Description
Incognito mode allows the user to browse the Internet without recording their browsing history/activity. From a forensics perspective, this is unacceptable. Best practice requires that browser history is retained. The "IncognitoModeAvailability" setting controls whether the user may utilize Incognito mode in Google Chrome. If 'Enabled' is selected or the policy is left unset, pages may be opened in Incognito mode. If 'Disabled' is selected, pages may not be opened in Incognito mode. If 'Forced' is selected, pages may be opened ONLY in Incognito mode. 0 = Incognito mode available. 1 = Incognito mode disabled. 2 = Incognito mode forced.
