Dialog box location
On the Tools menu, click Options, and then click the Security tab.
Privacy options section
Remove information from file properties on save Selecting this check box specifies that when you save your project file, the Author, Manager, Company, and Last Saved By fields are cleared from the Properties dialog box (File menu). This helps protect your privacy and that of your company if you are distributing your project file, or if unauthorized individuals access the project file. By default, this check box is cleared.
Selecting this check box applies only to the active project file, and not to any existing or newly created document. You need to select this check box for each individual project file whose personal information you want to remove. Note that only the four fields are removed. Other personal information may still be present in the file and might need to be deleted manually.
Macro security section
Macro Security Opens the Security dialog box, which you can use to set the security level (Very High, High, Medium, or Low). By default, the security level for macros is High, indicating that only signed macros from trusted sources are allowed to run. Any unsigned macros are automatically disabled. You can also use the Security dialog box to view, add, and remove trusted sources for macros and other add-ins used in the active project file.
Require Project Server and Workspace sites to be added to the Internet Explorer Trusted Sites list check box
Require Project Server and Workspace sites to be added to the Internet Explorer Trusted Sites list Selecting this check box ensures that any Project Server or Workspace sites you specify on the Collaborate tab of the Options dialog box will be added to the Windows Internet Explorer Trusted Sites list. This prevents access problems to your Project Server or Workspace due to your security settings. To see the list of Web sites that you trust not to damage your computer, in any Windows Internet Explorer window, click Internet Options on the Tools menu. On the Security tab, click Trusted sites, and then click Sites.
