Security Features

Enterprise Browser 2.5

Overview

Enterprise Browser offers numerous security features implemented in various ways and through different interfaces. Below is a summary of EB security features with links to the relevant documentation for each.

Basic/Digest Authentication

Enterprise Browser supports pages that are password-protected with basic and digest authentication. The tags for this feature are located in the <authentication> node of the EB app's config.xml file.

Client and Server Certificates

Enterprise Browser supports access to web sites that are protected with client- or server-side certificates. This is documented in the <Certificates guide>.

Compliance with TLS 1.2, SSL3

Enterprise Browser supports Secure Sockets Layer (SSL) and the newer Transport Layer Security (TLS) protocols, detailed in the EB Compliance Guide.

Device Lock-down

When tight control over device settings and/or apps is required, Enterprise Browser 1.6 and higher integrates with Enterprise Home Screen, Zebra's free Android device lock-down solution.

See the Enterprise Browser Device Lock-down Guide for complete instructions.

Also see Kiosk Mode Enhancements, below.

Security Config Tags

The following security features can be implemented in an app's config.xml file.

Web Security Features
  • <ApplicationCacheEnabled> - allows an HTML5 app to be stored locally for added security, off-line operation, improved speed and reduced server load.
  • <ApplicationCacheOnExit> - erases a cached HTML5 app upon exiting it.
  • <SetCacheMode> - controls rules for loading pages from cache vs. loading from the server.
  • <DeleteCacheOnExit> - erases cached data upon exiting.
  • <DomStorageEnabled> - controls whether application data is stored locally using HTML5 Web Storage.
  • <DatabaseEnabled> - controls whether to enable the WebSQL database.
  • <GeoLocationEnabled> - controls whether location data from device sensors can be consumed by the EB app.
  • <JavascriptEnabled> - permits JavaScript code execution within an EB app to be toggled on and off.
  • <SaveFormData> - determines whether an app will retain data entered by a user into forms, checkboxes and other input elements.
  • <BlockNetworkImage> - prevents the app from loading images over a network while allowing non-image resources to load.
  • <BlockNetworkLoads> - prevents the app from loading all network resources, including images.
  • <ClearWebData> - determines whether WebView data stored by the EB app will be retained when app returns to the foreground after the device HOME key is pressed.
  • <NavigateToHomePage> - causes an EB app to display its Start Page when the app returns to the foreground.
  • <MixedContentMode> - security feature that can prevent loading of content from insecure sites.
  • <WebFilteringEnabled> - controls whether web sites will be filtered by the addresses specified in the related tags (below).
  • <WhiteListingUrls> - explicitly allows one or more websites to be visited by an app.
  • <BlackListingUrls> - explicitly blocks one or more websites.
  • <DeleteCookiesOnExit> - automatically erases cookies stored by Enterprise Browser when exiting.
  • <ExitPasswordEnabled> tag - forces the app to require a password to exit.
Kiosk Mode Enhancements

The following tags work only on devices running Android Lollipop (and higher). These features are intended to enhance Kiosk Mode, a Lollipop feature that restricts device usage to a single app. The tags also work independently.

  • <setHomeKeyDisable> - prevents the HOME key (or capacitive button) on the device from exiting the current app.
  • <setStatusBarDisable> - prevents the status bar from being displayed (either automatically or by dragging down from the top of the screen).
  • <setBackKeyDisable> - disables the BACK key (or capacitive button), which could otherwise exit the current app and invoke the previously active app or Launcher screen.
  • <setVolumeButonDisable> - prevents the user from controlling the speaker volume using device hardware keys.
  • <setRecentAppDisable> - prevents display of the Recent Apps list, which could otherwise allow the user exit the current app by selecting an app from the "recents" list.

Settings Lock-out

An EB app can prevent a user from accessing the Settings panel on a device by using the <SettingsPageProtectionEnabled> tag in the EB app's config.xml file
