, Excel, and PowerPoint) is rights-managed, or password-protected, any macros embedded in the document are encrypted along with the rest of the contents. By default, these encrypted macros will be disabled unless they are scanned by antivirus software immediately before being loaded. If this default configuration is modified, Office products will not require encrypted macros to be scanned before loading.

When users create new PowerPoint files, PowerPoint 2010 saves them in the new *.pptx format. Ensure this setting is enabled to specify that all new files are created in PowerPoint 2010. If a new file is created in an earlier format, some users may not be able to open or use the file, or they may choose a format this is less secure than the PowerPoint 2010 format. Users can still select a specific format when they save files, but they cannot change default of this setting from the PowerPoint Options dialog box.

VSTO projects require access to the Visual Basic for Applications project system in Excel, PowerPoint, and Word, even though the projects do not use Visual Basic for Applications. Design-time support of controls in both Visual Basic and C# projects depends on the Visual Basic for Applications project system in Word and Excel. By default, Excel, Word, and PowerPoint do not allow automation clients to have programmatic access to VBA projects. Users can enable this by selecting the Trust access to the VBA project object model in the Macro Settings section of the Trust Center. However, doing so allows macros in any documents the user opens to access the core Visual Basic objects, methods, and properties, which represents a potential security hazard.

PowerPoint presentations that are saved in standard or HTML format can contain a flag indicating whether markup (comments or ink annotations) in the presentation should be visible when the presentation is open. PowerPoint ignores this flag when opening a file, and always displays any markup present in the file. In addition, when saving a file, PowerPoint sets the flag to display markup when the presentation is next opened. If this default configuration is changed, PowerPoint sets the flag according to the state of the Show Markup option on the Review tab of the Ribbon when it saves presentations in standard or HTML format. In addition, PowerPoint enables or disables the Show Markup option according to the way the flag is set when it opens files, which means that a presentation saved with hidden markup is opened with the markup still hidden. If a file is saved with hidden markup, users might inadvertently distribute sensitive comments or information to others via the presentation file. Information Assurance OfficerSystem Administrator

Data Execution Prevention (DEP) is a set of hardware and software technologies performing additional checks on memory to help prevent malicious code from running on a system. The primary benefit of DEP is to help prevent code execution from data pages. Enabling this setting, turns off Data Execution Prevention. As a result, malicious code takes advantage of code injection or buffer overflow vulnerabilities possibly exploiting the computer.System AdministratorInformation Assurance Officer

This setting controls whether users can link slides in a presentation with their counterparts in a PowerPoint Slide Library. If you enable this policy setting, PowerPoint cannot check the status of a slide in a Slide Library when a presentation with Slide Update data is opened. If you disable or do not configure this policy setting, each time users open a presentation that contains a shared slide, PowerPoint notifies them if the slide has been updated and provides them with the opportunity to ignore the update, append a new slide to the outdated slide, or replace the outdated slide with the updated one.System AdministratorInformation Assurance Officer
