Adding Trusted Sites In Edge4/17/2021
Unfortunately, building such an escape hatch is also the recipe for accumulating technical debt and permitting the corporate intranets to rust to the point that they barely resemble the modern public web.When making a decision, the browser would first map the execution context (site) to a Zone, then consult the setting for that URLAction for that Zone to decide what to do.
This allowed Microsoft IT, for instance, to configure the browser with rules like Treat as a part of my Intranet and allow popups and file downloads without warning messages. In particular, the browser would assign dotless hostnames (e.g. Intranet Zone, and if a Proxy Configuration script was used, any sites configured to bypass the proxy would be mapped to the Intranet Zone. In relatively rare cases, the host application might supply its own Security Manager and override URL Policy decisions for embedded Web Browser Control instances. Users might manually set configuration options to unsafe values without realizing it. Attempts to automatically provide isolation of cookies and other data by Zone led to unexpected behavior, especially for federated authentication scenarios. Users were often completely flummoxed to find that the same page on a single server behaved very differently depending on how they referred to it e.g. Intranet Zone) vs. Internet Zone). A sites Zone can change at runtime without restarting the browser (say, when moving a laptop between home and work networks, or when connecting or disconnecting from a VPN). An IT Department might not realize the implications of returning DIRECT from a proxy configuration script and accidentally map the entire untrusted web into the highly-privileged Intranet Zone. Microsoft IT accidentally did this circa 2011). Some features like AppContainer Network Isolation are based on firewall configuration and have no inherent relationship to the browsers Zone settings. Zone to URLAction mappings were hardcoded into the browser, ignoring group policies and settings in the Internet Control Panel. The performancedeadlock risks mentioned earlier ( Intranet Zone mappings can come from a system-discovered proxy script). Zones are Windows-only (meaning they prevent drop-in replacement of ChromeOS). Those IEMode tabs are really running Internet Explorer, and they use Zones for everything that IE did. On downlevel operating systems (Windows 788.1), logging into the browser for sync makes use of a Windows dialog box that contains a Web Browser Control (based on MSHTML) that loads the login page. Oops. Allow ClickOnceDirectInvoke Auto-opening Downloads from the Intranet without a prompt. Previously, Edge (Spartan)IE respected the FTAOpenIsSafe bit in the EditFlags for the application.manifest progid if-and-only-if the download source was in the IntranetTrusted Sites Zone. Allow launching application protocols from the Intranet without a prompt. Drop all Referers when navigating from the Intranet to the Internet; leave Referers alone when browsing the Intranet. Internet Explorer and legacy Edge will automatically send your client certificate to Intranet sites that ask for it. The AutoSelectCertificateForUrls policy permits Edge to send a client certificate to specified sites without a prompt, but this policy requires the administrator to manually list the sites. Block all (or most) extensions from touching Intranet pages to reduce the threat of data leaks.
